AbstractIntroduction: The purpose of the present study was to evaluate the thickness and the anatomic characteristics of the Schneiderian membrane and cortical bone using limited cone beam computed tomography (CBCT) scannning in patients referred for planning of apical surgery of maxillary molars. Methods: This controlled study included 2 cohorts of patients (n = 50 for each group). For patients in group 1 (with apical pathology), 3 measurements in millimeters were performed using coronal and sagittal CBCT slices: the dimension of the apical lesion in the axis of the root, the width of the cortical bone in the axis of the root, and the thickness of the Schneiderian membrane perpendicular to the underlying cortical bone. For the analysis of CBCT scans of group 2 (without apical pathologies), 2 measurements were performed using coronal and sagittal CBCT slices: the width of the cortical bone in the axis of the root and the thickness of the Schneiderian membrane perpendicular to the underlying cortical bone. Results: For group 1, the periapical lesions evaluated measured between 0.27 and 7.41 mm in diameter, the apical bone separating the apical lesions from the maxillary sinus ranged from 0.13 to 7.83 mm, and the dimensions of the Schneiderian membrane ranged from 0.25 to 13.98 mm. The apical bone was generally thicker in patients with periapical lesions. Regarding the dimensions of the Schneiderian membrane, the values were statistically significantly higher for the patients in group 1 compared with group 2. Conclusions: The study showed that the Schneiderian membrane in the vicinity of roots with apical lesions tends to be significantly thicker when compared with the roots of teeth without apical pathoses.
