Abstract

Temporomandibular disorder (TMD) is a common and complicated disease that greatly affects quality of life. Clinical manifestations of TMD are diverse and create challenges in diagnosis and treatment. Determining the common as well as the prognostic indicating signs and symptoms in TMD is necessary and a priority. We conducted a study on 80 patients with TMD who were treated at O'care Dental Office from 2019 to 2021. The results show that the number of female patients is 3 times higher than that of male patients, and the group of patients under 30 years old is twice as high as the group above 30 years old with a mean age of 27.2 years. For the characteristics of functional symptoms, the rate of joint sounds, arthralgia and myalgia accounted for a rather high rate (86.3%, 56.3%, 43.8%), of which 48% of cases had severe pain (7- 9 points) and 8.8% unbearable pain (10 points) showed that pain was the strongest motivating factor for patients to come for treatment. The most painful muscle groups are the superior lateral pterygoid, medial pterygoid, temporal and masseter muscles with the rate from 71.3% to 81.3%. In the joints, pain was mainly shown in the TMJ ligament and capsule (53.8% and 50.0%). Up to 86.3% have joint sounds, indicating that there may be a close relationship between intra-articular disorders and TMD. Jaw movement disorders are mainly limited opening and deviated opening, although the rate is not high (46.3%) but these are important prognostic indicators in the diagnosis and treatment of patients with TMD.
