摘要：

背景：以往报道的玻璃离子封闭剂耐磨性能差，抗折强度低，合面封闭剂很容易脱落。
目的：观察在非创伤性充填技术下高强度玻璃离子应用于幼儿乳牙窝沟封闭的效果。
方法：按自身对照的方法，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作空白对照。
结果与结论：非创伤性充填技术下窝沟封闭后6，18个月，玻璃离子完整保留率为94.15%及77.72%。6个月时牙位脱落率：下颌第二乳磨牙>下颌第一乳磨牙>上颌第二乳磨牙>上颌第一乳磨牙，18个月时牙位脱落率：下颌第二乳磨牙>上颌第二乳磨牙>下颌第一乳磨牙>上颌第一乳磨牙。非创伤性充填技术下玻璃离子封闭的乳牙患龋率远低于未作封闭的乳牙，6，18个月时差异均有显著性意义(P < 0.01)。提示非创伤性充填技术下高强度玻璃离子窝沟封闭在幼儿乳牙中的脱落率低，操作简单，防龋效果肯定。

Abstract:

BACKGROUND: It has been reported that glass ionomer sealants have a poor wear resistance and low rupture strength that are easy to fall off on the occlusal surfaces.
OBJECTIVE: To observe the effects of high-strength glass ionomer via the atraumatic restorative treatment (ART) on the pit and fissure of deciduous teeth in the young children.
METHODS: A self-controlled method was used to compare ART glass ionomer-based pit and fissure seal on unilateral molars with resin sealant on the contralateral side in 89 children aged 3 years.
RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were 94.15% and 77.72%, respectively. At 6 months after treatment, ART gliass ionomer sealant was more caducous in mandibular second deciduous molars > mandibular first deciduous molars > maxillary second deciduous molars > maxillary first deciduous molars; at 18 months after treatment, the rank was mandibular second deciduous molars > maxillary second deciduous molars > mandibular first deciduous molars > maxillary first deciduous molars. 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 caries prevalence rate of the deciduous teeth treated with ART glass ionomer sealant was significantly lower than that without sealant at 6 and 18 months (P < 0.01). These findings indicate that ART glass ionomer pit and fissure sealant is of a lower drop-out rate, easy to operate and of low cost with excellent caries-preventing effect.
