RESUMO
AIM: To assess the impact of incisor molar hypomineralization (MIH) on oral health-related quality of life (OHRQoL) according to the perception of students and their parents/caregivers. MATERIALS AND METHODS: This is a cross-sectional population-based study with 463 Brazilian students aged 11-14 years. OHRQoL was measured using the Child Perceptions Questionnaire (B-CPQ11-14ISF: 16) applied to students and the short version of the Parental-Caregiver Perceptions Questionnaire (B-P-CPQ) applied to parents/caregivers. The diagnosis of MIH followed the European Academy of Paediatric Dentistry criteria modified in 2019. Caries experience (ICDAS II), malocclusion (DAI), and socioeconomic and demographic factors were assessed as confounding factors for impact on OHRQoL. Cluster analysis was carried out to dichotomize the negative impact into greater and lesser impact. The chi-square test and Poisson regression were performed (p < 0.05) to verify associations between quality of life and MIH, adjusted for confounding variables. RESULTS: The prevalence of MIH was 10.8%. Multivariate regression demonstrated that caries experience was the only oral disease that impacted OHRQoL according to students' self-perception in the functional limitation domain (PR = 1.82; 95% CI = 1.20-2.77) and in the total questionnaire score (PR = 1.59; 95% CI = 1.00-2.51). However, according to the perception of parents/caregivers, in addition to caries experience, which affected OHRQoL in the oral symptoms (PR = 3.57; 95% CI = 1.71-7.414) and emotional well-being domains (PR = 1.71; 95% CI = 1.08-2.69), as well as in the total B-P-CPQ score (PR = 1.67; 95% CI = 1.01-2.76), malocclusion also affected OHRQoL in the social well-being domain (PR = 1.50; 95% CI = 1.07-2.10) and in the total questionnaire score (PR = 1.54; 95% CI = 1.11-2.15). CONCLUSION: According to students and their parents/caregivers' perception, incisor molar hypomineralization did not influence OHRQoL of the studied sample.
RESUMO
AIM. medical problems specifically affecting professional musicians are commonly mentioned in the literature. the present study is aimed to evaluate, through a systematic review, the possible association between the practice of string with bow and wind musical instruments and the occurrence of temporomandibular dysfunction (TMD). METHODS. the search for articles was conducted in PubMed/ Medline, Web of Science, Scopus, Lilacs, Cochrane Library, and Open Gray databases, and there was no restriction on language or date of publication. the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. the MeSH terms used were: "music"; "temporomandibular joint"; "temporomandibular joint disorders"; "temporomandibular joint dysfunction syndrome"; and "occupational diseases". cross-sectional studies, case-control, cohort and clinical trials were included that involved the practice of string with bow and wind musical instruments and the occurrence of temporomandibular dysfunction (TMD). articles were previously selected by title and abstract. qualitative evaluation was done through the Newcastle-Ottawa scale. RESULTS. the literature search identified 732 studies, of which 10 met the inclusion criteria, nine of them cross-sectional studies and one a clinical intervention study. the TMD prevalence ranged from 47.0 percent to 89.0 percent. recruitment of participants took place in professional schools and orchestras, and in bands of professional musicians. all studies reported associations between TMD and the practice of musical instruments, and violinists presented higher prevalence rates when compared to other instrument groups. CONCLUSION. all studies pointed to a possible association between TMD and the practice of string and wind musical instruments. more longitudinal and clinical trials studies are needed to verify any possible interrelationship.
