The establishment of a reliable bonding has been known as one of the major challenges in adhesive dentistry although important improvements in adhesive systems have been made in the last 30 years. The goals of using these bonding agents are to provide micromechanical retention of the restoration, enhance the bonding strength between the resin and the tooth structure, reduce the microleakage acr...

Light-cured adhesive systems have been widely used in dental clinical practice. Bonding to dentin remains poorly understood and unreliable. Previous studies have shown that quality of hybrid layer (HL: interface between adhesive layer and dentin) is very important to the reliability of whole bonding. Raman spectroscopic studies of the adhesive distribution in HL indicate that monomers do not co...

Adhesive bonding is a well-known technics to assembly dies or wafer on a host substrate through polymer or solder bumps. To combine electronic and photonic systems on a single chip, we propose hereby to use AuSn alloy as bonding medium combined to waferscale technology and post-bonding III-V processing alleviating so the need of alignment accuracy between wafers. For instance, high density LED’...

OBJECTIVES To investigate the effects of adhesion technique using different contemporary adhesive systems on the cuspal movement in class II composite restorations in human premolar teeth. METHODS Human premolar teeth were prepared with class II cavities and then restored with composite and etch-and-rinse (Adper Scotchbond Multi Purpose and Adper Single Bond) or self-etch (Clearfil SE Bond an...

Small Nim(C60)n clusters with n1m<4 are studied using the tight-binding molecular-dynamics method generalized to treat heteronuclear systems. Our results confirm recent experimental deduction of the bonding behavior of Ni towards C60 . The direction of the charge transfer is found to depend on the geometry of the Nim(C60)n cluster. Furthermore, the present results reveal a striking dissimilarit...

This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were d...

OBJECTIVE To evaluate the effect of silica dioxide (SiO2) nanofillers in different bonding systems on shear bond strength (SBS) and mode of failure of orthodontic brackets at two experimental times. METHODS Ninety-six intact premolars were divided into four groups: A) Conventional acid-etch and primer Transbond XT; B) Transbond Plus self-etch primer; and two self-etch bonding systems reinforc...

PURPOSE The aim of this study was to evaluate microbial contamination and inhibitory effect against Streptococcus mutans (SM) of Prime & Bond (PB), Single Bond (SB) and Excite (EX) bonding systems before use, and after 10 and 20 applications. METHODS The bonding material was collected by applying a drop of the material directly on broth brain-heart infusion. The samples were homogenized, dilu...

statement of problem: ceramics as in ceramo-metallic and all ceramic tooth restorations have grown popular owing to their high tissue compatibility and esthetic advantages. such restorations have the capability to deliver valuable services over a long period of time; however, failures under intraoral conditions are not unanticipated. purpose: the purpose of this in-vitro study was to investigat...
