STATEMENT OF THE PROBLEM Self-etch adhesives can activate matrix metalloproteinase (MMP) which hydrolyzes organic matrix of demineralized dentin. Epigallocatechin gallate (EGCG), especially found in green tea, could inhibit the activation of MMP. PURPOSE The aim of this study was to evaluate the effect of adding Epigallocatechin gallate (EGCG) into two types of adhesives on dentin bond streng...

OBJECTIVES The purpose of this in vitro study was the evaluation of the bond strength and its durability of two composite resins to zirconia ceramic after using different surface conditioning methods. METHODS Plexiglas tubes filled with composite resin were bonded to zirconia ceramic discs (Cercon) which were either in their original state as supplied by the manufacturer only cleaned in isopr...

Lightweight concrete (LWC) is used in the construction of partition and panel walls framed structures because it reduces dead load acting on structure. Rubberized lightweight aggregate made by using waste rubber tyre chips as a partial replacement coarse which increases ductility, toughness minimizes impact effect concrete. The presence content decreases compressive strength bond strength, affe...

Purpose: The purpose of the present study was to investigate the bond strength of an indirect composite material to a magnetic stainless steel alloy. Materials and Methods: The surfaces of machined magnetic stainless steel alloy specimens were abraded with 600-grit silicon carbide paper and then grouped according to the type of surface treatment given: 1) without preparation, 2) tribochemical s...

BACKGROUND Longevity of post-retained restoration is highly depended on bonding stability of fiber post (FP) to root dentin. This study evaluated the effect of different antibacterial/adhesive approaches on bonding durability of FPs luted into root canal with a self-etch cement. MATERIAL AND METHODS Seventy-two human maxillary central incisor roots were divided into six groups after endodonti...
