|
|
A retrospective study was conducted to determine the patterns of Temporomandibular Disorder(TMD) among adolescents (12-19 years) over last ten years. 174 patients who had visited the Oral medicine of Pusan National University Dental Hospital in 2000 and 491 patients in 2008 were found on chart review. The results obtained were as follows :
1. The number of adolescent patients was significantly increased in 2008 than in 2000, especially in male.
2. Bruxing, clenching, holding habits and bad sleep hygiene were highly increased more in 2008 than in 2000.
3. Osteoarthritis was significantly increased in 2008 than in 2000 and anterior disc dislocation without reduction was slightly increased.
4. The ratio of male to female adolescent patients with osteoarthritis was remarkably increased. Among the patients who had holding, bruxing, clenching habits, significantly increased osteoarthritis found to be common. This could imply holding, bruxing, clenching habits are prominently associated with increasing risk of developing osteoarthritis.
