RESUMO

BACKGROUND: The survival of ART restorations can be influenced by the choice of the restorative material. The aim of this randomized non-inferiority controlled trial was to compare the 2-year survival rate and cost analysis of two encapsulated glass ionomer cements (GIC) as occlusoproximal restorative materials in primary molars. METHODS: Children from public schools in Tietê (Brazil), aged 4-8 years with occlusoproximal dentine carious lesions in primary molars were selected and randomly assigned to receive either Equia Forte (EF) or Riva Self Cure (RSC) as restorative materials. Treatment was carried out by two trained final-year dental students in schools following ART premises. Restorations were assessed by a trained and calibrated examiner after 2, 6, 12, 18, and 24 months. The primary outcome was restoration survival after 2 years, analyzed using Kaplan-Meier survival and Cox regression analysis (α = 5%). Professional and materials costs for each group were collected in Brazilian Reais (R$) and converted into US dollars (US$) and analyzed using Monte-Carlo simulation. RESULTS: A total of 152 children (76 per group) were included in the study, and 121 (79%) were evaluated after 2 years. The overall 2-year restoration survival rate was 39% (EF = 45%; RSC = 32%) with no difference between the groups. The baseline and 2-year total cost of restorations using RSC was lower when compared to EF (incremental cost: US$ 6.18). CONCLUSION: After two years of follow-up, Riva Self Cure shows comparable restoration survival rates to Equia Forte, being more cost-effective in the Brazilian perspective. TRIAL REGISTRATION: This randomized clinical trial was registered on ClinicalTrials.Gov - NCT02730000.

RESUMO

Aim: This study evaluated the short-term clinical and microbiological performance of resin-modified glass ionomer cement (RM-GIC) cement containing chlorhexidine (CHX) for atraumatic restorative treatment (ART) in primary teeth. Materials and methods: The clinical trial was conducted in 36 children that received ART in primary molars either with GIC (group I, n = 18) or GIC containing 1.25% CHX (group II, n = 18). The survival rate of restorations was checked 7 days, 3, and 6 months after their application when saliva and biofilm were collected for microbiological assessment of mutans streptococci (MS) counts. Data were analyzed using the Kruskal-Wallis/Mann-Whitney U tests for clinical analysis and microbiological evaluations (p < 0.05). Results: The survival rate of restorations was similar comparing groups I with II. Microbiological analysis showed a significant reduction in MS levels 7 days after the treatment in both saliva and biofilm of children treated with RM-GIC containing CHX (group II); however, MS counts at 3 and 6 months did not differ from the initial counts. Conclusion: A total of 1.25% CHX improved the microbiological properties of GIC in the short term without impairing the clinical performance of ART restorations. Clinical significance: Glass ionomer cement (GIC) containing CHX could be an alternative in ART procedures with the objective of promoting an additional antimicrobial effect, which is interesting for children with high counts of MS during the initial phase of adaptation to dental treatment.

RESUMO

This scoping review aimed to identify, describe, and analyze the use of Atraumatic Restorative Treatment (ART) as public policy. Inclusion criteria: studies on public oral health policies; dental caries; ART. Exclusion criteria: clinical studies; specific interventions; studies that report public policies that do not use ART as a strategy for caries treatment. The search was conducted in PubMed, BVS, Epistemonikos, Health Systems Evidence, and Rxforchange. The selection process and data extraction were performed by two authors independently according to the stages and categories of a conceptual framework. Of the 2253 eligible articles, 139 were duplicates, and 1680 were not included after reading the title and abstract. After assessing the full text, 414 articles were excluded. Twenty articles were included. Nineteen were conducted in nine countries (South Africa, Bolivia, Cambodia, Egypt, Mexico, Tanzania, East Timor, Tunisia, and Zimbabwe), and one in the Americas. The studies reported high prevalence of dental caries and lack of access to restorative procedures in health services as common problems. Policy developments followed a similar process, with the presence of governments, conceptual use of scientific evidence, and induction by the World Health Organization. Regarding implementation barriers, the included studies mentioned the lack of supplies and lack of induction by managers,while in relation to the facilitators, permanent education and professional practice were mentioned. Cohort studies have shown a survival rate greater than 80% after one year of follow up of the restorations performed. The findings of this review indicate that the use of ART in public policies is promising, however, its use is still in an early stage. (AU)

Critérios de inclusão: estudos sobre políticas públicas de saúde bucal; cáries dentárias; ART. Critérios de exclusão: estudos clínicos; intervenções específicas; estudos que relatam políticas públicas que não utilizam o ART como estratégia para o tratamento de cárie. A pesquisa foi realizada no PubMed, BVS, Epistemonikos, Health Systems Evidence e Rxforchange. O processo de seleção e extração de dados foram realizados por dois autores, de forma independente, de acordo com as etapas e categorias de um quadro conceitual. Dos 2.253 artigos elegíveis, 139 eram duplicados e 1.680 não foram incluídos após a leitura do título e do resumo. Após avaliação do texto completo, foram excluídos 414 artigos. Vinte artigos foram incluídos. Dezenove foram realizados em nove países (África do Sul, Bolívia, Camboja, Egito, México, Tanzânia, Timor Leste, Tunísia e Zimbábue) e um nas Américas. Os estudos relataram alta prevalência de cárie dentária e falta de acesso a procedimentos restauradores nos serviços de saúde como problemas comuns. Os desenvolvimentos de políticas seguiram um processo semelhante, com a presença de governos, uso conceitual de evidências científicas e indução da Organização Mundial da Saúde. Quanto às barreiras de implementação, foram mencionadas a falta de insumos e a falta de indução por parte dos gestores. Quanto aos facilitadores, foram citados a educação permanente e a prática profissional. Estudos de coorte mostraram sobrevida superior a 80% após um ano de acompanhamento. Os achados desta revisão indicam que a utilização da ART nas políticas públicas é promissora, porém, sua utilização ainda é incipiente. (AU)

