This study evaluated the effect of dentin surface treatment on shear bond strengths of two light- cured glass ionomer restorative materials to dentin. Cylinders of Fuji II LC and VariGlass VLC were bonded to dentin surfaces that were untreated, treated with a 10% polyacrylic acid (GC Conditioner), or treated with a dentin bonding agent primer (Prisma Universal Bond 3 Primer). Specimens were the...

PURPOSE To investigate the influence of cement film thickness, cement type, and substrate (enamel or dentin) on ceramic fracture resistance. MATERIALS AND METHODS One hundred extracted human third molars were polished to obtain 50 enamel and 50 dentin specimens. The specimens were cemented to 1-mm-thick lithium disilicate ceramic plates with different cement film thicknesses (100 and 300 μm) ...

OBJECTIVES This study determined the effect of the air-stream application time and the bonding technique on the dentin bond strength of adhesives with different solvents. Furthermore, the content and volatilization rate of the solvents contained in the adhesives were also evaluated. MATERIALS AND METHODS Three adhesive systems with different solvents (Stae, SDI, acetone; XP Bond, Dentsply De ...

Aim: To evaluate and compare the effect of saliva decontamination procedure on shear bond strength a Universal eighth generation adhesive system to dentin after polymerization. Materials & Method: Forty extracted non-carious premolars were mounted acrylic block their occlusal surfaces grounded flat exposed middle depth dentin. The teeth then randomly divided into five Groups: Group A(contro...

To investigate the bonding of tooth-colored indirect restorations to cervical dentin, shear bond strengths of bonded resin inlays to cervical dentin and mid-coronal dentin were investigated and compared. Indirectly fabricated composite inlays (Estenia) were cemented with a dual-cured resin cement (Panavia Fluoro Cement II) to either cervical or mid-coronal dentin. Resin cement was cured with or...

background : composite resin restorations may have a short lifespan due to the degradation of resin–dentin interface. ethanol wet bonding technique may extend the longevity of resin–dentin bond. the purpose of this one year randomized clinical trial was to compare clinical performance of two adhesives with ethanol wet bonding technique. materials and methods: this randomized clinical trial was ...

background: antioxidizing agents have recently been suggested to compensate decreased bond strength of resin materials to bleached tooth tissues. this study compared the shear bond strength (sbs) of three different adhesives on bleached dentin immediately after bleaching, bleached/delayed for 1 week, and bleached/applied antioxidizing agent. materials and methods: the dentinal surfaces of 132 i...
