Analysis of the incidence and influencing factors of dental caries and periodontitis in children aged 5-12 in Jinhua, Zhejiang province.

This study aims to examine the prevalence of dental caries and periodontitis among children aged 5-12 years in Jinhua, Zhejiang province, and analyze the influencing factors of dental caries and periodontitis. A total of 280 children meeting the study criteria for a first-time oral examination were retrospectively analyzed and divided into caries (n = 190), no-caries (n = 90), periodontitis (n = 85) and non-periodontitis group (n = 195) groups based on the presence of caries or periodontitis. An analysis of general survey questionnaires and logistic regression of dental caries and periodontitis among children in different groups was conducted. Caries disease was diagnosed in 67.86% with an average decayed missing filled tooth (DMFT) of 2.94, and periodontitis was diagnosed in 30.36% of 280 children. The independent risk factors for dental caries were daily brushing habits, parental supervision (assisted) brushing, place of residence and frequency of eating desserts or beverages (p < 0.05). Periodontitis was not related to parental education and knowledge of oral health care (p > 0.05). Periodontitis is independent of plaque, tartar, mastery of brushing methods, regular oral examination, and gargling after meals (p < 0.05). While daily brushing habits, parental supervision (assisted) brushing, place of residence and frequency of eating desserts or beverages were protective factors for dental caries (p < 0.05). According to the prevalence of dental caries and periodontitis among children aged 5-12 in this area as well as the analysis of influencing factors, further effective measures can be taken to reduce the incidence of adverse influencing factors, thereby reducing the risk of dental caries and periodontitis for children.
