RESUMO

This study aimed to assess the association between underlying dentin shadows (UDS) and oral health-related quality of life (OHRQoL) among 15-19-year-old adolescents from southern Brazil. This population-based cross-sectional study included a representative sample of 1,197 15-19-year-old adolescents attending 31 public and private schools from Santa Maria, Brazil. The Oral Health Impact Profile-14 (OHIP-14) was used to evaluate the OHRQoL, and clinical examinations were performed by two calibrated examiners (intra/interexaminer kappa values for caries examination ≥ 0.80) to diagnose UDS (ICDAS code 4 caries lesions). Sociodemographic information and clinical characteristics (overall caries experience, traumatic dental injury, malocclusion, and gingivitis) were also collected as adjusting variables. Multilevel Poisson regression models were used to assess the association between UDS and OHRQoL. Rate ratios (RR) and 95% confidence intervals (CI) were estimated. The UDS prevalence was 8.8% (n = 106 adolescents). In the adjusted models, adolescents with UDS had poorer OHRQoL than those without UDS, and the strength of the association was dependent on the number of lesions per individual. Individuals with 1-2 UDS had a mean OHIP-14 score 8% higher (RR = 1.08; 95%CI: 1.01-1.17) than adolescents without UDS, while those with 3-4 UDS had a mean score 35% higher (RR = 1.35; 95%CI: 1.12-1.63). This negative association was related to physical disability, psychological disability, social disability, and handicap domains. This study showed that UDS was associated negatively with OHRQoL among 15-19-year-old adolescents from southern Brazil. The negative effect of UDS on OHRQoL emphasizes the importance of addressing issues regarding OHRQoL even in the posterior teeth of adolescents.

RESUMO

INTRODUCTION: This cross-sectional study assessed the association between sense of coherence (SoC) and caries activity (number of active caries lesions) and caries experience (DMFT index) among 18-19-year-old male adolescents who joined the Brazilian Army as draftees for mandatory military service (n = 507). METHODS: Data collection included a questionnaire (level of education, family income, and tooth brushing frequency), the Brazilian short version of the SoC scale (SOC-13), and clinical caries examination (noncavitated/cavitated, inactive/active). The main predictor variable was SoC, categorized as low, moderate, or high. Poisson regression models were used for statistical analysis. RESULTS: A high SoC was significantly associated with a lower number of active lesions (adjusted rate ratio = 0.85; 95% CI = 0.74-0.98). No association between SoC and DMFT was detected. CONCLUSION: A high SoC was found to be a protective factor to caries activity in this population.

RESUMO

This study aimed to compare the efficacy of 2.5% sodium hypochlorite (NaOCl), 2.5% calcium hypochlorite [Ca(OCl)2], and 2% chlorhexidine (CHX) in the rapid disinfection of gutta-percha cones contaminated with Candida albicans. The minimum inhibitory and minimum fungicidal concentrations of each solution for C. albicans were determined and the ability of each solution to destroy and inhibit biofilm in culture wells was tested. In addition, ninety-eight gutta-percha cones contaminated with the fungal suspension were disinfected according to the type of solution (2.5% NaOCl, 2.5% Ca(OCl)2 or 2% CHX) in its different application methods (without agitation, ultrasonic agitation or agitation with Easy Clean), and regarding the exposure time to each irrigating solution (1 or 5 min). Next, the samples were checked for turbidity and evaluation of viable colonies. The compounds that showed the best performance in biofilm destruction were NaOCl and Ca(OCl)2 at a concentration of 2xMIC (p < 0.001). Regarding inhibited biofilm, the only compound that was effective at all MIC concentrations tested was 2.5% Ca(OCl)2 (p < 0.0001). Regarding the viable colonies, all solutions were effective concerning the control group, for all application methods, in 1 and 5 min (p < 0.05). The densitometer reading showed that CHX was the only effective solution in all application methods performed (p < 0.05). The results demonstrate that all tested solutions were effective in the rapid decontamination of cones contaminated with C. albicans.

