    AbstractThe current study aimed to research the prevalence of temporomandibular disorders (TMD) in patients with subjective tinnitus, as compared to controls, and the association between symptoms of TMD, tinnitus, and chronic pain. Two hundred patients were divided into two groups, according to the presence (experimental) or not (control) of subjective tinnitus. The subgroups were determined according to the RDC/TMD criteria. The Pain Pressure Threshold (PPT) values of the masseter and temporalis muscles were recorded bilaterally, and a Visual Analog Scale (VAS) was used to address subjective pain. The most prevalent TMD subgroups in the tinnitus patients (p < 0.05) were myofascial pain with limited opening (39.0%), disc displacement with reduction (44.33%), and arthralgia (53.54%). The severity of tinnitus was significantly associated with the severity of chronic pain (p = .000). The PPT values were lower (p > 0.05), while the Visual Analog Scale (VAS) was statistically higher (p = .000) for the tinnitus patients. These results suggest that an association exists between TMD and subjective tinnitus.
