The Correlation between Intraorifice Distance and the Anatomical Characteristics of the Second Mesiobuccal Canal of Maxillary Molars: A CBCT Study

Figure 1

Pictures showing the procedure of performing measures on (a) coronal, (b) axial, and (c) sagittal plane. In (a) the horizontal line is made by linking on the reference plane (coronal in this case) the two points referred to the cemento–enamel junction on buccal and palatal aspect; the vertical line is perpendicular to the horizontal one and directed to the root apex (most apical extent). In (b) the distance between different landmarks is taken on an axial plane, approximately at the level of the floor of the pulp chamber. In (c) the horizontal line is made by linking on the reference plane (sagittal in this case) the two points referred to the cemento–enamel junction on buccal and palatal aspect; the vertical line is perpendicular to the horizontal one and directed to the root apex (most apical extent).
