In Plane Sight: Assessing Root Canal Length Using three-dimensional X-ray Imaging; A Pilot Study, Thomas Noble-Campbell

The aims of this study were to 1) evaluate the accuracy of canal lengths measured using two three-dimensional X-ray measurement approaches and 2) provide the first report on the canal configurations of Māori lower first molars. Fourteen extracted New Zealand European and Māori lower first molars were analysed. Canal lengths and configurations were recorded using each approach. No significant difference was observed between measurement approaches. Compared to actual root canal length, one method (axial view) had a higher proportion of measurements accurate within ±0.5mm. Māori first molars presented most commonly with four canals. Vertucci type IV and II configurations were most common in the mesial (75%) and distal canals (50%), respectively. Axial canal length measurements may be more clinically accurate in mandibular first molar teeth.
