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.
