Comparative Evaluation of the Strength of Denture Base Resin repaired with Glass Fiber-reinforced Acrylic Resin: An in vitro Study.

Aim: The present study aimed at evaluating and comparing the transverse strength of heat polymerizing acrylic resin samples repaired using glass fiber-reinforced autopolymerizing acrylic resin with varying gap widths at the fracture site.

Materials And Methods: Heat polymerizing acrylic resin samples of dimensions 65 * 10 * 2.5 mm each were fabricated.

Comparative evaluation of the efficiency of four ceramic finishing systems.

Aim: To compare the effect of four different finishing systems and diamond paste on ceramic roughness with the objectives of evaluating the roughness of ceramic surface of prepared specimens after abrasion, finishing and polishing.

Materials & Methods: A total of 50 test specimens were fabricated in the form of discs of diameter 13mm and 0.6mm thickness.
