咬合板加局部激光照射治疗颞下颌关节紊乱病的临床研究

目的:研究咬合板加局部激光照射对颞下颌关节紊乱病(TMD)的临床治疗效果。方法:TMD患者225例,随机分为咬合板+局部激光照射组、局部封闭治疗+局部激光照射组、局部激光照射组,每组75人。局部封闭治疗:2%利多卡因1 mL+醋酸强的松龙混悬液2 mL行痛点封闭,每周1次,3～5次为一疗程。咬合板治疗:夜间佩戴下颌平面抬高约4 mm的咬合板。激光治疗:用MDC-500IP型半导体激光治疗机照射颞下颌关节区,1次/d,10 d为一疗程。结果:总有效率"咬合板+局部激光照射组"为93.33%,"局部封闭治疗+局部激光照射组"为85.02%,"局部激光照射组"为70.67%。组间差异有统计学意义(P<0.05)。结论:"咬合板+局部激光照射"治疗TMD较为有效,值得推广。

Occlusal Splint Combined with Local Laser Irradiation in the Management of Temporomandibular Disorders

Objective: To evaluate the clinical effects of occlusal splint and local laser irradiation in the treatment of temporomandibular disorders.Methods: 225 temporomandibular disorder(TMD) patients were randomly divided into 3 groups(75 patients in each) and their treatment results were retrospectively reviewed.In group A,occlusal splint and local laser irradiation were used.In group B,a local block injection were used combining with local laser irradiation.In group C,local laser irradiation were used only.Block injection solution was 1 mL 2% lidocaine and 2 mL acetic prednisolone suspension once a week for 3-5 weeks.An occlusal splint was fabricated to elevate mandible occlusal level for 4 mm at night.MDC-500IP semiconductor laser construction was used to irradiate temporomandibular joint area once a day and 10 days as a period of treatment.Results: The effective rate of group A、B、C were 93.33%,85.02% and 70.67% respectively.Conclusion: The occlusal splint combined with local laser irradiation may be a comparatively beneficial treatment for TMD,which is worthy clinical application.
