Correlation between early intervention of periodontal disease and influencing factors in 12-year-old middle school students

Abstract Aim Periodontal diseases are gradually becoming public health challenges around the world. This study aimed to explore the relationship between periodontal intervention and the risk of early periodontal disease. Materials and Methods This survey uses stratified sampling to select Luohu District, Nanshan District and Longhua District. All 12-year-old students in the first grade of junior high school in the project school (or some of the classes) are targeted for the project. We adopted the plaque index (PI), calculus index (CI), and bleeding index as the contents of our periodontal health examination. Descriptive statistical analysis was mainly used. The multi-class data analysis was performed by chi-square test. The analysis of influencing factors and intervention measures adapt logistics regression analysis. Results A total of 964 people underwent the periodontal health check and questionnaire in this study. A logistic regression model was used to assess the risk of periodontal disease between the intervention group and the control group. Overall, we found significant differences in the risk of related periodontal diseases (periodontal disease OR 1.999; 95%CI: 1.500 ~ 2.664, buccal gum bleeding OR 1.472; 95%CI: 1.134 ~ 1.910, lingual gum bleeding OR 2.085; 95%CI: 1.576 ~ 2.758 and calculus OR 2.093; 95%CI: 1.600 ~ 2.737) between the intervention group and the control group. Except for plaque, the risk of disease is not significant. Conclusions Our study validated the relationship between periodontal intervention and reduced risk of periodontal disease. This research provided a scientific basis for preventing and controlling the occurrence and development of adolescent periodontal disease.
