mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. carbomers are among the best mucosa-adhesive materials known. the aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing carbomers, either alone or in combination, to the data obtained from assessing the d...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

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: The clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (RMGIC) bonding to both dentin and resin composite. Therefore, the shear bond strength (SBS) of resin composite bonded to RMGIC utilizing different resin adhesives versus a GIC-based adhesive was compared. Materials and methods: In this in vitro study, 84 holes (5×2 mm) were pre...

For microoptics and microsystem assembly, solder bumping is introduced as a flexible and high precise joining alternative to adhesive bonding, especially if adhesives limit the system performance in terms of long term, high temperature, vacuum or UV stability. The bumping technology, which is based on jetting the liquid solder onto wetting surfaces, can be parameter optimised to work in complex...

In this paper, considering an adhesively bonded composite single-lap joint, a novel approach is presented to predict the peel and shear stress distributions of the adhesive layer for an ASTM standard test sample. In current method, the equilibrium equations are derived using the energy method and based on the Timoshenko’s beam theory. Two solution procedures then are discussed, one of which rep...

particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...
