Evaluation of panoramic image quality in three images system.

Abstract

In vitro study to evaluate the diagnostic image quality of dental panoramic radiography by comparing between conventional and digital systems. Aim of the Study: The aim of this study was to compare and evaluate the image quality of panoramic radiograph. Material and Method: Study comparing the image quality of dental Panoramic between conventional and digital in three dental institutions diagnostic imaging department. Forty five panoramic image were collected and divided in to three groups consisting of conventional images obtained with STRATO 2000, CE by VILLA SISTEMI MEDICALI–ITALY (screen based film) Dimax3digital system pan/ceph, PLANMECA, Helsinki, Finland, and Kodak 8000 carestream health, France (CCD X–ray image sensor). Image quality was assessed by rating the visibility of three evaluation aspect commonly found on panoramic radiographs for each image Depending on three evaluation aspect which is include the anatomy coverage, contrast and density of the teeth and anatomical structure, high score representing better image quality and the lower score indicating poor image quality. Results: the data collected from the evaluation of digital and film based image by two examiner were analyzed by chi square and the difference was statistically significant. Conclusion: The highest quality scores were obtained with carestream health digital system whereas images from Dimax3 digital system and conventional panoramic image type by VILLA SISTEMI were ranked significantly lower.
