Comparing the Diagnostic Efficacy of Conventional and Digital Imaging Using Chemically Simulated Periapical Lesions

Abstract

Background: Digital radiography has taken the place of conventional radiography in the field of medical imaging nowadays. The goal of the study is to compare diagnostic efficiency of conventional and digital radiography in vitro.  
Methods: Periapical lesions were prepared chemically using 50% nitric acid in a defleshed cadaver skulls (6 teeth from each skull – 3 maxillary and 3 mandibular). Both conventional and digital intra oral periapical (IOPA) radiographs of the lesions created was taken using paralleling technique at 0 hour, 24 hrs, 48 hrs, 72hrs and 96 hrs. The radiographs taken were compared after assigning different scores for the periapical lesion at each stage by a single oral radiology specialist. The scores obtained were analysed using appropriate statistics.
Results: There was no statistically significant difference between conventional and digital radiographic modalities.
Conclusion : The digital IOPA system can be utilised on a regular basis, resulting in reduced radiation and health risks while preserving diagnostic accuracy.
