Strength and Durability of a New Adhesive Bond to Superficial Dentin Using Etch and Rinse and Self-Etch Systems: An In Vitro Study

Sodium fluoride addition to a two-step etch-and-rinse adhesive system: effect on dentin microtensile bond strength and durability

Introduction: Studies have suggested that sodium fluoride (NaF) has an inhibitory effect on the activity of endogenous matrix metalloproteinase enzymes. This study assessed the effect of a fluoride-containing adhesive on microtensile bond strength (µTBS) over time. Material & Methods: In this experimental study, 36 extracted  third molars were used to evaluate the µTBS of...

Effect of Chlorhexidine Application on Dentin Bond Strength Durability of Two Etch-and-Rinse Adhesive versus a Universal Bond System

Effect of Tannic Acid Application on Durability of Bond of Etch and Rinse Adhesive Resins

Aim: To determine the effect of different concentrations and application times of tannic acid on bond strength to dentin. Materials and Methods: Occlusal surfaces of 180 human molars were randomly divided into two groups of immediate shear bond strength evaluation and evaluation after 2 months of storage in collagenase solution. Each group was divided into 10 subgroups according to the solution...

Effect of salivary contamination on the bond strength of total-etch and self-etch adhesive systems: an in vitro study.

AIM To evaluate the influence of salivary contamination during dentin bonding procedures on shear bond strength and to investigate the effect of contaminant-removing treatments on the recovery of bond strength for two dentin-bonding agents. MATERIALS AND METHODS Seventy-seven human maxillary and mandibular molars were randomly divided into two groups for total-etch adhesive (Single bond-3M ES...

Microtensile bond strength of etch-and-rinse and self-etch adhesive systems to demineralized dentin after the use of a papain-based chemomechanical method.

PURPOSE To evaluate the in vitro microtensile bond strength (microTBS) of etch-and-rinse and self-etch adhesive systems to demineralized dentin after the use of a papain-based chemomechanical method. METHODS 36 demineralized human dentin slabs were randomly distributed into two groups according to the method of caries removal: (1). Mechanical removal with manual excavators; (2) Chemomechanica...

Effect of Dimethyl Sulfoxide on Bond Strength of a Self-Etch Primer and an Etch and Rinse Adhesive to Surface and Deep Dentin

STATEMENT OF THE PROBLEM Composite bond to dentin is crucial in many clinical conditions particularly in deep cavities without enamel margins due to insufficient penetration of adhesive into demineralized dentin. PURPOSE The aim of this study was to assess the shear bond strength (SBS) of a methacrylate-based and a silorane-based composite resin to surface and deep dentin after pretreatment w...
