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. |
