摘要
本研究将含绿茶多酚涂膜（0.078g/L）用于乳牙，观察其对乳牙的防龋作用，并分析其作用特点。实验组107名儿童的第一乳磨牙和乳中切牙涂布绿茶多酚涂膜，隔6个月后重复涂布一次，一年后复查患龋情况，记录dmft和dmfs。另110名儿童作为对照。结果涂布牙新患龋率与对照组相比下降66％；实验组非涂布牙新患间牙、新患龋牙面和新患龋率均显著低于对照组；绿茶多酚涂膜对后牙防龋作用大于前牙；从不同牙面看，涂膜对面作用最强，颊舌面次之，近远中面较小。表明绿茶多酚涂膜对涂布牙和口腔中其它非涂布牙具有显著防龋作用。
The aim of the present research is observing the effects of tea polyphenol varnish on caries prevention. 1O7 children were in treated group, their first deciduous molars anddeciduous incisors were treated by tea polyphenol varnish twice each. Other 110 children incontrol group did not receive any treatment. Two doctors examined their dental caries andrecorded dmft and dmfs before treated and one year after treatment. The results indicate thatthe new caries incidence of the first deciduous molars and deciduous incisors in treatmentgroup decreased 66% than that in control group. The results show that the new caries incidence of other untreated teeth in treated group is lower significantly than that in controlgroup. The effects of tea polyphenol varnish on preventing caries were more significant in deciduous molar than in deciduous incisor. The results also indicate that the effect of varnish isstronger in occlusal surface, and less in medial and distal surfaces of teeth.