RESUMO

Multi-walled carbon nanotubes (MWCNTs) were purified and unpurified in this study to obtain hybrid materials with improved activity. The production stage comprised a chemical purification of the produced sample. Raman spectroscopy analyzed the structural composition of purified and unpurified samples. The disc diffusion assay, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill assessment analyzed antimicrobial activity. MWCNT performed well against the tested bacteria (Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter aerogenes, Staphylococcus aureus, and Streptococcus sp. Staphylococcus epidermidis). The disc diffusion assay revealed inhibition zone differences caused by purified and unpurified MWCNTs. MIC and MBC values of purified and unpurified MWCNTs were similar. The purified and unpurified nanotubes of Staphylococcus epidermidis (ATCC 35985) exhibited inhibition zone diameters of approximately 8 mm and 9 mm, respectively. The microdilution method revealed a MIC of 1.23 mg/ml for the purified nanotube and 0.156 mg/ml for the unpurified nanotube against the same microorganism. The killing curve analysis demonstrated that unpurified carbon nanotubes were more effective against all tested microorganisms. MWCNTs represent a promising method for microbiology, but studies on the toxicity of these materials remain scarce.

RESUMO

OBJECTIVE: The aim of this study was to systematically review observational studies assessing the association between socioeconomic status (SES) and traumatic dental injuries (TDI) in permanent dentition. METHODS: Electronic searches were performed in PubMed, EMBASE, Web of Science, LILACS, CINAHL, COCHANE Library and ScoINDEX databases for articles published up to February 2023. Two independent reviewers performed the search and critical appraisal of the studies. The inclusion criteria were observational studies that evaluated the association between individual-level socioeconomic indicators and TDI (clinically examined) in permanent teeth. Quality assessment of included articles was conducted using the Newcastle-Ottawa Scale. Global meta-analysis was performed with all studies and different subgroup analysis based on socioeconomic indicators (household income, educational level or any other indicator), age (children, early adolescents, late adolescents or young adults) and economic classification of the country (high, upper-middle or lower-middle). A random-effects model was used to estimate pooled prevalence ratios (PR) and respective 95% confidence intervals (CI) for each study. RESULTS: The search strategy retrieved 11 315 publications. According to eligibility criteria, 17 articles were included in the meta-analysis. Individuals with low SES were 17% more likely to have TDI (PR 1.17; 95% CI 1.05-1.30). The subgroup analysis also revealed that the indicator (household income, PR 1.16; 95% CI 1.00-1.34) and the economic classification of the country (upper-middle, PR 1.19; 95% CI 1.07-1.33) influenced the association of SES with TDI occurrence. CONCLUSIONS: Individuals with lower SES were more likely to present with TDI in permanent dentition than those with higher SES.

RESUMO

This study evaluated the association between sense of coherence (SoC) and oral health-related quality of life (OHRQoL) among conscripts of the Brazilian Army, in two cities of southern Brazil. A cross-sectional study included all 18-19-year-old adolescents who joined the Brazilian Army as draftees for mandatory military service in the cities of Itaqui, RS, and Santiago, RS (n = 505). Data collection was conducted from 2019 to 2021, and included the application of questionnaires and a clinical oral examination to record gingivitis, malocclusion, and dental caries. OHRQoL was collected through the Brazilian short version of the Oral Health Impact Profile (OHIP), composed of 14 questions. The adolescents' SoC was assessed using the validated Brazilian version of the SOC-13 scale. The primary outcome of this study was OHRQoL, modeled as a discrete variable (OHIP-14 scores). The main predictor variable was SoC, categorized as low, moderate, or high. The association between predictor variables and OHRQoL was assessed by Poisson regression models using a hierarchical approach. Unadjusted and adjusted rate ratios (RR), and 95% confidence intervals (CI) were estimated. All the analyses were performed using STATA software version 14.2. Adolescents with a moderate and high SoC had 27% (RR = 0.73, 95%CI = 0.64-0.84) and 51% (RR = 0.49, 95%CI = 0.41-0.58) lower mean OHIP-14 scores, respectively, than those with a low SoC score, after the inclusion of behavioral and clinical variables. This study showed a significant association between SoC and OHRQoL among 18-19-year-old southern Brazilian adolescents. Strengthening the SoC as a psychosocial resource may improve the well-being and OHRQoL of adolescents.

