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.
