Body
Objective
To investigate observer performance and confidence of CBCT compared with conventional
radiography for the assessment of retained canines with eruption disturbances.
Material and methods
100 patients with maxillary canines with eruption disturbances were examined following a
protocol with panoramic and two intraoral radiographs and with CBCT-images. Radiographic
examinations were performed in Malmö, Sweden and Vilnius, Lithuania. Five specialists in
oral and maxillofacial radiology assessed the radiographs in two sessions; (A) panoramic and
intraoral radiographs and (BI) panoramic and CBCT radiographs. The following features of the
retained canines were to be assessed:(I) position of crown and root, (ii) apical status (open
or closed), (ii)root anatomy (curve), (ii) size of the follicle surrounding the crown, and (iv)
presence and amount of root resorption of neighbouring teeth. The observers rated their
confidence for each feature on a visual analogue scale (VAS). Time used for assessment was
recorded.
Results
There was no difference between the observers‘ assessments on important features such as root
anatomy and root resorption of neighbouring teeth obtained with the panoramic and intraoral
radiographs versus panoramic and CBCT radiographs.. In general, the five observers were more
confident (p< 0.05) in their assessments when having access to CBCT-images, but the assessments
took significantly longer time (p
