Polychromatic Composite and Resin Infiltration Restorations in the Esthetic Zone: A Five-year Clinical Report.

OBJECTIVE: This case report describes the use of a combination of a polychromatic resin composite restoration and resin infiltration to achieve a satisfactory esthetic outcome that has lasted over five years. CLINICAL CONSIDERATIONS: The patient's primary complaint was a desire to replace an existing stained resin composite on the facial and mesial surfaces of the maxillary left central incisor, and a white spot on the facial surface of the maxillary right central incisor. After clinical evaluation, the patient was offered either replacement of the restoration with a polychromatic restoration simulating a white spot, or a combined treatment with polychromatic composite and resin infiltration restorations, which was recommended. The patient selected the latter treatment. A putty matrix was fabricated, and a quick mock-up was done using various enamel and dentin shades of resin composite to determine proper material selection. The previous resin composite restoration was removed, and layers of new dentin, body, and enamel composite were placed. An interproximal matrix was used in order to provide ideal contour and contact. Finishing and polishing procedures were performed. The maxillary right central incisor was treated with resin infiltration in order to subdue the white spot on the facial surface. CONCLUSIONS: Polychromatic resin composite and resin infiltration restorations to replace a stained restoration and mask a white spot can achieve desired results in the esthetic zone and maintain them for five years.
