statement of problem: microleakage is one of the most important problems in composite restorations. one way to reduce the microleakage is decreasing the total amount of resin by insertion of fibers in composite restorations. objectives: this study aimed to compare the microleakage of silorane and methacrylate-based composites (a nanohybrid) in class ii restorations with gingival margins on the ...

No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthet...

The objective of this study was to analyze the distribution of tensile stresses in indirect restorations prepared in several composite cavity bases. Elastic moduli of 20 materials were measured by nanoindentation technique for finite element analysis. Axisymmetric models of posterior onlays were constructed using combinations of two onlay materials and three cavity base materials. Thickness of ...

This study investigated factors associated with the longevity of resin composite restorations, which were placed in 97 patients (mean age of 58 years) by 24 dentists in Nagasaki University Hospital between 1995 and 2005. All patients were under the charge of the principal investigator (SK) and most of them had been regularly checked up for up to 11 years. A total of 503 resin composite restorat...

OBJECTIVES Extensively destroyed teeth are commonly restored with composite resin before cavity preparation for indirect restorations. The longevity of the restoration can be related to the proper bonding of the resin cement to the composite. This study aimed to evaluate the microshear bond strength of two self-adhesive resin cements to composite resin. MATERIALS AND METHODS COMPOSITE DISCS W...

AIM To evaluate the microtensile bond strength (microTBS) of four adhesive systems to dentin, using self- and light-cured resin composites. METHODS AND MATERIALS Crowns of human molars were separated from the roots, and the occlusal surfaces were ground to obtain flat superficial dentin. Three etch-and-rinse adhesives--All-Bond 2, One-Step Plus, and OptiBond Solo Plus--and one self-etching pr...

UNLABELLED Prosthetic-restorative approach for the restoration of tooth wear. Case report OBJECTIVE This article presents a case report of combined prosthetic-adhesive rehabilitation in a patient with a generalized tooth wear. METHODS A combined treatment adhesive - prosthetic was proposed to a male patient of 65 years old having a clinically significant tooth wear, with dentine exposure an...
