本研究的目的是比较玻璃离子封闭剂(富士Triage)和树脂封闭剂(Clinpro)在6-9岁儿童中的固位和防龋性。这项裂口随机临床试验覆盖了35名儿童/140颗长出的永久第一磨牙。在6个月、12个月和18个月后，由两名独立的检查者进行评估，并将数据与儿童龋病风险和年龄组进行比较。采用Kaplan-Meier生存方法和卡方检验进行统计学分析。玻璃离子封闭剂和树脂封闭剂在部分封闭剂和完全保留封闭剂的存活率以及无龋窝沟存活率方面没有统计学上的显著差异。在固位力方面，两种封闭剂在研究结束时在较年轻的年龄组中表现得更好，并且在中等龋齿风险的儿童中显示出更好的防龋性。18个月后，两种封闭剂在6-9岁儿童中具有类似的固位和防龋效果。
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.
