Intraoral photographs are the best method to document color matching, interfacial staining, and occlusal patterns. Intraoral color photographs were taken at baseline (before and after restoration placement) and will be taken at each evaluation appointment as a permanent record for subsequent indirect evaluation and later reference. Pre-operative photographs consist of one image of the defect to be restored. Clinical photographs will be high-quality digital images made at an original magnification of 1.5x and will be used principally for reference to document the direct evaluations.
