T he superior physical properties of composite resins have aroused the possibility of their use beyond the accepted indications for acrylic resin and silicate cement. The literature has suggested the use of composite resin for Class I,‘m4 Class II,” and Class IV39 * restorations. Other reports advocated the use of composite resin or tested the influence of pins on the physical properties of com...

Traumatized anterior teeth with subgingival fractures of the crown and root can be restored successfully after orthodontic extrusion. A technique is described which involves the use of a localized fixed appliance made of rectangular wire. The appliance is fabricated in the laboratory prior to bonding to the teeth with composite resin. The simple design of the appliance makes it easy to manage a...

Background: The newly introduced self-adhering flowable resin-composites decrease the required time for application by incorporation of an acidic adhesive monomer, thus reducing the number of steps, but its bonding is still uncertain. The aim of this study was to evaluate the interfacial microscopic examination and chemical analysis at the resin-dentin interface of a self-adhering flowable resi...

Objectives: Treatment of chipped or fractured porcelain with composite resin is considered as an economic treatment for minor fractures in ceramics. The aim of this study was to evaluate the effect of different ceramic surface treatments on bond strength of methacrylate-based and silorane-based composite resin to IPS Empress 2. Methods: Sixty IPS Empress 2 ceramic discs were fabrica...

Background: New materials that are introduced in operative dentistry can potentially have orthodontic applications. One of the most important advances in the dental material field is the application of nanotechnology to resin composites. Recently, new fillers with size ranging from approximately 5-100 nm have been developed. These materials could thus be considered as precursors of nanocomposit...

abstract background and aim: one of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. considering the diverse composition of available ...

THE EFFECT OF THE BLUE LIGHT DIODE LASER ON SHEAR-PEEL BOND STRENGTH OF ORTHODONTIC BRACKETS WITH VARYING CURING TIME AND DISTANCE Kamran Shaikh, DDS June 17,2010 Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in ha...

Teeth that have been endodontically treated often have little coronal tooth tissue remaining and, as such, require a post to retain the core and restoration, and need to be restored by crowns1,5,9. Metal posts are most commonly used due to their favourable physical properties and excellent biocompatibility4,8. With recent advances in ceramic technology, the all-ceramic crown has become more pop...
