Body
Objectives: To compare diagnostic validity of cone-beam computed tomography (CBCT) imaging
with digital panoramic radiographs for orthodontic initial evaluation.
Materials & Methods: From 20 subjects (age 6-30 years old, 10 males and 10 females), with
a clinically justified need for both CBCT and panoramic images (taken with a maximum time
interval of 6 months), images were collected (Oral Imaging Center, University hospitals KULeuven).
Three observers scored image quality and criteria concerning orthodontic initial evaluation.
The observation was repeated after 4 weeks. The intra- and inter-observer agreement were
evaluated.
Results: CBCT images did not score significantly better than conventional digital panoramic
radiographs concerning image quality. Yet, CBCT provided additional valuable diagnostic information
for initial orthodontic treatment planning. The observer agreement was moderate.
Conclusions: While 2D-panoramic images are commonly used by orthodontists for orthodontic
evaluation, CBCT images have the potential to provide additional valuable diagnostic information.
