Abstract

Abstract: Objective: To assess the value of CBCT in the diagnosis of chronic periodontitis. Methods: Included in this study were twenty patients with chronic periodontitis who took bothfull mouth CBCT and the periapical radiograph of posterior teeth. They also received periodontal clinical examinations. The alveolar bone resorption at the medial-distal and lingual-buccal sites of 276 posterior teeth were measured by CBCT and periapical radiographs. Thecomparison between these two methods was done. Results: There was no significant difference in measuring the amount of resorption between CBCT and the clinical examination. However, the bone loss measured by periapical radiographs was less than those measured by CBCT and clinical examination.There was significant difference in the measured alveolar bone resorption among CBCT, clinical examination and periapical radiographs. Conclusion: CBCT is more accurate in the diagnosis of chronic periodontitis compared with periapical radiographs.
