Clinical evaluation of different types of teeth in in-office whitening.

The general analysis of the results indicates that the tooth type affects the response to the whitening treatment, both in relation to the esthetic benefit and the occurrence of tooth sensitivity. It was observed that mandibular incisors reach the degree of chromatic saturation before canines and premolars, in addition to presenting greater bleaching sensitivity. Personalizing the treatment, based on prior knowledge of the degree of saturation, anatomical factors, and the risk of sensitivity, can provide considerable advantages in the whitening technique.
