摘　　要：目的探讨低能量镓铝砷半导体激光对颞下颌关节疼痛的治疗效果。方法将50例颞下颌关节疼痛患者按随机、双盲的原则分为激光治疗组(n=25)和对照组(n=25)。激光治疗组患者采用低能量镓铝砷半导体激光照射治疗,对照组患者采用能发出同样红色指示光的模拟激光照射治疗,两组照射时间均为5 min,每天照射一次,连续照射3 d。每次照射治疗前后均测量患者的开口度、前伸动度、患侧侧方动度、对侧侧方动度、压力疼痛阈值,并对患者进行疼痛视觉模拟评分,记录相应分值,采用重复测量资料的方差分析进行统计分析。结果激光治疗组患者低能量镓铝砷半导体激光治疗后,下颌功能运动状态(P<0.05)、疼痛症状(P=0.001)均有明显改善;对照组患者的下颌功能运动状态和疼痛症状与治疗前相比无明显差异(P>0.05)。结论低能量镓铝砷半导体激光能够有效缓解颞下颌关节疼痛症状,改善其下颌功能运动状态。该激光具有疗程短、效率高、无痛苦、无副作用等优点,有一定的临床应用价值。Objective To investigate the therapeutic effect of low-level Ga-Al-As laser therapy on temporomandibular joint pain.Methods Fifty patients with temporomandibular joint pain were divided into laser treatment group(n=25)and control group(n=25)according to the principle of randomization and double blindness.Patients in the laser treatment group were treated with low-level Ga-Al-As laser therapy,and patients in the control group were treated with simulated laser irradiation that emitted the same red indicator light.The irradiation time of both groups was 5 min,and the irradiation was performed once a day for 3 consecutive days.The patients’maximum vertical opening,protrusion excursion,affected side lateral excursion,offside lateral excursion,pressure pain threshold and visual analogue scale were measured before and after irradiation treatment every time.The corresponding scores were recorded,and analysis of variance of repeated measurements was used for statistical analysis.Results After laser treatment of low-level Ga-Al-As laser therapy,the mandibular functional movement(P<0.05)and pain symptoms(P=0.001)were significantly improved.Patients in the control group showed no significant difference in mandibular functional movement and pain symptoms compared with those before treatment(P>0.05).Conclusion Low-level Ga-Al-As laser therapy can effectively alleviate the symptoms of temporomandibular joint pain and improve the mandibular functional movement.The laser has the advantages of short treatment,high efficiency,no pain,no side effects,and has certain clinical application value.
