Detection of Tooth Color Before and After Bleaching Using an Electronic Device.

The purpose of this article is to present a new computerized technique for evaluating tooth color before and after internal bleaching. Internal bleaching is a common and relatively safe procedure, from which results can be easily evaluated by both the dentist and the patient. Clinically, evaluation of the tooth color before, during and after internal bleaching is usually completed by using a color scale and comparing the shade to that of the tooth. However, since in some cases the bleaching results are not obvious, this method has limited value for complicated cases and especially for dental research. The case presented here demonstrates the digital color evaluation process of a tooth going through all phases of internal bleaching. The detected color is presented as the color scale numbers and can easily be saved for follow-up. Those results are presented on the device screen for the all-labial surface and also separately for the incisal, middle and cervical areas. This digital method for color detection can easily be used at every dental clinic as a validated dental record for the bleaching process. This method can also be used for dental research that evaluates the efficacy of bleaching techniques. The esthetic results can be verified easily and precisely.