RESUMO

The aim of this prospective cohort study was to assess the radiographic progression of underlying dentin shadows (UDS) on the occlusal surfaces of permanent posterior teeth of adolescents and young adults over 1-2 years and to identify possible risk factors. A total of 149 UDS lesions (from 101 individuals) were included at baseline. Each participant had to present at least one UDS to be considered eligible for the study. Data collection included the application of a questionnaire, clinical examination, and bilateral bitewing radiographs, performed at baseline and after 1-2 years. The association between possible predictors and UDS progression (defined radiographically as an increase in the radiographic score from baseline to follow-up) was assessed using Weibull regression models. Hazard ratios (HRs) and their 95% confidence intervals (CIs) were estimated. A total of 81 individuals (mean age: 24.0, standard deviation: 8.03) were reexamined after 1-2 years (742 occlusal surfaces, of which 118 were UDS). The overall progression rate was 8.6% after 1-2 years, being 12.6% for UDS without baseline radiolucency and 20% for UDS with baseline radiolucency. The risk analysis showed that UDS without radiolucency at baseline had a similar likelihood of progression (adjusted HR = 1.71, 95% CI = 0.68-4.32, p = 0.26) while UDS with radiolucency at baseline were more likely to progress (adjusted HR = 2.96, 95% CI = 1.06-8.26, p = 0.04) than the reference category (sound occlusal surfaces without radiolucency). These estimates were adjusted for caries prevalence, tooth type, and arch. This study showed low progression rates of UDS after 1-2 years. The presence of radiolucency at baseline was found to predict UDS progression.

RESUMO

Os traumatismos dentários representam um problema de saúde pública devido à alta prevalência e impacto psicossocial, sendo muito frequentes em crianças podendo resultar em necrose pulpar e culminar na rizogênese incompleta de dentes permanentes. Nestes casos de traumatismos em dentes permanentes com rizogênese incompleta e necrose pulpar, o tratamento mais indicado pela literatura é a apicificação, sendo um tratamento complexo e longo. Considerando a importância deste tema, o objetivo deste trabalho é relatar o caso de um paciente com traumatismo dental e necrose pulpar, que acarretou a interrupção do desenvolvimento completo e adequado do ápice dentário, sendo necessária a intervenção por meio da técnica de apicificação e o acompanhamento a longo prazo. O caso trata-se de uma menina em que um traumatismo dentário acarretou fratura de um incisivo central superior com formação radicular incompleta, comprometendo tanto a estética quanto a vitalidade do dente. Foi realizado o tratamento endodôntico com apicificação e posteriormente ao plug apical de MTA. O dente foi restaurado definitivamente com resina composta e realizado acompanhamento do paciente. Nas consultas de acompanhamento houve ausência de sintomatologia dolorosa e satisfação da paciente com a aparência atual. Sendo assim, a apicificação apresenta-se como uma ótima alternativa para dentes com rizogênese incompleta e necrose pulpar, embora longo houve uma melhora estética e satisfação do paciente.

Dental trauma represents a public health problem due to its high prevalence and psychosocial impact, being very frequent in children and can result in pulp necrosis and culminate in incomplete root formation of permanent teeth. In these cases of trauma to permanent teeth with incomplete root formation and pulp necrosis, the most indicated treatment in the literature is apexification, which is a complex and long treatment. Considering the importance of this topic, the objective of this work is to report the case of a patient with dental trauma and pulp necrosis, which caused the interruption of the complete and adequate development of the dental apex, requiring intervention through the apexification technique and follow-up. long-term. The case is about a girl in which a dental trauma resulted in a fracture of a maxillary central incisor with incomplete root formation, compromising both the esthetics and the vitality of the tooth. Endodontic treatment was performed with apexification and then apical MTA plug. The tooth was definitively restored with composite resin and the patient was followed up. In the follow- up consultations, there was no painful symptomatology and the patient was satisfied with her current appearance. Thus, the apexification presents itself as a great alternative for teeth with incomplete root formation and pulp necrosis, although in the long run there was an aesthetic improvement and patient satisfaction.

