RESUMEN

Background: The present in vitro study aimed to evaluate and compare the surface roughness of a colored compomer and a composite resin, after 15 days of erosive-abrasive cycling. Material and Methods: The sample included ninety circular specimens, randomly divided (n = 10): G1 Berry, G2 Gold, G3 Pink, G4 Lemon, G5 Blue, G6 Silver, G7 Orange and G8 Green, referring to the different colors of compomer (Twinky Star®, VOCO, Germany) and G9 for composite resin (Z250®, 3M ESPE). The specimens were submerged in artificial saliva and stored at 37°C for 24 hours. After polishing and finishing, the specimens were submitted to initial roughness (R1). Then, the specimens were submerged in an acidic cola-based drink for 1 minute and then exposed to electric toothbrushing for 2 minutes for 15 days. After this period, the final roughness (R2) and the ΔRa were performed. Data were submitted to ANOVA and Tukey's test for intergroup comparison and paired T-test for intragroup comparison (p<0.05). Results: Among compomers, the green color presented the higher/lower initial and final roughness values (0.94 ± 0.44, 1.35 ± 0.55) with lemon color presenting the most prominent real roughness increase (ΔRa = 0,74) whereas composite resin showed the lower values (0,17 ± 0.06, 0,31 ± 0.15; ΔRa = 0,14). Conclusions: All compomers, after the erosive-abrasive challenge, presented an increase in roughness values when compared to composite resin with a highlight to green tones. Key words:Compomers, composite resins, surface properties.

RESUMEN

Atualmente, diversos materiais restauradores encontram-se disponíveis para aplicabilidade em Odontopediatria. Os avanços dos materiais restauradores conduzem à necessidade de novos estudos nessa temática. O presente estudo apresenta duas propostas de investigação: 1) Estudo transversal com objetivo de avaliar a preferência de pais/responsáveis e crianças quanto ao emprego do compômero colorido (Twinky Star®, Voco, Alemanha); 2) Estudo bibliométrico altimétrico com objetivo de analisar 50 artigos mais citados referente aos materiais restauradores utilizados em Odontopediatria e o alcance dessa informação científica nas mídias on-line. O estudo transversal envolveu 260 pares de pais/responsáveis e crianças de 5 a 11 anos de idade de dois serviços de saúde da região metropolitana de Belo Horizonte-MG. Exame quanto à cárie dentária foi realizado por examinadora calibrada para o critério da Organização Mundial da Saúde. Um manequim odontológico contendo restaurações com compômeros coloridos e materiais convencionais (resina composta, ionômero de vidro e amálgama) foi apresentado aos participantes do estudo e realizou-se inquérito sobre a preferência dos materiais dentários. O Questionário de Estilo e Dimensões dos Pais (PSDQ) e o Eysenck Personality Questionnaire Junior (EPQ-J) foram aplicados, este último apenas para pais/responsáveis de crianças de 5 e 6 anos de idade. Análises descritivas, bivariadas e regressão multivariada de Poisson foram realizadas. A maioria dos pais/responsáveis (74,2%) preferiu materiais convencionais. A idade da criança (p=0,006), a renda familiar (p= 0,001) e o nível de escolaridade (p< 0,001) associaram se a essa escolha. A análise multivariada demonstrou que crianças menores de 7 anos apresentaram 1,20 vezes maior probabilidade de escolher compômeros coloridos do que seus pares mais velhos (p< 0,001), assim como pais/responsáveis com menos de 11 anos de escolaridade e cujos filhos eram menores de 7 anos apresentaram 2,17 e 1,74 maior probabilidade para escolher compômeros coloridos, respectivamente. Concluiu-se que responsáveis com maior escolaridade apresentaram maior resistência às restaurações coloridas e crianças menores de 7 anos aceitaram melhor este material. O estudo bibliométrico-altimétrico adotou estratégia de busca em três bases (Web of Science, Scopus e Google Scholar), independente da data de publicação. Após seleção dos artigos por um grupo de cinco pesquisadores, em março de 2023, foram incluídos estudos que avaliassem qualquer material restaurador empregado em dentes decíduos e analisados dados referentes ao título, número de citações, país/continente, autoria, periódico, instituição, desenho do estudo, tipo de material restaurador, e escore altimétrico. Os artigos, publicados entre 1991 a 2002, apresentaram variação de citações de 19 a 113. Os autores com maior número de citações foram Qvist V e Teglers PT. O estudo experimental foi o principal delineamento de estudo observado e o cimento de ionomero de vidro foi o material mais reportado. A Europa foi o continente, e o Brasil, o país com maior número de citações. O escore altimétrico esteve presente em 23 artigos, com ênfase para dois artigos (43/6º e 73/7º). Concluiu-se que o cimento de ionômero de vidro foi o material mais estudado. Ficou evidente o distanciamento entre a posição dos trabalhos nas análises bibliométrica e altimétrica, apontando necessidade de disseminação da informação além dos círculos acadêmicos.

