Abstract：
This study aimed to evaluate the prevalence of osteopenia/osteoporosis in patients with bilateral temporomandibular joint osteoarthritis (TMJ-OA) and its correlations with clinical and radiological findings. A total of 95 patients with bilateral TMJ-OA diagnosed by CBCT were included in the study. Clinical and radiological findings and bone mineral density (BMD) scores were recorded. Descriptive statistics and the Spearman rho correlation tests were performed. Osteopenia/osteoporosis was found in 44 of 95 patients (46.32 %) (30, osteopenia; 14 osteoporosis). Osteopenia/osteoporosis is significantly associated with postmenopausal status and age over 40 years, but it is not associated with clinical and radiological findings of TMJ-OA. Patients with bilateral TMJ-OA have a high prevalence of osteopenia/osteoporosis.
摘要：
本研究旨在评估双侧颞下颌关节骨关节炎（TMJ-OA）患者骨质减少/骨质疏松症的患病率及其与临床和放射学检查结果的相关性。共有95例经CBCT诊断的双侧TMJ-OA患者被纳入研究。记录临床和放射学发现以及骨矿物质密度（BMD）评分。进行描述性统计和Spearmanrho相关性检验。95例患者中有44例（46.32％）发现骨质减少/骨质疏松（30例骨质减少；14例骨质疏松）。骨质减少/骨质疏松症与绝经后状态和40岁以上的年龄显着相关，但与TMJ-OA的临床和影像学表现无关.双侧TMJ-OA患者骨量减少/骨质疏松症的患病率很高。
