Abstract

This Study represents an attempt to investigate histologically the effect of metallic
mercury vapor on the developing rat teeth after inhalation by pregnant rats .
In this study albino – wistar rats were used and divided into control and
experimental groups.
The control group consisted of 8 pregnant rats, and the experimental group
consisted of 12 pregnant rats. Then 20 born rats from the control group and 20 born
rats 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 and

experimental group when compared to that of the control group .
