Abstract
Abstract—background: the aim of the study was to compare the volume of the tooth in-vitro between four cone beam computed tomography (CBCT) scanners and one multi-slice computed tomography (MSCT) system.
Materials and methods: 42 teeth in-vitro was scanned with four CBCT systems (Accuitomo 3D, Vatech Imlagraphy, NewTom 3G, CRANE 3Dx) and one MSCT scanner (Philips Brilliances 16). 3D models were created from the six systems. The reference (gold standard) model was obtained with a high resolution laser scanner. The scanning results from the six systems were compared with the gold standard in volume.
Results: The laser-scan sample volume was statistically significantly distinct from the MSCT-scan volume (P<0.05). There was a statistically significant difference between the laser-scan teeth volume and CBCT-scan volume (P<0.05). There was a statistically significant difference between the MSCT-scan teeth volume and CBCT-scan volume (P<0.05). The measurements of the CBCT-scanned samples deviated from those of the laser-scanned teeth volumes by 5.97%, 6.19%, 5.95%, 5.61% for the Accuitomo, Vatech Imlagraphy, NewTom, CRANE 3Dx, separately. The measurements of the MSCT-scanned samples deviated from those of the laser-scanned teeth volumes by 10.98%.
Conclusion: The results showed that the volume of the teeth scanned by MSCT and CBCT increased comparing to that of laser scan. The deviation of the volume measurement of MSCT-scan models tended to be larger than that of CBCT-scan models comparing to the gold standard.
