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...

The objective this study was to evaluate in vitro the bond strength of two etch-and-rise and one self-etching adhesive system after dentin irradiation with Er:YAG (erbium: yttrium aluminum garnet) laser using microtensile test. The results revealed that the groups treated with laser Er:YAG presented less tensile bond strength, independently to the adhesive system used. The prompt L-pop adhesive...

background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...

OBJECTIVES To evaluate the effects of dentin pretreatment and temperature on the bond strength of a universal adhesive system to dentin. MATERIAL AND METHODS Ninety-six extracted non-carious human third molars were randomly divided into 12 groups (n=8) according to Scotchbond Universal Adhesive (SbU) applied in self-etch (SE) and etch-and-rinse (ER) mode, adhesive temperature (20°C or 37°C) a...

objective: this study evaluated the influence of storage time on micro-shear bond strength of two self-etching materials to enamel and dentin. materials and methods: human third molar teeth were sectioned to 1.5 mm thick beams and randomly divided into 2 groups. in group i, se bond and in group ii, tri-s bond was used to bond a composite rod (ap-x) to each treated surface. specimens were prepar...

Composites are being used extensively in several engineering applications. However, the efficiency of the joints used in joining composites and metals can be improved. To move towards a sustainable and environment friendly future, natural fibre composite material was used. Towards the above objective, research work was carried out for the assembly between a composite and aluminium. Three differ...

The purpose of the present work was to prepare buccal adhesive tablets of miconazole nitrate. The simplex centroid experimental design was used to arrive at optimum ratio of carbopol 934P, hydroxypropylmethylcellulose K4M and polyvinylpyrollidone, which will provide desired drug release and mucoadhesion. Swelling index, mucoadhesive strength and in vitro drug release of the prepared tablet was ...

The durability of adhesive joints is of special concern in structural applications and moisture has been identified as one of the major factors affecting joint durability. This is especially important in applications where joints are exposed to varying environmental conditions throughout their life. This paper presents a methodology to predict the stresses in adhesive joints under cyclic moistu...

We have investigated the effectiveness and safety of a newly developed biological adhesive for repair of meniscal tear. The adhesive was composed of disuccinimidyl tartrate (DST) as a crosslinker and human serum albumin (HSA) as a hardener. To determine adequate concentration, bonding strength was measured using a tensiometer 5 min after applying the adhesive on the avascular zone tear of porci...
