The aim of the study was to verify the influence of surface sealants on the surface roughness of resin composite restorations before and after mechanical toothbrushing, and evaluate the superficial topography using atomic force microscope. Five surface sealers were used: Single Bond, Opti Bond Solo Plus, Fortify, Fortify Plus and control, without any sealer agent. The lowest values of surface r...

Introduction: The aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class II composite resin restorations. Methods: Sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). Class II box-only cavities were prepared in distal aspects of each tooth with gingival margin located a...

The ability to develop a reliable bond between a ceramic restoration and the tooth is a key element in the clinical success with CAD/CAM direct ceramic restorations. Composite resin luting agents are currently the preferred material of choice for adhesively bonding ceramic restorations. They provide several advantages, such as a durable and strong bond to the tooth and ceramic, good color match...

UNLABELLED Toothwear is increasing in prevalence. Traditional treatment methods for moderate or advanced toothwear, such as indirect restorations and crown lengthening surgery, are invasive and destructive of remaining tissues. The 'Dahl technique' has been used to obtain space for anterior restorations and has been modified such that direct composite restorations are placed at increased occlus...

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 and with a reduct...

BACKGROUND In daily clinical practice, esthetics of anterior teeth is a common presenting complaint of patients. OBJECTIVE This case report discusses the management of asymmetric smile associated with unsatisfactory extensive composite restorations and describes a clinical protocol using the direct composite resin for smile enhancement to restore the dental harmony of anterior teeth. METHOD...

OBJECTIVES The purpose of this study was to compare the marginal and internal fit of nano-composite CAD-CAM restorations. MATERIALS AND METHODS A full veneer crown and an mesio-occluso-distal (MOD) inlay cavity, which were prepared on extracted human molars, were used as templates of epoxy resin replicas. The prepared teeth were scanned and CAD-CAM restorations were milled using Lava Ultimate...

STATEMENT OF PROBLEM Microleakage is one of the most frequent problems associated with resin composites, especially at the gingival margin of posterior restorations. Insertion of fibers in composite restorations can reduce the total amount of composite and help to decrease the shrinkage. PURPOSE The aim of this study was to evaluate the effect of polyethylene fiber inserts on gingival microle...

CONTEXT Dental (silver) amalgam is a widely used restorative material containing 50% elemental mercury that emits small amounts of mercury vapor. No randomized clinical trials have determined whether there are significant health risks associated with this low-level mercury exposure. OBJECTIVE To assess the safety of dental amalgam restorations in children. DESIGN A randomized clinical trial...
