目的了解景宁畲族自治县学龄前儿童乳牙龋齿现况及影响因素,为制定学龄前儿童龋齿预防措施提供依据。方法采用整群抽样方法,选取景宁畲族自治县城区8所幼儿园2 107名3~6岁儿童进行问卷调查和口腔检查,计算患龋率,并比较不同生活行为对患龋率的影响。结果 2 107名儿童乳牙患龋率为80.87%,3岁组儿童患龋率为68.79%,6岁组儿童患龋率高达87.24%,乳牙患龋率随年龄增长呈升高趋势(P<0.05)。父母有龋齿的儿童患龋率为83.73%,高于父母无龋齿儿童的72.23%(P<0.05)。吃甜食、喝碳酸饮料频率增加、开始刷牙年龄延迟,儿童患龋率呈上升趋势(P<0.05);刷牙方式不正确的儿童患龋率为83.16%,高于刷牙方式正确儿童的78.97%(P<0.05)。结论景宁畲族自治县学龄前儿童乳牙患龋率较高,应针对饮食、刷牙等行为采取预防措施。
Objective To understand the status and influencing factors of deciduous teeth of pre-school children in Jingning She Autonomous County, and to provide evidence for the prevention of dental caries in preschool children. Methods A total of 2 107 children aged 3 ~ 6 years old from 8 kindergartens in Jingning She Autonomous County were selected for questionnaire and oral examination. The caries prevalence was calculated and the effect of different life behaviors on caries prevalence was compared. Results The prevalence of dental caries in 2 107 children was 80.87%, that of children in 3 years old was 68.79%, that of children in 6 years old was 87.24%, and the caries prevalence of deciduous teeth increased with age (P <0.05) ). The caries prevalence rate of children with dental caries was 83.73%, which was higher than 72.23% (P <0.05) of caries-free children. The frequency of eating sweets and drinking carbonated drinks increased, and the age of brushing started was delayed, and the prevalence of caries was on the rise (P <0.05). The prevalence of dental caries was 83.16%, higher than 78.97% of the children P <0.05). Conclusion There is a high prevalence of deciduous teeth in preschool children in Jingning She Autonomous County. Preventive measures should be taken in the aspects of diet and brushing.
