Compare and evaluate the microleakage of different types of pit and fissure sealants, 3M ESPE Clinpro, GC Fuji Triage Capsule, and 3M ESPE Filtek Z350 XT.
A total of 54 freshly extracted maxillary and mandibular premolar teeth were used and randomly divided into three groups of 18 teeth each, and the following pit and fissure sealants were used: group I-Clinpro, group II-GC Fuji Triage Capsule, and group III-Filtek Z350 XT. Samples underwent thermocycling at 5° and 55°C with a dwell time of 10 seconds for 250 cycles. The apices of the teeth were sealed with impression compound, and two coats of fingernail polish were applied and immersed in 5% methylene blue dye for 24 hours and then sectioned. The sectioned specimens were then analyzed at 4× magnification under a stereomicroscope for dye penetration and were evaluated based on Williams and Winters' criteria.
The data were collected for statistical analysis. Descriptive statistics included mean, standard deviation (SD), frequency, and percentage. Inferential statistics included the Chi-squared test and one-way analysis of variance (ANOVA), followed by the Tukey's test. The level of significance was set at 0.05 at a 95% confidence interval, and the results revealed that the mean difference of the sealants was GC Fuji Triage (2.1667), Clinpro (0.7778), and Filtek Z350 XT (0.1667).
Filtek Z350 XT exhibited the least microleakage when compared to Clinpro and GC Fuji Triage, with their mean difference statistically significant. Hence, Filtek Z350 XT can be a promising sealant and a restorative material.

比较和评估不同类型的窝沟封闭剂(3M ESPE Clinpro、GC Fuji Triage Capsule和3M ESPE Filtek Z350 XT)的微渗漏情况。
共使用54颗新鲜拔除的上颌和下颌前磨牙,随机分为三组,每组18颗牙,并使用以下窝沟封闭剂:第一组-Clinpro,第二组-GC Fuji Triage Capsule,第三组-Filtek Z350 XT。样本在5℃和55℃下进行热循环,保持时间为10秒,循环250次。用印模膏封闭牙根尖,涂两层指甲油,浸入5%亚甲蓝染料中24小时,然后切片。然后在体视显微镜下以4倍放大率分析切片标本的染料渗透情况,并根据威廉姆斯和温特斯标准进行评估。
收集数据进行统计分析。描述性统计包括均值、标准差(SD)、频率和百分比。推断性统计包括卡方检验和单因素方差分析(ANOVA),随后进行Tukey检验。显著性水平设定为95%置信区间下的0.05,结果显示封闭剂的平均差异为GC Fuji Triage(2.1667)、Clinpro(0.7778)和Filtek Z350 XT(0.1667)。
与Clinpro和GC Fuji Triage相比,Filtek Z350 XT表现出最小的微渗漏情况,其平均差异具有统计学意义。因此,Filtek Z350 XT可能是一种有前景的封闭剂和修复材料。