RESUMO

As calcificações pulpares provocam alterações morfológicas no interior dos canais radiculares que dificultam o tratamento endodôntico. Para solucionar essa dificuldade, a ferramenta Endoguide ou Endodontia Guiada foi desenvolvida para a resolução de casos complexos. Esta pesquisa objetivou descrever as aplicações da ferramenta Endoguide no tratamento de canais calcificados na endodontia. Todas as buscas foram realizadas por um único pesquisador na base de dados PubMed/MEDLINE e busca manual utilizando os descritores "Endodontics", "Digital", "Cone beam", "Guided". Foram considerados elegíveis os artigos publicados entre 2010 e 2022 e excluídos os estudos cuja publicação não foi obtida na íntegra e ainda aqueles em que os resultados não apresentaram embasamento teórico e prático suficientes para que pudessem ser incluídos no trabalho. Após as buscas, foram encontrados 47 artigos, selecionados inicialmente pelo título e resumos, excluindo as duplicatas. Ao final, a leitura completa e coleta de dados foi realizada em 6 artigos. As informações relevantes dos artigos selecionados foram transcritas em forma de quadro para sumarizar os achados. A endodontia guiada pode ser uma excelente alternativa para tratamentos de casos complexos, necessitando um investimento financeiro mínimo no consultório, pois os equipamentos de captura de imagem, planejamento virtual e de guias podem ser realizados em laboratórios capacitados. Assim, concluímos que o emprego da Endoguide como ferramenta no tratamento de canais calcificados se mostrou bem-sucedido e sua utilização não requer um conhecimento amplo, podendo ser usada por profissionais menos experientes.

Pulp calcifications cause morphological changes inside the root canals that make endodontic treatment difficult. To solve this difficulty, the tool Endoguide or Guided Endodontics was developed to solve complex cases. This research aimed to describe the applications of the Endoguide tool in the treatment of calcified root canals in endodontics. All searches were performed by a single researcher in the PubMed/MEDLINE database and manual search using the descriptors "Endodontics", "Digital", "Cone beam", "Guided". Articles published between 2010 and 2022 were considered eligible, and studies whose publication was not obtained in full text were excluded, as well as those in which the results did not have sufficient theoretical and practical basis for them to be included in the study. After the searches, 47 articles were found, initially selected by title and abstract, excluding duplicates. In the end, the complete reading and data collection was performed with 6 articles. Relevant information from the selected articles was transcribed for a table to summarize the findings. Guided endodontics can be an excellent alternative for treating complex cases, requiring minimal financial investment in the office, as image capture equipment, virtual planning and guides can be performed in trained laboratories. Thus, we conclude that the use of Endoguide as a tool in the treatment of calcified canals proved to be successful and its use does not require extensive knowledge and can be used by less experienced professionals.

RESUMO

Microorganisms such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus are frequently isolated in samples of urinary, blood, intestinal, and respiratory infections, among others. These bacteria are also associated with microbial biofilm formation. E. coli, P. aeruginosa, and S. aureus biofilm infections are particularly hard to manage and often associated with nosocomial problems. This study investigated the influence of different culture media on E. coli, P. aeruginosa, and S. aureus biofilm formation. Bacterial performance was evaluated in brain heart infusion broth, Mueller-Hinton broth, or tryptic soy broth, with or without supplementing with different glucose levels (1-5%). The study quantified biofilm biomass and the count of viable biofilm colonies. This is the first study that compares the biofilm formation of E. coli, P. aeruginosa and S. aureus in polystyrene using different culture media and with different glucose concentrations. The most robust growth of E. coli, P. aeruginosa, and S. aureus occurred in brain heart infusion broth supplemented with 5% glucose, Mueller-Hinton broth without glucose, and tryptic soy broth with 2% glucose, respectively. Our data demonstrate that behavioral and morphological characteristics of each bacterium require a specific broth to enhance the growth of these microorganisms. These findings will contribute to future tests for therapeutic alternatives with anti-biofilm potential.