RESUMO

A fobia odontológica afeta considerável parcela da população, a ansiedade e medo frente ao tratamento dentário induzem pacientes ao cancelamento ou adiamento de tratamentos essenciais, agravando assim o seu quadro clínico. As abordagens restauradoras minimamente invasivas preconizam maior preservação dos tecidos dentários, diminuindo o desconforto e dor durante as intervenções. Sob esta ótica o Tratamento Restaurador Atraumático (ART) dispensa o uso das turbinas rotatórias, da anestesia local, do isolamento absoluto e utiliza o Cimento de Ionômero de Vidro de alta viscosidade nas restaurações. A relevância do ART no panorama odontológico e sua ampla utilização nos serviços públicos e privados de assistência bucal justificam a realização desta revisão narrativa de literatura, realizada a partir de artigos publicados nos últimos dois anos, acessados nas bases de dados online Scientific Eletronic Library On-line (SciELO), MEDLINE e LILACS. Esta pesquisa tem como objetivo reconhecer a fobia odontológica e associá-la à indicação do ART assim como definir a efetividade desta proposta de intervenção, colaborando para seu uso de forma criteriosa e adequada.

Dental phobia affects a considerable portion of the population, anxiety and fear regarding dental treatment induce patients to cancel or postpone essential treatments, thus aggravating their clinical condition. Minimally invasive restorative approaches advocate greater preservation of dental tissue, reducing discomfort and pain during interventions. From this perspective, the Atraumatic Restorative Treatment (ART) dispenses with the use of rotating turbines, local anesthesia, absolute isolation and uses high viscosity Glass Ionomer Cement in restorations. The relevance of ART in the dental panorama and its wide use in public and private oral care services justify this narrative literature review, based on articles published in the last two years, accessed in the online databases Scientific Electronic Library On- line (SciELO), MEDLINE and LILACS. This research aims to recognize dental phobia and associate it with the indication of ART, as well as to define the effectiveness of this intervention proposal, contributing to its judicious and appropriate use.

RESUMO

O objetivo do presente estudo foi apresentar um relato de experiência com utilização de Odontologia Minimamente Invasiva em intervenção, tratamento e prevenção de cárie em crianças de escola pública por meio da integração de uma Instituição de Ensino Superior com o sistema público de saúde e comunidade. Para tal ação, a intervenção foi dividida em: Fase 1 -aplicação funcional das diretrizes de atendimento odontológico seguindo o Tratamento Restaurador Atraumático (ART) e Fase 2 -análise crítica da efetividade das ações da fase 1, para potencial reprodução sob contexto de retomada das atividades escolares presenciais. Na Fase 1, graduandos do último período de Odontologia de uma universidade estadual realizaram o levantamento clínico e atendimento com a técnica do ART em 275 pacientes provenientes de uma escola da rede pública municipal de ensino fundamental, em escolares na faixa etária de 6 a 15 anos de idade. A partir da Fase 2 (Análise crítica de efetividade de ações) foi possível reconhecer, por meio de uma análise descritiva das experiências vivenciadas e da avaliação do resultado do primeiro controle realizado dois meses após realização ART, que essa atividade foi efetivamente um modelo desucesso na integração ensino-serviço, capaz de exemplificar uma experiência potencialmente significativa para emprego em contextos de retomada das atividades escolares presenciais, minimizando os problemas gerados pelo distanciamento social e interrupção temporária das consultas eletivas em Odontologia. A integração ensino-serviço com a ação realizada promoveu a qualidade de vida e redução da vulnerabilidade e riscos à saúde bucal (AU).

El presente estudio tuvo como objetivo presentar un relato de experiencia con el uso de la Odontología Mínimamente Invasiva en la intervención, tratamiento y prevención de caries en escolares públicos a través de la integración de una Institución de Educación Superior con el sistema de salud pública y la comunidad. Para esta acción, la intervención se dividió en: Fase 1 -aplicación funcional de las pautas de atención dental siguiendo el Tratamiento Restaurador Atraumático (TRA) y Fase 2 -análisis crítico de la efectividad de las acciones de la fase 1, para la reproducción potencial en el contexto de reanudación de actividades escolares presenciales. En la Fase 1, estudiantes del último período de Odontología de una universidad estatal realizaron la encuesta clínica y atención con la técnica de TRA en 275 pacientes deuna escuela de la red de escuelas primarias públicas municipales, en estudiantes de 6 a 15 años. A partir de la Fase 2 (Análisis crítico de la efectividad de las acciones) se pudo reconocer, mediante un análisis descriptivo de las experiencias vividas y la evaluación del resultado del primer control realizado dos meses después de la realización de la TAR, que esta actividad fue efectivamente un modelo de éxito en la integración enseñanza-servicio, capaz de ejemplificar una experiencia potencialmente significativa para su uso en contextos de reanudación de actividades escolares presenciales, minimizando los problemas generados por el distanciamiento social y la interrupción temporal de las consultas electivas en Odontología. La integración enseñanza-serviciocon la acción realizada promovió la calidad de vida y redujo la vulnerabilidad y los riesgos para la salud bucal (AU).

