Summary: Restoration of the endodontically
treated teeth is a controversial topic in restorative dentistry, since many options exist to restore
whole or partially dental crowns. The option for treatment is not selected based on a precise
diagnosis of the state of the dental remanent and differences between anterior and posterior teeth
are not evaluated. Therefore, a classification of the extension defects of endodontically posterior
teeth (EPT) is presented. This classification is based on 4 specific variables: vertical height and
walls distribution of supragingival remaining coronal tooth structure or core, diameter and root
canal depth, and the distance of floor pulpar chamber and the root furcation. The correct
application of this classification can help the operator to choose the best treatment option for the
reconstruction of EPT, also this classification can help investigators to reach more organized
results in future investigations on the reconstruction of EPT. Key words: Post and core. Endodontic.
Diagnostic characteristics.