Currently, an arsenal of restorative materials is available for applicability in pediatric dentistry. The advances in restorative materials conducted to need for further studies in this thematic. The present study presents two investigation proposals: 1) Cross-sectional study aiming to evaluate the preference of parents and children regarding the use of colored compomer (Twinky Star®, Voco, Germany); 2) Bibliometric-altmetric study aiming to analyze the 50-most cited papers regarding to restorative materials used in pediatric dentistry and the dissemination of scientific information in online media. The cross-sectional study included 260 pairs of caregivers/children aged 5 to 11, in two public health services, in the metropolitan region of Belo Horizonte-MG. Examination for dental caries was performed by an examiner calibrated to the criteria of the World Health Organization. A dental mannequin containing colored compomers restorations and conventional materials (composite resin, glass ionomer cement and dental amalgam) was presented to the population and a survey was conducted about the preference of dental materials. Parents' Style and Dimensions Questionnaire (PSDQ) and Eysenck Personality Questionnaire Junior (EPQ-J) were applied, the last one only for parents/caregivers of children aged 5 to 6. Descriptive, bivariate and Poisson regression analyzes were performed. Most adults (74.2%) preferred conventional materials. Family income (p= 0.001) and education level (p< 0.001) were associated with its choice. Age up to 7 (p< 0.001) associated with children's choice for colored restorations (72.3%). Children younger than 7 had 1.20 higher probability to choose colored compomers than their older pairs, while adults with children younger than 7 and less than 11 years of schooling had 1.74 and 2.17 higher probability to choose colored compomers, respectively. It was concluded that caregivers with higher educational level showed greater resistance to use of colored restorations and children younger than 7 had better acceptance of colored material. The bibliometrics-altmetrics study adopted a search strategy in three databases (Web of Science, Scopus and Google Scholar), independent of the year of publication. After selection of papers by a panel of five researchers, in March 2023, any restorative material used in deciduous teeth was included and data about the title, number of citations, country/continent, authorship, journal, design of the study, type of restorative material, university and altmetrics score were analyzed. The papers, published between 1991 and 2002, ranged from 19 to 113 citations. The authors with the highest number of citations were Qvist V and Teglers PT. The experimental study was the main study design observed. Analyzing the continent and country with the highest number of citations, Europe highlighted and Brazil was predominant. The altmetric score was present in 23 papers, emphasizing two articles (43/6th and 73/7th). It was concluded that glass ionomer cement was the most studied material. A gap between the position of the papers correlating the bibliometrics and altmetrics analyzes was evident, demonstrating the need to disseminate the information beyond academic circles.

