Abstract
Objective: To evaluate the accuracy of digital photography and spectrophotometer in optimizing shade matching when compared to conventional method of shade selection. Materials and Methods: A total of 9 patients, requiring restorations in the esthetic zone, were included in this study. Each patient received 3 crowns representing 3 groups according to the different shade matching method used. group (V3D) as a control group: VITA 3D-master shade guide, group (VE) as 1st intervention: VITA Easy shade V spectrophotometer and group (D) as 2nd Intervention: Digital photography with Adobe Photoshop software. Results: According to the modified USPHS criteria, results of comparison between the three groups are presented in Table (3) and Figure (107). Six restorations of group (V3D) showed (66.74%) Alpha score, while three restorations showed (33.3%) Bravo score.
All restorations of group (D) showed (100%) Alpha score. While for restorations of group (VE): two restorations showed (22.2%) Alpha score, three restorations showed (33.3%) Bravo score and four restorations showed (44.5%) charlie score. All groups showed (0%) Delta score.
