RESUMO
BACKGROUND: To assess the prevalence and factors associated with malocclusions in children and adolescents with cerebral palsy (CP). METHODS: The study included 134 subjects with CP aged 2-18 years enrolled in six rehabilitation institutions and their caregivers, which provided demographic, systemic, and behavioral data. A calibrated researcher held oral examinations with record of the following malocclusion indexes, DAI and DMFT. Poisson regression analysis was used (α < 0.05). RESULTS: About 85.8% (n = 115) of patients had malocclusion. In deciduous and mixed dentition (n = 99), increased overjet (75.8%), open bite (51.5%), posterior cross bite (19.2%), and anterior cross bite (3.0%) were identified. Increased overjet was associated with the age group of 2-5 years and mild communication impairment. Anterior open bite was more common in children who underwent tongue interposition, lip interposition, and pacifier sucking. Communication skills, mouth breathing, and tongue interposition were associated with posterior cross bite. Severe malocclusions (DAI > 30) were observed in 88.6% of patients with permanent dentition (n = 35) and were associated with liquid diet consistency and finger sucking. CONCLUSION: The prevalence of malocclusion in individuals with CP was high and associated with demographic, behavioral, and systemic factors.
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.
