摘要
目的:研究乳牙龋活跃程度对氟离子导入防龋效果的影响.方法:采用整群随机抽样方法,抽取张家港市12所幼儿园的1743名3~4岁儿童,根据基线口腔检查的龋失补牙数(dmft),分为无龋组(dmft=0)、低龋组(1≤dmft<4)、高龋组(dmft≥4),接受定期口腔健康指导的同时进行1年两次的氟离子导入,两年后比较3组儿童的新增dmft.结果:两年后无龋组、低龋组、高龋组新增dmft分别为0.82±1.39、2.11±2.15、2.41±2.10,3组间有统计学差异(F=135.58,P<0.05),两两相比差异均有统计学意义(P<0.05).结论:高龋活跃程度可降低氟离子导入的防龋效果,在乳牙未患龋之前进行干预效果最好.
Abstract
AIM:To evaluate the influence of caries activity on the caries preventive effect of fluoride ion infiltration.METHODS:1,743 children aged 3-4 year-old from 12 preschools in Zhangjiagang were selected with cluster random sampling method.They were divided into caries-free group (dmft=0),low caries group (1≤dmft<4) and high caries group (dmft≥4) according to the dmft calculated by the first oral examination.The children were given regular oral health education and a bi-annual fluoride ion infiltration application.The increase of dmft was compared among the 3 groups at 2-year follow-up.RESULTS:The increase of dmft in carie-free group,low caries group and high caries group was 0.82 ±1.39,2.11 ±2.15,and 2.41 ±2.10,respectively (F=135.58,P<0.05;between every 2 groups,P<0.05).CONCLUSION:The high caries activity may weaken the preventive effect of fluoride ion infiltration.The optimal timing of intervention is before caries development.
