Abstract
Background: The detection and accurate assessment of periodontal disease is important for the determination of the tooth prognosis, the treatment, so the radiographic assessment of the alveolar bone loss is essential for providing information about the pattern & extent of alveolar bone loss; Digital radiography provides the ability to enhance images and make direct measurements. On the other hand CBCT most important advantage is providing unique 3D images demonstrating features and used for diagnosis and treatment plans, but till now, its use in periodontology not well-reviewed and documented, as there is few number of studies searched about the role of CBCT in periodontology. Aim: Is to compare digital radiography with CBCT in the detection and measurements of different simulated bone defects. Material and methods: dry jaws with simulated bone defects were imaged by CBCT and Digital radiography the data and measurements were collected and compared with the gold standard dry jaws. Results: There was no statistically significant difference between the CBCT and Digital radiography in detecting the presence of the periodontal defects but CBCT more accurate in measuring and detecting the types of periodontal bone defects and furcation involvement, matching the real gold standard data. Conclusion: Non inferiority hypothesis between CBCT and Intraoral Digital Radiography in detecting the presence of the bony defects and superiority of CBCT in the linear measurements and in the detection of the different types of bony defects and furcation involvement
