<br/><br/> Purpose: The aim of this study was to compare the fracture resistance of endodontically treated teeth with interrupted ferrule using two types of post core systems. Materials and methods: Forty extracted human maxillary central incisors were decoronated 2mm to the proximal cement-enamel junction and endodontically treated. Teeth were divided into two groups according to the type of restorative material (n=20), and then each group was subdivided Cast into four subgroups according to the ferrule continuity (n=5)
