Nd:YAG激光对颞下颌关节疼痛的疗效评价

Therapeutic evaluation of Nd:YAG laser therapy on temporomandibular joint pain

目的探讨Nd:YAG激光治疗颞下颌关节疼痛的临床效果。方法选取2019年11月至2020年12月苏州卫生职业技术学院附属口腔医院收治的90例颞下颌关节疼痛的患者作为研究对象,根据随机数字表法将患者分为激光组(30例)、对照组(30例)和热敷组(30例)。激光组采用Nd:YAG激光照射治疗,对照组采用假Nd:YAG激光照射治疗,热敷组使用温热毛巾局部热敷。比较三组治疗前后的疼痛视觉模拟评分法(VAS)评分、最大开口度、下颌偏斜及最大前伸运动度。结果治疗后激光组的VAS评分低于对照组和热敷组,差异有统计学意义(P<0.05);治疗后激光组的最大开口度和最大前伸运动度大于对照组和热敷组,开口偏斜度小于对照组和热敷组,差异有统计学意义(P<0.05)。结论Nd:YAG激光能够有效缓解颞下颌关节疼痛症状,并改善下颌运动程度,是一种可靠的无创治疗方法,值得推广。

Objective To evaluate the effect of Nd:YAG laser therapy on temporomandibular joint pain.Methods A total of 90 patients with temporomandibular joint pain who were admitted to the Stomatological Hospital Affiliated Suzhou Vocational Health College from November 2019 to December 2020 were selected as the research subjects.The patients were divided into laser group(30 cases),control group(30 cases)and hot dressing group(30 cases)according to the random number table method.The laser group was treated with Nd:YAG laser irradiation,the control group was treated with fake Nd:YAG laser irradiation,and the hot compress group was treated with warm towel.The visual analogue scale(VAS)score,maximum opening,mandibular deflection and maximum extension motion before and after treatment were compared among the three groups.Results After treatment,VAS score of laser group was lower than that of control group and hot compress group,the difference was statistically significant(P<0.05).After treatment,the maximum opening degree and the maximum extension motion of the laser group were greater than those of the control group and the hot compress group,and the opening skew was less than that of the control group and the hot compress group,the differences were statistically significant(P<0.05).Conclusion Nd:YAG laser can effectively relieve the symptoms of temporomandibular joint pain and improve the degree of mandibular movement,which is a reliable and non-invasive treatment method,and is worth popularizing.
