Tatuagem extensa por amálgama em mucosa gêngivo-alveolar

Abstract

Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam tattoo cannot be differentiated from other causes of oral pigmentation, a biopsy should be performed. This article deals with an extensive amalgam tattoo lesion which required a biopsy for a definitive diagnosis. Keywords: Dental amalgam; Mouth mucosa; Pigmentation Resumo: Tatuagens por amálgama são lesões pigmentadas, exógenas, de frequente ocorrência na mucosa bucal, que resultam da introdução acidental de partículas de amálgama nos tecidos moles. O diagnóstico da tatuagem por amálgama é simples, geralmente, baseado em achados clínicos, complementado pela história recente ou pregressa de remoção de restauração por amálgama. Radiografias intraorais podem ser úteis na detecção de radiopacidade, associadas à partícula de amálgama. Nos casos em que as tatuagens por amálgama não permitem diferenciação de outras lesões melanocíticas, o exame histopatológico deve ser realizado. Os autores relatam à ocorrência de lesão extensa por tatuagem de amálgama com confirmação histopatológica.

Clinical Effects of Mercury in Conservative Dentistry: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Controlled Trials

“…e increase of mercury concentrations in breast milk, umbilical cord, and amniotic fluid was found to be statistically significant in the majority of publication reports about this topic [45][46][47][48][49], whereas controversial results have been published regarding the hypothetical influence of dental amalgam on the onset of mental disorders (mainly Parkinson and Alzheimer disease) [50][51][52] and of lichen planus and associated lesions [53][54][55]. Indeed, most of the evidence supporting the thesis of a link between oral mucosal reactions and dental amalgam are based on case reports [56][57][58][59][60][61][62]. Moreover, it has to be reported that some authors published cases of burning mouth syndrome and orofacial granulomatosis arisen in patients previously treated with dental amalgam [63,64].…”
