It is a challenge for every aesthetic dentist to determine and replicate the appearance of teeth, as it requires humility, patience and perseverance to mimic natural tooth to its closest sense and form. To provide the patient with an aesthetic restoration the dentist must consider the scientific basis of color as well as the artistic aspect. The shade matching using digital processing techniques gives accurate results by eliminating subjective errors. In this work, the captured image is processed through MATLAB in PC and the exact shade of tooth is determined.
