Comparison of Digital and Conventional Radiography In Evaluating Horizontal Alveolar Bone Loss

Abstract

Background: The purpose of this study was to evaluate and compare the efficacy of digital and conventional radiographic methods in diagnosis of horizontal alveolar bone loss. Materials and Methods: In this diagnostic study 48 radiographs of 104 teeth with periodontal disease that exhibited horizontal alveolar bone loss were obtained by digital and conventional radiography technique in Zahedan faculty of dentistry in 2007. The depth of intrabony defects was determined by linear measurement analysis of radiovisiography (RVG) and coolis. The distance from cemento enamel junction (CEJ) to the alveolar crest was assessed intra-surgically. The comparison between RVG measurement, conventional radiographic measurements and intrasurgical estimates were performed using paired t-test and P
