Using the appropriate modulus of elasticity of periodontal ligament matters in stress analysis of human first premolar tooth and periodontium structures

Abstract Although the modulus of elasticity of the human periodontal ligament (EPDL) values used in dentistry widely ranged from 0.01 to 175 MPa, the exact EPDL value has not been determined. This study aimed to verify whether and how EPDL values affect the stress distribution over the tooth and per...
