Amalgam tattoo - A case report

Abstract

Amalgam Tattoo is an iatrogenic entity defined as a bluish black or grey lesion of the oral mucous membrane caused by accidental implantation of silver amalgam into the tissue during tooth restoration or extraction. According to Stedman’s medical dictionary 2nd edition Amalgam Tattoo is defined as “A bluish black or grey lesion of the oral mucous membrane caused by accidental implantation of silver amalgam into the tissue during tooth restoration or extraction.” A 35 year old male patient reported to the Department of Conservative Dentistry & Endodontics with the complaint of discoloration of upper front tooth since 5-6 years. On examination tooth was found non vital and there was blackish discoloration of attached gingiva in relation to the same tooth, measuring around 0.5 x 0.5 cm in diameter with pus discharge in relation to the same. A periodontal pocket measuring 7 mm was present in relation to mesial surface of 11. Radiographically a radiopacity was observed in relation to apex of 11 suggestive of retrograde filling. Radiolucency was also seen around this suggestive of periapical abscess. Empty pulp canal space and an intact palatal surface was seen in relation to 11 indicating that no root canal treatment was done. Regenerative procedures were carried out along with Periapical Curettage and Root end resection. This is an iatrogenic case which is being handled by interdisciplinary approach. The case was diagnosed as chronic periapical abscess with amalgam tattoo.
