目的

探讨不同黏接系统应用于乳牙复合体修复后,对边缘密闭性、操作时间、操作复杂程度的影响。

方法

乳磨牙牙冠制备成薄片,表面制备Ⅰ类洞。分别应用黏接系统Single Bond、XenoⅢ、iBond,模拟临床操作,记录时间。温度循环法模拟体内状况处理样本后,扫描电镜观察,并行染料渗透实验。单盲法对二维微渗漏情况进行观察。

结果

黏接系统iBond 的边缘密闭性方面明显差于XenoⅢ与Single Bond 黏接系统(P <0.05)。XenoⅢ黏接系统操作时间明显少于Single Bond 与iBond 黏接系统(P <0.05)。

结论

自酸蚀黏接系统XenoⅢ能取得与全酸蚀黏接系统Single Bond 相同的密闭性,同时缩短操作时间、减少操作的刺激性,自酸蚀黏接系统iBond 边缘密闭性差,操作复杂、时间长。

Objective

To evaluate the marginal sealing potential, manipulation time and complexity of compomer restorative material with different adhesive systems used in primary teeth.

Methods

ClassⅠcavities were prepared in primary molar.Teeth were divided into 3 groups to simulate clinical restoration with three adhesive systems: Single Bond, Xeno Ⅲ and iBond.Manipulation time was recorded.After thermocycle (500 cycles between 5℃~55℃with 15-second dwell time), specimens were observed by electron microscope (SEM) and dye infiltration were performed on them.The thicknesses of adhesive resin were measured and marginal integrity was evaluated.

Results

The marginal sealing of the iBond group is significantly poorer than that of the other 2 groups (P <0.05).The manipulation time of XenoⅢgroup is significantly shorter than that of the other 2 groups (P <0.05).

Conclusions

The marginal sealing potential of the selfetching adhesive system, XenoⅢ, is close to all-etching system, Single bond.In addition, the operation time and stimulus can also be reduced.The self-etching system, iBond demonstrates poorer marginal-sealing, longer manipulation time and higher complex.It is not recommended to use the iBond adhesive system in pediatric dentistry.