The aims of this study were to present an experience case report on the use of Minimally Invasive Dentistry in the intervention, treatment, and prevention of dental cavities in children attending public schools through the integration of a Higher Education Institution along with the Brazilian public health system known as Unified Health System, and the community. For this action, the intervention was dividedinto: Phase 1 -application of the dental care guidelines following the Atraumatic Restorative Treatment (ART) and Phase 2 -critical analysis of the effectiveness of phase 1 actions, for potential reproduction under the context of resumption of face-to-face school activities after COVID-19 pandemic. During Phase 1, last period undergraduates of Dentistry from a state university carried out a clinical survey with the ART technique in 275 patients from a public municipal elementary school, in schoolchildrenaged 6 to 15 years old. Based on Phase 2 findings, it was possible to recognize, through a descriptive analysis of the experiences lived and the evaluation of the first follow-up, carried out two months after performing ART, that this initiative was highly successful. It served as a valuable model in the context of resuming face-to-face school activities, mitigating the challenges caused by social distancing measures and the temporary suspension of elective dental appointments due to the pandemic. The education-service integration with the implemented action promoted a better quality of life and reduced vulnerability and risks to oral health (AU).

RESUMO

ABSTRACT Objective: To evaluate the association of oral health-related quality of life (OHRQoL) with the longevity of ART-restorations in children after 18 months. Material and Methods: A longitudinal clinical study with 62 six- to seven-year-old children, both genders, 31 of whom underwent four weeks of oral health education strategy (OHES) followed by ART (GOHES+ART) and the others only ART (GART). The Brazilian short-version of the Child Perceptions Questionnaire (16-CPQ8-10) was used to evaluate the OHRQoL and the perception of change in oral health was assessed by a single question. Data was analyzed using Mann-Whitney, Wilcoxon and Friedman's tests. Results: After 18 months, GOHES+ART reported a greater impairment on OHRQoL, mainly in oral symptoms domain (p<0.05). In this period, greater impairment of oral symptoms was reported in children with failed restorations and with treatment considered to have a minor failure (p<0.05). In inter-group analysis, the GOHES+ART, with 2 to 4 restorations, Class I, of small size, located in the upper arch and with a smaller failure, reported more oral symptoms than the GART. Conclusion: In the long-term, children submitted to OHES followed by ART reported more oral symptoms. Factors such as number, class, size and location of the restorations need to be considered for the implementation of an efficient and effective oral health program, as well as for greater longevity of ART-restorations.

RESUMO

Objetivo: A cárie radicular é um problema da Odontologia moderna, porém é notável a falta de diretrizes sobre o seu manejo. Objetivamos elaborar e adaptar um guia a partir da tradução das recomendações do consenso in-ternacional European Organization for Caries Research (ORCA) e European Federation of Conservative Dentistry (EFCD) para as tomadas de decisão clínica na intervenção do processo de cárie na pessoa idosa, com foco na cárie radicular. Materiais e métodos: O protocolo de tradução das recomendações do consenso internacional consistiu nas etapas: (1) tradução inicial, (2) síntese da tradução, (3) retradução, (4) revisão por comitê de especialistas, com adaptação cultural. A partir da tradução, foi desenvolvido um guia com diretrizes para tratamento de cárie radicular no Brasil. Resultados: Para prevenção de novas lesões é recomendada a escovação diária com dentifrício >1.500ppm/F. Dentifrícios com 5.000ppm/F ou vernizes (>20.000ppm/F) podem ser indicados para paralisar lesões radiculares ativas e para prevenção em pessoas idosas com alta suscetibilidade à cárie radicular, e o Diamino Fluoreto de Prata (>30%) para paralisar lesões ativas. Intervenções invasi-vas diretas são indicadas dependendo da situação clínica. Discussão: Nota-se uma falta de interesse em estudos primários sobre tratamentos para cárie radicular, criando assim uma lacuna em relação ao seu manejo, que reflete no nível de evidência detectado pelo consenso. Conclusão: Guias clíni-cos são importantes para reduzir a lacuna entre a pesquisa e a prática clínica. Essa tradução para o português facilitará o acesso dos dentistas bra-sileiros em relação a evidência consolidada até o momento para o manejo de cárie radicular.

Aim: Root caries are a problem in modern dentistry, but the lack of guidelines regarding their management is notable. We aim to develop and adapt a guide based on the translation of the recommendations of the international consensus as outlined by the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) for clinical decision-making in the intervention of the caries process in the elderly, with a focus on root caries. Materials and methods: The protocol for translating the recommendations of the international consensus consisted of the following steps: (1) initial translation, (2) synthesis of the translation, (3) back-translation, (4) review by an expert committee with cultural adaptation. Based on the translation, a guide was developed with guidelines for the treatment of root caries in Brazil. Results: To prevent new lesions, daily brushing with toothpaste >1,500ppm/F is recommended. Toothpaste with 5,000ppm/F or varnishes (>20,000ppm/F) may be recommended to paralyze active root lesions and for prevention in elderly people with high susceptibility to root caries, and Silver Diamine Fluoride (>30%) to paralyze active lesions. Direct invasive interventions are indicated depending on the clinical situation. Discussion: There is a lack of interest in primary studies on treatments for root caries, thus creating a gap in relation to its management, which is reflected by the level of evidence detected in the consensus. Conclusion: Clinical guidelines are important to reduce the gap between research and clinical practice. This translation into Portuguese will facilitate access by Brazilian dentists to the consolidated evidence gathered to date for the management of root caries.

