The objective of this study was to evaluate the usefulness of bone scan procedures for the diagnosis of temporomandibular joint (TMJ) osteoarthritis.
From February 2009 to June 2009, 22 patients (4 males and 18 females) from Seoul National University Bundang Hospital, Republic of Korea, were diagnosed with TMJ disorder. They were examined by clinical examination, plain radiograph and bone scan and were categorized into three groups: normal, internal derangement and osteoarthritis. TMJ uptake ratios and asymmetrical indices were calculated.
There were no significant differences in uptake ratios associated with pain and bone change. However, significant results were obtained when comparing uptake ratios between the osteoarthritis and non-osteoarthritis groups.
It was concluded from this study that bone scans may help to diagnose osteoarthritis when increased uptake ratios are observed.
本研究旨在评估骨扫描程序在诊断颞下颌关节（TMJ）骨关节炎中的作用。
2009 年 2 月至 2009 年 6 月，韩国首尔国立大学盆唐医院收治了 22 名患者（男 4 例，女 18 例），均被诊断为 TMJ 紊乱。对其进行了临床检查、普通 X 线片和骨扫描检查，并分为三组：正常、内部紊乱和骨关节炎。计算了 TMJ 摄取率和不对称指数。
疼痛和骨改变相关的摄取率无显著差异。然而，在比较骨关节炎和非骨关节炎组的摄取率时，结果具有统计学意义。
本研究表明，当观察到摄取率增加时，骨扫描有助于诊断骨关节炎。
