Tooth Crown Discoloration Caused by Endodontic Treatment

The color change of endodontically treated teeth is a common concern in clinical practice. The objective of this study will be to evaluate, in vivo, the color change (ΔE00) caused by endodontic treatment. A observational retrospective study will be conducted to evaluate the ΔE00 of anterior (incisors and canines) and posterior (premolar) teeth treated at a private clinic, regardless of technique, treatment time and sealer used. In this study the ΔE00 will be evaluated using the measurements obtained in the homologous tooth (without endodontic treatment) versus the measurement obtained from the tooth treated endodontically. The values of ΔE00 obtained for each sealer, cut and time will be analyzed by multifactorial analysis to verify associations of the outcomes with the ΔE00.
