The objective of this study was to investigate the effect of various luting cement systems on bond strength of fibre-reinforced posts to root canal dentine. 40 extracted single rooted sound premolar teeth were root filled, decoronated and randomly divided into four groups. Fibre posts, AesthetiPlusTM (Bisco,Inc. Schaumburg, IL, USA) were cemented using four luting cements: Group A (control): El...

PURPOSE Over the past years, the adhesion of fiber posts luted with simplified adhesive systems has been a matter of great interest. The aim of this study was to assess the post retentive potential of a self-adhesive resin cement using different adhesive systems to compare the push-out bond strengths of fiber posts. MATERIALS AND METHODS The post spaces of 56 mandibular premolar roots were pr...

UNLABELLED The dawn of minimally invasive dentistry has led to the development of materials which rely on the use of effective adhesion to bond to remaining tooth tissue. Successful adhesive bonding is dependent upon appreciating the quality of the dental substrate, appropriate clinical handling of the material and patient, together with an appreciation of the chemistry of the adhesive. This pa...

AIM This study investigated the effect of different fiber inserts (glass and polyethylene), bonding agents, and resin composites on the gingival margin microleakage of class V composite restorations. MATERIALS AND METHODS Sixty premolars were sterilized and mounted in acrylic resin bases. Class V cavities were prepared buccally and lingually, 1 mm below the cementoenamel junction, comprising ...

To evaluate the bond strength of different universal adhesives on deciduous tooth dentineand their relationship with composition and potential hydrogen (pH). Methods: An in vitromicro push-out test 150 samples (n = 50) per group adhesive, namely, Adhese Universal(ADH; Ivoclar Vivadent), Futurabond U (FUT; Voco GmbH) (Test), Scotchbond Universal withpre-conditioning (SCO; 3M) (Control), to recor...

BACKGROUND Newer dentin bonding agents were developed to improve the quality of composite restoration and to reduce time consumption in its application. The aim of the present study was to evaluate tensile bond strength of 6(th), 7(th) and 8(th) generation bonding agents by in vitro method. MATERIALS AND METHODS Selected 60 permanent teeth were assigned into 20 in each group (Group I: 6(th) g...

The objective of this study was to evaluate the tensile (σt) and shear bond strength (σs) of a glass-infiltrated alumina-based zirconia-reinforced ceramic (IZ Vita In-Ceram Zirconia) to a composite resin, testing the hypothesis that silica coating (SC Cojet, 3M-Espe) produces higher bond strength values than other ceramic surface treatments. Specimens were fabricated and tested according to the...

OBJECTIVES The aims of this study were to evaluate the effect of resin composite (Filtek Z250 and Filtek Flow Z350) and adhesive system [(Solobond Plus, Futurabond NR (VOCO) and Adper Single Bond (3M ESPE)] on the microtensile (μTBS) and microshear bond strength (μSBS) tests on enamel, and to correlate the bond strength means between them. MATERIAL AND METHODS Thirty-six extracted human molar...

This study evaluated the shear bond strength, failure modes, and confocal microscopy of two different amalgam alloy restorations lined with five adhesive systems. Two regular-set high-copper dental amalgam alloys, Amalcap Plus and Valiant Ph.D, and five commercially available adhesive systems were selected. One hundred and twenty freshly-extracted human third molars were used for the study. The...
