Long term follow-up study on the preventive effect of oral hygiene behavior intervention on periodontitis
口腔卫生行为干预对牙周炎预防效果的长期随访研究

摘要

目的 探讨口腔卫生行为干预对牙周炎预防的长期效果。方法 将2021年1月—2022年1月在本院口腔科进行口腔健康检查的56例牙周健康人群作为研究对象，以随机数字表法分为常规组及实验组，每组28例。常规组采取常规口腔健康指导干预，实验组在常规指导基础上采取系统性口腔卫生行为干预。对两组研究对象进行为期1年的随访，对比两组干预前、干预1年的口腔卫生指标（菌斑指数PLI、牙龈指数GI）、牙周健康指标（牙周探诊深度PD、附着丧失AL）。结果 实验组干预1年后PLI、GI、PD、AL均低于常规组（P<0.05）。结论 口腔卫生行为干预可有效改善研究对象的口腔卫生状况，延缓牙周组织病变进展，对牙周炎具有更优的长期预防效果，值得临床推广。

Abstract

Objective To explore the long-term effect of oral hygiene behavior intervention on the prevention of periodontitis.
Methods 56 periodontal healthy individuals who underwent oral health examinations in the Department of Stomatology of our hospital from January 2021 to January 2022 were selected as the study subjects. They were randomly divided into a control group and an experimental group using a random number table method, with 28 cases in each group. The conventional group received routine oral health guidance intervention, while the experimental group received systematic oral hygiene behavior intervention based on routine guidance. Two groups of study subjects were followed up for one year to compare their oral hygiene indicators (plaque index PLI, gingival index GI) and periodontal health indicators (periodontal probing depth PD, attachment loss AL) before and after one year of intervention.
Results After 1 year of intervention, PLI, GI, PD, and AL in the experimental group were lower than those in the control group (P<0.05).
Conclusion   Oral hygiene behavior intervention can effectively improve the oral hygiene status of research subjects, delay the progression of periodontal tissue lesions, and have better long-term preventive effects on periodontitis, which is worthy of clinical promotion and application.
