摘要： 目的 探讨单次低剂量激光疗法对固定正畸治疗初期疼痛的影响。方法 选择2015年1月—2017年12月在西宁市口腔医院口腔正畸科进行固定正畸治疗的患者60例,采用随机数字表法分为2组,每组各30例。实验组采用单次低剂量激光疗法治疗,对照组采用安慰剂治疗。应用数字评定量表（NRS）测量2组患者白天、夜间自发性疼痛及咀嚼疼痛强度。采用SPSS 22.0软件包对数据进行统计学处理。结果 实验组用0.012、0.014英寸的超弹性镍-钛（NiTi）线白天及夜间自发性疼痛显著低于对照组(P<0.05),用0.016、0.018英寸NiTi线则无显著差异（P>0.05）;实验组患者用0.012、0.014、0.016、0.018英寸NiTi线咀嚼疼痛显著低于对照组（P<0.05）。结论 单次低剂量激光疗法可显着减轻术后疼痛。

Abstract: PURPOSE: To investigate the effect of single low level laser therapy on initial pain during fixed orthodontic treatment. METHODS: Sixty patients who underwent fixed orthodontic treatment in our hospital from January 2015 to December 2017 were enrolled.Patients were divided into 2 groups by random number table method, 30 in each group. Patients in the experimental group were treated with a single low level laser therapy ,while patients in the control group were treated with a placebo.The results of the 2 groups were compared in regard to spontaneous pain and chewing pain during the day and night using SPSS 22.0 software package. RESULTS: Spontaneous pain during day and night with 0.012, 0.014 inch superelastic nickel-titanium (NiTi) line was significantly lower in the experimental group than in the control group(P<0.05), and there was no significant difference with 0.016 and 0.018 inch NiTi (P>0.05).Chewing pain with 0.012, 0.014, 0.016, and 0.018 inch NiTi lines in the experimental group was significantly lower than that in the control group(P<0.05). CONCLUSIONS: Single low level laser therapy significantly reduced postoperative pain while placing a superelastic NiTi wire for initial alignment and correction.
