目的:评价Mini Five型Gracey手工刮治器结合盐酸米诺环素治疗磨牙Ⅱ度根分叉病变的的临床疗效。方法:32例患者的68个Ⅱ度根分叉病变磨牙进行配对分组治疗。实验组患牙在常规超声龈下刮治后应用Mini Five型Gracey手工刮治器进行根面平整,局部注入盐酸米诺环素软膏,每周1次,共4次;对照组患牙在常规超声龈下刮治后应用标准型Gracey手工刮治器进行根面平整。比较两组患牙治疗后5周的菌斑指数(PLI)、龈沟出血指数(BI)、探诊深度(PD)和水平探诊深度(HPD)四项临床指标以及治疗成功率。结果:①.两组患牙的PLI、BI、PD和HPD均较基线时有改善(P<0.05);②.实验组指标的改善明显优于对照组,两组间的差异有统计学意义(P<0.01),且实验组的成功率为85.29%,明显高于对照组52.94%(P<0.01)。结论:应用Mini Five型Gracey手工刮治器结合盐酸米诺环素软膏治疗磨牙Ⅱ度根分叉病变,能取得较好的临床效果。
Objective: To evaluate the clinical efficacy of the Mini Five-type Gracey hand scraping device combined with minocycline hydrochloride in the treatment of degree Ⅱ root bifurcation lesions. Methods: A total of 68 Ⅱ degree root bifurcation molars in 32 patients were treated with matching grouping. Experimental group of teeth in the conventional ultrasound subgingival curettage using Mini Five Gracey hand scraping device for the root surface formation, local injection of minocycline hydrochloride ointment once a week for a total of 4 times; the control group of teeth in the conventional Ultrasound subgingival scaling after the application of standard Gracey hand scraping device root level formation. Four clinical indexes including plaque index (PLI), sulcus bleeding index (BI), probing depth (PD) and probing depth (HPD) of the two groups of teeth after 5 weeks of treatment were compared with the success rate of treatment. Results: ①The PLI, BI, PD and HPD of the two groups of teeth were improved from the baseline (P <0.05); ②The improvement of the experimental group was obviously better than the control group, the difference between the two groups was statistically significant (P <0.01). The success rate of the experimental group was 85.29%, which was significantly higher than that of the control group (52.94%, P <0.01). Conclusion: Mini Five-type Gracey hand scraping device combined with minocycline hydrochloride ointment for the treatment of molars Ⅱ degree root bifurcation lesions, can achieve better clinical results.
