The objective of this study was to compare the retention and caries-preventive effect of glass ionomer (Fuji Triage) and resin-based (Clinpro) sealants among 6-9-year-old children. This split-mouth, randomized clinical trial covered 35 children/140 fully erupted permanent first molars. Evaluation was conducted by two independent examiners after 6, 12, and 18 months and the data were compared in relation to the children's caries risk and age groups. The Kaplan-Meier survival method and chi-square test were used for analysis. There were no statistically significant differences in the survival of partial and fully retained sealants or in the survival of caries-free pits and fissures between glass-ionomer and resin-based sealants. In terms of retention, both sealants performed better in the younger age group at the end of the study, and showed better caries prevention in moderate caries risk children. After 18 months, both sealants had comparable retention and caries-preventive effects in 6-9-year old children.
本研究的目的是比较玻璃离子（Fuji Triage）和树脂基（Clinpro）封闭剂在6至9岁儿童中的保留率和防龋效果。这项双侧、随机临床试验涵盖了35名儿童/140颗完全萌出的恒牙第一磨牙。由两名独立检查者在6个月、12个月和18个月后进行评估，并根据儿童的龋病风险和年龄组对数据进行比较。采用Kaplan-Meier生存法和卡方检验进行分析。玻璃离子封闭剂和树脂基封闭剂在部分保留和完全保留封闭剂的存留率或无龋窝沟的存留率方面均无统计学显著差异。在保留率方面，两种封闭剂在研究结束时在较年轻年龄组中的表现更好，并且在中度龋病风险儿童中显示出更好的防龋效果。18个月后，两种封闭剂在6至9岁儿童中的保留率和防龋效果相当。
