西藏普兰县学龄期儿童龋齿发病情况及与体质指数的相关性

Incidence of dental caries among school-age children in Pulan County,Tibet region and its correlation with body mass index

目的分析西藏普兰县学龄期儿童的口腔健康状况及与发育情况的关系。方法对在西藏普兰县进行学籍注册的529名藏族中小学生(男300名,女229名)进行龋病检查、测量身高、体重等身体参数,分析其患龋率、龋均、失牙发生率及龋齿充填率等口腔健康指标,并采用Spearman相关性分析研究龋失补数与体质指数(BMI)的关系。结果普兰县学龄期儿童整体患龋率高达75.99%,但6~8岁年龄组患龋率(64.38%)明显低于9~11岁、12~14岁年龄组(82.82%、79.61%)(P<0.05);龋均为3.18,且9~11岁年龄组龋均(4.14)高于6~8岁(2.42)、12~14岁年龄组(3.01),男生龋均(3.44)高于女生(2.83);18.53%的学龄期儿童存在因龋导致牙齿缺失的情况,且男生失牙发生率(22.00%)明显高于女生(13.97%)(P<0.05);该群体的龋齿充填率仅为0.30%;Spearman相关性分析结果显示,其龋失补数与BMI呈负相关关系(r=-0.272,P<0.01)。结论西藏普兰县学龄期儿童患龋率明显高于全国平均水平,但治疗率极低,并且由于口腔健康状况不佳,对该地区儿童的生长发育也造成了一定程度的负面影响。

Objective To investigate the oral health status of school-age children in Pulan County,Tibet region,and to analyze the relationship between their growth and oral health.Methods A total of 529 Tibetan primary and middle school students(300 males and 229 females)registered in Pulan County,were examined for caries and their height,weight and other physical parameters were measured.The oral health indicators such as caries prevalence,caries mean,tooth loss rate and dental caries filling rate were analyzed,and the relationship between DMFs and body mass index(BMI)was studied by Spearman correlation analysis.Results The overall prevalence of caries of school-age children was as high as 75.99%,but the caries prevalence of 6-8 years old group(64.38%)was significantly lower than that of 9-11 years old group(82.82%)and 12-14 years old group(79.61%)(P<0.05);the caries mean was 3.18,and the caries mean of 9-11 years old group(4.14)was higher than that of 6-8 years old group(2.42)and 12-14 years old group(3.01),and the caries mean of boys(3.44)was higher than that of girls(2.83);18.53%of school-age children had tooth loss due to caries,and the incidence of tooth loss in boys(22.00%)was significantly higher than that in girls(13.97%)(P<0.05);the dental caries filling rate of this group was only 0.30%.Spearman correlation analysis showed that the DMFs was negatively correlated with body mass index(BMI)(r=-0.272,P<0.01).Conclusions The prevalence of caries in school-age children in Pulan County,Tibet region is significantly higher than the national average,but the treatment rate is extremely low.The poor oral health has a certain degree of negative impact on the growth and development of the children in this area.
