To clinically evaluate the retention rates and caries-prevention effect of a resin-based, non-etch and rinse, self-etch primed pit and fissure sealant containing Sealant Pre-reacted Glass Ionomer Cement (S-PRG) fillers, in comparison to a conventional resin-based sealant over an 18-month period.
There were 81 children, aged 6-12 years old, who were randomly assigned to one of two sealant-groups, either the self-etch primed sealant (Beautisealant, Shofu) or the conventional etch and rinse sealant (Seal it, Spident). A total of 218 sealants of both groups were placed on first permanent molars with either sound surfaces (The International Caries Detection and Assessment System [ICDAS], code 0) or incipient enamel caries lesions (ICDAS code 1) according to the manufacturers' instructions. Each sealant restoration was independently evaluated in terms of retention and caries status at 6, 12 and 18 months. The data were statistically analysed with the Chi-squared test and z-test and the level of significance was preset at α = 0.05.
The differences between the complete retention rates of the two sealant groups were statistically significant in all periods of evaluation (p < 0.01). Survival rates of each sealant-group were comparable on sound (ICDAS 0) and enamel caries lesions (ICDAS1). Caries prevention effect of the two sealant groups was similar at the end of the evaluation period.
The clinical performance of the S-PRG filler-containing dental sealant placed with a self-etching primer was poor regarding its retention. Its significantly higher loss did not lead to more carious occlusal surfaces at the 18-month recall.
与传统树脂基窝沟封闭剂相比，临床评估含预反应玻璃离子粘固粉（S-PRG）填料的树脂基、免酸蚀冲洗、自酸蚀底漆窝沟封闭剂在18个月期间的保留率和防龋效果。
81名6至12岁儿童被随机分配到两种封闭剂组之一，即自酸蚀底漆封闭剂（Beautisealant，松风）或传统酸蚀冲洗封闭剂（Seal it，斯派登）。根据制造商的说明，在第一恒磨牙的健康表面（国际龋病检测与评估系统[ICDAS]，代码0）或早期釉质龋损（ICDAS代码1）上总共放置了两组的218颗封闭剂。在6、12和18个月时，对每个封闭剂修复体的保留情况和龋病状态进行独立评估。数据采用卡方检验和z检验进行统计学分析，显著性水平预先设定为α = 0.05。
在所有评估期间，两种封闭剂组的完全保留率差异具有统计学意义（p < 0.01）。在健康（ICDAS 0）和釉质龋损（ICDAS1）上，每个封闭剂组的生存率相当。在评估期结束时，两种封闭剂组的防龋效果相似。
含S-PRG填料的牙科封闭剂与自酸蚀底漆一起使用时，其保留性能较差。在18个月的回访中，其显著更高的脱落率并未导致更多的龋坏咬合面。
