Evaluation of the Effect of Apical Lesion on Mucosal Thickening and Thickness of Apical Bone Using Limited Cone‑Beam Computed Tomography

Abstract

Objective: The purpose of this study was to evaluate the effect of periapical lesion size on the degree of mucosal thickening of maxillary sinus and thickness of apical bone using cone‑beam computed tomography. Materials and Methods: In Group 1 (teeth with apical lesions), diameter of apical lesion, width of apical bone, thickness of Schneiderian membrane; for Group 2 (teeth without apical lesions), width of apical bone in long axis of root and thickness of Schneiderian membrane were measured on coronal and sagittal images. Results: Mann–Whitney U‑test revealed no significant difference between two groups regarding mucosal thickening and apical bone measurements (P > 0.05). Wilcoxon signed‑rank test showed no significant difference between the measurements in sagittal and coronal slices (P > 0.05). Conclusion: Results of the present study showed that Schneiderian membrane near the maxillary premolars and molars with apical lesions is not significantly thicker compared to teeth without apical lesions.
