黄埔区学龄前儿童乳牙龋病的防治研究分析

Analysis Study of Prevention and Treatment of Dental Caries of Deciduous Teeth in Preschool Children of Huangpu District

目的 对学龄前儿童进行局部涂氟防龋,预防儿童乳牙龋病的发生;同时与氟化泡沫防龋进行对比观察,了解二者的防龋临床效果.方法 选定两所幼儿园,各随机抽取3～5岁儿童200名,分为对照组和实验组.实验组对儿童进行乳牙局部涂氟防龋（选用多乐氟氟化钠护齿剂）;对照组进行氟化泡沫防龋,对预防乳牙龋病的儿童进行临床观察,干预时间为1年,每半年进行1次防龋治疗.采用SPSS 22.0软件对数据进行统计分析,以龋病发病率和新增龋面作为统计指标.结果 实验组与对照组相比,两组儿童患龋率虽没有明显的下降,但实验组龋面增加较对照组少,两组相比,差异有统计学意义（P＜0.01）.结论 使用局部涂氟与氟化泡沫防龋作用对比,局部涂氟对龋齿增加的控制更有效.

OBJECTIVE To topical fluoride against dental caries of preschool children, to prevent the occurrence of caries in chil- dren, and compare with the fluoride froth, understanding caries clinical effect between. METHODS Selected two kindergartens, 200 children were divided into control group and experimental group, experimental group of deciduous teeth caries of children topical flu- oride（fluoride selection toro）; control group for the fluoride froth, and random sample of 3 -5 year old children each 200, clini- calobservation on prevention of caries, intervention time is one year, caries treatment once every half a year. The data were ana- lyzed by SPSS 22.0 statistical software, tocaries incidence and new DMFS as statistical index. RESULTS In the experimental group compared with the control group, both the rates of caries were not significantly reduced, but the experimental group DMFS increase lower than those in the control group, two groups of DMFS increase compared with statistical significance（P〈0.01）. CONCLUSION The use of topical fluoride and fluoride froth effect contrast, control of topical fluoride on caries increased more effective.
