摘要/Abstract

摘要： 目的: 比较Nd:YAP激光与三联抗生素糊剂在牙髓血运重建治疗中根管消毒的效果,为牙髓血运重建术中根管内消毒方法提供参考。方法: 选择诊断为急性或慢性根尖周炎的年轻恒牙40颗,记录根尖周病变和牙根发育状况。患牙分为三联抗生素糊剂封药消毒的对照组和Nd:YAP激光消毒的实验组,每组均20颗患牙,均行牙髓血运重建术。术后对每颗患牙行临床检查和X线评价。采用SPSS19.0软件包对数据进行χ²检验。结果: 治疗后1周,对照组和实验组分别有2颗和4颗患牙存在症状;治疗后2周,对照组患牙临床症状均消失,而实验组则有1颗患牙仍有临床症状,差异无显著性（P>0.05）。随访18个月,结果表明,对照组和实验组分别有2颗和3颗患牙临床症状复发, 分别有12颗和10颗患牙X线片上表现为牙根继续发育,分别有3颗和4颗患牙X线片上未观察到明显的牙根继续发育。对照组和实验组结果差异无显著性（P>0.05）。结论: Nd:YAP激光可进行有效的根管消毒,且对牙髓血运重建术的预后无明显影响。

Abstract: PURPOSE: To compare the effect of Nd:YAP laser and Hoshino's triple antibiotic paste on root canal disinfection in the treatment of pulp revascularization, and to provide reference for root canal disinfection in dental pulp revascularization. METHODS: Forty immature permanent teeth diagnosed as acute or chronic periapical periodontitis were included. The periapical lesions and root development were recorded. The cases were divided into 2 groups: the control group and the Nd:YAP laser disinfection experimental group. Clinical examination and X-ray evaluation of each case were performed after treatment. Statistical analysis was performed using SPSS 19.0 software package. RESULTS: Two cases showed symptoms in control group 1 week after treatment, while 4 cases had symptoms in the experimental group. The clinical symptoms disappeared in the control group 2 weeks after treatment, while 1 case still had symptoms in the experimental group. There was no significant difference between the two groups (P>0.05). Clinical evaluation at 18 months of follow-up showed that 2 and 3 cases had recurrent symptoms in the control group and the experimental group, respectively; continuous development of the root was noted in 12 and 10 cases on X-ray film in the control and experimental group, respectively, while 3 and 4 teeth had no obvious root development in the control and experimental group, respectively. There was no significant difference between the control group and the experimental group (P>0.05). CONCLUSIONS: Nd:YAP laser can be used for effective root canal disinfection without obvious effect on the prognosis of dental pulp revascularization.
