Dental Amalgam Exposure and Urinary Mercury Levels in Children: The New England Children’s Amalgam Trial

open access: yesEnvironmental Health Perspectives, 2008
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 ...

Fracture toughness, diametrical strength, and fractography of amalgam and of amalgam to amalgam bonds

Dental Materials, 1993
Chevron-notch fracture toughness, diametrical tensile strength and fractography were evaluated for bulk amalgams and for bonds formed between new and 1-day-old amalgams of the same type. Three types of bonded specimens were prepared: 1) by mechanically roughening the 1-day-old amalgam with 600-grit paper; 2) using a new mercury-rich amalgam; and 3 ...

Interface corrosion in amalgam-to-amalgam and amalgam-to-nonprecious metal crown couplings

The Journal of Prosthetic Dentistry, 1986
This study examined the contact surface area in the coupling of a class II amalgam restoration with another class II amalgam restoration or with a stainless steel or nickel-chrome crown in 1% NaCl solution. The characterization of interfaces was carried out by using SEM and EDX microanalysis.

On Amalgam Toxicity

International Journal of Technology Assessment in Health Care, 1990
Toxicity implies an adverse effect. It may be caused by an overdose of any substance or combination of substances, either by an initial high dose or by the accumulation of a toxic substance over a long period of time. Thus, toxicity is dose dependent. It is also a relative term in that therisk involved must be evaluated and the available alternatives ...

Amalgamation of Ortholattices

Order, 1997
Let \(K\) be a class of algebras of the same type. \(K\) is said to have the (strong) amalgamation property (S)AP if the following holds: If \(B,L_1,L_2\) are algebras in \(K\) and if, for \(i=1,2\), \(\varphi_i\) is an embedding of \(B\) into \(L_i\) then there exist an algebra \(C\) in \(K\) and, for \(i=1,2\), an embedding \(\psi_i\) of \(L_i\) into
