OBJECTIVE To evaluate the influence of Expasyl® gingival retraction paste on the shear bond strength of self-etch and total-etch adhesive systems. MATERIALS AND METHODS Twenty-four specimens of extracted, caries-free, sound human molars were used in this study. The molars were then cut vertically into halves through the buccal and lingual cusps. Forty-eight specimens were divided into four gr...

introduction: retention of fiber reinforced composite posts depends on the bond strength between post and cement, and cement and root dentin. the aim of this study is to evaluate the bond strength of one type of fiber post to radicular dentin with different adhesive cements. materials and methods: crowns of 44 caries-free, human premolar were removed 2 mm below the cej and the roots were endodo...

BACKGROUND This study was carried out to evaluate the nanoleakage of two types of nanofilled adhesive systems in Class V composite resin restorations. MATERIALS AND METHODS Totally 60 human premolars were randomly assigned to two groups (n = 30). Standardized round Class V cavities (enamel and dentin margins) were prepared. A total-etch (N-Bond total etch) (Ivoclar Vivadent) and self-etching ...

This study evaluated the effect of multiple consecutive adhesive resin coatings of adhesive bonded to human dentin on nanoleakage and resin-dentin bond strength. Resin bonded dentin specimens were prepared using a total-etch adhesive (One-Step Plus) applied as multiple consecutive coating, or using two self-etch adhesive systems (iBond or Fluoro Bond). For the total-etch adhesive, resin applica...

Background: Adhesive procedures have become an integral part of today’s restorative dental procedures. This study was carried out to evaluate the effect of contaminants such as saliva, blood, and hemostatic agents on the shear bond strength of a self-etch adhesive system Clearfil SE Bond, one-step, self-etch adhesive system AdperTM Easy One and a total-etch adhesive system AdperTM Single Bond 2...

in recent years, newly developed solvent-free dental adhesives have been introduced. the aim of this study was to evaluate the marginal integrity of a new one-step solvent-free self-etch adhesive and to compare it with a commonly used two-step self-etch adhesive as the gold standard.class v cavities (2×4×1.5 mm) were prepared on the buccal aspects of 28 human premolars. the cervical margins of ...

This in vitro study evaluated the bond strength of adhesive restorative materials to sound and eroded dentin. Thirty-six bovine incisors were embedded in acrylic resin and ground to obtain flat buccal dentin surfaces. Specimens were randomly allocated in 2 groups: sound dentin (immersion in artificial saliva) and eroded dentin (pH cycling model - 3× / cola drink for 7 days). Specimens were then...

OBJECTIVES The purpose of this study was to assess the shear bond strength (SBS) of metal brackets when placed with a caries protective adhesive patch. METHODS Forty stainless steel brackets (Ormco) were bonded to 40 bovine enamel samples according to the following conditioning/bonding procedures using a resin-based orthodontic luting material (Heliosit Orthodontic, N=10 per group): (A) 35% p...
