目的
评价支持性牙周治疗（SPT），包括口腔预防和口腔卫生指导作为唯一干预（试验）或结合龈下器械清除/破坏龈下生物膜（对照）。
材料和方法
62例牙周炎患者（50.97 ± 9.26岁，24名吸烟者）被随机分配接受试验或对照治疗，在2年内每3个月接受一次。检查包括牙周探诊深度（PPD）、探诊出血（BOP）和临床附着丧失（CAL）。采用广义估计方程进行分析。
结果
两组之间的基线人口统计学和吸烟情况相似。然而，试验组基线时的平均PPD大于对照组（2.32 mm vs. 2.17 mm，p=0.03），但2年后相似（分别为2.23 mm vs. 2.15 mm）。随着时间的推移，观察到PPD和BOP显著降低，CAL增加，但组间无显著差异。在≥ 5 mm的部位，无论性别和吸烟习惯如何，试验组的PPD降低幅度均大于对照组（p=0.034）。两组之间获得或失去附着+/-2 mm的部位分布相似。
结论
在2年的SPT中，单独使用口腔卫生指导或结合龈下器械进行口腔预防能够将先前获得的牙周状况保持在相当的程度上。本文受版权保护。All rights reserved.
AIM
Evaluate supportive periodontal therapy (SPT) consisting of oral prophylaxis with oral hygiene instructions as sole intervention (test) or combined with subgingival instrumentation removing/disrupting the subgingival biofilm (control).
MATERIAL AND METHODS
62 treated periodontitis patients (50.97 ± 9.26 years, 24 smokers) were randomly assigned to receive, every 3 months during 2 years, either test or control treatment. Examination included periodontal probing depth (PPD), bleeding on probing (BOP) and clinical attachment loss (CAL). Generalized estimating equations were used for analyses.
RESULTS
Baseline demographics and smoking were similar between groups. However, at baseline mean PPD was greater in test than control group (2.32mm vs. 2.17mm, p=0.03) but similar after 2-years (2.23mm vs. 2.15mm, respectively). With time, significant PPD and BOP decrease and CAL increase were observed although without significant differences between groups. At sites ≥ 5mm, PPD decrease was greater in test than control group irrespective of sex and smoking habit (p=0.034). The distribution of sites gaining or losing attachment +/- 2mm was similar between groups.
CONCLUSION
Oral prophylaxis with oral hygiene instructions alone or in combination with subgingival instrumentation were able to maintain the previously obtained periodontal condition to a comparable extent during 2 years SPT. This article is protected by copyright. All rights reserved.
