| Abstract | |
The aim of this study was to study the prevalence of Temporomandibular Disorders (TMD) subgroups and oral parafunctional habits, daytime clenching and sleep bruxism, in patients with subjective tinnitus when compared to a group of asymptomatic volunteers. Two hundred patients (ages between 18-60 years-old) participated in this study, divided into two groups, according to the presence (experimental) or not (comparison) of subjective tinnitus. According to the RDC/TMD criteria, the subgroups were determined. The Pain Pressure Threshold (PPT) values of masseter and temporalis (anterior, middle, and posterior regions) muscles were recorded bilaterally with an algometer and a visual analog scale (VAS) was used to address subjective pain. The severity of the TMD was determined by using an anamnestic questionnaire while a self-reported questionnaire detected parafuncional habits. Data were submitted to statistical analysis (Chi-square, t Student, Mann-Whitney and Spearmans Correlation), at a 5% significance level. The prevalence of signs and symptoms of TMD was significantly associated with the presence of tinnitus (p.001). The three most prevalent TMD subgroups in tinnitus patients (p<.05) were myofascial pain with temporomandibular joint (TMJ) internal derangement (39%), disc displacement with reduction (44,33%) and arthralgy (53,54%). The PPT values were lower (p>.05) while VAS was statistically higher (p<.05) for tinnitus patients. The severity of TMD was associated with tinnitus (p0.001). Both, the report of sleep bruxism (58%), as well as of daytime clenching (60%) were found more frequently in tinnitus patients. Significant difference, however, was detected only for the report of bruxism (p<.05). These results suggest that an association exists between TMD and subjective tinnitus. (AU) | |
