Study of Internal Derangement of Temporomandibular Joint in Bihar Population: A Mystery
Background: Internal derangements of temporomandibular joint (TMJ) are conditions in which articular disc has become displaced from its origin position the condylar head. This displacement causes musculature, ligaments, and impairment.
Materials and Methods: Patients of different age groups were studied. The patients having signs and symptoms of temporomandibular disorders and research diagnostic criteria positivity were studied.
Results: 4 (6.15%) were below 18 years, 7 (10.7%) were aged between 18 and 35 years, 19 (29.2%) aged between 36 and 50, 23 (35.3%) were between 51 and 65, and 19 (18.4%) were >65 years of age. The clinical manifestations were as follows: 23 (35.3%) had myofascial pain dysfunction syndrome, 19 (29.3%) had osteoarthritis, 26 (40%) had clicking sound, 17 (26.1%) had crepitus, 4 (6.1%) had joint tenderness, and 27 (41.5%) had deviation of mandible on opening.
Conclusion: This study implies that TMJ. derangements are not uncommon; however, they are self-limiting and respond well to conservative, inexpensive care. In the rare cases, surgical intervention may require.
