Effect of Composite Resin and Restorative Technique on Polymerization Shrinkage Stress, Cuspal Strain and Fracture Load of Weakened Premolars.

Purpose: To compare shrinkage stress, cuspal strain and fracture load of weakened premolars restored with different conventional and bulk-fill composite resins and restorative techniques.

Materials And Methods: Fifty premolars received a 4.0 x 3.

The Use of Bulk-Fill Flow in the Customization of Glass Fiber Post.

Objectives:  The aim of this study is to evaluate the influence of different composite resin in the customization of glass fiber posts (GFPs) on bond strength and failure mode.

Materials And Methods:  Thirty bovine roots were selected. The wall roots were reduced so that each wall had a minimum dentin thickness of 1 mm.
