AIM To compare the effect of different chemical solvents on glass fiber reinforced posts and to study the effect of these solvents on the shear bond strength of glass fiber reinforced post to core material. MATERIALS AND METHODS This study was conducted to evaluate the effect of three chemical solvents, i.e. silane coupling agent, 6% H2O2 and 37% phosphoric acid on the shear bond strength of ...

OBJECTIVES The present study was designed to test the null hypothesis that there is no difference in the fracture resistance of pulpless teeth restored with different types of post-core systems and full coverage crowns. METHODS Extracted human upper premolars were restored with a fiber post, prefabricated metallic post or cast metallic post-core. Teeth with full crown preparations without pos...

PURPOSE The objective of this study was to determine the effect of the color of a background substructure on the overall color of a zirconia-based all-ceramic crown. MATERIALS AND METHODS Twenty one posterior zirconia crowns were made for twenty subjects. Seven premolar crowns and six molar crowns were cemented onto abutments with metal post and core in the first and second group. In the thir...

This study presents an innovative technique of executing soil nails called sectorized post grouting (SPG). The most utilized nail is gravity grouting, with the literature reporting advances in pressurized grouting. Although obtaining higher pullout resistance nails, mostly done single-stage does not compensate for exudation and its use lengths difficult. Thus, a has been developed that compensa...
