Analysis Of The Deciduous Dental Caries Risk Factors Of 3~5 Year-old Children In Ningxia

Objective:To analysis of the deciduous dental caries risk factors of 3-5 year-old children in Ningxia,so as to provide epidemiological foundation for the prevention of dentalcaries.Methods: According to 2952 children aged 3-5 years old in Ningxia area of caries disease status investigation results for sampling,used cases-controlled research method,take 3~4 age children’s decayed-missing-filled teeth(dmft) ≥ 4 and 5 age dmft≥ 6 into high caries group(that cases group),dmft=0as controlled group,by national,gender,age,area for pairing,on two groups children’s parents for questionnaire investigation.Using the SPSS18.0 statistical software package for statistical analysis of the data.Results: 1. General situation of children:parent education,whether the only child,source of drinking water,the proportion who completed the questionnaire were no significant differences between the case group and control group(P>0.05).Primarily by his mother to take care of daily life and monthly family income of more than 3000 RMB who can not susceptible deciduous caries,there was a significant difference between case group and control group(P <0.05).2. Diet:case group had a higher frequency of sugar intake, the difference between the two groups was significant(P<0.05).3. Mother’s pregnancy and childbirth:sick mother during pregnancy,premature children is the difference between the two groups was significant(P<0.05),but no significant differences in birth weight between the two groups(P>0.05).4. Prevalence of infants:oral health and general health assessment of the child’s parents, the difference between the two groups was significant(P<0.05), while the 3-year-old child is suffering from systemic disease was not statistically significant(P>0.05).5.Feeding situation:milk sugar,previously had to sleep with a bottle or nipple mother habits and sweet intake before sleep difference between the two groups was significant(P<0.05),feeding patterns was not statistically significant(P>0.05).6. Oral health conditions: whether parents supervise or help kids brush their teeth,the age of starting tooth-brushing and brushing frequency in age between the two groups was significant(P<0.05);whether use of fluoride toothpaste was no significant(P>0.05).7. Parents’ oral health knowledge:deciduous teeth broken without treatment,good or bad is born,and their protection have little relationship, mother bad teeth can affect a child’s teeth difference between the two groups was significant(P<0.05),The pit and fissure sealant can prevent children dental caries,oral health is very important, first of all on their own,the protection of preventive dental age six teeth is very important,ever heard of fluoride toothpaste was no significant(P>0.05).8.Medical behavior:dental treatment needs of children in case group caused by its proportion of the dentistis significantly higher than the control group, in the past year, whether the child had a toothache, toothache last processing method,the last to see the pitch now how long children between the two groups was not statistically significant(P> 0.05).9. Logistic regression analysis showed:oral health assessment, sweet intake before sleep,higher frequency of sugar intake,previously had to sleep with a bottle or nipple mother habits and the age of starting tooth-brushing is relation to dental caries of deciduous teeth.Conclusion:1. Premature children,higher frequency of sugar intake,additionofsugar in milk,previously had to sleep with a bottle or nipple mother habits, sweet intake before sleep the children susceptible deciduous caries,that is a risk factor deciduous caries.2.Primarily by his mother to take care of daily life and Monthly family income of more than 3000 RMB,start brushing earlier age,parents supervise or help kids brush their teeth,parents have good oral health knowledge that children are not susceptible to caries in primary teeth,is the protective factor.3.Logistic regression analysis showed:sweet intake before sleep,higher frequency of sugar intake,previously had to sleep with a bottle or nipple mother habits and the age of starting tooth-brushing is relation to dental caries of deciduous teeth are high risk factors of caries.Start brushing earlier age is a protective factor.
