Electron microscopic study on the effect of diode laser and some irrigants on root canal dentinal wall

Abstract EN

This study was carried out to determine the effect of diode laser and some irrigants such as sodium hypochlorite and hydrogen peroxide on surface morphology of the root canal dentinal wall by using Scanning Electron Microscope.

Forty extracted single rooted teeth with fully developed apices were used and divided equally into four groups: Group I: Irrigated with distilled water (control group).

Group II: Irrigated with Sodium hypochlorite.

Group III: Irrigated with Hydrogen peroxide.

Group IV: Treated with Diode laser irradiation.

The results showed that, laser irradiation removed debris and the smear layer that resulted from root canal preparation better than sodium hypochlorite and hydrogen peroxide.

It also obliterates the dentinal tubule orifices and the dentin surface appeared glazed.
