Coronal microleakage of five materials used to create an intracoronal seal in endodontically treated teeth.
The purpose of this study was to quantitatively compare the sealing effectiveness of five restorative materials that were used to create an intracoronal double seal. Fifty-two extracted mandibular molars were randomly divided into five groups of 10 teeth, and one positive and one negative control tooth. The crowns were removed and the pulpal floor and canal orifices were sealed with 3 mm of one...

15 صفحه اولStress Distribution in Four Restorative Methods in Endodontically Treated Maxillary Premolar: A 3D Finite Element Analysis
Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...
