BACKGROUND No documentation in the literature about taper of cast posts. This study was conducted to measure the degree of cast posts taper, and to evaluate its suitability based on the anatomy aspects of the common candidate teeth for post reconstruction. METHODS Working casts for cast posts, prepared using Gates Glidden drills, were collected. Impressions of post spaces were made using poly...

The judicious post endodontic restoration of the tooth afterwards accomplishment management, is just as bossy for effective cure teeth with striking structural disfigurement as, eminence rehabilitation. pivotal objective to retain core that ropes/pulleys absolute prosthesis. When there diminutive structure left, a and also encouragements in augmenting fracture confrontation after root canal man...

Background/Aim. The cause of discolored gingiva (DG) is the presence metal in gingival tissue. DG a relatively common case, and caused by deposition amalgam material tissue during dental application or oral surgery. aim this study was to determine significance cast post for appearance abutment teeth (AT) relation type fixed prosthesis (FDP) alloy. Methods. included 327 subjects with FDP. A tota...

Purpose. To analyze the stress distribution in an endodontically treated maxillary central incisor restored with various post-core systems and assess the benefit of ferrule using finite element analysis. Material and Methods. Twelve models with metal ceramic crown were created based on the combination of three types of post-core systems (titanium post-composite resin core, nickel-chromium post-...

Data clustering methods have been proven to be a successful data mining technique in the analysis of gene expression data. The Cluster affinity search technique (CAST) developed by Ben-Dor, et. al., 1999, which has been shown to cluster gene expression data well, has two drawbacks. First, the algorithm uses a fixed initial threshold value to start the clustering. As stated in the original paper...
