Effect of luting materials and root third on glass fiber posts bonding strength after hydrothermal aging.

ABSTRACT:

Statement of the problem

Teeth with extensive coronal destruction face the challenge of retaining the restorative materials; however, glass fiber posts cemented with resin materials can help to address the issue. The retention of these posts depends on the bond strength to the dentin structure and may vary significantly along the root thirds.

Purpose

This study aimed to evaluate the effect of different luting materials and root thirds on the bonding strength of glass fiber posts to radicular dentin after hydrothermal aging.

Materials and methods

Seventy bovine incisors were divided into 7 groups (n = 10), according to the luting materials: Panavia V5 (PV5), Rebilda DC (RDC), LuxaCore Z (LCZ), Allcem Core (ACC), RelyX Ultimate (RXU), RelyX U200 (RXU200) or Fuji Plus (F
