Impact Of Digital Photography & Conventional Method On The Accuracy Of Dental Shade Matching In The Esthetic Zone

Study Overview
=================
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

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: group 1 Color matching using Vita 3D master<br>Outcome Name: Color Matching measured by : Modified (USPHS) criteria | Device: Vita 3D master shade guide<br>* Alpha (A)Perfectly matched Beta (B)Not perfectly matched Charlie (C)unacceptable Determent by 10 observers<br>* Other names: Conventional shade matching;|
| Experimental: group 2 Color matching using digital photography<br>Outcome Name: Color Matching measured by Digital Photography using (Photoshop) Software: 0 to 1: no difference in perception 1 to 2: only perceptible to a trained observer 2 to 3.5: perceptible difference 3.5 to 5: marked difference | Device: Digital photography using software Photoshop<br>* 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.<br>|
