摘要/Abstract

摘要： 目的:分析比较内窥镜辅助牙周治疗与传统治疗后牙根表面形态及不同位点治疗后牙骨质差异。方法:选择重度牙周病变Ⅲ度松动需拔除单根牙30颗,拔除后随机分为4组:未处理组、Ultra组、Ultra-Hand组、Ultra-Endo组。患牙处理后进行菌斑染色统计牙石残留率;根面扫描电镜观察;组织切片测量治疗后牙骨质厚度。结果:3种治疗方法均能有效去除根面牙石;Ultra-Endo组根面残留牙石较少,与Ultra组、Ultra-Hand组均有显著性差异;Ultra组与Ultra-Hand组之间差异不明显。扫描电镜观察到Ultra-Hand组根面较平整,刮痕明显,大量沟槽裂隙,Ultra组与Ultra-Endo组根面不平整,尚存在健康牙骨质表面鹅卵石样外观。治疗后牙骨质厚度观察,Ultra-Endo组治疗后牙骨质较其余两组多,有显著差异。结论:内窥镜辅助下清除龈下牙石更彻底,保留较多牙骨质。

Abstract: Objective: To evaluate the cementum thickness and the root morphology after SRP treatment with or without periodontal endoscope in vitro. Methods: Thirty single root teeth with mobility Ⅲ which need to be extracted were collected and divided into 4 groups randomly: no treatment, Ultra group, Ultra-Hand group, and Ultra-Endo group. Plaque Disclosing Agent was used to measure the residue calculus rate. SEM was applied to observe the surface of teeth. Histology method was taken to measure the thickness of cementum. Results: All three test groups had a much lower calculus residual rate than control group (P<0.05), and both Ultra group and Ultra-Hand group had more calculus residual than Ultra-Endo group (P<0.05). Ultra-Hand group showed a smooth surface with homogeneous patchy distribution and cobblestone appearance with debris. Ultra-Endo group and Ultra group showed roughness, and the cobblestone was the same as the surface of health teeth under EMS. The remaining cementum of Ultra-Endo group was more than those of Ultra group and Ultra-Hand group. Conclusions: Subgingival calculus can be removed more thoroughly and clearly and remain more cementum with the help of periodontal endoscope.
