OBJECTIVES The aim of this study was to compare the technique sensitivity of a one-bottle total-etch adhesive and a self-etch primer adhesive to the moisture condition of the dentine substrate. METHODS The methods used were hydraulic conductance, light microscopy and scanning electron microscopy. RESULTS When the moisture conditions of the dentine surface are modified with respect to the st...
مقدمه:آگاهی یافتن از سیستمهای باندینگ سلفاچ با کمترین میزان ریزنشت میتواند راهنمایی در انتخاب نوع ادهزیو مناسب درهنگام آلودگی با بزاق و کاهش زمان کار دردرمان فیشورسیلانت به ویژه در کودکان باشد. هدف از این تحقیق تعیین تاثیر آلودگی با بزاق بر ریزنشت سیلانتها در سیستمهای ادهزیو با اسیدیته مختلف بود. مواد و روشها:در این بررسی از 54 دندان مولر سوم کشیده استفاده شد. شیارهای سطح جونده با فرز رون...
OBJECTIVES OBJECTIVE To evaluate the effect of thermo-mechanical cycling (TMC) on the microleakage (μL) and axial gap width (AG) of Class V bonded restorations in premolars using self-etching adhesive systems. The bond strength of composite restorations to dentin (μTBS) using the same adhesives was also evaluated in third molars after water storage: 24 h and 6 months. The research hypotheses...
background and aims. the aim of this study was to evaluate the effect of dilution and curing methods of an etch-and-rinse adhesive and a self-etching primer from the same manufacturer at early exposure time on cytotoxicity of primary hu-man gingival fibroblasts. materials and methods. primary human gingival fibroblasts were exposed to different dilutions of adper single bond (asb) and adper pro...
OBJECTIVE STATEMENT OF PROBLEM Adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique. PURPOSE OF STUDY This study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (GIC) using self-etch adhesives with different pH values. MATERIALS AND METHODS One hundred specimens (6×4×2 mm) were m...
STATEMENT OF THE PROBLEM In the sandwich technique, the undesirable bond between the composite resin and glass-ionomer cement (GIc) is one of the most important factors which lead to the failure of restoration. Total-etch and self-etch adhesives may improve the bond strength based on their pH. PURPOSE The purpose of this study was to evaluate the shear bond strength between the nanofilled com...
Background and aims. The aim of this study was to evaluate the effect of dilution and curing methods of an etch-and-rinse adhesive and a self-etching primer from the same manufacturer at early exposure time on cytotoxicity of primary human gingival fibroblasts. Materials and methods. Primary human gingival fibroblasts were exposed to different dilutions of Adper Single Bond (ASB) and Adper Prom...
OBJECTIVES The purpose of this study was to evaluate the performance of both single and double applications of (Adper Prompt L-Pop) self-etching dental adhesive, when used with three classes of light-activated restorative materials, in comparison to the performance of each restorative system adhesive. Evaluation parameters to be considered for the adhesive systems were (a) immediate marginal ad...
This study determined the effect of cleansing solutions on microtensile bond strengths of self-etch adhesives to saliva-contaminated dentin. Seventy five human molars were ground flat to expose mid-depth dentin, and randomly assigned to 5 groups (n=15): no contamination, saliva contamination without cleansing, saliva and cleansing with water, saliva and cleansing with 2% chlorhexidine, and sali...
OBJECTIVES The aim of this study was to evaluate the bond strength of one-step adhesive systems to dry or moist dental substrate. METHODS Thirty human third molars were sectioned into two halves, in the mesio-distal direction, parallel to the long axis of the tooth. Each half was embedded in a polystyrene resin cylinder so that the buccal/lingual surface remained exposed. This exposed surface...
