Prevalence of first permanent molar caries and its influencing factors among 12-year-old children in Chongqing
Objective To understand the prevalence of first permanent molar caries and its influencing factors among 12-year-old children in Chongqing,providing recommendations for comprehensive interventions in children's dental health.Methods A random cluster sampling method was employed to select 12-year-old children from six districts and counties in Chongqing for a questionnaire survey and dental health examination.Statistical analysis was conducted using SPSS 25.0,and multivari-ate logistic regression was used to analyze factors influencing the prevalence of first permanent molar caries.Results A total of 3 770 12-year-old children were surveyed,with 1 953 boys(51.80％)and 1 817 girls(48.20％);49.97％were urban children,and 50.03％were rural children.The correct brushing rate was 26.37％;the awareness rate of dental health knowledge was 2.23％;67.88％of children had a correct attitude towards dental health;the prevalence rates of gingival bleeding and dental calculus were 33.69％and 4.62％,respectively.Moreover,42.86％had received pit and fissure sealing treatment.The prevalence of first permanent molar caries among 12-year-old children was 33.69％,with a mean decayed,missing,and filled teeth(DMFT)score of 1.47.Multivariate logistic regression analysis indicated that rural residence(OR=1.38,95％CI:1.20～1.59),daily consumption of carbonated or sugary drinks(OR=1.38,95％CI:1.05～1.82),daily intake of sweets or candies(OR=1.30,95％CI:1.07～1.58),gingival bleeding(OR=0.70,95％CI:0.60～0.81),dental calculus(OR=2.17,95％CI:1.58～2.96),and receiving pit and fissure sealing treatment(OR=0.61,95％CI:0.53～0.70)were factors influencing the prevalence of first permanent molar caries.Conclusion The prevalence of dental caries among 12-year-old children in Chongqing remains high,with low correct brushing and pit and fissure sealing rates.Targeted interventions should be carried out based on the influencing factors,and efforts should be made to expand the coverage of pit and fissure sealing to reduce the caries rate among children.
