The results of this study indicate that proper amalgam removal and, in some cases, removal of all the other metals and replacement with biocompatible composites can eliminate or reduce 80% of the classic symptoms of chronic mercury poisoning. These results also show that the strength of an individual’s serum-globulin reaction, to many metals used in dentistry, especially the five metals present...

AIM To estimate the quantity of dental amalgam that Ontario dentists release into waste water. METHODS Information from a self-administered postal survey of Ontario dentists was combined with the results of other experiments on the weight of amalgam restorations and the quantity of amalgam waste that bypasses solids separators in dental offices. Algorithms were developed to compute the quanti...

OBJECTIVES To determine contact allergies in patients with oral lichen planus and to monitor the effect of partial or complete replacement of amalgam fillings following a positive patch test reaction to ammoniated mercury, metallic mercury, or amalgam. DESIGN In group A (20 patients), the oral lesions were confined to areas in close contact with amalgam fillings. In group B (20 patients), the...

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

BACKGROUND Urinary mercury (U-Hg) excretion is a commonly used biomarker for mercury exposure from dental amalgam restorations. OBJECTIVES Our goal was to determine the most efficient measure of dental amalgam exposure for use in analyses concerning U-Hg in children. METHODS We analyzed time-sensitive longitudinal amalgam exposure data in children randomized to amalgam restorations (n = 267...
