objective: the main goal of this study was to evaluate stress distribution of endodonti-cally treated maxillary central incisors restored with glass fiber posts, composite resin cores, and crowns with different ferrule designs. materials and methods: four three-dimensional models of a maxillary central incisor were modeled in solidworks 2006. tooth with no ferrule, tooth with a 2 mm circumferen...

AIM Core buildup composite resins with prefabricated posts are commonly used to restore endodontically treated teeth. This study compared the sealing ability of Core Max II and Panavia F2.0 cement with total-etch and self-etch adhesive systems. METHODS AND MATERIALS Sixty recently extracted human second premolar teeth were chosen and their crowns were cut 3 mm above the CEJ. After preparing p...

Recent work has shown the value of using unsatisfiable cores to guide maximum satisfiability algorithms (Max-SAT) running on industrial instances [5,9,10,11]. We take this concept and generalize it, applying it to the problem of finding minimal correction sets (MCSes), which themselves are generalizations of Max-SAT solutions. With the technique’s success in Max-SAT for industrial instances, ou...

purpose: to compare orbscan ii and pentacam keratometry readings in terms of their agreement with a manual javal type keratometer methods: in this retrospective study, records of patients who had refractive surgery were reviewed. we extracted data of 765 eyes which had keratometry with the javal keratometer of these, 577 had orbscan ii and 200 eyes had pentacam acquisitions. minimum (min-k) and...
