PURPOSE This study compared fluoridated bonding resin adhesion to primary enamel (Group 1), primary dentin (Group 2), permanent enamel (Group 3), and permanent dentin (Group 4). METHODS The buccal surfaces of 24 primary molars and 24 premolars were used. The bonding system and resin composite used in this study were Imperva Fluorobond and Lite-Fil IIA (Shofu Inc., Kyoto, Japan). Effects of to...

Aim: To evaluate and compare the effect of saliva decontamination procedure on shear bond strength a Universal eighth generation adhesive system to dentin after polymerization. Materials & Method: Forty extracted non-carious premolars were mounted acrylic block their occlusal surfaces grounded flat exposed middle depth dentin. The teeth then randomly divided into five Groups: Group A(contro...

objective: the aim of this study was to evaluate the microtensile bond strength to sound and caries-affected dentin using single bond and adper prompt-l-pop adhesives. materials and methods: sixteen extracted human molars with carious lesions extended halfway through dentin were ground to expose the caries affected and the surrounding normal dentin. the samples were divided into two groups of e...

UNLABELLED One-step self-etch adhesives are undoubtedly the most user-friendly adhesives, but have been associated with lower bonding effectiveness as compared to two-step and three-step adhesives. Conversion of a one-step self-etch system into a two-step self-etch adhesive by adding a bonding step, or into a three-step etch&rinse adhesive by adding a beforehand etching step and a bonding step ...

BACKGROUND Studies have shown a reduction in bond strength of composites and glass ionomer to bleached enamel and dentin. Several methods have been proposed to reverse compromised bond strength. OBJECTIVE The aim of this study was to evaluate the effect of delayed bonding and application of antioxidant agent on the bond strength of reinforced self-cured (Fuji IX) and light-cured glass ionomer...

Introduction: Simultaneous etching of enamel and dentin using the novel generation of adhesive systems with contracted operational steps, has shown a good clinical efficacy. The aim of this study was to evaluate the microleakage of composite restorations using the V and VII generations of adhesive systems on primary teeth. Methods: This study was performed on 45 human intact extracted primar...

The objective of this work was to determine bonding characteristics of a hydrophilic monomer formulation containing polymerizable cyclodextrin derivatives. The hypothesis was that a formulation containing hydrophilic cross-linking diluent comonomers and cyclodextrins with functional groups attached by hydrolytically stable ether linkages could form strong adhesive bonds to dentin. The previousl...

Recently, one-bottle resins adhesives have been developed to reduce the number of clinical steps of resin application. They are now widely used in clinical dental practice. However, little is known regarding the detailed mechanism of bond degradation. Therefore, this study evaluated the durability of one-bottle resin adhesives using long-term water storage testing. Resin-dentin bonded specimens...

AIM The aim of this study was to evaluate how cavity preparation and primer application methods influence the adhesion of composite resin to dentin using a self-etching system. METHODS AND MATERIALS Forty-eight extracted, sound human molars were divided into six groups (n=8) according to the method used for the surface preparation of the teeth (#600-grit paper disc, diamond bur, and Er:YAG la...

Background: The old concept of total-etch/dry bonding has been superseded by total-etch/wet bonding, and later on by the self-etch systems. Manufacturers have introduced single bottle systems to be used in total-etch, self-etch, or selective-etch modes under both dry and moist conditions. The aim of this study was to evaluate shear bond strengths of three different dental adhesives under dry an...
