Objective:To investigate the effects of occlusal adjustment on temporomandibular disorders (TMD) patients with chronic Orofacial pain.Method:Twenty-one TMD patients with temporomandibular disorders(TMD)chronic orofacial pain, divided randomly into two group, ten in treatment group treated with occlusal adjustment (OA) that aimed to establish a stable occlusal contact condition, and the other eleven in control group with mock occlusal adjustment(MOA).Visual analog scale(VAS), maximum mouth opening and bite force level of the bilateral mandibular first molar teeth were tested or measured before, the moment after occlusal treatment and one month later.Result:In occlusal adjustment treatment group the VAS decreased significantly(P～0.000), maximum mouth opening (P=0.008)and the bite force level increased significantly (P=0.050)one month after the treatment, differed significantly from mock occlusal adjustment group. While no difference was found between that of immediately after treatment and that of before treatment.Conclusion:Occlusal ajustment that aimed to establish a stable occlusal contact condition is effective in alleviating the chronic orofacial pain of TMD patients.
