EndoTooth 21 Internal Resorption

EndoTooth 21 Internal Resorption

• Upper incisor (21 ISO notation) with internal resorption
• Accessed and intact variant
• With or without pulpal tissue
• Transparent or opaque
• Difficulty: 4/5

Upper incisor with one root canal and specific pathology – excessive internal resorption. In the middle third of the canal there is a middle-sized resorption cavity that does not perforate the outer surface of the tooth. In the apical third there is a more extensive resorption cavity that perforates the root and communicates with the periodontium. The root canal itself is relatively wide and oval in cross-section. The apical diameter is 0.4 mm.
