Introduction: This study investigated the effects from the carious cavity and access from it on the fracture resistance of endodontically treated maxillary premolars using finite element analysis (FEA). Methods: A maxillary premolar was used to compare three types of access cavity related to having a proximal carious defect: Caries-driven access (CDA), Conservative access that has a mesial component (MCA) as well as traditional access with the same mesial component (MTA). Cyclic loading was simulated on the occlusal surface and number of cycles till failure (NCF) was compared to the intact tooth model (IT). Mathematical analysis was done to evaluate the …
