Master core apical movement during compaction: evaluation of two in vitro models.
This study evaluated two in vitro models (a split hard metal model and a split natural tooth model) for the assessment of master cone apical movement. Gutta-percha cones were fitted 0.5 and 1.0 mm short of the apical ends of the artificial canals. Photographs were taken before and after vertical or lateral compaction and measurements were made. The results demonstrated no significant difference between the two models.
