Comparison of the retention of 5 core materials supported by a dental post.

Purpose: This study evaluated the retention of dental post heads (No. 2 Flexi-Post) embedded in 5 core materials (1 automix resin composite, 2 hand-mixed resin composites, and 2 glass ionomers).

Materials And Methods: Samples were prepared by embedding post heads in 4.

Morphological measurements of anatomic landmarks in pulp chambers of human maxillary furcated bicuspids.

The aim of this in vitro study was to measure key morphological features of pulp chambers from furcated maxillary bicuspid teeth. There were 107 random human maxillary bicuspid teeth used. Each bicuspid was radiographed using the Trophy RVG digital imaging system and a Belmont Acuray X-ray at 70 kVp.
