Dental Amalgam Restorations and Children’s Neuropsychological Function: The New England Children’s Amalgam Trial
BACKGROUND A concern persists that children's exposure to mercury vapor from dental amalgams produces neurotoxicity. OBJECTIVE Our goal was to compare the neuropsychological function of children, without prior exposure to dental amalgam, whose caries were repaired using either dental amalgam or mercury-free composite materials. METHODS We conducted a randomized controlled trial involving 53...
متن کاملDental Amalgam Exposure and Urinary Mercury Levels in Children: The New England Children’s Amalgam Trial
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...
متن کاملRenal Effects of Dental Amalgam in Children: The New England Children’s Amalgam Trial
BACKGROUND Mercury is nephrotoxic and dental amalgam is a source of mercury exposure. METHODS Children 6-10 years of age (n = 534) with two or more posterior teeth with caries but no prior amalgam restorations, were randomized to one of two treatments--amalgam or resin composite (white fillings)--used for caries treatment during 5 years of follow-up. The primary outcome was change in IQ, but ...
متن کاملWear of dental amalgam.
The wear of cental amalgam was studied by single- and double-pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...
متن کاملMicrostructure of dental amalgam.
Numerous studies have been done in the past to identify the phases present in dental amalgam. Both metallographic and X-ray diffraction techniques have been used.-' Most researchers now presume that dental amalgam consists mainly of three phases. The original particle is an alloy of Ag, Sn, Cu, and sometimes Zn; the major portion is the compound Ag3Sn, which is often referred to as Py. After am...
