An Epidemiological Investigation Of Oral Health In 6?12 Year-old Pupils In Zhongwei,Ningxia And Relevant Factors Analysis On 12 Year-old Children

Objective To understand the Oral Health of children aged from 6 to12 by making Oral health examination in Zhongwei,including the caries prevalence?filling treatment and gingivitis prevalence?dental calculus detection rate;To analysis the related influencing factors of dental caries and gingivitis on 12 year old children's questionnaire survey,to provide epidemiological basis for children's oral health care in Zhongwei.Methods Applying The Third National Oral Health Epidemiological Survey scheme,methods by using random cluster sampling.Extracting 1823 Hui and Han children from 3 area(Shapotou area?Zhongning county?Haiyuan county)in Zhongwei,making oral health examination?filling the checklist,and oral questionnaire survey on children 12 years old.The results were analyzed using SPSS 17.0 software package.Results The ratio of caries was 47.43%,and the average number of caries teeth was 1.48 among 1823 subjects in Zhongwei.The filling rate of the total caries was 5.74%.The prevalence of dental caries were statistically no significant difference in 3 areas,the caries mean dmft score were three region difference was statistically significant,Shapotou's was lower than other two countrys,the difference was statistically significant.The filling rate of the total caries in Shapotou was higher than Haiyuan,it has significant difference.There was no significant difference between Hui and Han children on dental caries and average caries.There was also no significant difference between male and femal e on dental caries and average caries.The average caries differences between different age groups have statistical significance.The prevalence of gingivitis among 1823 of 6-12 years old children was 48.00%,the difference of gingivitis prevalence in Shapotou area?Zhongning county?Haiyuan country was statistically significant.There was no significant difference between Hui and Han children in the prevalence of gingivitis and the dental calculus detection rate.The prevalence of gingivitis and dental calculus detection rate of male and female have significant difference.The prevalence of gingivitis and dental calculus detection rate differences between different age groups have no statistical significance.Correlation factors analysis of dental caries and gingivitis on12year-old children: When the dental caries was taken as the dependent variable and the total 4 factors as brushing frequency ? frequency of eating bread/cake/biscuit?oral health examination?using fluoride toothpaste in single variable analysis taken as independent variable,the results from a multivariate logistic regression model showed that the frequency of eating bread/cake/biscuit and oral health examination are important factors affecting children tooth decay occurs.Only brushing frequency is important factors affecting children gingivitis by single factor analysis.Conclusion 1.The rate of caries of aged from 6-12 years old in Zhongwei was high,and filling rate was very low.There was no significant difference between Hui and Han children on dental caries and average caries,there was also no significant difference between male and female children on dental caries and average caries,the average caries differences between different age groups have statistical significance.2.The incidence of gingivitis in Zhongwei aged from 6-12 years old children were at the mid-level.There was no significant difference between Hui and Han children on prevalence of gingivitis,but has significant difference between male and female children.The prevalence of gingivitis differences between different age groups have no statistical significance.3.The result from single factor analysis and multiple-factor analysis showed:brushing frequency is important factors affecting children gingivitis,the frequency of eating bread/cake/biscuit and oral health examination are important factors affecting children tooth decay occurs.4.Children in Zhongwei have poor oral hygiene habits,and weak in oral health care knowledge,to reduce the occurrence of oraldisease,we should strengthen children's oral health knowledge,cultivate children good oral health routine.
