Overview

Finite element analysis evaluates stress and strain in teeth with cavities, highlighting structural risks.

Key Points

  • The aim is to understand how cavity size affects stress and strain distribution in teeth.
  • Conducted finite element analysis on three tooth models (intact, conservative cavity, extensive cavity)
  • Applied a 565 N occlusal load in simulations
  • Utilized nonparametric statistical tests (Kruskal–Wallis and Mann–Whitney) for data analysis
  • Maximum stress increased significantly with cavity size: 96.18 MPa (intact) to 185.32 MPa (extensive)
  • Maximum strain capacity was highest in the intact tooth (0.007503) and lowest in prepared teeth
  • Cavity preparation amplifies localized stress and reduces overall tooth flexibility
