Resumen Caries relacionada a radiación es una complicación tardía frecuente de la radioterapia de cáncer de cabeza y cuello, ocasionada por efectos directos e indirectos de la radioterapia. El objetivo del presente trabajo es realizar una revisión y analizar literatura sobre el manejo de caries relacionada a radiación, materiales usados, fallas en el tratamiento y protocolo con mejores resultados; tres revisores independientes realizaron una búsqueda en diferentes bases de datos: PubMed, Lilacs y Web Of Science, determinando criterios de inclusión y exclusión para la selección. Estudios clínicos y revisiones indicaron que los materiales más usados son cemento ionómero de vidrio convencional, cemento ionómero de vidrio modificado con resina y resina compuesta con aplicaciones de flúor. Son necesarios más estudios para definir el mejor tratamiento que incluya técnica de preparación de la cavidad y material restaurador con mejores resultados. Se recomienda realizar estudios comparando diferentes sistemas adhesivos, concentraciones de flúor y restauraciones en dentina radicular.

Abstract Radiation-related caries are a frequent late complication caused by the direct and indirect effects of head and neck cancer radiotherapy. This study aimed to review and analyze the literature on managing radiation-related caries, restorative materials, treatment failures, and treatment protocols. A search was conducted in Pubmed, Lilacs, and Web of Science by three independent reviewers, and inclusion and exclusion criteria were used for paper selection. According to clinical studies and literature reviews, the most used materials are conventional glass-ionomer cement, resin-modified glass-ionomer cement, and composite resin with fluoride applications. More studies are needed to determine the best treatment, including cavity preparation technique and restorative material with better results. We suggest conducting studies comparing various adhesive systems, fluoride concentrations, and root dentin restorations.

Resumo Cárie relacionada à radiação é uma complicação tardia frequente da radioterapia de câncer de cabeça e pescoço, ocasionada por efeitos diretos e indiretos da radioterapia. O objetivo do presente trabalho é realizar uma revisão e analisar literatura sobre o tratamento de cárie relacionada à radiação, materiais usados, falhas no tratamento e manejo com melhores resultados; foi realizada uma busca em diferentes bases de dados: PubMed, Lilacs e Web Of Science, por três revisores independentes, usando critérios de inclusão e exclusão. Estudos clínicos e revisões de literatura indicam que os materiais mais usados são cimento de ionômero de vidro convencional, cimento de ionômero de vidro modificado com resina e resina composta com aplicações de flúor. Mais estudos são necessários para definir o melhor tratamento que inclua a técnica de preparo cavitário e material restaurador com melhores resultados. Recomenda-se a realização de estudos comparando diferentes sistemas adesivos, concentrações de flúor e restaurações em dentina radicular.

Abstract Temporomandibular dysfunction (TMD), anxiety, and depression are disorders that, due to the current lifestyle, are affecting an increasing portion of the population. Investigating the prevalence of the symptoms of these disorders during the quarantine due to the coronavirus 2019 pandemic (COVID-19) is important to outline clinical strategies for patient care. Objective: This study assessed the prevalence of TMD symptoms, anxiety, depression, and oral behaviors and their associations during the social isolation due to COVID-19. Methodology: Questionnaires were used to assess TMD symptoms in accordance with the Diagnostic Criteria for Temporomandibular Disorders: clinical protocol and assessment instruments, a questionnaire to verify oral behaviors and Hospital Anxiety and Depression Scale to assess symptoms of anxiety and depression in students of dentistry at the Faculty of Health Sciences of the University of Brasília in May 2020. Qualitative data were subjected to descriptive statistics and chi-squared analysis (p<0.05). The relationship between quantitative and qualitative data was evaluated using Spearman's rho correlation (p<0.05). Results: There was a high prevalence of TMD symptoms, anxiety, and depression in the participants, resulting in association between gender and anxiety symptoms (p=0.029). There was a positive correlation between oral behaviors and TMD symptoms (r=0.364; p<0.001), between oral behaviors and anxiety symptoms (r=0.312; p=0.001), and between oral behaviors and symptoms of depression (r=0.216; p=0.021). Conclusion: Social isolation due to the COVID-19 pandemic has an impact on the prevalence of TMD symptoms, anxiety, and depression.
