Comparison of Cone-beam Computed Tomography and Periapical Radiography to Determine the Proximity of Periapical Lesions to Anatomical Structures in Premaxillary Area prior to Surgical Endodontics: A Clinical Study

AIM: In the anterior maxillary region when periapical (PA) surgery is contemplated, knowledge of relation between root apices and lesion, spatial relationship of tooth root to adjacent anatomical structures is essential. The aim of this study was to compare cone-beam computed tomography (CBCT) and PA radiography to determine the proximity of PA lesions to anatomical structures in the premaxillary area for decision-making before apical surgery. MATERIALS AND METHODS: Twenty subjects were selected. Three endodontists viewed PA radiographs and CBCT images. These observers (1) determined proximity of lesion to anatomical structures and (2) made decisions on treatment based on each imaging modality. Chi-square test was used to check the relationship between the treatment plans given by PA radiographs and CBCT images. Reliability of the observations was evaluated using intraclass correlation (ICC). RESULTS: Significant difference was noted in the treatment plan selected by the observers using the two modalities (p < 0.05). CONCLUSION: After the lesions were observed with CBCT, there was an increase in the number of teeth involved with the lesion. A change in the observer's treatment plan was recorded after viewing the CBCT scans. HOW TO CITE THIS ARTICLE: Sheth K, Kapoor S, Daveshwar S, et al.
