Body
Aim : To assess the clinical use of 2 cone beam computed tomography (CBCT) machines (Next
Generation i-CAT and Accuitomo 3D FDP) within one maxillofacial imaging unit.
Method : Data relating to all CBCT scans performed in the period 01/01/2010 to 31/12/2010
was collected retrospectively including patient age and gender, indications for the scan, CBCT
machine used and details of exposure factors.
Results : 705 CBCT scans were performed during the period of the study, 596 (85%) using the
Accuitomo and 109 (15%) using the i-CAT.
Within this study the commonest clinical indication for a CBCT scan was the assessment of
impacted teeth (347 scans [49%]), all of which were performed on the Accuitomo; 231 related
to impacted lower third molars, thus 66% of all impacted teeth under assessment were third
molars, accounting for 33% of all CBCT scans performed during the study period.
With regards to the i-CAT Next Generation machine the most frequent clinical indication for a
scan was found to be pre-operative assessment prior to implant placement.
Of note 203 scans (29%) were performed on patients aged less than 20 years; 30 (4%) were
performed on 0-9 year olds, 3 using the i-CAT and 27 using the Accuitomo.
Conclusions: The complete data set demonstrates the range of clinical applications imaged
using a small field of view machine (Accuitomo) and a large field of view machine (i-CAT). The
information highlights the age range of patients involved, and significantly 4% involve children
less than 10 years known to be at greatest risk from radiation.
