Analysis Of Caries Prevalence And Intervention For Kindergarten Children In Jiangwan Community In Shanghai

ObjectiveTo investigate the status of dental caries of children in kindergartens in Jiangwan district, and the relation with some behavioral risk factors, and to analyse the effect of interventions, and then provide implications.MethodsThis is a community intervention research. On one hand, a general survey of dental caries of children in kindergartens in Jiangwan district was conducted; one the other hand, an intervention study was conducted in two kindergartens in Jiangwan district, among which Fengzhen kindergarten was the intervention group and Baiyulan kindergarten was the control group, and qualitative study and quantitative study method were used to analyse the behavioral risk factors and the present situation of interventions implementation.Results(1)The situation of dental caries and caries filling of children in all kindergartens in Jiangwan district:in2011, dental caries rate and filling caries rate were44.93%and20.40%respectively, and the number of caried teeth was averaged at2.03; in2012, dental caries rate and filling caries rate were45.15%and26.25%respectively, and the number of caried teeth was averaged at1.39. The dental caries rate increased with the growth of age, and that in migrants was higher than that in residents. The filling caries rate in migrants was higher than that in residents.(2)Before intervention, the survey results in Fengzhen kindergarten and Baiyulan kindergarten:both dental caries rate and caries filling rate in showed no significant difference between two kindergartens (P>0.05). There were no statistical differences in children’s oral hygiene habits, parents’ oral hygiene habits, parents’knowledge attitude and behavior of dental caries, and teachers’ knowledge attitude and behavior of dental caries between two kindergartens (P>0.05).(3)After intervention, the survey results in Fengzhen kindergarten and Baiyulan kindergarten:dental caries rate in Fengzhen kindergarten was lower than that in Baiyulan kindergarten, while caries filling rate in Fengzhen kindergarten was higher than that in Baiyulan kindergarten, and there was statistical significance (P<0.05). There were statistical differences in children’s oral hygiene habits, parents’ oral hygiene habits, parents’ knowledge attitude and behavior of dental caries, and teachers’ knowledge attitude and behavior of dental caries between two kindergartens (P<0.05).(4)The survey results in Fengzhen kindergarten (the intervention group) before and after intervention implementation:there was no statistical difference in dental caries rate between before intervention and after intervention, while caries filling rate after intervention was higher than before intervention (P<0.05). After intervention, children’s oral hygiene habits (postprandial gargle, brushing, number of brushing, brushing time, etc.), parents’ knowledge attitude and behavior of dental caries, and teachers’ knowledge attitude and behavior of dental caries were better than before intervention (P<0.05), while there was no statistical difference in parents’oral hygiene habits between before intervention and after intervention (P>0.05).(5)The survey results in Baiyulan kindergarten (the control group) before and after intervention implementation:after intervention, both dental caries rate and caries filling rate were higher than before intervention (P<0.05). There were no statistical differences in children’s oral hygiene habits, parents’ oral hygiene habits, parents’ knowledge attitude and behavior of dental caries, and teachers’ knowledge attitude and behavior of dental caries between two kindergartens between before intervention and after intervention (P>0.05).Conclusions (1)In kindergartens, the dental caries rate was high while the caries filling rate was relatively low.(2)Children in migrants were the population at high risk for dental caries.(3)There were many risk factors of behavior for children in kindergartens, but but can be prevented and controlled.(4) The prevention and control work required the coordination of the hospital, the school and the parents.Suggestions(1) Organization of child health care should strengthen the monitoring work of dental caries of children in kindergartens, and got associated with the dental clinics, and organize specialists to enhance dental health in regular span of time.(2)Community hospitals should strengthen the oral health knowledge training for the teachers in kindergartens and parents.(3)The intervention object of dental caries related measures should be extened into family menbers.
