Dentistry is all about cosmetics. While fabrication artificial/prosthetic teeth, color shade match is one of the most important parts which is given least importance and time. Traditionally and till very recently, shade match procedure involved simple comparison of the patient’s tooth color with a tooth color shade guide having a specimen of all the colors available for human tooth. The accuracy of color determination using just a simple shade match is questionable. The color selected by this method can vary sharply depending on the illumination of the room, type of light in the room(sunlight/artificial), the color of artificial light(white/yellow), the time of the day during which the shade is determined and of course the errors caused by human eye.
This often leads to a color mismatch when the final teeth are ready. Although there have been standard guidelines devised for shade determination, following then is cumbersome, so hardly used in a day to day clinical practice.
To overcome these limitations, digital shade guides have been invented. These measure shade digitally and all the limitations associated with manual shade determination has been solved. The process is simple. After an initial calibration of the devise, the devise is simply placed on the teeth. It emits light using Led”s and after a beep the correct shade flashes on the screen.

This devise was invented by a company called Vita and the devise is called “Vita Easy Shade Master” It is a very recent addition to our highly technical and modern practice.
We at Dr. Garg’s Multispeciality Dental Centre introduced it to our practice about an year ago and it has made shade determination easy and very quick. Previously the final prosthesis made had to be often sent back to the laboratory for shade corrections particularly in cosmetic dentistry cases but with Vita Easy shade master there is no longer a fear in the mind whether the color of the final prosthesis will match the patient’s natural tooth color. Results are great and is a must for any cosmetic dental practice.
