Abstract

The invention described herein provides for a simple, economical system and method for reducing environmental release of dental amalgamous mercury from teeth caused by cremation of corpses. The invention controls and reduces the amount of mercury released using a pre-crematorial and non-disfiguring system and method. The system of the invention can include a dental containment and applicator delivery system to apply a curable thermal protectant composition onto the teeth. The composition coating significantly inhibits the extent of thermal destruction of the tooth per se including its amalgam filling content.
