Abstract
The results of this study indicated that heat-sealed gutta-percha alone and when reinforced with Adaptic or a glass ionomer cement provided the most effective apical seal. It is therefore proposed to expand this study to include these materials and zinc-free Spheraloy and Cupralloy amalgams as retrofilling materials. The amalgams will be used with and without cavity varnish.
摘要
本研究结果表明，单独使用热封牙胶以及用Adaptic或玻璃离子水门汀增强时，能提供最有效的根尖封闭。因此，建议扩大本研究范围，将这些材料以及无锌Spheraloy和Cupralloy汞合金作为倒充填材料纳入研究。汞合金将在有或无洞衬剂的情况下使用。