RESUMEN

Introdução: a inovação dos métodos de fotopolimerização foi proposta na tentativa de diminuir o estresse de contração de polimerização das resinas compostas e proporcionar maior conforto ao paciente, reduzindo o tempo de atendimento odontológico. Objetivo: avaliar a microdureza de duas resinas compostas nanoparticuladas submetidas a diferentes técnicas de polimerização. Material e método: quarenta espécimes foram divididos em quatro grupos (n=10) da seguinte forma: Filtek Z350 XT® + técnica imediata (GI); Filtek One Bulkfill® + técnica imediata (GII); Filtek Z350 XT® + técnica de pulso tardio (GIII); Filtek One Bulkfill® + técnica de pulso tardio (GIV). Após o armazenamento em água destilada à temperatura ambiente, os corpos de prova foram direcionados para a medição de microdureza. Utilizou-se teste T para comparação de técnicas e teste Two-Way ANOVA para calcular os efeitos das resinas compostas, técnicas de polimerização e interações referentes à variável dependente (p ≤0,05). Resultado: a resina Filtek Z350 XT® apresentou maior dureza na técnica imediata (GI - 312,45 ± 64,37) e pulso tardio (GIII - 244,50 ± 75,63) comparado à resina Filtek One Bulkfill®, em ambas as técnicas. Observaram-se maiores valores de dureza referentes à técnica imediata, com diferença estatística significativa em relação à resina testada (p = 0,04 - Filtek Z350 XT®; p = 0,03 - Filtek One Bulkfill®). Ambos os fatores isolados (resina e técnicas) apresentaram efeito nos valores de microdureza (p = 0,02 e p < 0,01, respectivamente). Conclusão: a técnica convencional demonstrou atingir maiores valores de dureza quando comparada à técnica de polimerização alternativa.

Introduction: the innovation of photopolymerization methods was proposed in an attempt to reduce the polymerization shrinkage stress of composite resins and also provide more comfort to patient reducing the chair time. The aim of this in vitro study was to assess the microhardness of two nanofilled composite resins subject to different curing techniques. Objective: assess the microhardness of two nanofilled composite resins subject to different curing techniques. Material and method: forty specimens were divided into four groups (N=10) as follows: Filtek Z350 XT® + immediate technique (GI); Filtek One Bulkfill® + immediate technique (GII); Filtek Z350 XT® + delayed pulse technique (GIII); Filtek One Bulkfill® + delayed pulse technique (GIV). After storage in distilled water at room temperature the specimens were assessed for microhardness measurement. T-test was used for comparison of techniques and two-way ANOVA used to calculate the effects of composite resins, curing techniques and their interactions on dependent variable (p set at 0.05). Result: Filtek Z350 XT® resin presented greater hardness on immediate technique (GI - 312,45 ± 64.37) and delayed pulse (GIII - 244,50 ± 75.63) compared to Filtek One Bulkfill® under both techniques. Overall, it was observed greater hardness values under immediate technique with a significant statistical difference apart of tested resin (p = 0.04 - Filtek Z350 XT®; p = 0.03 - Filtek One Bulkfill®). Both isolated factors (resin and techniques) presented effect on microhardness values (p = 0.02 and p < 0.01, respectively). Conclusion: the conventional technique demonstrated to reach higher hardness values when compared to the alternative polymerization technique

RESUMEN

PURPOSE: Peri-implantitis is an inflammatory disease, characterized by the progressive loss of the peri-implant support bone tissue. The objective of this study was to assess whether implantoplasty is efficacious in promoting peri-implant health. METHODS: In this systematic review and meta-analysis, a search without restrictions regarding language or date of publication was conducted across different databases. Grey literature search, Google Scholar search and manual searches were also carried out. Studies evaluating periimplant clinical parameters of individuals with peri-implantitis who had been submitted to implantoplasty were included. Study selection, data extraction, and risk of bias assessment were conducted. The outcome variables were implant probing depth, the percentage of implants with bleeding on probing or suppuration on probing, and the success rate of implants after implantoplasty. The predictor variable was implantoplasty and the follow-up time after implantoplasty. Data on sample size, implant location, implant diameter, and diagnostic criteria for peri-implantitis were also collected during data extraction. Meta-analysis, sensitivity analysis, and analysis of the probability of implant success after implantoplasty with the Kalan-Meier method were performed. RESULTS: Ninety-four studies were assessed. Eight articles were included and 7 were incorporated into quantitative analyses. Subjects' mean age ranged between 50 to 70.7 years. The studies demonstrated that implantoplasty contributed to a significant improvement in the peri-implant condition, reducing the probing depth, bleeding and suppuration on probing. Overall, the included studies exhibited low risk of bias. Meta-analysis demonstrated that probing depth before implantoplasty was significantly higher than after implantoplasty (mean difference = -3.37 mm, confidence interval = -4.74; -2.00). This result was confirmed in the sensitivity analysis. The probability of success of implants at 6 months of follow-up after implantoplasty was 97.5% and at 24 months of follow-up was 94.7%. CONCLUSIONS: There is some evidence in the literature to recommend implantoplasty as a potential treatment for periimplantitis.

