A systematic review assessing occurrence of medication-related osteonecrosis of the jaw following dental procedures

Aim: This study aimed to systematically review existing literature regarding the association between dental procedures­such as tooth extractions and periodontal therapy­and occurrence of medication-related osteonecrosis of the jaw (MRONJ) in individuals using bone-modifying drugs. Methods: Search strategies were performed in PubMed, Scopus, Web of Science and Cochrane Library for a timeframe ending in December 2021. Study selection, data extraction and risk of bias were analyzed independently by two researchers. Three meta-analyses were performed, estimating the crude risk ratio (RR), the adjusted odds ratio (OR) and the adjusted hazard ratio (HR) for the association between tooth extraction and MRONJ. Results: Of the 1,654 studies initially retrieved, 17 were ultimately included. The majority of patients with MRONJ in these studies were female, with a mean age of 64 years. Zoledronic acid was the most commonly used drug among patients with MRONJ, and cancer was the most frequent underlying health condition. Regarding the performed meta-analyses, crude and adjusted analyses demonstrated that tooth extraction increased the risk for MRONJ by 4.28 (95% confidence interval [95%CI]: 1.73­10.58), the OR for MRONJ by 26.94 (95%CI: 4.17­174.17), and the HR for MRONJ by 9.96 (95%CI: 4.04­24.55). Conclusion: It was concluded that performing dental procedures, especially tooth extraction, in patients using bone-modifying drugs increased the risk of MRONJ occurrence and, therefore, should be avoided. Further studies, using adjusted data, are warranted

Prevalence of temporomandibular disorder and possible associated factors in a sample of older adults: population-based cross-sectional study / Prevalência de disfunção temporomandibular e possíveis fatores associados em uma população de idosos: estudo transversal de base populacional

ABSTRACT BACKGROUND AND OBJECTIVES: Temporomandibular disorders (TMD) are a group of conditions characterized by changes in the movements and function of the orofacial region and one of main reported symptoms is pain. As it has been increasingly described among different age groups, this study aimed to evaluate the presence of symptoms of TMD and their possible associated factors in older people from a city in southern Brazil. METHODS: A cross-sectional household-based study using a per cluster sampling strategy was performed including 282 older adults aged ≥60 years in the city of Veranópolis/RS. A clinical oral examination and a structured questionnaire were applied. TMD symptoms were evaluated with Fonseca Anamnestic Index (FAI) questionnaire and divided into those "without TMD" and "with TMD" (the later including those reporting mild, moderate and severe TMD symptoms). Associations were performed by the chi-square or Mann-Whitney tests based on frequency distribution. Bi and multivariate analyses were performed using Poisson regression with robust variation to verify associations. RESULTS: Prevalence among older adults that reported symptoms of TMD was 30.5% (n=86). In the final multivariate model, female older adults presented higher prevalence ratio (PR) for symptoms of TMD, presenting 62.8% (p=0.040) higher PR to at least mild symptoms of TMD when compared to older adult men. Number of teeth, need for dental prosthesis or other demographic variables were not associated with symptoms of TMD. CONCLUSION: The results demonstrated a prevalence of TMD symptoms in the seniors of approximately 30%, which was most associated with females. Despite its relevance in public health strategies focused on older adults, these findings should be interpreted with caution due to their observational and cross-sectional nature.

RESUMO JUSTIFICATIVA E OBJETIVOS: As disfunções temporomandibulares (DTM) são um grupo de condições caracterizadas por alteração dos movimentos e função da região orofacial e um dos maiores sintomas relatados é a dor. Como estas disfunções têm sido descritas de forma crescente entre diversas faixas etárias, o objetivo deste estudo foi avaliar a presença de sintomas de DTM e seus possíveis fatores associados em idosos de uma cidade do sul do Brasil. MÉTODOS: Estudo transversal de base domiciliar com amostra probabilística por conglomerado incluindo 282 idosos com idade ≥60 anos da cidade de Veranópolis/RS. Um exame clínico de saúde bucal e questionário estruturado foram aplicados. Sintomas de DTM foram avaliados pelo Índice Anamnésico de Fonseca (IAF) e categorizados em "Sem DTM" e "Com DTM", sendo que o último incluiu aqueles com sintomas compatíveis com DTM, moderada ou grave. Associações foram avaliadas pelos testes de Qui-quadrado ou Mann-Whitney por distribuição de frequências. Análises bi e multivariadas foram realizadas utilizando-se regressão de Poisson com variância robusta para verificar associações. RESULTADOS: A prevalência de idosos que relataram sintomas de DTM foi de 30,5% (n=86). No modelo multivariado final, idosas do sexo feminino apresentaram maior razão de prevalência (RP) para sintomas de DTM, apresentando 62,8% maior RP (p=0,040) de ter, pelo menos, sintomas leves de DTM quando comparados a idosos do sexo masculino. O número de dentes presentes, necessidade de prótese ou outras variáveis demográficas não estiveram associadas com a presença de sintomas de DTM. CONCLUSÃO: Os achados do presente estudo demonstraram prevalência de sintomas de DTM em idosos de aproximadamente 30%, com maior associação com o sexo feminino. Apesar de relevantes para delineamento de estratégias de saúde para idosos, os achados do presente estudo devem ser interpretados com cautela por sua natureza observacional e transversal.
