Özet:

 


Objective: The purpose of this
study is to investigate possible effects of the slice thickness on volume
estimations with CBCT.



 

Materials
and Methods: Intraosseous cavities representing bone defects on femoral
condyles of bovines were scanned by CBCT. Consecutive slices at 0.1 mm, 0.2 mm,
0.3 mm, 0.4 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm thickness were used to
estimate the volumes of the cavities using Cavalieri principle of stereological
methods then compared with the volumes obtained by Archimedean principle.



 

Results: The volumes estimated
by Cavalieri principle in 0.1, 0.2, and 0.3 mm thickness slices were consistent
with the volumes obtained by Archimedean principle (p>0.05). For all the
defects on the CBCT images, the volumes of the defects which were calculated
with Cavalieri principle in 0.1, 0.2, and 0.3mm slice thickness were found to
be consistent with the actual volumes, however, the volumes that were
calculated in 0.4 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4mm, and 5 mm slice thickness
were found to differ from the actual volumes. 



 

Conclusion:
When
volume calculations were made by Cavalieri principle, the thinnest slice section
should be chosen to make calculations consistent with actual volumes.
