简介：　　【摘 要】目的：探讨牙周炎患者正畸过程中采用牙周序列治疗方式的有效性。方法：随机选取我院于 2017年 7月至 2019年 7月接受正畸治疗的 80例牙周炎患者，并将其分为对照组（ n=40）及研究组（ n=40），其中给予对照组患者单纯正畸治疗，而研究组则在前者基础上联合牙周序列治疗，对两组临床疗效进行评价比较。结果：与对照组相比，研究组患者治疗后 PD（探诊深度）、 PLI（菌斑指数）、 BI（出血指数）、 CAL（临床牙周附着丧失）等指标水平更理想，差异有统计学意义（ P<0.05） ;研究组治疗总有效率为 95.00%，明显高于对照组 70.00%，差异有统计学意义（ P<0.05）。结论：牙周炎患者正畸过程中采用牙周序列治疗，具有积极意义，可在提高患者临床疗效的同时，改善患者的牙周健康指标。  　　【关键词】牙周炎 ;正畸 ;牙周序列 ;治疗  Objective: To investigate the effectiveness of sequential periodontal therapy in the orthodontic treatment of periodontitis. Methods: 80 patients with periodontitis who received orthodontic treatment in our hospital from July 2017 to July 2019 were randomly selected and divided into control group (n = 40) and study group (n = 40). Patients in control group were given orthodontic treatment only, while patients in study group were treated with periodontal sequential therapy on the basis of the former. Results: compared with the control group, Pd (probing depth), PLI (plaque index), Bi (bleeding index), cal (clinical periodontal attachment loss) and other indicators of the study group were more ideal after treatment, the difference was statistically significant (P < 0.05); the total effective rate of the study group was 95.00%, significantly higher than that of the control group 70.00%, the difference was statistically significant (P < 0.05). Conclusion: it is of positive significance to use periodontal sequence therapy in the orthodontic treatment of patients with periodontitis, which can improve the clinical efficacy and periodontal health indicators of patients.