RESUMO

Background: The clinical performance of new restorative materials must be evaluated before recommending its use in primary teeth. Aim: This randomized clinical trial evaluated the survival rates of restorations in single and occluso-proximal cavities of primary teeth performed with a new dual-cure resin-based material in comparison with a resin-modified glass ionomer cement after 12 months of follow-up. Materials and methods: A total of 107 restorations were placed in 27 children by one experienced pediatric dentist. Two materials were tested: Vitremer and a dual-cure resin-based material with (CentionN+Adh) and without (Cention N-Adh) adhesive system application. Two calibrated and blinded examiners evaluated the restorations at 3, 6, and 12-month. The longevity of the restorations was analyzed using Kaplan-Meier survival curves and Log-rank test (α = 5%). Results: The overall survival rates after 12-month were 81.9% for Vitremer, 70.4% for Cention N+Adh, and 66.7% for Cention N-Adh, which had the poorer performance (HR = 0.54; 95% CI= 0.31-0.95; p = 0.031). When considering the type of the cavities, the difference was significant only for occluso-proximal cavities when Cention N-Adh was used (HR = 0.46; CI = 0.26-0.81; p = 0.008). Conclusion: All evaluated materials are suitable for restoring occlusal cavities after selective caries removal. However, Cention N needs to be used with adhesive in occluso-proximal cavities. Clinical significance: Cention-N can be used for deciduous teeth restorations, with similar longevity rates as resin modified glass ionomer cements.Trial registration number RBR-9nqszr.

RESUMO

Abstract: Appropriate research reports are important to facilitate the evaluation of studies and the decision-making by dentists and policymakers. This meta-research study assessed the conformity of randomized clinical trials (RCTs) on atraumatic restorative treatment (ART) restorations with the CONSORT recommendations and their risk of bias (RoB). Cochrane Library, MEDLINE, BBO, LILACS, Scopus, and Web of Science databases were searched from April 2019 to June 2021 for RCTs that assessed the longevity of ART restorations in children. A specific tool was used to assess adherence to the CONSORT recommendations; RoB was evaluated with the Cochrane risk-of-bias tool. Descriptive analyses included the number of studies by journal, follow-up period, country, and quality assessments. A total of 2,181 papers were retrieved and 36 of them were analyzed qualitatively. The overall CONSORT mean score (CONms) was 22.52 ± 6.17 out of 32 points. The best described items were intervention and outcomes, whereas allocation concealment was described in only 22% of the papers. Significant differences in CONms were detected in the analysis by country and publication dates. High CONms were observed in recently published papers (26.7 ± 3.1) when compared to first ART studies (18.1 ± 4.6; p < 0.001). RoB was low in four studies, unclear in 11, and high in 21. Adherence of the papers to the CONSORT recommendations was not fully achieved and most of the papers had unclear and high RoB (PROSPERO registration #CRD42020201460).

RESUMO

ABSTRACT The commercial bovine bone mineral most commonly used is available in two particle sizes and studies have demonstrated contradictory results regarding bone formation volume using small or large particles. The aim of this systematic review and meta-analysis was to compare the bone formation volume and residual bovine bone volume in sinus floor augmentation using small and large particles. The following outcome measures were assessed: bone formation volume (%) and residual bovine bone particles volume (%) assessed by histomorphometric analysis. The initial screening resulted in 236 records. After removal of duplicated articles and analysis of titles, abstracts and full texts, three articles were included in the meta-analysis. The bone formation volume and residual bovine bone volume did not differ between small and large particles, with low heterogeneity of studies. The particle size of bovine bone mineral did not influence bone formation percentage; small and large particles of bovine bone graft presented similar residual bone mineral; more randomized clinical trials should be performed to completely confirm that bovine bone mineral particle size does not affect the result of sinus floor augmentation.

RESUMO O enxerto ósseo bovino comercial mais comumente utilizado está disponível em dois tamanhos de partícula, que tem demonstrado resultados contraditórios em relação à formação óssea usando partículas pequenas ou grandes. O objetivo desta revisão sistemática e meta-análise é comparar o volume de formação óssea e o volume de enxerto residual em levantamento de seio usando partículas pequenas e grandes. Os seguintes dados foram comparados: volume de formação óssea (%) e volume residual de partículas de enxerto (%) dados por análise histomorfométrica. A seleção inicial resultou em 236 artigos. Após remoção de artigos duplicados e análise dos títulos, resumos e textos completos, três artigos foram incluídos na meta-análise. Os volumes de formação óssea e de enxerto residual não diferenciam entre os tamanhos de partícula pequeno e grande, com baixa heterogeneidade dos artigos. O tamanho de partícula de enxerto ósseo bovino não influencia o percentual de formação óssea; partículas de enxerto ósseo bovino pequenas e grandes apresentaram enxerto residual similar; mais ensaios clínicos randomizados deveriam ser realizados para confirmar que o tamanho de partícula de enxerto não afeta os resultados de levantamento de seio maxilar.

