The RVG system: clinical, ergonomic and radioprotection aspects

In view of the need to increase the application of ergonomic and radioprotection principles in dentistry, the authors explored the possibility of reducing the exposure times of conventional radiographic examinations by using more sensitive (F speed) films. They also examined the scope for simplifying, through recourse to digital systems, certain procedures used in endodontic treatment, namely the realisation, filing and management of radiographic images. The Visualix HDI, Denoptix, Trophy RVG 5 Gold, Trophy- Kodak RVG Ultimate, RVG Anthos DSX, and RVG Schick CDR digital systems were considered. A total of 138 examinations (74 using stiff sensors, 18 using Denoptix system phosphorus sensors, and 46 using conventional F speed film) were carried out. Similar projections of the examined teeth were used in all the examinations, both conventional and digital. Dental clamps were applied to the examined teeth in order to simulate digital clinical procedures. The possibility of using rigid sensors in the presence of different oral morphologies was evaluated. Conventional images and projections were compared qualitatively with digital ones. The visual definition of the apical third of 08-10-15 Kfiles, used in the digital examination of the root canal length of 17 extracted teeth, was also considered.
