Artefacts in Cone Beam CT Mimicking an Extrapalatal Canal of Root-Filled Maxillary Molar
Figure 2
(a) From left to right, axial scans of coronal, middle, and apical root sections suggesting the presence of a third root canal in the palatal root (arrows). (b) Sagittal scans demonstrating that the third canal observed at previous images was an artifact (arrows). Note the presence of hypodense periapical areas on the palatal root.
