半导体激光辅助治疗78例窦道型根尖周脓肿的效果观察

目的: 探讨半导体激光在窦道型根尖周脓肿治疗中的效果。方法: 选取窦道型根尖周脓肿患者78例,随机分为试验组和对照组,每组各39例。对照组采用常规根管预备及氢氧化钙封药,试验组在常规根管预备的基础上,采用半导体激光根管内照射后再用氢氧化钙封药,观察和评价2组患者的瘘管愈合情况。采用SPSS19.0软件包对数据进行统计学分析。结果: 试验组39例患者根管治疗后再次复诊时仅1例窦道未愈合,有效率为97.44%;对照组39例患者根管治疗后再次复诊时9例患者未能愈合,有效率为76.92%,2组之间差异显著（P<0.05）。结论: 半导体激光治疗瘘管型根尖周脓肿效果良好,值得推广应用。

Effect of diode laser in the treatment of 78 patients with sinus chronic apical abscess

PURPOSE: To explore the effect of diode laser in the treatment of sinus chronic apical abscess. METHODS: A total of 78 patients with sinus chronic apical abscess were randomly divided into experimental group and control group, 39 cases in each group. Patients in the control group were treated with conventional root canal preparation and calcium hydroxide sealant. After conventional root canal preparation, the canals in the experimental group were disinfected with diode laser and then calcium hydroxide sealant. SPSS 19.0 software package was used for data analysis. RESULTS: Of 39 patients in the experimental group, only 1 sinus was not healed,the total effective rate was 97.44%;Of 39 patients in the control group,9 sinuses were not healed, the total effective rate was 76.92%. The difference between the two groups was statistically significant. CONCLUSIONS: The results show that the effect of diode laser in the treatment of sinus chronic apical abscess is better, which is worthy of wide application.
