Abstract
Background and aims. The aim of this study was to evaluate the intra- and inter-examiner reliability and reproducibility
of linear measurements on cone-beam computed tomography (CBCT) images made by calibrated radiologists and periodontists.
Materials and methods. The alveolar ridge dimensions were measured on selected CBCT images by two calibrated
radiologists and two periodontists. Intra- and inter-examiner reliability was evaluated by intra-rater and intra-class correlation
coefficients (ICCs).
Results. Intra- and inter-examiners ICCs obtained with the different methods showed almost perfect matches. The results
demonstrated high examiner reproducibility for linear parameters of alveolar ridges on CBCT images in presurgical implant
site assessments.
Conclusion. The alveolar ridge dimensions provided by the radiologists might be useful for the periodontists. The measurements
with small differences were related to the experience and skills of the examiner, inclination measurement, selection
of the exact level of the alveolar crest and the ability to detect the exact anatomic borders on CBCT images.
