A smartphone application with a gray card for clinical shade selection: A technique

Area of Science:

• Dental Materials Science
• Color Science in Dentistry
• Clinical Restorative Dentistry

Background:

• Accurate shade selection is crucial for esthetic dental restorations.
• Challenges exist in objective color measurement and communication in dentistry.
• Traditional shade guides can be subjective and lack precision.

Purpose of the Study:

• To present a novel technique for objective clinical shade selection.
• To evaluate the utility of a smartphone application and gray card for shade matching.
• To improve color communication between dentists and dental laboratory technicians.

Main Methods:

• Utilized a smartphone application (Snapseed) for image analysis.
• Employed a standardized gray card for color calibration within clinical photos.
• Documented the shade selection process for definitive dental restorations.

Main Results:

• The described technique offers a reproducible method for capturing tooth shade information.
• Smartphone image analysis combined with a gray card provides a more objective basis for shade selection.
• Facilitates clearer communication of shade data to dental laboratories.

Conclusions:

• Smartphone technology integrated with a gray card can enhance the accuracy of clinical shade selection.
• This approach offers a practical and accessible tool for improving esthetic outcomes in restorative dentistry.
• Improved shade communication leads to more predictable and satisfactory results in dental laboratory fabrication.
