Comparative Analysis : The Patterns of Temporomandibular Disorder among Adolescents

Abstract

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.

Local Injection of Growth Hormone for Temporomandibular Joint Osteoarthritis

“…OA in middle-aged to older adults appears to be accompanied by degenerative joint changes, whereas OA in adolescents does not display a degenerative etiology. 4 Therefore, many attempts have been made to determine the etiology of OA in accordance with etiologic factors, such as genetic factors, parafunctional habits, occlusal disturbance, and sudden dental treatment, 1,22 and to develop treatments to eliminate these etiologic factors. Treatment options include physical therapy, medication, stabilization splint therapy, and behavioral therapy.…”

“…2,3 One study investigating the demographics of patients visiting an orofacial pain clinic in South Korea noted an increase in young TMD patients with OA from 9% in 2000 to 39% in 2008. 4 TMJ-OA that starts at a young age inevitably leads to facial deformity and malocclusion. 5 To solve these problems, orthodontic treatment with orthognathic surgery is generally required.…”

Comparative evaluation of bony changes in temporomandibular joint osteoarthritis in patients with and without Generalized Osteoarthritis

“…6 However, recent research has identified TMJ OA in the majority of young patients with TMJ pain and dysfunction 7,8,9 . Furthermore, Ok et al 10 reported that TMJ OA is significantly increased in adolescents over the last several years (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008). In the TMJ, the most common signs and symptoms of OA is palpable tenderness of the joint, crepitation, and limited mandibular movement.…”

“…Joint pain is usually mild in the morning and gets worse in the evening after a day's activity. 11,12 With advanced degeneration, the subchondral cortical layer is lost and erosion and other radiographic signs of OA appear 10,13 . The radiographic signs of TMJ OA are as follows: subchondral bone sclerosis, erosion, flattening/irregularities or deformation of the surface of the mandibular condyle, osteophytes formation and reduction of joint space 7,10,14,15,16,17,18,19 .…”