RESUMEN

AIM: To test a chemical-mechanical method and antimicrobial photodynamic therapy (a-PDT) in combination to manage a deep dental carious lesion in a permanent molar pediatric patient. BACKGROUND: Due to specific characteristics of early-erupted teeth, as first permanent lower molars, techniques that provide less invasive tissue removal aiming keep healthy tooth parts, such as pulp tissue, are desired. Furthermore, especially to children, provide comfort, less noise and vibration are important issues that should be considered on the management of deep caries. CASE DESCRIPTION: The following case report presents an association of Papacarie Duo® (PD) and a-PDT used in a 9-year-old patient with a deep dental caries in the mandibular right first molar. After PD application, the carious tissue was carefully removed with the cavity stained for 1 min with rose bengal solution, irradiated with a high intensity LED constituting the a-PDT technique, and definitively restored with composite resin. At 6 months of follow-up, no signs of caries were verified, showing success to applied techniques. A microbiological evaluation attested the antimicrobial effects of the alternative procedures. CONCLUSION: Although it reached optimal clinical and bacterial reduction outcomes, the approach demonstrated an excessive length of time taken for the management of carious lesion. CLINICAL SIGNIFICANCE: The use of new technologies should be encouraged, especially when treating deep caries aiming for a less invasive approach.

RESUMEN

Objetivo: o processo infeccioso e inflamatório decorrente da periodontite poderia contribuir para o desenvolvimento da pneumonia nosocomial. O objetivo deste estudo foi realizar uma revisão da literatura científica sobre a relação entre periodontite e pneumonia nosocomial. Material e métodos: foi realizada uma pesquisa bibliográfica, na base de dados PubMed, por trabalhos que avaliavam o impacto da condição bucal no desenvolvimento da pneumonia nosocomial. Os termos "nosocomial pneumonia" e "periodontitis" foram utilizados nessa busca. Resultados: quatro artigos foram selecionados por dois revisores, para serem incluídos nessa revisão da literatura: um transversal, um do tipo caso-controle, uma revisão sistemática e um ensaio clínico. Conclusão: o número de estudos sobre a associação entre essas duas doenças é extremamente reduzido. O aprimoramento do conhecimento sobre o potencial papel da infecção periodontal na instalação da pneumonia nosocomial é fundamental, pois essa infecção respiratória está associada à significativa morbidade e mortalidade. Estudos adicionais são necessários para elucidação da relação entre essas duas condições patológicas.

Objective: the infectious and inflammatory process in periodontitis could contribute to the development of nosocomial pneumonia. The aim of this study was to review the scientific literature on the relationship between periodontitis and nosocomial pneumonia. Material and methods: a literature search was performed in the PubMed database, for studies that evaluated the impact of oral health in the development of nosocomial pneumonia. The nosocomial pneumonia and periodontitis terms were used in this search. Results: we selected, by two reviewers, four articles to be included in this literature review: a cross-sectional, a case-control, a systematic review and a clinical trial. Conclusion: the number of studies on the association between these two diseases is extremely low. The improvement of knowledge about the potential role of periodontal infection in the nosocomial pneumonia installation is critical because this respiratory infection is associated with significant morbidity and mortality. Additional studies are needed to elucidate the relationship between these two pathological conditions.
