The purpose of this study was to examine microleakage of two root-end-filling materials with and without the use of bonding agents. For microleakage measurement a fluid transport model was used. Sixty single-rooted teeth were used in this study. They were prepared with step-back technique and then an apicoectomy was performed. Then the teeth were divided into four groups. Group A were filled with Fuji II LC glass-ionomer cement, group B were filled with Fuji II LC and a new bonding agent, Fuji Bond, group C were filled with Admira composite resin, and group D were filled with Admira and Admira Bond, a new bonding agent. At 24 h, 1 month, and 2 months after filling the leakage along these filling materials was determined under a low pressure of 0.1 atm. At all experimental times, glass-ionomer groups showed significantly less microleakage than resins groups. Between Admira and Admira Bond groups, significantly less leakage was observed in the root sections with Admira Bond at 24 h.
本研究的目的是检测两种根尖充填材料在使用和不使用粘结剂情况下的微渗漏情况。采用液体传输模型测量微渗漏。本研究使用了60颗单根牙。采用逐步后退技术进行预备，然后进行根尖切除术。然后将牙齿分为四组。A组用富士II LC玻璃离子水门汀充填，B组用富士II LC和一种新型粘结剂富士Bond充填，C组用Admira复合树脂充填，D组用Admira和一种新型粘结剂Admira Bond充填。充填后24小时、1个月和2个月时，在0.1个大气压的低压下测定沿这些充填材料的渗漏情况。在所有实验时间点，玻璃离子水门汀组的微渗漏均显著少于树脂组。在Admira组和Admira Bond组之间，充填后24小时时，使用Admira Bond的牙根部分渗漏显著较少。
