摘　　要：目的:比较浸润性树脂和窝沟封闭剂治疗早期龋的效果。方法:处理后的前牙置于脱矿液中制备人工龋,之后将人工龋分为4个实验区域,分别应用涂布指甲油、不做任何处理、涂布浸润性树脂、涂布窝沟封闭剂等4种不同的处理方法。再次置于脱矿液中,21 d后,观察脱矿深度。结果:浸润性树脂处理后的牙体第二次脱矿的深度为(4.531±2.163)μm,小于窝沟封闭剂处理过的牙体,其第二次脱矿的深度为(31.228±7.587)μm。结论:浸润性树脂治疗早期龋的效果优于窝沟封闭剂。Objective： To compare the effectiveness of infiltrant method and that of pit and fissure sealant in treating early caries. Methods： We placed the experimental teeth in demineralizing solution to create artificial caries, and we divided it into 4 sections. We applied different methods on these sections including coating nail polisher, infiltrating agents, pit and fissure sealants, and not performing any treatment on the last section in control group. After that, we placed the teeth in demineralizing solution for an extra 21 days. At last, we observed the depth of artificial caries. Results： sealing effects of infiltrating agent showed better outcome than pit and fissure sealant. And The depth of the second demineralization treated with infiltrating resin was （4.531±2.163）μm, which was lower than that of the teeth treated with pit and fissure sealant（31.228±7.587）μm. Conclusion： Infiltrant is better than the pit and fissure sealant for the treatment of early caries.
