introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...

introduction: this in vitro study investigates the marginal and internal fit of indirect class ii composite restorations. two different processes for chair-side restorations were compared. in group a, the restorations were fabricated using cad/cam technology (cerec, sirona, germany, bernsheim) and in group b they were made by hand (grandioso inlay system, voco gmbh, germany, cuxhaven). methods:...

OBJECTIVES To compare re-treatment choices for MOD amalgam or resin composite restorations with or without cusp fracture among dentists in Kuwait. METHODS A random sample of 158 dentists completed a questionnaire designed to obtain socio-demographic, educational and work-related information and their choices for re-treatment of four scenarios of failed restorations on lower first molars: 1. M...

Background: Modern restorative dentistry offers many methods of restoring the carious teeth. The advancements in adhesive dentistry have brought significant changes in the treatment of caries. Dental composite formulations have been continuously evolving ever since BISGMA was introduced to dentistry by Boven in 1962. The composite materials can be divided into direct and indirect resin composit...

When an esthetic restoration with minimal tooth reduction is desired, for example in patients with uncomplicated tooth fractures, composite partial coverage crowns may be a therapeutic option. The indirect composite restoration allows restoration of the original tooth anatomy, function, and esthetics to be reproduced while preserving tooth structure. The use of composite partial coverage crowns...

OBJECTIVE The aims of this study were to evaluate the tensile bond strengths between indirect composites and dentin of 3 recently developed self-adhesive resin cements and to determine mode of failure by SEM. MATERIAL AND METHODS Exposed dentin surfaces of 70 mandibular third molars were used. Teeth were randomly divided into 7 groups: Group 1 (control group): direct composite resin restorati...

OBJECTIVE This article presents a case report of restoration of anterior teeth using an indirect technique with composite veneers in order to restore the dental anatomy and to provide aesthetic and function of anterior teeth. MATERIALS AND METHODS A treatment of upper anterior teeth with indirect micro-hybrid composite restoration was proposed to a 40-year-old woman with old discolored and fr...

objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...
