Influence Of Fluoride Foam Combined With Oral Health Education On Prevention Of Caries In Children In Handan

Objectives To explore the oral health status of 3?5 years-old children in Handan city;Trying to identify some rist factors related to Severe Early Childhood Caries,And provide scientific evidence from preventive medical direction.To observe the effect of caries prevention with fluoride foam combined with oral hygiene education,and the effect of caries prevention with fluoride foam in outpatient department and to explore that whether it is meaningful.Methods Based on the methods of multiple stratified and whole cluster randomized sanpling,was used to selected 372 3?5 years old preschoolers and oral health status was examined and recorded.The parents of children who with SECC were investigated by oral questionnaire,including feeding,diet,oral hygiene habits and so on.Children aged 3?5 years old who take part in clinical trial were divided into group of use fluorinated foam by group and on outpatient department.Those who did not take park in with the group were taken as control group,once every forth months to applicate fluoride foam for a period of one and a half years.Epidata3.1 was adopted to establish the dababase,employing SPSS 21.0 analysis,t-test chi-square test,single variable analysis and Logistic regression were separately carried on the statistical analysis.The test level is 0.05 for both sides.Results 1 The prevalence of caries was 69.35% of preschool children in Handan,the mean DMFT(decayed,missing and filled teeth)value was 3.95±3.90;The prevalence of caries was 55.32%,75.65%,80.17% of 3,4,5 years old children,and the difference was significant;207 children suffering from SECC,the prevalence of caries was 55.65%.And the SECC prevalence of caries of 3,4,5 years old children were 44.68%,53.04%,71.55%,the difference was significant;Significant Caries Index children'mean DMFT was 8.61 ±2.53,non Significant Caries Index in mean DMFT was 1.63±1.33,the difference was significant;The DI-S of 3?5 children was 1.15 ±0.71,and the DI-S of 3,4 years old were significantly lower than 5 years old children.The prevalence of abnormal occlusion was 40.05%.The prevalence of black stain was 11.29%.2 taking caries free and SECC as dependent variables,taking 13 factors with single factor analysis into multiple factors analysis,risk factors of SECC include the older the age of brushing the teeth,intake before bedtime,and the higher DI-S is the risk factor of SECC,abnormal occlusion is positive correlation with SECC disease,and frequent postprandial gargle,the higher the education of parents is,and the black stain is the protective factor of SECC.3 At the end of the observation,the new incidence of cares,SECC and the mean dmft of outpatient department group,collective group and the control group is increase inturn.Among which the incidence of caries in the group of outpatient department group was lower than that in the control group(P < 0.05).The incidence of SECC in the outpatient department group was lower than that in the collective group and the control group,the difference was significant,and the caries incidence rate in the outpatient department group was lower than that in the collective group and the control group.The effect of oral hygiene education is not significant.Conclusions 1 the prevalence of caries and SECC in preschool children in Handan City was very high,and the prevalence of caries in children of lower age was also very high.However,filling rate was very low.2 Effective dental care for the risk factors of caries during the period of the garden is of great significance in reducing the prevalence of dental caries and SECC.Health care institutions should improve the awareness of oral care and oral health skills of parents and child-care institutions through a variety of ways.3 The use of fluorinated foam on a regular basis can reduce the incidence of dental caries in preschool children.Oral hygiene education alone is not effective in preventing caries,so it is necessary to reduce the incidence of dental caries with clinical preventive measures.The incidence of SECC can be effectively reduced by fluorine coating on the outpatient department,and the effect of caries prevention is better than that of the traditional collective fluorine coating method.
