Neuropsychological and Renal Effects of Dental Amalgam in Children

Abstract

clinicaltrials.gov Identifier: NCT00065988.

Relationship between mercury levels in blood and urine and complaints of chronic mercury toxicity from amalgam restorations

“…22 In a more recent fi ve-year follow-up study examining neurophysiological functions of US children inconsistent differences were found in children with or without amalgam restorations. 23 In an earlier report, the authors Bellinger et al 24 did not find significant differences in adverse neuropsychological or renal effects in children whose caries were restored with dental amalgam compared to those with composite resin. A seven-year follow-up study to assess the safety of Previously diagnosed autoimmune disease was more common in the group with more than 10 amalgams (26.3%), compared with those with 6-10 amalgams (5.6%) or 0-5 amalgams (0%).…”

Scalp hair and urine mercury content of children in the Northeast United States: The New England Children's Amalgam Trial

“…Briefly, the NECAT was a two-arm randomized safety trial designed to compare the neuropsychological and renal function of children whose dental caries were restored using amalgam, with those receiving mercury-free composite restorations (Bellinger et al 2006).…”

“…After completing baseline data collection visits, these 534 children were randomized to a study treatment arm (amalgam or composite), and received standard dental care every 6 months. Over the course of the study, additional dental restorations were placed as clinically indicated, and according to randomized treatment arm assignment (Bellinger et al 2006). All study procedures were reviewed and approved by Institutional Review Boards at NERI and the respective clinical sites.…”

“…The New England Children's Amalgam Trial (NECAT) Bellinger et al 2006) includes 534 children from two sites, rural Maine (predominantly white) and the metro-Boston area, which is racially and ethnically diverse. In addition to measurements of H-Hg and U-Hg at several time points, data are also available for variables including demographics, socioeconomic characteristics, fish consumption, and number of amalgam dental restorations.…”

Jesus tem dentes metal-free no país dos banguelas?: odontologia dos desejos e das vaidades

“…), dando razão e comentando o artigo do médico Ben Goldacre, colunista do jornal britânico The Guardian, que assina a seção Bad Science (Má Ciência), na qual espinafra as muitas lendas sem lastro científico ou empírico que se propagam como vírus pelos meios de comunicação sobre a fama de vilão do amálgama na odontologia (Goldacre, s.d.). Ao partir para a reabilitação do mercúrio utilizado nas antigas restaurações de amálgama, Goldacre observa, e com muita razão, que nenhum meio de comunicação deu destaque ao primeiro estudo publicado (Bellinger et al, 2006) que usou a metodologia, que se diz consagrada pela medicina, baseada em evidência para procurar dirimir a questão. Acessamos a pesquisa de Bellinger et al (2006), da qual participaram 534 crianças de seis a dez anos, atendidas em clínicas dentárias de Boston.…”
