PURPOSE The aim of this systematic review was to determine which dowel (post) and core system is the most successful when used in vivo to restore endodontically treated teeth. MATERIALS AND METHODS A MEDLINE, a Cochrane, and an EMBASE search (three specified searches) were conducted to identify randomized (RCT) and nonrandomized controlled clinical trials (CCT), cohort (CS), and case control ...

58 INTERNATIONAL DENTISTRY SA VOL. 8, NO. 4 Introduction The clinical success of fiber post-retained restorations depends on the establishment of a reliable bond at the root-post-core interfaces. In spite of the improvements in dental material technology, post to composite adhesion is still considered relatively low. Advances in silane coupling agents enhance bond strength by promoting adhesion...

BACKGROUND Fiber posts are widely used for restoration of mutilated teeth that lack adequate coronal tooth structure to retain a core for definitive restoration, bond between the fiber post and composite material depends upon the chemical reaction between the post surface and the resin material used for building up the core. In attempt to maximize the resin bonding with fiber post, different po...

BACKGROUND The incorporation of nano silver particles (AgNPs) to improve antibacterial properties of dental materials has become increasingly common. The aim of the present study was to compare the antibacterial activity and cytotoxicity effects of different fiber posts: glass fiber post, quartz fiber post, nano fiber post and silver fiber post. MATERIAL AND METHODS The antibacterial activity...

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...

A novel scintillating optical fiber is presented using a composite micro-structured quartz optical fiber. Scintillating materials are introduced into the multiple inclusions of the fiber. This creates a composite optical fiber having quartz as a cladding with an organic scintillating material core. X-ray detection using these fibers is compared to a collimated cadmium telluride (CdTe) detector ...

AIM The aim of this study was to investigate the fracture resistance and failure mode of premolars restored with composite resin using various prefabricated posts. METHODS AND MATERIALS Sixty sound maxillary premolars were divided into four equal sized groups. All but the control group received endodontic treatment followed by placement of mesiodistocclusal (MOD) composite restorations (Tetri...
