[Chlorhexidine as a root canal irrigant--antimicrobial and scanning electron microscopic evaluation].

Introduction: Selection of irrigant is very important for long-term success of root canal therapy.

Objective: This study was undertaken to evaluate the antimicrobial effects of 2% chlorhexidine digluconate solution (CHX) against five selected microorganisms and to evaluate its efficacy in root canal cleaning.

Methods: In this study, by agar diffusion test, were evaluated antimicrobial effects of three root canal irrigants: 5.
