introduction: prefabricated metal and ceramic posts can be used with different kinds of core materials as an alternative to the conventional casting post and cores. it is unclear how these post and core systems can withstand different kind of forces in the mouth. the purpose of this study was to compare the fracture strength of endodontically treated, crowned maxillary incisors restored with ca...

introduction: tonsillectomy is one of the most common surgeries in the world and the most common problem is post-tonsillectomy pain and bleeding. the relief of postoperative pain helps increase early food intake and prevent secondary dehydration. one method for relieving pain is peritonsillar injection of epinephrine along with an anesthetic, which has been shown to produce variable results in ...

in this paper, we used a shape matching algorithm to recognize farsi digits. for each sampled point on the contour of a shape, we obtain a descriptor showing the distribution of the other points of the contour, with respect to this point. based on these descriptors, we find the corresponding points of the two contours and take the sum of their distances as a dissimilarity measure between two sh...

introduction: many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. the aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method. materials and methods: nine blocks of psm-5 photoelastic material with 45×45×10 mm dimen...
