The effect of household chemicals on deciduous and permanent tooth class

Abstract

Dental anthropology was wide ranging implications for the field of anthropology. Teeth have become important sources of data about the individual as well as possibly being able to identify them. One problem that can arise is the chemical destruction of teeth whether it be diagenesis in an archaeological context or deliberately in a forensic context. In terms of deliberate destruction of the body several household chemicals are cheap and easily assessable. The purpose of this research is to look at how six household chemicals affect both deciduous and permanent tooth classes. The six chemicals include, Vinegar (acetic acid), Bleach (sodium hypochlorite), Biz (Sodium per carbonate), Lye (Sodium Hydroxide) Ammonia and the control (tap water). The teeth were placed in jars containing the chemical for twenty-four hours. Every hour the weight and mesial/distal length were measured. Of the six chemicals, vinegar affected the teeth the most.
