BACKGROUND AND AIM: According to the effect of the adhesive and substrate type on the bond strength, examination of the adhesive is required in all aspects. The aim of this study was to evaluate the shear bond strength of different adhesive systems to normal dentin (ND) and caries affected dentin (CAD) in permanent teeth. METHODS: Thirty extracted molars with small occlusal caries were selected...

Our experiment evaluated the microleakage in resin composite restorations bonded to dental tissues with different adhesive systems. 40 class V cavities were prepared on the facial and lingual surfaces of each tooth with coronal margins in enamel and apical margins in cementum (root dentin). The teeth were restored with Z100 resin composite bonded with different adhesive systems: Scotchbond Mult...

background: the aim of this study was to compare the shear bond strength of four one-step self-etch adhesives with different ph values to enamel and dentin. materials and methods: in this in vitro study, 200 bovine permanent mandibular incisors were used. four one-step self-etch adhesives with different ph values were tested both on enamel and on dentin: adper™ easy bond self-etch adhesive (ph ...

The categorical framework of M-adhesive transformation systems does not cover graph transformation with relabelling. Rules that relabel nodes are natural for computing with graphs, however, and are commonly used in graph transformation languages. In this paper, we generalise M-adhesive transformation systems to M,N -adhesive transformation systems, where N is a class of morphisms containing the...

OBJECTIVE This in vitro study aimed to compare the microleakage of orthodontic brackets between enamel-adhesive and adhesive-bracket interfaces at the occlusal and gingival margins bonded with different adhesive systems. MATERIALS AND METHODS A total of 144 human maxillary premolar teeth extracted for orthodontic reasons was randomly divided into four groups. Each group was then further divid...

Length of resin tags yielded by utilization of an one-step conventional adhesive system and self-etching adhesive system on unground enamel was observed. In study Groups I and III, the enamel surface was etched for 60 seconds with 35% phosphoric acid gel and adhesive systems PQ1 (Ultradent Products, Inc) and Adper Prompt L Pop (3M/ESPE) were applied. Adper Prompt L Pop (3M/ESPE) was also applie...

background: the use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. this study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. methods: sixty freshly extracted human premolars were used for this study...
