Influence of volume of endodontic irrigants used in different irrigation techniques on root canal dentin microhardness.

Introduction: Overzealous application of endodontic irrigants affects the root canal dentin mechanical properties. The effect of volume of endodontic irrigants on the microhardness of root canal dentin has not been studied.

Aim: This study assessed the effect of volume of endodontic irrigants used in different final irrigation activation techniques on root canal dentin microhardness (RCDM).
