Aim Temporomandibular joint disorders (TMD) are complex disorders aff ecting the temporomandibu-lar joint (TMJ), masticatory muscles and related structures, o/f_t en causing severe pain and functional limitations. /T_h is study aimed to compare clinical /f_i ndings among three TMD subtypes (osteoarthritis [OA], disc displacement with reduction [DDWR], and disc displacement without reduction [DDWoR]) and bruxism, and to evaluate the prevalence and characteristics of tinnitus in these groups. Materials and MethodsA retrospective cross-sectional study was conducted on 97 patients with primary diagnoses of OA, DDWR, DDWoR or Bruxism. Clinical parameters evaluated included impairment in daily activities, masticatory pain and effi ciency, joint sounds, muscle palpation scores, maximal mouth opening and presence of tinnitus. Data were statistically analyzed by accepting the signi/f_i cance level as p<0.05. Results DDWoR patients showed the highest levels of impairment in daily activities, chewing pain, and decreased maximal mouth opening. Bruxism patients had the highest masseter palpation scores and tinnitus prevalence. Joint sounds were most prominent in the DDWR group. OA patients exhibited intermediate scores, higher than those of the DDWoR and bruxism groups, but signi/f_i cantly lower than those of the DDWR group. No signi/f_i cant diff erence was found between the groups in temporal palpation scores. Conclusions /T_h /i.dots study evaluates the eff ects of d/i.dotff erent TMD subtypes and brux/i.dotsm on cl/i.dotn/i.dotcal f/i.dotnd/i.dotngs, reveal/i.dotng the un/i.dotque symptom prof/i.dotles and common features of these d/i.dotseases. /T_h e f/i.dotnd/i.dotngs emphasi/dotze the /i.dotmportance of /i.dotnd/i.dotv/i.dotdual/i.dotzed approaches /i.dotn TMD d/i.dotagnos/i.dots and treatment processes.
