中文摘要
目的 对比成人正畸患者应用无托槽隐形矫治技术与传统固定矫治技术的牙周指数、变异链球菌和牙龈卟啉单胞菌的变化。方法 选择成人正畸患者30例,分为2组,实验组15例应用无托槽隐形矫治技术,对照组15例应用固定矫治技术。分别在矫治器戴入前,戴入后第1、3个月检查临床牙周指标[包括菌斑指数(PLI)、牙龈出血指数(SBI)、探诊深度(PD)],同时采集菌斑,利用实时荧光定量聚合酶链反应检测样本中变异链球菌、牙龈卟啉单胞菌和总细菌的数量,计算出变异链球菌和牙龈卟啉单胞菌的构成比。将临床牙周指数、变异链球菌和牙龈卟啉单胞菌构成比进行组间对比和组内不同时间点对比。结果 治疗前实验组与对照组牙周指数、变异链球菌和牙龈卟啉单胞菌构成比差异无统计学意义(P>0.05);治疗中,实验组牙周指数、变异链球菌和牙龈卟啉单胞菌构成比均低于对照组(PPP>0.05),对照组牙周指数、变异链球菌和牙龈卟啉单胞菌构成比均随时间延长而升高(P
英文摘要
Objective This study aims to compare the periodontal indices and the percentage ofStreptococcus mutansandPorphyromonas gingivalisbetween adult patients with bracketless invisible aligner and conventional brackets. Methods Thirty adult patients were divided into two groups(experimental group:15 patients with bracketless invisible aligner; and control group:15 patients with conventional brackets). The clinical periodontal indices[plaque index(PLI), sulcus bleeding index(SBI), and probing depth(PD)] of the observed teeth were examined at three different time points: before orthodontic treatment and in the first and third months after treatment. Dental plaques were collected simultaneously at each time point. We used real-time quantitative polymerase chain reaction to detect and quantitate the number of totalStreptococcus mutansandPorphyromonas gingivalisin each sample to determine the percentage ofStreptococcus mutansandPorphyromonas gingivalisof total bacteria. Results Before treatment, the periodontal indices and the percentage ofStreptococcus mutansandPorphyromonas gingivalisof total bacteria showed no difference between the two groups(P>0.05). Moreover, the periodontal indices and the percentage ofStreptococcus mutansandPorphyromonas gingivalisof total bacteria were significantly lower in the experimental group than in the control group(PStreptococcus mutansof total bacteria of the experimental group also increased with time(PPorphyromonas gingivalis of total bacteria also showed no difference between the two groups(P>0.05). The periodontal indices and the percentage ofStreptococcus mutansandPorphyromonas gingivalisof total bacteria of the control group also significantly increased with time(P
