| Objective:To investigate and analyse the influence of parental education level on caries status,caries reasons,parents’ oral health knowledge in children aged 0-3,and to provide evidence for effective prevention of early childhood caries according to parental education level.Methods:One university community and one non-university community in Taiyuan were selected randomly.350(university community)and 389(non-university community)children aged 0-3 were vaccinated from October 2019 to October 2020 for oral examination and questionnaire survey.The oral examination was performed in a knee-to-knee position,under natural light,with a plane oral mirror and No.5 probe.Oral health behaviors of children and their parents were investigated with self-made questionnaire.SPSS 26.0 software was used for statistical analysis.χ2 test was used to compare the prevalence of caries among children in two communities,and χ2 test and logistic regression analysis were used to analysis the risk factors of caries among children.P<0.05 was considered statistically significant.Results:1.Caries statusA total of 739 children aged 0-3 were selected and the prevalence of caries was39.65%.There are 350 children in the university community,the prevalence of caries was28.57%,the mean dft score was 1.42,the treatment rate was 4.11%.There are 389 children in the non-university community,the prevalence of caries was 49.61%,the mean dft score was 2.34,the treatment rate was 2.29%.The prevalence of caries among children in university community was significantly lower than non-university community,and the difference was statistically significant(P < 0.05).There were statistically significant differences in the prevalence of caries among children of the same sex in two communities(P<0.05).With the increase of age,the prevalence of caries in two communities increased gradually.2.Analysis of Influencing Factors of CariesThe independent risk factors of caries among children in university community were never seen a dentist(OR=1.721,95%CI:1.618 ～ 4.840,P < 0.05)、 high sugar intake(OR=5.429,95%CI:2.482 ～ 11.874,P < 0.05)、 less brushing time(OR=1.732,95%CI:1.065 ～ 2.816,P < 0.05)、 non-fluorinated(OR = 1.426,95%CI:1.195 ～3.933,P < 0.05).The independent risk factors of caries among children in non-university community were Sharing tableware with parents(OR=1.440,95%CI:1.241 ～ 3.804,P <0.05)、high frequency of sweet food consumption(OR = 2.199,95%CI:1.497 ～ 3.229,P <0.05)、less brushing time(OR = 1.592,95%CI:1.117 ～ 2.270,P < 0.05)、no using fluoride toothpaste(OR = 2.084,95%CI:1.333 ～ 3.257,P < 0.05).3.Analysis of Oral Health Knowledge of ParentsOnly 2% of parents in both communities believed that oral care should start right after birth.And even about 40% of parents never gave oral care to their children and don‘t have clear awareness of oral care for children.Conclusion:1.A survey of dental caries in two communities showed that:1)The prevalence of caries in children aged 0-3 in Taiyuan was high and the treatment rate was low;2)The prevalence of caries in children aged 0-3 increased with age.3)Parental education level was an influential factor of caries in early childhood.2.A survey of risk factors for dental caries in two communities showed that:1)The risk factors of caries in children with different parental education levels were different.2)It is necessary for the communities to carry out targeted oral healthy education according to the parents’ educational level.3.Analysis of oral health knowledge of parents in the two communities showed that:1)Parents‘ oral health knowledge was very weak;2)Oral health education during pregnancy in the community is essential. |
