RESUMO
OBJECTIVES: To evaluate noncarious cervical lesions (NCCL) in older adults by analyzing each lesion's morphology, dimension, and occlusal risk factors using intraoral scanning and clinical evaluation. MATERIALS AND METHODS: Individuals over 60 treated at the School of Dentistry in Minas Gerais, Brazil, were invited to participate in this cross-sectional study. We clinically evaluated 1245 teeth for the presence of NCCL and dentin hypersensitivity (DH) in 53 individuals. Three-dimensional models were obtained using Omnicam, and occlusal risk factors were evaluated through the presence of wear facets, intense occlusal contacts, and interferences. The 3Shape 3DViewer software was used to classify NCCL morphology and to measure their height. NCCL depth, width, and area measurements were determined using ImageJ. Descriptive analyses were performed. The Kolmogorov-Smirnov test showed that quantitative data exhibited non-normal distribution. For bivariate analyses of quantitative data, the Mann-Whitney test was employed. The results were reported with mean, standard deviation, median, minimum, and maximum. For bivariate analyses of categorical data, the Pearson chi-square test was used. The results were reported with frequencies (counts) and percentages. A regression model evaluating the association between occlusal risk factors and the absence/presence of NCCL was built. RESULTS: Most participants were female (58.5%), with a mean age of 66. The frequency of NCCL was 28.27%, corresponding to 352 teeth. Of these, 68.18% exhibited saucer morphology and 31.82% wedge-shaped morphology. The frequency of DH was 13.92% in teeth with NCCL. Saucer NCCL exhibited significantly greater height (p = 0.02), while wedge-shaped lesions showed greater depth (p < 0.001). Also, teeth with NCCL had a higher proportion of wear facets (66.8%; p < 0.001), intense occlusal contacts (39.8%; p = 0.008), and occlusal interferences (21.9%; p = 0.05). The regression model showed that teeth with wear facets were 1.50 times more likely to exhibit NCCL than teeth without wear facets (p < 0.001). Teeth with intense occlusal contact were 1.22 times more likely to exhibit NCCL than teeth without intense occlusal contact (p = 0.031). CONCLUSIONS: NCCL is a common dental condition in the older adults evaluated in this study. Wedge-shaped NCCL exhibited greater depth, while saucer NCCL had more expressive height. Occlusal risk factors may represent a crucial mechanism for the occurrence of NCCL in this population. CLINICAL RELEVANCE: Understanding the mechanisms involved in developing NCCL is helpful in diagnostic and preventive practices. The study showed the importance of dental occlusion and characteristics of different NCCL morphologies that help the clinician in decision-making.
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.
Aim: This scoping review aimed to compare the success rate of restorations using five different brands of High Viscosity Glass Ionomer Cement (HVGIC), reference material in Atraumatic Restorative Treatment (ART). Methods: Searches were carried out in PubMed, Scopus, and Web of Science. OpenGrey and Google Scholar searches were also performed. Inclusion criteria were studies (clinical trials and follow-up studies) that evaluated the success of restorations using HVGIC. Title, abstract, and full text of the references were evaluated by two authors. Articles that met the inclusion criteria were included. Data extraction was performed. Cox regression models were created to compare the success rate of restorations produced with different types of HVGIC. The results were reported as odds ratio (OR) and confidence intervals (CI). Kaplan Meyer analyses were performed to calculate the HVGIC restorations' probability of success.Results: Nine articles evaluating ChemFil Rock, ChemFlex, Equia Fil, Ketac Molar, or Fuji IX were included. Restorations with glass ionomer cements Fuji IX (OR = 3.51; CI = 1.96 - 6.28), Ketac Molar (OR = 4.01; CI = 2.40-6.68), and ChemFlex (OR = 4.20; CI = 1.01-17.66) had a significantly higher success rate than those with ChemFil Rock. EquiaFil achieved the second lowest efficacy, slightly higher than ChemFil Rock.Conclusion: Restorations with Fuji IX, Ketac Molar, and ChemFlex showed high success rates over the ART evaluation time.