RESUMO

ABSTRACT The treatment of cavity carious lesions in anterior deciduous teeth is a frequent demand in the pediatric dentistry clinic, since the control of the disease in early childhood still presents itself as an inter-factor challenge in child health care. While the scientific evidence on the minimally invasive principles of approach in Dentistry is presented at an increasing level, the alternatives for restorative treatment in anterior deciduous teeth still face the low availability of reports that associate minimal intervention with the aesthetic needs inherent to the treatment. Thus, this article presents a series of cases in which direct restorations in composite resin, without removing carious tissue using polyvinyl matrices, were treatment alternatives for moderate and severe caries lesions in anterior deciduous teeth. It was observed, therefore, that the use of this artifact helped the rehabilitation of compromised dental elements with speed and satisfactory 50 result, suggesting that this is an appropriate approach for application in Pediatric Dentistry, 51 since it offers resistance, durability, besides providing aesthetics and functionality, it presents lower cost and agility as it eliminates the laboratory phase.

RESUMO O tratamento de lesões cavitadas de cárie em dentes decíduos anteriores é uma demanda frequente na clínica de odontopediatria, visto que o controle da doença na primeira infância ainda se apresenta como um desafio interfatorial nos cuidados em saúde infantil. Enquanto a evidência científica nos princípios minimamente invasivos de abordagem em Odontologia apresenta-se em nível crescente, as alternativas para tratamento restaurador em dentes decíduos anteriores ainda esbarram na baixa disponibilidade de relatos que associem a mínima intervenção às necessidades estéticas inerentes ao tratamento. Assim, este artigo apresenta uma série de casos em que as restaurações diretas em resina composta, sem a remoção de tecido cariado utilizando matrizes de polivinila foram alternativas de tratamento para lesões de cárie moderadas e severas em dentes decíduos anteriores. Observou-se que o uso desse artefato auxiliou a reabilitação dos elementos dentários comprometidos com rapidez e resultado satisfatório, sugerindo que essa é uma abordagem adequada para aplicação em Odontopediatria, já que oferece resistência, durabilidade, além de proporcionar estética e funcionalidade, apresenta menor custo e agilidade na medida que dispensa a fase laboratorial.

RESUMO

Objetivo: Esta revisão de escopo teve como objetivo comparar a taxa de sucesso de restaurações confeccionadas com cinco marcas diferentes de Cimento de Ionômero de Vidro de Alta Viscosidade (CIVAV), referência no Tratamento Restaurador Atraumático (Atraumatic Restorative Treatment-ART).Métodos: Buscas no PubMed, Scopus e Web of Science foram feitas. Buscas no OpenGrey e no Google Scholar também foram feitas. Critérios de inclusão foram estudos (ensaios clínicos e estudos de acompanhamento) que avaliavam a taxa de sucesso de restaurações confeccionadas com CIVAV. Não houve restrição de idioma ou data. Título/resumo e texto completo das referências encontradas foram avaliados por dois autores. Referências que preencheram os critérios de inclusão foram selecionadas. Extração de dados foi feita. Modelos de regressão de Cox foram idealizados para comparação da probabilidade de sucesso das restaurações com diferentes tipos de CIVAV. Os resultados foram relatados em razão das chances (RC) e intervalos de confiança (IC). Análises de Kaplan Meyer foram feitas para o cálculo da probabilidade de sucesso de restaurações com CIVAV. Resultados: Nove artigos avaliando o ChemFil Rock, ChemFlex, Equia Fil, Ketac Molar ou Fuji IX foram incluídos. Restaurações com cimentos de ionômero de vidro Fuji IX (RC = 3,51; IC = 1,96 ­ 6,28), Ketac Molar (RC = 4,01; IC = 2,40-6,68) e ChemFlex (RC = 4,20; IC = 1,01-17,66) apresentaram uma taxa de sucesso significativamente maior do que aquelas com ChemFil Rock. EquiaFil alcançou a segunda menor eficácia, ligeiramente maior que o ChemFil Rock. Conclusão:Restaurações com Fuji IX, Ketac Molar e ChemFlex apresentaram altas taxas de sucesso ao longo do tempo de avaliação do ART.

RESUMO

ABSTRACT In Dentistry, any user with one or more limitations, of temporary or permanent mental nature, of physical, sensory, emotional or medical growth, is considered to be a Patient with Special Needs, preventing him from being subjected to a conventional dental situation. These patients form a group which may be considered at high risk for the development of oral diseases, according to the kind of pathogen. Among them, is the Williams-Beuren Syndrome, a rare congenital disease with cardiovascular involvement, mental retardation, dysmorphic face, idiopathic hypercalcemia, musculoskeletal problems, dental and growth anomalies. Familial and sporadic cases are thought to result from deletion of genetic material from adjacent genes located on the long arm of chromosome 7. This article reports a clinical case involving a four-year-old boy with Williams-Beuren Syndrome, referred to the clinic of the Specialization Course for Patients with Special Needs, at the São Leopoldo Mandic Dental Research Center, Campinas (SP). As the patient was resistant to dental care, in order to reduce anxiety and increase collaboration in clinical sessions, the Hixizine® medication was administered. For atraumatic restorative treatment and restorations, the following materials were used: Cleanjoy®, Futurabond DC®, Ionofil Plus® Grandioso®, Grandio® and Profluorid®. As result, it was possible to reach a level of excellence using the indicated materials and specific protocols. Based on this work and the lived experience, it can be observed that these patients can receive welcoming dental care in specialized clinics.

