A comparative scanning electron microscope investigation of cleanliness of root canals using hand k-flexofiles, rotary race and k3 instruments.

Introduction: The most important aims of root canal preparation are the removal of vital pulp tissue, remaining necrotic debris and infected dentin, eliminating the bulk of bacteria present in the root canal system. The aim of this study was to compare the cleaning efficacy of hand K-Flexofiles and rotary RaCe and K3 instruments in root canal preparation.

Materials And Methods: A total of 60 single rooted teeth with maximum curvature of <20º were selected and divided into three groups of 20 teeth each.
