STATEMENT OF PROBLEM Patterns for custom cast posts and cores can be fabricated either by the direct or the indirect technique. Which technique is more accurate is unknown. PURPOSE The purpose of this in vitro study was to investigate the effect of pattern fabrication technique on the accuracy of post fit. MATERIAL AND METHODS Ten intact extracted premolar teeth with a single canal and simi...

conclusions the best balance between detection rate of prostate cancer and infectious complications of biopsies achieved in twelve-core biopsy protocol. twelve-core biopsy enhances the rate of prostate cancer detection with minimum adverse effects. patients and materials transrectal ultrasonography (trus) guided biopsy was performed in 180 patients suspicious for prostate cancer due to either a...

This is the first study on the free vibrational behavior of sandwich panels with flexible core in the presence of smart sheets of oil which is capable of the excitation of magnetic field. In order to model the core, the improved high order theory of sandwich sheets was used by a polynomial with unknown coefficients first degree shear theory was used for the sheets. The derived equations based o...

the arithmetic mean roughness, ra, values were determined by scanning electron microscopic technique of different core models (furazolidone, nitrofurantoin and acetyl salicylic acid), coated by hpmc film forming solution containing 10 wt% of various molecular weight pegs. the results showed that both plasticizer molecular weight and core surface free energy could have a significant influence on...

conclusions roll stitch technique had superior outcome compared to the modified kessler technique, when performed in the mcpj area. level of evidence: therapeutic (level iii) background proper suturing technique is needed to ensure good outcome in extensor tendon surgery. different techniques have been reported for the repair of extensor tendon injuries at the level of the metacarpophalangeal j...

The aim was to explore the survival of extensively damaged anterior teeth without ferrule restored with different fiber-reinforced composite (FRC) post-core foundations and crowns. Sixty extracted upper central incisors were decoronated randomly divided into four groups (n = 15). After endodontic treatment, specimens individualized as follows: control group (CTRL): multiple unidirectional FRC-p...

coronal tooth tissue can use a post to retain a core enabling definitive restoration. Post material has been, until recently, primarily metal--be it cast or prefabricated. Currently, fiber-posts are promoted as being advantageous due to a favorable failure mechanism which may protect the root from fracture [1]. Endodontic posts are necessary to provide adequate retention and support when no suf...
