Dental educators' attitudes towards the teaching of dental amalgam.

Objective: To ascertain dental educators' attitudes towards the teaching of dental amalgam at dental schools in Australia and identify preferred curricular approaches in a potentially "amalgamless" profession.

Methods: A mixed methods analysis was employed based on an open-ended response survey followed by a closed-ended questionnaire. Identification of key issues from the survey helped frame the questionnaire.

The effect of working time on the displacement of Biodentine beneath prefabricated stainless steel crown: a laboratory study.

Objective: To investigate the displacement of Biodentine following cementation of stainless steel crowns (SSC) with glass-ionomer cement (GIC) on plastic deciduous teeth prepared for pulpotomy.

Methods: Twenty plastic teeth with prepared occlusal cavities were divided into four groups and had Biodentine placed as a mock pulpotomy agent. The pulp chamber was filled with freshly mixed Biodentine then a GIC-loaded SSC was seated on the tooth using a standardized seating force for periods of: 1 min (Group 1); 2 min (Group 2), 3 min (Group 3) and 6 min (Group 4) after mixing.

Calcium silicate-based cements: composition, properties, and clinical applications.

Mineral trioxide aggregate (MTA) is a calcium silicate-based cement (CSC) commonly used in endodontic procedures involving pulpal regeneration and hard tissue repair, such as pulp capping, pulpotomy, apexogenesis, apexification, perforation repair, and root-end filling. Despite the superior laboratory and clinical performance of MTA in comparison with previous endodontic repair cements, such as Ca(OH) , MTA has poor handling properties and a long setting time. New CSC have been commercially launched and marketed to overcome the limitations of MTA.

Push-out bond strength of CPP-ACP-modified calcium silicate-based cements.

This study evaluated the push-out bond strength of 0%, 0.5%, 1.0%, 2.

Fracture force of cantilevered zirconia frameworks: an in vitro study.

Statement Of Problem: Little evidence is available showing the effect of connector dimension and cantilever length on the ultimate fracture force of computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia implant frameworks.

Purpose: The purpose of the study was to determine the impact of variations in the cross-sectional dimension of connector sites and variations in the effective cantilever length (load point) on zirconia implant frameworks. This would allow verification of the fracture force with 2 proposed mathematical models.
