To compare the impact of fifth- and seventh-generation bonding agents on the microleakage between Embrace WetBond sealants and Ionoseal.
Forty extracted human premolar teeth were used for the study and grouped according to different sealants and bonding agents-group I: Embrace WetBond sealant with fifth-generation bonding agent; group II: Embrace WetBond sealant with seventh-generation bonding agent; group III: Ionoseal with fifth-generation bonding agent; group IV: Ionoseal with seventh-generation bonding agent. For microleakage evaluation, all the teeth were subjected to invasive sealant placement using the respective sealant materials in combination with bonding agents as specified. The treated teeth were stored at 37°C for 24 hours and then thermocycled for 100 cycles at temperatures of 5°C and 55°C with a dwell time of 30 seconds. In order to assess microleakage, the samples were immersed in 0.2% methylene blue dye for 24 hours, then sectioned in buccolingual direction, and evaluated under stereomicroscope.
The mean microleakage scores in group III were highest at 0.90 ± 0.57, while the least was in group IV at 0.30 ± 0.68, indicating that Ionoseal with seventh-generation bonding agent was the most effective. However, when the mean microleakage scores of the four groups were compared using Kruskal-Wallis test, it indicated that the differences were not statistically significant.

比较第五代和第七代粘结剂对Embrace WetBond封闭剂与Ionoseal之间微渗漏的影响。
本研究使用了40颗拔除的人类前磨牙，并根据不同的封闭剂和粘结剂进行分组——第一组：Embrace WetBond封闭剂搭配第五代粘结剂；第二组：Embrace WetBond封闭剂搭配第七代粘结剂；第三组：Ionoseal搭配第五代粘结剂；第四组：Ionoseal搭配第七代粘结剂。为了评估微渗漏情况，所有牙齿均按照规定使用各自的封闭剂材料与粘结剂组合进行侵入性封闭剂放置。处理后的牙齿在37°C下储存24小时，然后在5°C和55°C的温度下进行100次热循环，每次停留时间为30秒。为了评估微渗漏，将样本浸入0.2%的亚甲蓝染料中24小时，然后沿颊舌方向切片，并在体视显微镜下进行评估。
第三组的平均微渗漏评分为0.90±0.57，最高，而第四组最低，为0.30±0.68，这表明搭配第七代粘结剂的Ionoseal最有效。然而，当使用Kruskal-Wallis检验比较四组的平均微渗漏评分时，结果表明差异无统计学意义。
