Cone Beam Computed Tomography versus Intraoral Digital Radiography in Detection and Measurements of Simulated Periodontal Bone Defects Diagnostic Accuracy Study

Abstract

Detection and accurate assessment of periodontal disease is important to determine the tooth prognosis and treatment. Radiographic assessment provides information about the pattern and extent of the alveolar bone loss. Digital radiography has ability to enhance images and make direct measurements. CBCT provides unique 3D images used for diagnosis and treatment plans, but its use in periodontology not well-reviewed as there is few number of studies searched about the role of CBCT in periodontology. We compare digital radiography with CBCT in the detection and measurements of different bone defects. Dry jaws with simulated bone defects were imaged by CBCT and Digital radiography the data and measurements were compared with the gold standard dry jaws. Our study shows 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; showing 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 & furcation involvement.
