AIM This study evaluated the bond strength and failure mode of enamel/resin-based composite veneers bonded with three different dual cured resin adhesive systems. METHODS AND MATERIALS Standard preparations for laminate veneer restorations were made on 30 human central incisors using depth cutting burs (0.5 mm depth at the incisal area and 0.3 mm at the gingival area). Thirty indirect laminat...

The present study evaluated the durability of bond strength between zirconia and 3 different resin cements. Thirty stabilized tetragonal zirconium-dioxide blocks were duplicated in dual-curing resin core build-up material specimens. Resin blocks were randomly luted to zirconium surfaces using 1) Clearfil Esthetic Cement (CLF), 2) RelyX Unicem Aplicap (RELX), or 3) Multilink Automix (MLA). After...

This study investigated the effects of the cement type and the water storage time on the push-out bond strength of a glass fiber post. Glass fiber posts (Fibrekor, Jeneric Pentron) were luted to post spaces using a self-cured resin cement (C&B Cement [CB]), a glass ionomer cement (Ketac Cem [KC]) or a resin-modified glass ionomer cement (GC FujiCEM [FC]) according to the manufacturers' instruct...

This study verified the optical density of four composite resin luting agents - RelyX ARC (RY), Enforce (E), C&B Cement (CB) and Flow it (FI), at thicknesses of 2, 3, and 4 mm. The optical density of the luting agents was compared with that of enamel and dentin at the same thicknesses. Fifteen tooth crowns were embedded in PVC cylinders with self-cured acrylic resin. In addition, acrylic resin ...

STATEMENT OF PROBLEM No clear consensus exists regarding the choice of luting agents for the retention of cast metal dowels used as a treatment alternative for endodontically treated teeth with excessive loss of coronal tooth structure. PURPOSE The purpose of this in vitro study was to investigate the retention of the dowel/luting agent/tooth complex while applying different luting agents to ...

objective: the purpose of this study was to evaluate the solubility of three luting cements in artificial saliva. materials and methods: twenty disks (10×4 mm) of polycarboxylate, zinc phosphate and glass ionomer cements were prepared according to manufactures’ instructions. after setting, they were desiccated and each ten specimens were immersed in artificial saliva with special ph (3 or 5), c...

Purpose To evaluate the degree of conversion (DoC) self-adhesive resin luting cements when irradiated through different fiber post lengths. Methods A total 60 teeth were sectioned to achieve lengths 4 mm, 7 and 10 while posts trimmed give 3 6 9 mm Post space was created accommodate 1 cement apically. Two (Multilink Speed RelyX U200) used. four cycles 20 s irradiation done with an attenuated ref...
