目的:探讨Nd∶YAG激光和传统根尖外科手术治疗窦道型根尖周炎的疗效差异。方法:将54例窦道型根尖周炎的患牙随机分成Nd∶YAG激光治疗组和传统根尖外科手术治疗组,在Nd∶YAG激光治疗组中,将Nd∶YAG激光光纤头沿瘘管插入根尖,然后缓慢旋转后退照射瘘管避,重复照射3次,并配合生理盐水冲洗。传统根尖外科手术组采用手术治疗患牙。分别对两组患牙进行术后48h反应情况、术后10天情况和术后3个月情况进行复查。结果:术后48hNd∶YAG激光处理组的术后反应明显较常规手术组轻(P=0.000)。两组数据有显著差异性。术后10天Nd∶YAG激光处理组和常规手术组在术后10天的疗效相同(P=0.655)。术后3个月Nd∶YAG激光处理组和常规手术组的疗效相同(P=0.541)。结论:Nd∶YAG激光在治疗窦道型根尖周炎方面与传统根尖外科手术相比在治疗效果方面没有明显差异,且Nd∶YAG激光治疗后,患牙的术后不适反应更轻,因Nd∶YAG激光在治疗过程中的创伤更小,更加安全,所以其临床适用范围较传统根尖外科手术更广,值得推广。
Objective: To investigate the therapeutic effect of Nd:YAG laser and traditional apical surgery on sinus periapical periodontitis. Methods: Totally 54 patients with sinus periapical periodontitis were randomly divided into Nd:YAG laser group and conventional apical surgical group. In Nd:YAG laser group, the Nd:YAG laser fiber was placed along fistula Insert the apical, and then slowly rotate back fistula avoidance, repeated irradiation 3 times, and with saline wash. Traditional apical surgery group with surgical treatment of teeth. The response of the two groups of teeth to postoperative 48h, postoperative 10 days and postoperative 3 months were reviewed. Results: Postoperative 48h NdDYY laser treatment group postoperative response was significantly lighter than the conventional surgery group (P = 0.000). Two sets of data have significant differences. At 10 days after operation, Nd:YAG laser treatment group and conventional surgery group had the same effect 10 days after operation (P = 0.655). The efficacy of Nd: YAG laser at 3 months after surgery was similar to that of the conventional surgery group (P = 0.541). Conclusion: Nd: YAG laser has no significant difference in the therapeutic effect compared with the traditional apical surgery in the treatment of periapical periodontitis of the sinuses. After Nd: YAG laser treatment, the postoperative discomfort response of the teeth is lighter, Nd: YAG laser in the treatment of trauma is smaller, more secure, so its clinical scope than the more radical apex surgery, it is worth promoting.
