Popis: | Aim The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) in assessing maxillary molar furcation involvement (FI). Materials and Methods Fifteen patients with generalized chronic periodontitis after initial therapy were recruited. CBCT was performed in maxillary molars with probing pocket depths of ≥6 mm and advanced FI, and CBCT images were analysed. Furcation surgery was performed in 20 maxillary molars. Lastly, intra-surgical FI assessments were compared with CBCT-based data. Results Intra-surgical findings confirmed 82.4% of the CBCT data, with a weighted kappa of 0.917. The agreement between both assessments was the highest in buccal furcation entrances, followed by distopalatal and mesiopalatal furcation entrances. Of the four parameters tested of detailed root anatomy and furcation morphology, the mean length of the root trunk and the width of the furcation entrance revealed by CBCT were consistent with their respective intra-surgical values (p > 0.05). Horizontal bone loss and vertical bone loss were underestimated by CBCT relative to their respective intra-surgical classifications (p ≤ 0.05). Conclusions Cone-beam computed tomography images demonstrate a high accuracy in assessing the loss of periodontal tissue of the FI and root morphologies in maxillary molars. |