RESUMO Na Odontologia é considerado Paciente com Necessidades Especiais todo usuário que apresenta uma ou mais limitações, temporárias ou permanentes, de ordem mental, física, sensorial, emocional, de crescimento ou médica, que o impeça de ser submetido a uma situação odontológica convencional. Esses pacientes formam um grupo que pode ser considerado de alto risco para o desenvolvimento de doenças bucais, de acordo com o tipo de patogenia. Dentre elas, tem-se a Síndrome de Williams-Beuren, uma desordem congênita rara com envolvimento cardiovascular, retardo mental, face dismórfica, hipercalcemia idiopática, problemas musculoesqueléticos, anomalias dentárias e de crescimento. Os casos são hereditários ou esporádicos e a causa está na concepção com a deleção no braço longo do cromossomo 7. Este artigo relata um caso clínico envolvendo um menino de quatro anos, portador da síndrome, encaminhado para atendimento na Clínica do Curso de Especialização em Pacientes com Necessidades Especiais do Centro de Pesquisas Odontológicas São Leopoldo Mandic, Campinas (SP). Como o paciente apresentava resistência ao atendimento odontológico, com o objetivo de diminuir a ansiedade e aumentar a colaboração, nas sessões de atendimento foi administrado o medicamento Hixizine®. Para o tratamento restaurador atraumático e restaurações estéticas utilizou-se os seguintes materiais: Cleanjoy®, Futurabond DC®, Ionofil Plus®, Grandioso®, Grandio® e Profluorid®. Como resultado, foi possível atingir grau de excelência utilizando os materiais indicados e protocolos específicos. Mediante o caso relatado e frente à experiência vivenciada, pode-se perceber que esses pacientes podem receber um atendimento odontológico acolhedor nas clínicas especializadas.

RESUMO

Abstract: This study aimed to assess the survival of glass ionomer cement (GIC) restorations performed using the atraumatic restorative treatment (ART) in elderly patients. The systematic review protocol was registered in the PROSPERO database. The records were searched until August 2020 in eight electronic bibliographic databases, and included randomized and non-randomized clinical trials and observational studies, with no restrictions on the language or year of publication. Study selection and data extraction were performed independently by two reviewers. Data were extracted, summarized, collected for qualitative analysis, and evaluated for individual risk of bias using the Joanna Briggs Institute's Critical Appraisal Tool. The literature search retrieved 5,186 records; however, only seven studies fulfilled the eligibility criteria and were included. The studies were published between 2002 and 2019. A total of 1,239 restorations were investigated at intervals of 6, 12, 24, and 60 months of follow-up. Some studies had a low risk of bias, while others had moderate and high risk of bias. In general, GIC restorations placed using ART were considered satisfactory. The 6-month, 12-month, and 24-month survival rates ranged from 81.3% to 97.2%, 72.2% to 94%, and 63% to 87%, respectively; additionally, the survival rate for the longest follow-up period (60 months) was 85%. Given the best evidence-based information regarding caries removal, we highlight the need to provide a conservative and effective technique for use in elderly patients. ART is a promising and viable alternative that guarantees the survival of restorations in elderly patients.

RESUMO

INTRODUCTION: Cavitated carious lesions in primary and mixed dentition require prompt treatment to control caries progression. Silver diamine fluoride has emerged as an alternative to the atraumatic restorative technique due to its easy application. However, there is still uncertainty regarding its effectiveness and safety. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a metanalysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified ten systematic reviews, including two studies overall, which are randomized trials. We concluded that silver diamine fluoride compared to the atraumatic restorative technique may increase the arrest of caries in primary and mixed first phase dentition, however, the certainty of the evidence has been assessed as low. On the other hand, treatment with silver diamine fluoride compared to the atraumatic restorative technique (ART) probably increases the risk of adverse events.

INTRODUCCIÓN: Las lesiones de caries cavitadas en dentición primaria y mixta requieren un tratamiento oportuno, para evitar así la progresión de la caries. El fluoruro diamino de plata ha surgido como una alternativa a la técnica de restauración atraumática debido a su fácil aplicación. Sin embargo, aún existe incertidumbre en relación a su efectividad y seguridad. MÉTODOS: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos diez revisiones sistemáticas que en conjunto incluyeron dos estudios primarios, ambos ensayos aleatorizados. Concluimos que el fluoruro diamino de plata en comparación a la técnica de restauración atraumática podría aumentar el arresto de caries en dentición primaria y mixta primera fase, pero la certeza de la evidencia ha sido evaluada como baja. Por otra parte, el tratamiento con fluoruro diamino de plata comparado con la técnica de restauración atraumática (ART) probablemente aumenta el riesgo de eventos adversos.

