Abstract

Comparing the Accuracy of Cone Beam Computed Tomography,Digital Intraoral Radiography and Conventional Intraoral Radiography in the Measurement of Periodontal Bone Defects

Highlights

Detection of periodontal disease is important to prevent tooth loss.(1) The incidence of this disease has increased (2) and has been estimated to be about 30% in the western countries. (3) Three-dimensional (3D) observations and the ability to measure the different aspects of alveolar bone are important in the detection of periodontal disease
Previous studies have revealed that the height of alveolar bone is more useful in determining the treatment protocol and prognosis compared with the measurements from the CEJ or the depth of intra osseous lesions.(4) different diagnostic techniques including probing and radiologic methods such as panoramic, bitewing and periapical radiography have been introduced, but providing a two-dimensional view is the major limitation of these methods.(5, 6)
Cone beam computed tomography (CBCT) is being used in many dental fields.(6) Several studies have evaluated the accuracy of this modality.(1-5, 7, 8) all these studies have shown the appropriate accuracy of this method, but the small sample size is their major limitation

Summary

Introduction

Detection of periodontal disease is important to prevent tooth loss.(1) The incidence of this disease has increased (2) and has been estimated to be about 30% in the western countries. (3) Three-dimensional (3D) observations and the ability to measure the different aspects of alveolar bone are important in the detection of periodontal disease. Previous studies have revealed that the height of alveolar bone is more useful in determining the treatment protocol and prognosis compared with the measurements from the CEJ or the depth of intra osseous lesions.(4) different diagnostic techniques including probing and radiologic methods such as panoramic, bitewing and periapical radiography have been introduced, but providing a two-dimensional view is the major limitation of these methods.(5, 6). This study was designed to evaluate the accuracy of CBCT, intraoral digital radiography and intraoral conventional radiography in the detection of periodontal infra-bony defects. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. CBCT technique showed the highest accuracy in the measurement of periodontal bone defects compared with digital and conventional intraoral radiography
