摘要 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 difference of clinical effects between Nd:YAG laser and traditional apical surgery about treating sinus apical periodontitis.Method:54cases were randomly classified into two groups,one was called Nd:YAG laser group,the other was called traditional apical surgery group,Nd:YAG laser group included 26 specimens whose sinuses were irradiated with Nd:YAG laser,traditional apical surgery group included 26 specimens which were treated with traditional apical surgery.48 hpostoperative reaction,10 days postoperative effects and 3months postoperative effects were compared.Result:The postoperative reaction of Nd:YAG laser group is much slighter than the traditional apical surgery group.The differences of postoperative effects after 10 days and after 3months between Nd:YAG laser group and traditional apical surgery group was not statistically significant.Conclusion:Nd:YAG laser and traditional apical surgery don't have significant difference in treating sinus apical periodontitis.After the treatment of Nd:YAG laser,the postoperative reaction is much slighter.Nd:YAG laser is more safer,have less trauma than traditional apical surgery,it can be generally used in the future.
