    ABSTRACT: The translucency of enamel shade is a crucial property that affects the color of a layered restoration. This study evaluated the translucency of high-, medium-, and low-value resin composites (4 Seasons, Ivoclar Vivadent, Schaan, Liechtenstein) used to replace enamel in stratified composite restoration techniques. The color specimens with 12 mm in diameter and various thicknesses (0.5, 1.0, 1.5, 2.0, 3.0, 4.0 mm) were measured after polymerization on a reflection spectrophotometer over white and black backgrounds to calculate the translucency parameter (TP). The statistical analysis of TP was accomplished using two-way analysis of variance (p < 0.05). Significant differences were revealed by the Tukey's Honestly Significant Difference post hoc test. Translucency of the value composite resins was influenced by the value and thickness. Color of value resin composites was dependent on the background contrast at the evaluated thicknesses. High-value composite resins were more translucent than medium-value composites, which were more translucent than low-value composites. The translucency decreased as the thickness of the specimens increased. The results suggest that special attention should be paid to the thickness of the increment of value composite resins when reproducing translucency of natural tooth enamel.

    ABSTRACT: Dental erosion is a contemporary disease, mostly because of the change of the eating patterns that currently exist in society. It is a "silent" and multifactorial disease, and is highly influenced by habits and lifestyles. The prevalence of dental erosion has considerably increased, with this condition currently standing as a great challenge for the clinician, regarding the diagnosis, identification of the etiological factors, prevention, and execution of an adequate treatment. This article presents a dental erosion review and a case report of a restorative treatment of dental erosion lesions using a combination of bonded ceramic overlays to reestablish vertical dimension and composite resin to restore the worn palatal and incisal surfaces of the anterior upper teeth. Adequate function and esthetics can be achieved with this approach.

    ABSTRACT: This article presents the essential aspects for understanding and reproducing the color of natural teeth with the use of direct resin composite. Fluorescence and opalescence are discussed, with special emphasis on counter-opalescence, which is primarily responsible for the appearance of an orange discoloration at the mamelon dentin tips and incisal edges of anterior teeth. The dynamics of color in natural teeth in relation to age is also discussed, focusing on the age-related changes that occur in enamel, dentin, and pulp. Further, it is demonstrated how to reproduce the esthetic features of natural teeth using latest-generation direct resin composites.

    ABSTRACT: Contemporary adhesive restorations allow clinicians to deliver minimally invasive, functional, and aesthetic treatment for compromised dentition in the anterior and posterior regions. Part 1 of this article discussed the state-of-the-art relating to composite restorations, both in situations deemed to be relatively uncomplicated and those that are more complicated. This second part discusses the clinical protocol for the placement of direct composite materials as well as the tooth preparation considerations that must be addressed when providing minimally invasive treatment options.

    ABSTRACT: Coronal fractures must be approached in a methodical and clinically indicated way to achieve successful restoration. One option for treatment is reattachment of the dental fragment. Reattachment creates a very positive emotional response in the patient and simplifies the maintenance of the patient's original occlusion. This article discusses dental fragment reattachment techniques and presents clinical cases of coronal fracture involving enamel, dentin, and pulpal exposure.
