Modeling Dentinal Fluid Flow Using Analytical and Numerical Methods

Project Overview

This project develops analytical and numerical models to characterize fluid flow inside dentinal tubules and quantify pressure-driven transport within microscale dental structures. We model the physical properties of dentin, the tubule geometry, and the resulting flow dynamics under a range of boundary conditions. Using computational fluid dynamics (CFD), we solve the governing equations to capture how fluid velocity, pressure gradients, and transport behavior evolve within the tubule network. The analysis also incorporates the chemical interaction between the irrigant and dentin, allowing us to examine how material dissolution alters tubule morphology and subsequently affects fluid transport. Through mathematical derivations, numerical solution techniques, and systematic parameter exploration, this work provides a quantitative framework for understanding dentinal fluid dynamics and the coupling between chemical reactions and fluid flow. This modeling approach supports broader applications in dental biomechanics and the study of biological material behavior.
