Effects of Prenatal metallic mercury vapor exposure on the developing teeth of rats

Abstract

This Study represents an attempt to investigate histologically the effect of metallicmercury vapor on the developing rat teeth after inhalation by pregnant rats .In this study albino – wistar rats were used and divided into control andexperimental groups.The control group consisted of 8 pregnant rats, and the experimental groupconsisted of 12 pregnant rats. Then 20 born rats from the control group and 20 bornrats from the experimental group were selected to be sacrificed at the ages of (3&13)days.The specimens were prepared for processing and staining with haematoxylin andeosin, and examined under light microscope.Results showed no histological abnormalities in the dental tissue of theexperimental group when compared to that of the control group .This Study represents an attempt to investigate histologically the effect of metallicmercury vapor on the developing rat teeth after inhalation by pregnant rats .In this study albino – wistar rats were used and divided into control andexperimental groups.The control group consisted of 8 pregnant rats, and the experimental groupconsisted of 12 pregnant rats.