RESUMO

Background and Objective: This study aimed to assess the prevalence, extent, risk indicators, and intraoral distribution of underlying dentin shadows (UDS) in the occlusal surfaces of the permanent posterior teeth. Subjects and Methods: A total of 1197 adolescents were included in the study (participation rate of 72.3%). The association between the independent variables, on the one hand, and the prevalence and extent of UDS were assessed using multilevel Poisson regression models. The prevalence ratios (PR), rate ratios (RR), and 95% confidence intervals (95% CIs) were estimated. The overall prevalence of UDS was 8.8% (95% CI = 6.0-11.5), with an overall mean of 0.13 (95% CI = 0.08-0.17) lesions per individual. Those with UDS exhibited a mean of 1.45 (95% CI = 1.28-1.62) lesions. Results: Lower family income (PR = 1.58; 95% CI = 1.03-2.41) and caries activity (PR = 1.53; 95% CI = 1.01-2.31) were significantly associated with UDS prevalence, while age ≥17 years (RR = 1.43; 95% CI = 1.03-1.99) and caries activity (RR = 1.63; 95% CI = 1.55-2.30) were significantly associated with caries extent. The most commonly affected teeth were lower first molars, followed by upper first molars and lower second molars. Conclusion: This study found a low prevalence and extent of UDS in the occlusal surface. Sociodemographic variables and caries activity were associated with the occurrence of UDS.

RESUMO

This study aimed to assess the prevalence, extent, and associated factors of underlying dentin shadows (UDS) in the occlusal surfaces of permanent posterior teeth among 12-year-old schoolchildren from southern Brazil. A population-based cross-sectional study that included a representative sample of 1,528 schoolchildren was conducted in Porto Alegre, southern Brazil (participation rate: 83.2%). A questionnaire on sociodemographic characteristics, behavioral habits, and access to dental services was sent to parents/legal guardians of each student selected. Caries examination included the recording of non-cavitated and cavitated lesions, including the presence of UDS, as defined by the ICDAS Group (i.e., a shadow of discolored dentin visible through an apparently intact enamel surface that may or may not show signs of localized breakdown - ICDAS Code 4). The association between predictor variables and UDS prevalence was assessed using survey Poisson regression models. The prevalence of UDS was 6.3% (95%CI = 1.2 -11.3). The mean number of affected teeth among the schoolchildren presenting UDS was 1.51 (95%CI = 1.40 -1.61), ranging from 1 to 6. Type of school (public, PR = 2.23, 95%CI = 1.22 -4.07) and caries experience (DMFT 1-2, PR = 2.41, 95%CI = 1.15 -5.04; DMFT ≥ 3, PR = 3.09, 95%CI = 1.52 -6.27) were significantly associated with UDS prevalence. In conclusion, this population-based cross-sectional study found a low prevalence of UDS in the occlusal surfaces of the permanent posterior teeth of 12-year-old southern Brazilian schoolchildren. Overall caries experience and type of school were associated with UDS in this population.

RESUMO

Objetivo: analisar informações presentes na literatura sobre a citada patologia com enfoque odontológico, baseando-se em evidências atuais, a fim de estruturar uma conduta clínica, métodos preventivos e terapêuticos. Revisão de literatura: executou-se busca na literatura em dezembro de 2020, por meio dos descritores pré-estabelecidos, nos bancos de dados LILACS e PubMed/MEDLINE, além de complementações utilizando o Google Scholar. Foram encontrados 563 artigos, refinados em 10, juntamente ao uso de 3 livros. Considerações finais: a partir dos achados, constatou-se que a realização de uma anamnese criteriosa durante a primeira consulta faz-se imprescindível, por auxiliar na compreensão dos aspectos fisiopatológicos do paciente, os quais irão determinar o emprego ou não de fármacos, principalmente antes de procedimentos invasivos. Em contrapartida, verificou-se a negligência desse assunto no âmbito odontológico, pelo fato de existirem poucos estudos relacionados ao manejo clínico de pacientes com Febre Reumática (FR), sendo necessárias maiores pesquisas, com o fito de construir-se uma conduta clínica adequada, reduzindo-se os riscos e a incidência de tal enfermidade.(AU)

