  Objectives: 1. To evaluate the velocity, pressure, and force in the root canal system during LAI. 2. To explore the application of numerical simulation analysis in root canal therapy studies. Materials and methods: A simplified model of laser-activated irrigation (LAI) was established. The volume of fluid (VOF) model was used to solve the Navier-Stokes equation and standard k-ε turbulent model was used as turbulent model. The axial maximum velocity and axial force at 1 mm, 4 mm, and 16 mm away from apex, as well as the pressure at apex in10 000-time steps were calculated. Results: The peak pressure and axial force increased with laser energy. At 1 and 4 mm away from apex, the axial maximum velocity increased with laser energy below 35 mJ, and slightly decreased from 35 mJ to 50 mJ. Conclus.. Read More»
