Accuracy of Dental Shade Selection in the Aesthetic Zone

Brief summary

The aim of this study: Is to evaluate the accuracy of digital photography in optimizing shade matching when compared to conventional method of shade selection.

Detailed description

Randomized control trial, 2 groups will be included. Group 1: Color matching using Vita 3D master, using modified (USPHS) criteria Group 2: Color matching using digital photography using (Photoshop adopt) the assessment will be through a questionnaire for the patient satisfaction outcome using Visual analogue scale

Interventions

DEVICEDigital photography using software Photoshop

When taking the image, a gray card is used for subsequent exposure calibration in Adobe Camera Raw (which is packaged with Photoshop). * Images are then opened into Photoshop. * The INFO panel must be open. * Click on the small eyedropper in the Info panel window and click on ''Lab Color. * Place the mouse over the center of the tooth to be measured for L value. * Click on the HSB Color option, which stands for hue, saturation, and brightness.
