Relação entre disfunções cervicais e desordens no complexo articular temporomandibular

Abstract

Introduction: Temporomandibular disorder (TMD) is a set of functional changes, that affect the masticatory and stomatognathic systems, involving the temporomandibular joint complex and adjacent structures. The prevalence of cervical and temporomandibular dysfunctions has been increasing, negatively impacting quality of life. Objective: To evaluate the presence of symptoms related to temporomandibular joint disorders in individuals diagnosed with cervical dysfunctions. Methodology: This is an observational, descriptive, quantitative and cross-sectional study, composed of 25 individuals with cervical dysfunctions. Data were collected through the application of questionnaires containing personal data, clinical diagnosis, lifestyle habits, and also the Fonseca Anamnestic Index. Data analyzes were performed by descriptive statistics, with mean, standard deviation, absolute frequency and relative frequency. Data crossing was performed using the Chi-square test, with a significance level set at P < 0.05. Results: The prevalence of TMD symptoms was found in 96% of participants, with 36% having mild TMD, 32% having moderate TMD, 28% having severe TMD and 4% having no TMD. Of these results, 68% were female and 32% were male, 40% did not exercise, 16% were smokers and 36% were alcoholics. However, the Chi-square test did not show statistical significance between genders, lifestyle habits and degrees of involvement. Conclusion: The study demonstrated a high prevalence of TMD symptoms in individuals with cervical dysfunctions. The evidence presented serves as a starting point for encouraging new research on the subject, offering insights into epidemiological knowledge. [resumo fornecido pelo autor]
