STATEMENT OF THE PROBLEM Sufficient adhesion between silorane/methacrylate-based composites and methacrylate impregnated glass fiber increases the benefits of fibers and enhances the mechanical and clinical performance of both composites. PURPOSE The aim of this study was to evaluate the compatibility of silorane and methacrylate-based composites with pre-impregnated glass fiber by using flex...

Background and Aim: Improving the bond strength at the resin-dentin interface is an important challenge in adhesive dentistry. This study examined the effect of low-power, non-thermal atmospheric pressure plasma (NT-APP) treatments on the adhesion of a self-adhesive resin composite to dentin. Materials and Methods: In this experimental in-vitro study, buccal enamel of extracted bovine incisors...

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with uni-directional glass fibers. Epoxy adhesive impregnated fiber were used to join composite plates joints. It is aimed strengthen the joint by layers between two plates. The loads of obtained compared attached non-reinforced adhesive. Also, 0o, 15o 30o and 45o re...

PURPOSE This study evaluated the shear bond strengths of light-polymerized urethane dimethacrylate (Eclipse) and heat-polymerized polymethylmethacrylate (Meliodent) denture base polymers to intraoral and laboratory-processed reline materials. MATERIALS AND METHODS Thirty disks measuring 15 mm diameter and 2 mm thick were prepared for each denture base material following the manufacturers' rec...

Bond failure of a no-mix adhesive was evaluated in 320 patients followed longitudinally during orthodontic treatment. Factors evaluated were the patient's gender, the complexity of the appliance, the bond site location, initial crowding, and caries development. The overall bond failure rate was 7.2%. Bond failures were significantly higher in the mandible, with the second premolars showing the ...

Two main mechanical tests are commonly used to measure the critical shear stress of an adhesive, Single Lap Shear (SLS) test and Thick Adherend Test (TAST). In these tests, assessment is performed with mode mixity. this work, a two-dimensional Finite Element Model asymmetric TAST set-up few on titanium/epoxy specimens. The model takes into account shift adhesive joint loading axis. impact shift...

On-demand adhere to and detach from soft wet surfaces are crucial for hydrogels applications in tissue engineering, machines, robotics. Whereas strong adhesion has been achieved between hydrogels, on-demand switching weak benign detachment is still under explorations. Herein, we report an approach switchable by invoking a mechanical process, wrinkling. The demonstrated bonding two hydrogel adhe...

This study evaluated the effect of 24 h (1d) and one-year (1yr) water storage on the microtensile dentin bond strength of a two-step total-etch and a two-step self-etch adhesive system. Ten extracted human third molars were sectioned perpendicularly to their long axis to expose flat occlusal dentin surfaces. Teeth were divided into two groups (n=5) according to the adhesive used: a two-step etc...

OBJECTIVES Effect of a dentin adhesive system containing antibacterial monomer-MDPB (Clearfil Protect Bond) on the shear bond strength of all-ceramic-IPS Empress 2 restorations luted with three different dual-polymerizing systems (Variolink 2, RelyX ARC and Panavia F 2.0) to dentin was investigated. METHODS One hundred and eight all-ceramic discs (2 x 3mm; IPS Empress 2) were fabricated and u...

OBJECTIVES This study examined the effect of one-bottle adhesives with different acidities on bonding to chemical-cured and light-cured resin composites. METHODS Twenty-four non-carious human third molars were divided into eight groups. A flat dentin surface was created for each tooth. Acid-conditioned dentin surfaces were bonded with Prime&Bond NT (Dentsply), OptiBond SOLO (Kerr), Single Bon...
