OBJECTIVES In an area of esthetic dentistry such as posterior composites, in which new materials and techniques are being devolved continuously, it is important to confirm that dental students have a clear understanding of the basic principles of clinical application of this knowledge. Considering that the preparation of dental graduates in Spain may be of interest to competent dental authoriti...

The growing demand for esthetic restorations has driven the dentists to provide composite resin restorations even in the posterior class I situations. In these load bearing locations of the teeth, composite resins are subjected to a very thorough biodynamic testing which revealed some of their shortcomings. Persistent postoperative sensitivity has been recognized to be a reason for failure of t...

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 review article is to abridge all the available information regarding the Mechanism of tooth bleaching and their consequences on dental soft and hard tissues structures ,physical properties morphology and color of composite restorations. The controversial reviews regarding the effects of dental bleaching agents were reviewed. Information from the original scientific full pa...

Two composite resins (Ful-Fil ® and X-55®) were placed in the primary molars of 50 children aged 4 to 8 years. A total of 357 restorations were placed in 3 different cavity preparations. The restorations were evaluated by 2 investigators at 0, 6, 12, 24, and 36 months using the USPHS evaluation criteria. At 48 months 130 restorations were available for evaluation. This represents a recall rate ...

BACKGROUND The aim of this longitudinal study was to compare caries incidence in sound approximal surfaces adjacent to newly placed composite restorations with the caries incidence in corresponding surfaces in contralateral teeth without any restorations in contact; and to assess risk factors for dentine caries development on adjacent and control surfaces. METHODS Data from a practice-based s...

Studies to date have assessed wear of composite restorations in primary molars using the United States Public Health Service (USPHS) evaluation criteria. Direct clinical evaluations of 148 Ful-Fil® restorations using the USPHS wear criteria were made at baseline, 6, 12, and 24 months. Quantitative assessments were made by comparing calibrated standard casts with the die stone casts obtained at ...

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:...

The development and reliability of adhesive resin composite systems have offered clinicians a further option for the management of tooth-surface loss. Patients with minimum, moderate, and severe hard tissue wear can be treated based on the application of minimally invasive adhesive composite restorations for posterior and anterior worn dentition. This article presents the "index technique", a n...

objective: the present in vitro study was undertaken to compare the effects of hydrogel and solution forms of sodium ascorbate on microleakage of composite restorations subsequent to a non-vital bleaching procedure with 10% carbamide peroxide. materials and methods: forty-eight sound extracted human maxillary incisors were obtained. following root canal therapy, the teeth were randomly divided ...