RESUMO

The aim of this study was to assess the influence of different pre-treatment approaches on glass ionomer cement (GIC) bond strength (BS) to dentine. Sixty bovine incisors were allocated into six groups according to substrate - sound or caries-affected dentine; and substrate pre-treatment approach - no conditioning (control), polyacrylic acid for 10 s and phosphoric acid for 7 s. Teeth in the caries-affected dentine group were previously submitted to cariogenic pH-cycling challenge. After dentine pre-treatment, according to experimental groups, polyethylene tubes were placed on flat dentine surfaces and filled with GIC. Teeth were stored in distilled water for 24 h at 37 °C and then submitted to microshear test (0.5 mm/min). Failure pattern analysis was performed under stereomicroscope (400x). Data were analysed using two-way ANOVA and Tukey's test (α=5%). Statistically significant differences were found for the pre-treatment approach, regardless of substrate (p<0.001). The polyacrylic acid group and control group had similar BS values, and were both better than the phosphoric acid group. In general, GIC had better bonding performance in sound dentine than in caries-affected dentine. In conclusion, dentine pre-treatment with polyacrylic acid did not improve the performance of GIC restoration on clinically relevant substrates.

O objetivo deste estudo foi avaliar a influência de diferentes pré-tratamentos na resistência de união (RU) de cimentos de ionômero de vidro (CIV) a dentina. Sessenta incisivos bovinos foram alocados em 6 grupos de acordo com o substrato ­ hígido ou cariado; e com a abordagem de pré-tratamento ­ sem condicionamento (controle), ácido poliacrílico por 10 s, e ácido fosfórico por 7 s. Os dentes pertencentes aos grupos de dentina cariada foram previamente submetidos ao desafio cariogênico por meio da ciclagem de pH. Após o prétratamento da dentina, de acordo com os grupos experimentais, tubos de polietileno foram colocados sobre superfícies planas de dentina e preenchidos com CIV. Os dentes foram armazenados em água destilada por 24 h a 37°C e então submetidos ao teste de microcisalhamento (0,5 mm/min). A análise do padrão de fratura foi realizada em estereomicroscópio (400x). Os dados obtidos foram analisados usando ANOVA de dois fatores e teste de Tukey (α=5%). Diferença estatisticamente significante foi encontrada para as diferentes abordagens de pré-tratamento, independente do substrato (p<0,001). Aplicação de ácido poliacrílico resultou em valores de RU similares aos do grupo controle. Entretanto, ambos os grupos mostraram um melhor desempenho quando comparado a aplicação de ácido fosfórico. De forma geral, CIV apresentou melho5 desempenho adesivo em dentina sadia quando comparada a dentina cariada. Em conclusão, o pré-tratamento em dentina com ácido poliacrílico não melhora o desempenho das restaurações de CIV em substratos clinicamente relevantes.

RESUMO

BACKGROUND: Dentists need training in the management of children's anxiety (DA), fear (DF) and behaviour management problems (DBMP) but little is known of their competence on this topic. AIM: To report dentists' opinions and attitudes about protective stabilisation and pharmacological techniques for the management of children with DA/DF/DBMP; to propose a postgraduate curriculum focussing on DA/DF/DBMP. DESIGN: A survey of 301 Brazilian dentists and later a modified Delphi process to outline the curriculum in two phases: (a) face-to-face discussions with 33 early career researchers mentored by six researchers, both from UK and Brazil; (b) online discussions by eight early and senior researchers on the knowledge, experience, and competencies necessary for a specialist in paediatric dentistry in Brazil that should be included in the core curriculum of postgraduate courses. RESULTS: Almost all (99.0%) of the survey respondents provide treatment to children with DA/DF/DBMP, and 91.2% do not systematically diagnose these conditions; 94.3% use protective stabilisation, and 20.0%-30.0% have training in pharmacological techniques. The four-domain framework supporting the proposed curriculum is as follows: DA/DF/DBMP assessment, non-pharmacological and pharmacological approaches, and decision-making. CONCLUSION: Dental curricula should be customised to solve the misconceptions and promote a comprehensive and positive attitude to DA/DF/DBMP by paediatric oral healthcare practitioners.

