title: Master cone apical behavior under in vitro compaction.
abstract: This study first evaluated the fitting of two brands of gutta-percha points 0.5 and 1.0 mm short of the apical end of an artificial canal. Photographs were taken before and after vertical or lateral compaction and measurements were made. Warm gutta-percha compaction was associated with greater apical cone movement than lateral condensation. Total apical cone movement was not related to the distance the master cone was initially adapted from the apical opening.
