Background: This study was done to better understand patterns, trends and local distribution patterns of malocclusion so that we can provide adequate information to patients, to help make the appropriate diagnosis and therapeutic plans, and to assess the future directions of malocclusion treatment. Materials and Methods: Malocclusion patterns, distribution and trends of visiting patients were examined in 993 malocclusion patients who had been evaluated and diagnosed at the Department of Dentistry, Yeungnam University Hospital over a 10-year period from 1995 to 2004. Results: The number of visiting patients per year showed an increasing trend and the visit rate was 1.28 time-higher in females(56.1%) than in males(43.9%). 1) Age distribution showed that the 7-12 year-old group was the largest (36.7%). Geographic distribution showed the majority of patients were from the Dalseo district(28.2%). Angle's malocclusion classification revealed that class III was the largest(38.4%). Crowding was the chief complaint in the highest percentage of patients(33.9%). The therapeutic method used was the fixed appliance in 61% of cases and a combination with extraction in 30.8%. Conclusions: The availability of dental services can accommodate orthodontic needs adequately as well as obtain reliable quantitative information regarding the characteristics of orthodontic patients.

This study is designed to evaluate the treatment outcome of occlusal stabilizing splint and to assess follow-up study of condylar bony changes using cone beam computed tomography(CBCT) in adolescents patients (12-19 years) with TMJ osteoarthritis(OA). 167 eroded condyles in 149 subjects were chosen among the patients who presented to the Department of Oral Medicine of Pasan National University Hospital, diagnosed as TMJ osteoarthritis by clinical exam, x-ray and CBCT from 2009 to 2012. They were treated conservatively with physical therapy, medication, behavioral therapy and occlusal stabilizing splint therapy. After average 9 months, CBCT was retaken and subjective symptoms and clinical findings were investigated. Condyle bony changes were classified by unchanged, less severe and more severe. The obtained results were as follow: 1. Pain, Noise, LOM(Limitation of motion) and MCO(Maximum comfortable opening) measurement of TMJ OA patients were markedly improved after conservative treatment. 2. In the occlusal stabilizing splint therapy group, Pain and LOM were statistically significant improved than non-occlusal stabilizing splint therapy group. 3. In the acute occlusal stabilizing splint therapy group, Pain and LOM were remarkably improved. 4. In comparison of CBCT1 and CBCT2 images, the transition of bone changes to lesser severe was most commonly in joint with erosive change. 5. In the non-occlusal stabilizing splint therapy group, the transition of condylar bone changes from erosion to more severe was many than occlusal stabilizing splint therapy group.
