Numerical investigation of injection characteristics on normal saline irrigation quality in curved root canals using computational fluid dynamics.

ABSTRACT:

Objectives

The primary aim of this research was to find the effects of Normal saline injection rate and position on irrigation quality in curved root canals.

Methods

Computational Fluid Dynamics (CFD) was used to simulate irrigation in root canals. Root canal geometries were obtained by considering the complete shaping of a rotary file in four root groups with 0, 10, 30, and 60° of curvatures. Fluid surface tension, bouncy, gravity, and air entrance were considered in the numerical simulation using Ansys-CFX software. For each root canal, the flow regime and wall shear stresses were calculated at three different syringe plunger speeds, and three different injection locations of a beveled open-ended needle and their effects on the irrigation quality were investigated in this
