Abstract:

Objective　This study aimed to understand the effect of implementing the comprehensive intervention pro-ject for pediatric oral diseases on the oral health status, health knowledge, attitudes, and behavior of 12-year-old children in the intervention and non-intervention areas of Guizhou Province where the project was implemented. Methods　The oral health data of 12-year-old children in Guizhou Province were collected from the oral health epidemiological survey of the province from June 2019 to November 2020, and six areas were selected from each project intervention and non-intervention area, with a total of 2 654 children. The oral health status, oral health knowledge, attitude, behavior, dental service utilization, and sugar diet of 12-year-old children in the project intervention and non-intervention areas were compared. Results　The prevalence of caries, average caries, periodontal status, utilization rate of dental services, oral health knowledge, attitude, and behavior of 12-year-old children in the project intervention areas were better than those in the non-intervention areas, and the number of retained teeth with cavity and ditch sealing agent was higher in the project intervention area, with statistically significant difference (P<0.05). However, no significant difference was observed in the number of dental caries, caries filling ratio, and sugar diet (P>0.05). Conclusion　The comprehensive intervention program for children’s oral diseases in Guizhou Province has a potential role in improving the oral health status, oral health knowledge, and health behavior of 12-year-old children in Guizhou Province. The comprehensive intervention of children’s oral diseases could be more helpful to improve and enhance the oral health status and literacy of school-age children in Guizhou Province.
