Part 3 Biomechanics in endodontics (Article Series), Effect of the endodontic post used on the dentine, soft vs stiffer material, novel approach via numerical model, Stupid models for interpreting living organs

Key Points

• The aim is to examine how the choice of endodontic post affects the mechanical properties of dentine.
• Introduced various mechanical aspects of treated teeth
• Compared performance of fiber and metallic posts
• Utilized numerical modeling for analysis
• Found that living dentine shows different fatigue life compared to dead dentine
• Demonstrated that the choice of post influences dentine stiffening ability
• Highlighted the need for better understanding of dentine dynamics
