The VITA Classical Shade Guide is an essential tool for dental professionals in accurately determining tooth shades for restorative procedures. This comprehensive shade guide comprises sixteen distinct color categories, each represented by a range of shades denoted by letters and numbers, from A1 to D4. These categories encompass a spectrum of natural tooth colors, including reddish-brownish, reddish-yellowish, grayish, and reddish-grayish tones. To ensure precise color matching, the guide should be held at an angle of approximately 25-30 cm from the patient’s tooth, with the arm comfortably bent.

The guide offers valuable tips for optimal shade determination. Performing the assessment prior to tooth preparation is advised, as dehydration during preparation can alter the perceived shade. Natural daylight or standardized daylight lamps (5500K – 6500K) are recommended for accurate assessments, avoiding typical indoor lighting conditions. Creating a neutral-colored environment is crucial, with patients removing any influencing lipstick or cosmetics, and covering brightly colored clothing with a gray cape.

Additionally, the VITA Classical Shade Guide emphasizes the importance of promptly disinfecting the guide after each use, ensuring a hygienic and safe application. The guide’s acrylic components are made of a durable, temperature-resistant material that can be surface disinfected, further enhancing its longevity and usability. For added versatility, the guide can be autoclaved up to 132 °C/270 °F, providing a sterilization option.
