| Objects:To study the caries status of permanent teeth in 12-year-old children in Sichuan Province,to explore the related factors affecting the risk of caries in children,and to find out the differences in caries status among 12-year-old children in Sichuan Province with different characteristics,so as to put forward effective measures and policy suggestions for reducing the risk of caries in children.Methods:The stratified cluster random sampling method was used to comprehensively consider the geographical location,economic conditions and other factors.Eight counties(cities,districts)were randomly selected in Sichuan Province,and the survey points were randomly selected.A total of 2077 children were investigated for oral health status,oral examination and questionnaire survey.Excel 2019 was used to input data.SPSS 26.0 and SAS 9.4 were used to analyze the influencing factors of children’s caries.Theχ~2 test was used to compare the count data,and the t test or variance analysis was used to compare the measurement data.Multivariate logistic regression analysis was used.The test level was set asα=0.05 except for special instructions.Results:A total of 2077 12-year-old children in Sichuan province and some parents of children who had undergone clinical examination were investigated by health knowledge questionnaire.The survey results show that:1.The results of children’s oral hygiene knowledge are as follows.The correct rates of health knowledge of"gingival bleeding is normal when brushing","bacteria can cause gum inflammation","bacteria can cause gum caries","bacteria can cause caries","fluoride can cause caries","fluoride can not protect teeth","pit and fissure sealing can protect teeth"and"oral diseases may affect the general health"are 60.71%,79.92%,71.40%,72.89%,78.14%,45.98%,34.23%and 71.83%.Among them,there were statistically significant differences between urban and rural areas in"fluoride is not effective in protecting teeth","dental sealant can protect teeth"and"oral diseases may affect the health of the whole body";there were statistically significant differences between female students and male students in"bacteria can cause dental caries"(73.49%).2.The proportion of children agreeing that"oral health is important to their lives"is94.32%;the proportion of children agreeing that"regular oral examination is necessary"is 85.41%;the proportion of children agreeing that"tooth quality is inherently not related to their own protection"is 84.16%;the proportion of girls is higher than boys;the proportion of children agreeing that"prevention of dental disease depends on themselves first"is 91.53%;the proportion of children in rural areas is higher than that in urban areas.3.51.61%of children have never been involved in dental treatment;20.10%of 12-year-old children in Sichuan province who have dental treatment have been involved in prevention;36.02%have been involved in treatment;33.63%have been involved in consultation and examination;520(25.04%)have been sent regularly to the hospital for dental examination,and 1557(74.96%)have not been sent regularly to the hospital for dental examination;and among children who have not been sent regularly to the hospital for dental examination,10.40%are afraid of going to the hospital,and 24.53%are afraid of going to the hospital,and 57.80%are not aware of the need for periodical examination.4.Among 2077 12-year-olds in some areas of Sichuan Province,the caries prevalence rate of permanent teeth was 33.51%,and the classification of urban and rural areas was based on the place of residence.The caries prevalence rate of urban children was 33.16%,and the caries prevalence rate of rural children was 33.94%,with no statistical significance.The caries prevalence rate of girls was higher than that of boys,the caries prevalence rate of permanent teeth was 38.69%,the caries prevalence rate of boys was 28.91%,with statistical significance.The caries prevalence rate of children was3.98%,and the caries supplement rate of urban children was 3.93%,and the caries supplement rate of rural children was 4.04%,with no statistical significance.The caries prevalence rate of girls was higher than that of boys,with 4.82%and 2.72%respectively,with statistical significance.The caries prevalence rate of permanent teeth was 0.77,the caries rate of girls were 0.97,and the caries rate of boys were 0.60,with a statistical significance.5.Of the 1602 teeth of 2077 12-year-old children with caries in Sichuan Province,the highest caries rate was found in the first permanent molar of the right mandible and the first permanent molar of the left mandible.The number of decayed teeth was 244 and245 respectively,which was 23.54%of the total number.The number of decayed teeth decreased with the increase from 3 to 17.Mean significant caries index Si C was 2.29.6.Single factor analysis showed that the possible influencing factors of caries of 12-year-old children in Sichuan province were brushing or not,eating before going to bed,taking xylitol and chewing gum,protein food,calcium supplement frequency,condition of deciduous teeth and accommodation(P<0.05).The possible influencing factors of caries in 12-year-old male children in Sichuan province were brushing or not,xylitol chewing gum,protein intake,calcium supplement frequency,sweet drink and deciduous tooth status(P<0.05).The possible influencing factors of caries in 12-year-old female children in Sichuan province were food consumption before sleep,accommodation and deciduous tooth status(P<0.05).7.Multivariate analysis showed that the possible influencing factors of caries in 12-year-old children in Sichuan province were sex,brushing,residing and deciduous teeth.The possible influencing factors of caries in 12-year-old male children in Sichuan province were brushing or not and sweet drink.The possible influencing factors of caries in 12-year-old female children in Sichuan province were food consumption before bedtime,accommodation and deciduous tooth status.Conclusion:The oral health attitude of 12-year-old children in Sichuan Province is positive,and more than 80%of children have a correct understanding of oral health.Children have the willingness to learn relevant oral health knowledge,but the actual oral health behavior results show that the overall oral health of children in Sichuan is still at a low level.2.More than half of the children had no relevant oral medical treatment behavior,and most of the children who did not have regular oral examination thought that there was no need for examination and did not know that the oral cavity needed regular examination.The incidence of dental caries in 12-year-old children in Sichuan Province is high.The results of this study showed that the caries prevalence rate of 12-year-old children in Sichuan Province(33.51%)was higher than 25%proposed in the"Healthy China 2030"plan outline,and the caries filling ratio was low.Local governments and health departments should strengthen health education for children and parents who are susceptible to dental caries.Schools and communities should regularly carry out oral health surveys and assessments to reduce the risk of dental caries in children and improve their oral health.The risk of caries in 12-year-old children in Sichuan Province is affected by many factors,such as gender,tooth brushing,schooling,and caries status of deciduous teeth.Combined with this survey,in the prevention and control of dental caries in children,it should be treated according to different people. |
