The purpose of the present study was to compare differences in age, sex, temporomandibular joint（TMJ）noise, presence of trismus and pain intensity in temporomandibular joint disorders（TMD）patients between in 2007 and in 2022. This study included 1,417 TMD patients who sought treatment for orofacial pain at the Orofacial and Head Pain Clinic in either 2007（n=762）or 2022（n=655）. For all TMD patients, age, sex, presence of TMJ noise, presence of trismus, the present pain intensity when the patient first visited the clinic and the worst pain intensity during past 6 months were recorded. The mean age of TMD patients was significantly higher in 2022 than in 2007. There was no significant difference in female-to-male ratio between in 2007 and in 2022. The proportion of patients with TMJ noise was significantly higher in 2007 than in 2022. There was no significant difference in trismus ratio between in 2007 and in 2022. The present pain intensity when the patient first visited the clinic was significantly higher in 2022 than in 2007. The worst pain intensity during past 6 months was significantly higher in 2022 than in 2007. The findings of the present study suggested that the pathology and complaint of TMD might be change with social situations.
