Objective: The objective of this study was to analyze the correlation between cone-beam computed tomography (CBCT) measurements and intrasurgical measurements of intrabony periodontal defects. Materials and Methods: Thirty-two patients with intrabony defects, who underwent periodontal therapy and were advised for surgical therapy, were included in this study. Diagnostic images were obtained by periapical radiographs and CBCT before the surgical procedure. The distance from the cementoenamel junction to the base of the periodontal defect (CEJ–BD), the distance from the crest of bone to the deepest point of the defect, and mesiodistal (M-D) width of the periodontal defect were measured on CBCT and periapical radiographs during the surgical procedure. The faciolingual width of the defect was only measured on CBCT images during the surgical procedure. The linear measurements obtained during the surgical therapy were compared with that obtained by intraoral radiographs and CBCT imaging. Results: The M-D width of the defect measured during the surgical procedure was similar to that measured on the periapical radiograph. The distance of CEJ to BD and the distance from the crest of bone to the deepest point of the defect measured on the periapical radiographs were less than that of intrasurgical measurements. No significant difference was noted regarding the CBCT measurements of the faciolingual width and M-D width of the defect when compared with the measurements obtained during the surgical procedures. A significant difference was noted in the CBCT measurements from the CEJ to BD and the distance from the crest of bone to the deepest point of the defect when compared with the intrasurgical measurements. Conclusion: CBCT may lend comparatively discriminative dimensions of the periodontal defect similar to that of intrasurgical measurements.
