The restoration of broken down puIpless molar teeth generally implies the provision of a cast post and core with a crown. In this research the failure resistance of some restoration methods utilizing amalgam was investigated under an oblique load. The results suggest that intracoronal reinforcement with a prefabricated dowel did not significantly increase the in vitro resistance. It is expected...

A comprehensive analysis of various types of cementing media used to cement various dental restorations such as crowns, bridges etc. are presented. Effects of various cementing media on the retention of dental post in the root canal have been estimated. The system is mainly consists of strain gauges mounted on a cantilever, a specially design amplifier, data acquisition system (ADC0809), Micro-...

Tetragonal Zirconia Polycrystals stabilized with 3% mol. content of yttria (3Y-TZP) has excellent properties in terms of strength and fracture toughness. These properties are mostly imputable to the transformation toughening mechanism, by which the doped metastable tetragonal phase of zirconia transforms to monoclinic under applied stress ahead of a crack. This phenomenon is accompanied by a vo...

Foreign bodies lodged in the bronchial tree are normally retrieved by bronchoscopy, but if this fails then thoracotomy is necessary. The case history is presented of a patient who had inhaled a dental post which could not be retrieved either by flexible or rigid bronchoscopy. Using biplane screening and intravascular retrieval devices introduced via an endotracheal tube, the dental post was rem...

After over two decades of discussions, promises and indecisions, the year 2016 marked the birth of the School of Specialisation in Paediatric Dentistry, which is now a reality. The importance of dental post-graduate specialisation schools has been debated since the Degree Course in Dentistry was established. Previously, in Italy only two dental branches - Oral Surgery and Orthodontics - had obt...

statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...
