ABSTRACT Purpose To investigate the influence of the presence of Temporomandibular Disorders (TMD) on postural balance in elderly individuals. Methods The study sample consisted of 150 elderly: 103 women (67.7±5.0 years) and 47 men (69.3±5.5 years). Evaluation of the presence and severity of TMD included an anamnesis questionnaire, an evaluation of the temporomandibular joint (TMJ), and a muscular examination, which allowed the division of the elderly into 2 groups: G1 (experimental, n=95), with TMD; G2 (control, n=55), without TMD. Postural balance was assessed by means of the one-leg stance test (OLST) on a force platform (BIOMEC400), thus permitting the following measurements: center of foot pressure (COP); mean sway velocity (MV) and frequency (MF) of COP in both the anteroposterior (VAP and FAP) and medial/lateral (VML and FML) directions. The statistical analysis of data was performed using independent t-test, Variance Analysis, and Chi Square test (α=5%). Results Presence of TMD was observed in 63.3% of the individuals (Group 2), with different degrees of severity (mild: 42.7%, moderate: 14.7%, severe: 6%). Significantly higher TMD was observed for women (73.8%) compared with men (40.4%) (p=0.0002). No significant difference was found in between the groups for all balance parameters, e.g., presence and severity of TMD, presence of pain to palpation of TMJ and of masticatory and cervical muscles. Conclusion The presence and severity of TMD, in addition to the presence of pain to palpation of TMJ and masticatory and cervical muscles did not alter the variables related to postural balance in this population.
