Preliminary Simulation of the Flow in the Root Canal Using New Irrigation Needle

Abstract

The main purpose of this paper is to explore the possibility of using a new irrigation device to achieve the goals of root canal preparation for endodontic procedures. A secondary goal is to introduce the never before used physical approach of two-phase, two-component irrigation flow in the root canal. Our simulation results show great efficiency of the irrigation procedure in terms of the irrigant volume fraction and wall shear stress at the wall of the root canal over entire working length.
