Introduction: The aim of this study was to evaluate the accuracy and reliability of cone beam computed tomography (CBCT) volumetrically rendered (VR) and multiplanar reconstructed (MPR) images from for measuring buccal and lingual periodontal alveolar bone levels. Methods: Three dry human skulls with 215 sites were scanned with CBCT unit. Measurements were made on each tooth using VR and MPR images, from the cusp tip or incisal edge to the cementoenamel junction (CEJ) and from the CEJ to the alveolar bone margin along the long axis of the tooth. The accuracy of the CBCT measurements were determined by comparing the means, standard deviations (SDs), mean differences, and SD differences of the VR and MPR measurements with those of direct measurements made on the dry skulls as the gold standard (GS). Results: The means ± SDs of the GS, MPR, and VR measurements were 4.64 ± 1.94 mm, 4.21 ± 1.86 mm, and 4.1 ± 1.86 mm, respectively. There were significance differences between the GS measurements and both MPR and VR measurements (P < 0.05). Results of a GS-MPR paired samples test showed a mean difference of 0.43 mm and a SD difference of 0.77 mm, whereas those of a GS-VR paired-samples test showed a mean difference of 0.540 mm and a SD difference of 0.98 mm. Conclusions: Although there were significance differences between the GS measurements and both MPR and VR measurements, MPR is more accurate and reliable than VR for measuring the levels of buccal and lingual periodontal alveolar bone. However, the difference detected is not clinically significant. Thus, CBCT can accurately and reliably assess the buccal and lingual periodontal alveolar bone levels.
