Root canal length measurement of molar teeth using cone-beam computed tomography (cbct): comparison of two-dimensional versus three-dimensional methods

Selen Nihal SisliOrhan Gülen

Purpose: This study aimed to evaluate the validity of 2-dimensional (2D) and 3-dimensional (3D) cone-beam computed tomographic (CBCT) root canal length measurements of molar teeth compared with actual root canal lengths and the influence of canal curvature on the accuracy of CBCT measurements.

Materials and Methods: Seventy root canals of 24 molar teeth were scanned using CBCT, and the root canals were categorized as; ‘straight/curved,’ ‘highly curved,’ and ‘multiple curved.’ The 2D measurements were performed within a suitable slice between the major foramen and the corresponding cusp. The 3D measurements were performed within the slices in regular intervals of axial planes in between the same reference points. The reproducibility and reliability of the methods were analyzed by intraclass correlation coefficient. Differences between the actual and CBCT root canal lengths were evaluated by chi-square and McNemar tests if the measurements were within acceptable limits of ±0.5 mm.

Results: Both methods were found to be reproducible and presented excellent reliability. However, the 3D method was significantly more accurate, with an 85.7% frequency of measurements within acceptable limits (p<0.05). In ‘multiple curved’ root canals, the 3D method presented more reliable measurements than the 2D method. For ‘straight/curved’ root canals, the 2D method gave results significantly closer to the actual root canal length in comparison with ‘highly curved’ root canals (p<0.05).

Conclusion: The 3D measurements are more accurate than 2D measurements. If an already existing CBCT is present, it could be an alternative method for predetermination of root canal lengths in molar teeth.
