Asociación de las alteraciones posturales con los trastornos temporomandibulares

Abstract

ObjectiveTo determine the association between postural changes and Temporomandibular Disorders (TMD) in students in the clinics of the Faculty of Stomatology of the Benemeritus Autonomous University of Puebla (FEBUAP) in order to take preventive measures related to postural changes that prevent or reduce the risk of TMD. Material and methodsAn observational, analytic, cross-sectional and unicenter study was performed. The study was based on the evaluation of 129 students from FEBUAP with at least one year of clinical practice. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) proposed by Dworkin and LeResche were used to evaluate the signs and/or symptoms of TMD. Posture was evaluated using the acetate grid. The data obtained in the postural evaluation was focused on the evaluation sheet given by Daniels and Worthingham. Descriptive statistics and statistical association were calculated with the Chi-square test and significance <.05. ResultsA total of 89 (69%) women and 40 (31%) men, with a mean age of 21.6±1.5 years, were included. Evaluation of the posture in their individual items showed no significant differences (P>.050). However, TMD students had higher percentages of moderate posture alterations in the summary of the lateral view (P=.05) and in the overall assessment of posture (P=.051). ConclusionThe results of the association between overall postural assessment and TMD showed that students with TMD presented almost twice the percentage of moderate posture deviation when they were compared with the group without TMD.
