咬合运动与注射醋酸泼尼松龙治疗滑膜炎的疗效比较

目的:比较咬合运动和关节下腔注射醋酸泼尼松龙治疗颞下颌关节滑膜炎的临床效果。方法:选择牙列完整、无第三磨牙阻生、符合颞下颌关节滑膜炎诊断标准的120例患者,随机分为实验组和对照组,每组60例。实验组行咬合运动,每次3-4个循环,每日3-4次,治疗周期为12个月;对照组给予醋酸泼尼松龙0.0125g+0.5ml2%利多卡因关节下腔注射一次,比较两种方法的治疗效果。结果:实验组的60例患者均在治疗后1-2w疼痛消失,追踪3-12个月无复发。对照组的60例患者,2个周后有18例无效,无效率为30%,两组比较其结果有显著性差异(P<0.001);3个月后有22例无效,无效率为36.67%,两组比较其结果有显著性差异(P<0.001)。结论:咬合运动组的治疗效果显著高于醋酸泼尼松龙注射组,咬合运动能有效的治疗滑膜炎并减少患者的治疗痛苦。

Comparative Observations of Effects of Articulation Training and Intraarticular Injection of Prednisolone Acetate on Temporomandibular Joint Synovitis

Objective: To investigate the clinical therapeutic efficacy of articulation training and prednisolone acetate intraarticular injection on temporomandibular joint (TMJ) synovitis. Methods: 120 patients, with regular dentition, wothout impacted molar, suffering from TMJ synovitis, were randomly divided into experimental and control groups, each group contained 60 patients. Patients in the experimental group were instructed to do articulation training. The repeated movement includes 3-4 cycles of oral movements, and the patients were required to do 3-4 times of articulation exercise each day. The cases in the control group received intraarticular injection of prednisolone acetate 0.0125g+0.5ml 2% lidocaine hydrochloride injection one time. The effects of two groups were detected and traced. Results: All patients in the experimental group were cured of the pain without recurrence, within 1-2 weeks of treatment, in the following 3-12 months. While 18 patients in the control group showed invalid 2 weeks after treatmen, which meant the invalid rate was 30%, the invalid rate of the experimental group was significantly lower than that of the control group (P<0.001); 21 patients in the control group showed invalid 3 months after treatment, which meant the invalid rate was 36.67%, the invalid rate of the experimental group was significantly lower than that of the control group (P<0.001). Conclusion: Articulation training significantly surpassed intraarticular injection of prednisolone acetate in curing TMJ synovitis and relieving pains incurred by treatment.