RESUMO

Este estudo objetivou: (1) investigar a eficácia in vitro do diamino fluoreto de prata (DFP) em paralisar lesões de cárie em dentina após diferentes concentrações e tempos de aplicação; (2) comparar o impacto do DFP e do tratamento restaurador atraumático (TRA) na qualidade de vida relacionada à saúde bucal (QVRSB) de préescolares; e (3) avaliar a eficácia do DFP comparado ao TRA, em paralisar lesões de cárie, por meio de um ensaio clínico controlado e randomizado após 2 anos de acompanhamento. Para o objetivo 1, blocos de dentina (n=42) foram fixados em placas de poliestireno. Um inóculo bacteriano misto (1,5x108 UFC/mL) foi adicionado ao meio de cultura com sacarose 5%, contido nas placas, que foram incubadas para a formação de biofilme. As amostras foram escaneadas em micro CT (M1) e tratadas com DFP de acordo com os grupos (n=6): DFP 30%, aplicação imediata; DFP 30%, 1'; DFP 30%, 3'; DFP 38%, aplicação imediata; DFP 38%, 1'; DFP 38%, 3'. Um grupo controle, sem tratamento, também foi preparado. Após o escaneamento (M2), os blocos foram submetidos a um desafio cariogênico (21 dias) e novamente escaneados (M3). O pH do meio de cultura e a profundidade das lesões inter e intra grupos foram comparados pelos testes de Kruskal-Wallis e Wilcoxon. Para os objetivos 2 e 3, préescolares com ao menos uma lesão de cárie ativa na oclusal de seus molares decíduos foram randomicamente alocados em dois grupos: DFP e TRA. Os índicesceo-d/CPO-DICDAS foram usados para detecção da presença e atividade de cárie. O B-ECOHIS foi usado para avaliar a QVRSB antes (M1), 15 dias (M2) e 3 meses (M3) após os tratamentos. O sucesso clínico foi avaliado após 6, 12, 18 e 24 meses. Foram ainda avaliados: tempo do procedimento, efeitos adversos/percepção estética e ansiedade. No estudo in vitro, em M1 e M2, não houve diferença na profundidade das lesões entre os grupos (p>0,05). Em M3, o DFP 38% apresentou menor pH do biofilme e os grupos que receberam aplicação por 1' e 3', em ambas as concentrações, não apresentaram aumento na profundidade da lesão em relação ao M1. DFP e TRA não diferiram quanto ao B-ECOHIS total, CIS e FIS em M2 e M3 e o B-ECOHIS total diminuiu de M1 para M2 e M3 em ambos os grupos (p<0,05). Após 2 anos, não houve diferença entre os tratamentos quanto à paralisação da cárie (p=0,072) e o tempo de tratamento para o DFP foi menor (p<0,001). Não houve diferença entre os grupos quanto aos efeitos adversos/percepção estética observados pelo operador (p=0,816) e pelos pais (p=1,000). A ansiedade não mudou após os tratamentos (p=0,583). Assim, o tempo mínimo de aplicação do DFP 30% para paralisar lesões de cárie foi de 1', enquanto o 38% paralisou com aplicação imediata, in vitro. Tanto o DFP quanto TRA melhoraram a QVRSB dos pré-escolares, sem diferença entre eles. Ainda, o DFP mostrou-se semelhante ao TRA na paralisação de cárie, ansiedade e efeitos adversos, requerendo menor tempo de cadeira. (AU)

This study aimed to: (1) investigate the in vitro efficacy of silver diamine fluoride (SDF) in arresting dentin caries lesions after different concentrations and application times; (2) compare the impact of SDF and atraumatic restorative treatment (ART) on the oral health-related quality of life (QHRQoL) in preschoolers; and (3) to evaluate the effectiveness of SDF compared to ART, in arresting caries lesions, through a controlled randomized clinical trial after 2 years of follow-up. For objective 1, dentin blocks (n=42) were fixed in polystyrene plates. A mixed bacterial inoculum (1.5x108 CFU/mL) was added to the culture medium with 5% sucrose, in the plates; that were incubated for biofilm formation. The samples were scanned on micro CT (M1) and treated with SDF according to the groups (n=6): SDF 30%, immediate application; SDF 30%, 1'; SDF 30%, 3'; SDF 38%, immediate application; SDF 38%, 1'; SDF 38%, 3'. A control group, without treatment, was also prepared. After scanning (M2), the blocks were submitted to a cariogenic challenge (21 days) and scanned again (M3). The pH of the culture medium and the depth of lesions between and within the groups were compared using the Kruskal-Wallis and Wilcoxon tests. For objectives 2 and 3, preschoolers with at least one active caries lesion on the occlusal surface of their primary molars were randomly allocated into two groups: SDF and ART. The indexes dmft/DMFT and ICDAS were used to detect the presence and activity of caries. B-ECOHIS was used to assess the QHRQoL of children before (M1), 15 days (M2) and 3 months (M3) after treatments. Clinical success was assessed after 6, 12, 18 and 24 months. Were also evaluated: time of the procedure, adverse effects/aesthetic perception and the child's anxiety. In the in vitro study, in M1 and M2, there was no difference in the depth of the lesions between the groups (p>0.05). In M3, SDF 38% had a lower pH of the biofilm and the groups that received application for 1' and 3', in both concentrations, did not present an increase in the depth of the lesion in relation to M1. SDF and ART did not differ in total B-ECOHIS, CIS and FIS in M2 and M3; and the total B-ECOHIS decreased from M1 to M2 and M3 for both groups (p<0.05). After 2 years, there was no difference between treatments regarding caries arrest (p=0.072) and the treatment time for SDF was shorter (p<0.001). There was no difference regarding the adverse effects/aesthetic perception observed by the operator (p=0.816) and reported by the parents (p=1.000), according to the groups. Anxiety did not change either before or after treatments (p=0.583). Thus, the minimum time of application of SDF 30% to arrest dentin caries was 1', while SDF 38% arrested with immediate application, in vitro. Both SDF and ART improved the QHRQoL of preschoolers, with no difference between them. Still, SDF was similar to ART in arresting caries, anxiety and adverse effects, requiring less chair time. (AU)

RESUMO

Abstract Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maringá, Brazil. Two main strategies to control caries were considered in the model: the application of fluoride varnish on teeth presenting white spots, and the use of Atraumatic Restorative Treatment (ART) in cavitated carious lesions without pulp involvement. The parameters used in the model were: number of people covered by a local oral health team = 4,000; number of children up to 5 years = 7% of the population; children's decayed, missing, filled teeth (dmft) index = 2.4; time/cost of 4 applications of fluoride varnish = 5 minutes/US$ 0.716; and time/cost of each ART restoration = 15 minutes/US$ 1.475. The SDM generated an estimated total cost of US$698.00, and a total of 112 clinical hours to treat the population in question. The use of the SDM presented here has the potential to assist decision making by measuring the material and human resources required to prevent and control dental caries at an early age.
