Abstract

The effect of Chloroform, Xylene and Halothane on Enamel and Dentin microhardness of human teeth was studied in this in-vitro study. A total of 60 specimens — 30 specimens on Enamel and 30 specimens on Dentin were studied. Equal number of teeth were treated with Xylene, Chloroform, Halothane and with 0.3% Phosphoric acid as positive control and Saline as the negative control. A Vicker’s microhardness test was carried out on the specimens. A significant decrease in Enamel and Dentin microhardness was found in all the solvent treated groups. The amount of decrease in microhardness was directly related to the exposure time.
