OBJECTIVES This in vitro study determined the effect of enamel pretreatment with phosphoric acid and ethylenediaminetetraacetic acid (EDTA) on the bond strength of strong, intermediary strong, and mild self-etching adhesive systems. METHODS Ninety sound human premolars were used. Resin composite cylinders were bonded to flat ground enamel surfaces using three self-etching adhesive systems: st...

AIMS These were to firstly evaluate the shear bond strength of a composite resin to primary dental enamel treated with a standard adhesive system but with varying phosphoric acid etching times along with a self-etching prime, secondly to analyse the etching patterns using SEM. METHODS Forty primary molars were used. In the first three groups, following acid etching, a layer of Prime & Bond NT...

statement of problem: hemostatic agents may affect the micro-leakage of different adhesive systems. also, chlorhexidine has shown positive effects on micro-leakage. however, their interaction effect has not been reported yet. objectives: to evaluate the effect of contamination with a hemostatic agent on micro- leakage of total- and self-etching adhesive systems and the effect of chlorhexidine a...

The aim of this study was to evaluate the influence of a low-viscosity bonding resin applied over a self-etching adhesive system on the microtensile bond strength (microTBS) of indirect restorations. Comparisons were made using One Up Bond F (OB) self-etching adhesive system, Single Bond (SB) one-bottle adhesive system and Scotchbond Multi Purpose Plus (SMP) bonding component. Thirty bovine inc...

Background and Aim: Recurrent caries and low bond strength are the main causes of composite restorations failure. This study sought to assess the effect of chlorhexidine (CHX) on micro-shear bond strength (MSBS) to dentin of a fourth generation adhesive system and a universal bonding agent after aging. Materials and Methods: This in vitro study used 32 extracted third molars and 3-5mm thick de...

BACKGROUND This paper aimed to study the effect of two enamel protective agents on the shear bond strength (SBS) of orthodontic brackets bonded with conventional and self-etching primer (SEP) adhesive systems. METHODS The two protective agents used were resin infiltrate (ICON) and Clinpro; the two adhesive systems used were self-etching primer system (Transbond Plus Self Etching Primer + Tran...

objectives: this study aimed to evaluate the effects of saliva contamination on the metallic bracket microleakage bonded with two moisture-tolerant bonding systems. materials and methods:  ninety freshly extracted premolar teeth were randomly divided into six groups of 15 with the following treatments: g1 (control): after acid etching, assure primer and assure adhesive were applied to non-conta...

background: prompt l-pop is a self-etching dentin adhesive, which is recommended to use with both compomers and composite resins. the aims of this investigation were to determine and compare the microleakage, shear bond strength, and shear push out strength of composite and compomer to dentin with application of prompt l-pop as adhesive system. methods: after application of prompt l-pop on the ...

background: based on contradictory findings concerning the use of lasers for enamel etching, the purpose of this study was to investigate the shear bond strength of teeth prepared for bonding with er-yag laser etching and compare them with phosphoric acid etching. materials and methods: in this in vitro study forty – eight premolars, extracted for orthodontic purposes were randomly divided in t...