Objective: to analyze information in the literature about mentioned pathology with a dental focus, based on current evidence in order to structure a clinical conduct, preventive and therapeutic methods. Literature Review: literature searches were performed in December 2020, using pre-established descriptors, in the databases LILACS and PubMed/MEDLINE, in addition to complementations using Google Scholar. About 563 articles were found, refined in 10, along with the use of 3 books. Final Considerations: From the findings, it was found that the performance of a careful anamnesis during the first consultation is essential, as it helps to understand the patient's pathophysiological aspects, which will determine the use of drugs, mainly, before invasive procedures. On the other hand, this matter was neglected in the Dental field, due to the fact that there are few studies related to the clinical management of patients with Rheumatic Fever (RF), and further research is necessary, with the aim of building an adequate clinical conduct, reducing the risks and the incidence of such a disease.(AU)

Literature Review: A literature search was performed in the Lilacs, SciELO and PubMed/ Medline databases, using terms related to the theme, without time restriction and adapted for each base. The searches were carried out by a single examiner from September to November 2019. After a critical reading of the 21 selected articles, it appears that there are several studies with many designs that evaluated the predictability measured in various ways. Final considerations: In view of the scientific evidence found, the rehabilitation of edentulous jaws with the all-on-four technique proves to be predictable and stable. Retrospective, prospective studies and systematic reviews report high success rates, low marginal bone loss, basing the use of the all-on-four technique in dentistry.(AU)

RESUMO

Religiosity has been associated with a better dental condition and positive self-perception of health, but there are no studies on the relationship between religious practice and oral health-related quality of life (OHRQoL), especially among schoolchildren. Thus, the aim of this study was to evaluate the association between family religiosity and OHRQoL in 12-year-old schoolchildren. We conducted a cross-sectional study in a representative sample of 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. A total of 1,134 schoolchildren were assessed in a randomly selected in 20 public schools in the city. Participants were examined by 4 calibrated dentists (minimum Kappa-value for intra and inter-examiner agreement were 0.79 and 0.77, respectively) according to dental caries (Decayed, Missed, Filled Teeth Index), and gingival bleeding (Community Periodontal Index criteria). OHRQoL was assessed by the Brazilian short version of Child Perceptions for Questionnaire (CPQ11-14). Parents or guardians answered a structured questionnaire regarding their socioeconomic status and religious practice. Data were analyzed using multilevel Poisson regression analysis to assess the association of religiosity and overall and domain-specific CPQ 11-14 scores. Religious practice less than once a week was associated with higher mean symptoms domain scores and higher mean CPQ 11-14 overall scores in schoolchildren. In conclusion, our findings demonstrate that family religiosity was positively associated with schoolchildren's OHRQoL.

Resumo A religiosidade tem sido associada a uma melhor condição dentária e autopercepção positiva de saúde, mas não há estudos sobre a relação entre a prática religiosa e qualidade de vida relacionada à saúde bucal (QVRSB), especialmente entre escolares. Assim, o objetivo deste estudo foi avaliar a associação entre religiosidade da família e a QVRSB em escolares de 12 anos de idade. Nós realizamos um estudo transversal em uma amostra representativa de escolares de 12 anos de idade de Santa Maria, uma cidade no sul do Brasil. Um total de 1.134 escolares foram avaliados em uma seleção aleatória em 20 escolas públicas da cidade. Os participantes foram examinados por 4 dentistas calibrados (valor mínimo do Kappa para concordância intra e inter-examinador foi de 0,79 e 0,77, respectivamente) de acordo com cárie dental (Índice de Dentes Cariados, Perdidos e Obturados) e sangramento gengival (Índice Periodontal Comunitário). QVRSB foi avaliada pela versão reduzida brasileira do Child Perceptions for Questionnaire (CPQ11-14). Os pais ou responsáveis responderam a um questionário estruturado sobre sua condição socioeconômica e prática religiosa. Os dados foram analisados usando análise de regressão de Poisson multinível para avaliar a associação de religiosidade e escores de QVRSB geral e por domínio específico. A prática religiosa menos de uma vez por semana foi associada com maior escore do domínio sintomas orais e maior média do escore total do CPQ 11-14 em escolares. Em conclusão, nossos achados demonstram que religiosidade familiar foi positivamente associada com a QVRSB dos escolares.
