BACKGROUND The purpose of this study was to compare the shear bond strength and adhesive remnant index (ARI) at the enamel-bonding interface of precoated and conventionally bonded brackets, utilizing standardized procedures. METHODS The test sample consisted of 90 recently extracted bovine permanent mandibular incisors. The teeth were bonded using the same protocol and were tested in three di...

Background and Aim: By application of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) as a remineralizing agent, it may be feasible to only remove the carious dentin and better preserve the tooth structure. This study aimed to assess the shear bond strength of composite to primary enamel treated with CPP-ACP using total-etch and self-etch bonding systems. Materials and Methods: T...

Background and objectives: The aim of the study was to evaluate the shear bond strength of brackets bonded with three bonding systems under laboratory conditions and to compare resin tag penetration after debonding. Materials and methods: The study was done on 60 extracted human premolar teeth, divided into three groups of 20 teeth each. Each group was bonded with three different types of bondi...

The demand for more complex and multifunctional micro systems with enhanced performance characteristics for military applications is driving the electronics industry toward the use of best-of-breed materials and device technologies. Threedimensional (3-D) integration provides a way to build complex microsystems through bonding and interconnection of individually optimized device layers without ...

This study aimed to evaluate the effect of adhesive systems based on a thiouracil monomer on bonding to silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M.C.12). Disk specimens were cast from the alloy and then air-abraded with alumina. The disks were bonded using six bonding systems selected from four primers and three luting materials. Shear bond strengths were determined both befor...

Two thermal challenges for current and next generation microelectromechanical systems (MEMS) applications are discussed. The first topic is the fundamental investigations of phase change phenomena in the microscale. It has been demonstrated that microresistive heaters can generate single, spherical and controllable thermal bubbles with diameters between 2 and 500 mm. Both simplified steady stat...

Background: The old concept of total-etch/dry bonding has been superseded by total-etch/wet bonding, and later on by the self-etch systems. Manufacturers have introduced single bottle systems to be used in total-etch, self-etch, or selective-etch modes under both dry and moist conditions. The aim of this study was to evaluate shear bond strengths of three different dental adhesives under dry an...
