Dental amalgam use has been controversial ever since the Crawcour brothers of France introduced amalgam to the United States in 1833. It has been criticized for its alleged clinical shortcomings and biologic effects. As a result, we thought that it would be useful to provide an update on dental amalgam in two parts. Part I, presented here, focuses on the clinical aspects of dental amalgam, whereas Part II will focus on dental amalgam's biologic effects.

Development of Functional and Hydrolytically Stable Vinyl Monomers as Methacrylate Dental Resin Restorative Alternatives.

Dental resin-based restorative (RBR) materials represent the most ubiquitous biomaterials utilized globally. Methacrylate (MA)-ester based monomers - present in RBRs since the 1960s - experience significantly elevated rates of failure compared to previously used silver/amalgam fillings attributed to their hydrolysis reported in both simulated and in vivo environments. There is currently no alternative RBR chemistry that matches the functional and clinical workflow considerations of MA-RBRs while addressing their limited-service lives.

Purpose: This study was performed to evaluate the expression of beam hardening artifacts generated by high atomic number materials in stitched cone-beam computed tomography (CBCT) images, compared to the traditional acquisition mode.
Materials And Methods: CBCT volumes were acquired using an acrylic resin phantom embedded with pairs of cylinders made from amalgam dental alloy, cobalt-chromium alloy, gutta-percha, titanium, and zirconium. These cylinders were placed within the overlapping zones of the stitching reconstruction area.

Dental professionals who handle dental amalgam are at risk of mercury exposure, though the prevalence and severity of elevated mercury levels from non-occupational sources are not well characterized. We report two dental workers who had elevated urinary mercury levels (37 and 25.6 mcg/L) during routine health screenings.

The placement of root filling materials aims to prevent the occurrence of post-treatment apical periodontitis following completion of endodontic treatment. Materials should possess properties that will not permit bacterial invasion and infection, namely excellent sealing ability and/or antibacterial properties. In root-end filling procedures or repair of root perforations, the root filling materials are placed in a particularly challenging clinical environment, as they interface with a relatively large area with the periradicular tissues.

Methods: Secondary descriptive and statistical analyses were performed on data from 2 previous studies. The data consisted of responses to questionnaires on teaching policies and the proportion of posterior restorations (amalgam and composite resin) performed in Canadian and US dental schools.
