title: The apical seal via the retrosurgical approach. I.A. preliminary study.
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.
