Models were subjected to three different loads. The highest stress distribution was observed on the enamel surface of the Cd-EC design and the dentin surface of the TEC-II. The stress was mainly concentrated on the lingual root surfaces and in the pericervical area. Enlarging the access cavity significantly increased stress distribution on enamel and dentin.eninfo:eu-repo/semantics/closedAccessCaries-driven access cavityendodontic access cavityFinite element analysismandibular molartruss cavityArticle10.1080/10255842.2025.2457124Q3WOS:0014095732000012-s2.0-8521668862439881450Q2
