摘要：

背景：传统方法玻璃离子作为封闭剂耐磨性能差，抗折强度低，位于合面的封闭剂很容易脱落，很难取代树脂封闭剂。
目的：观察光固化树脂封闭剂和非创伤性充填技术玻璃离子窝沟封闭幼儿乳牙的效果。
方法：按同人半口随机比较的方法，对89名3岁幼儿的左或右半口符合窝沟封闭条件的乳磨牙在非创伤性充填技术下行玻璃离子窝沟封闭，对侧半口符合窝沟封闭条件的乳磨牙进行树脂封闭。
结果与结论：窝沟封闭后6，18个月玻璃离子组封闭物脱落率均低于树脂材料组(P < 0.05)。玻璃离子材料最易脱落的牙位是下颌第二乳磨牙；树脂材料最易脱落的牙位是上颌第二乳磨牙。封闭后6个月，玻璃离子组封闭的乳牙患龋率低于树脂材料组，18个月时两组间差异无显著性意义。说明非创伤性充填技术玻璃离子窝沟封闭幼儿乳牙的脱落率低，操作简单，防龋效果肯定，且成本低，在经济学上可行性优于树脂封闭。

Abstract:

BACKGROUND: Traditional glass ion sealant has a poor abradability and a low rupture strength. The sealant on the occlusal surfaces easily fell off, and is difficult to replace resin sealant.
OBJECTIVE: To observe the effects of traditional resin sealant and atraumatic restorative treatment (ART) glass ionomer-based pit and fissure sealant for the young children.
METHODS: Randomized comparison method was used to compare ART glass ionomer-based pit on molars of one side with resin sealant on the opposite side in 89 3-year-old children.
RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were significantly lower than those of resin sealant (P < 0.05). The caducous position of ART gliass ionomer sealant was the second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The secondary caries rate of ART glass ionomer sealant was significantly lower than that of resin sealant at 6 months. No significant difference was determined between groups at 18 months. These suggest that ART glass ionomer pit and fissure sealant has lower drop-out rate, simple operation and low cost with excellent caries-preventing effect. Since it is economically superior to resin sealant, the method is worth popularizing in caries-preventing projects.
