Abstract：Objective To observe the oral health behavior of children in Shunyi District of Beijing and to analyze the correlation between oral health behavior and the occurrence of dental caries. Methods The physical examination data of 469 children aged between 11 and 12 years old in the Hospital of Shunyi District Beijing from January 2017 to January 2018 were selected as the research objects. All the children received dental health examination, and oral health behaviors were investigated by using the oral health epidemiology questionnaire in Shunyi District, Beijing. The incidence of caries in children was observed, and all children were divided into occurrence group and non-occurrence group according to the incidence of dental caries, the effects of oral health behaviors on the occurrence of dental caries were analyzed. Results Of the 469 children, 85 children had dental caries, with an incidence rate of 18.12%; the proportion of effective brushing (occasionally or never), the age to start brushing (＞ five years old), the frequency of brushing teeth (once a day), the frequency of not using fluoride toothpaste, the frequency of sweets eating (≥two times a day), and the proportion of no regular oral health examination in the occurrence group were all higher than those in the occurrence group (P ＜ 0.05); brushing their teeth checked by logistic regression analysis results showed that the effective case (occasionally OR never), start brushing age (＞ five years old), number of brushing teeth every day (once a day), without the use of fluoride toothpaste, frequency of sweets to eat every day (≥two times) OR higher, not regular oral health inspection are the influence factors in the devebopment of dental caries in children (OR ＞ 1, P ＜ 0.05). Conclusion There are differences in oral health behaviors among children in Shunyi District of Beijing, bad oral health behaviors may be the main cause of dental caries, and there is a significant correlation between them. In order to reduce the incidence of dental caries, it is necessary to evaluate children’s oral health behaviors as early as possible and take appropriate interventions.
