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.

Elongation and movement of the gutta-percha master cone during initial lateral condensation.

This study evaluated gutta-percha master cone elongation and apical movement during initial lateral condensation. A split natural tooth model was used. Measurements on photographs taken before and after initial spreading were made. The results showed that both elongation and total cone displacement occur.

Master cone apical behavior under in vitro compaction.

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.
