SUMMARY Fractured teeth with both enamel and dentin involvement might be treated with adhesive composite resin restorations. In cases where a perfect color match between the composite restoration and the remaining tooth structure is not achieved, a repair might be carried out to correct the color of restoration. This procedure avoids the restoration replacement, preserving tooth structure without compromising the esthetic outcome.
SUMMARY Rehydration of the tooth remnant and complete polymerization of the composite resin are aspects that should be considered in shade selection of composite resin. This article presents a case series of Class IV restorations performed to evaluate the color match between the composite resin and the tooth remnant. Thirteen Class IV restorations were performed in maxillary central incisors and evaluated according to the period following the restorative procedure: 10 minutes (baseline), 48 hours before and after finishing and polishing, and seven, 14, and 28 days. The color match of the restorations was evaluated by the ΔE values of the tooth remnant (TR) and the composite resin (CR) in each evaluation period using a spectrophotometer. The translucency, luminosity, and saturation were analyzed qualitatively in digital photographs of the restorations. The CR ΔE was statistically similar to the TR ΔE at 14 and 28 days ( p >0.05). The saturation and luminosity of most of the restorations remained unchanged, but there was a greater change in the translucency. The color match of the composite resin in Class IV restorations was observed after 14 days of clinical assessment in this case series.
SUMMARY The aim of this article is to present a case report for the multidisciplinary treatment of anterior tooth fractures with invasion of the biologic width and pulpectomy. Successful esthetic and functional results were achieved by bonding the crown fragment, without any form of preparation or the utilization of intracanal posts.
SUMMARY In some patients with labial white stains involving the enamel and dentin, bleaching associated with a restorative procedure using composites may be an appropriate treatment alternative. Although bleaching makes the teeth and the stain whiter, the staining is less evident and easier to restore. Restorative procedures using adequate composites may then recover the natural optical properties while also providing appropriate mechanical properties, thereby ensuring the longevity of the treatment. In this article, the clinical case of a 9-year-old patient who reported dissatisfaction with her smile because of the presence of hypoplastic enamel staining at the central superior and inferior incisors is reported. The treatment consisted of a bleaching protocol followed by composite resin restorations using the stratification technique. The final esthetic result demonstrated the possibility of obtaining a natural smile with an adequate color and natural-looking restorations, thereby ensuring the esthetics and the patient's functional satisfaction.
