| Abstrakt: | Objective: To evaluate and compare the diagnostic efficiency of a digital radiographic system (RadioVisioGraphy -RVG-) in combination with a diagnostic assisting program (Logicon) with RVG in basic mode, magnification and conventional radiography (Kodak). Study Design: A study was made of 384 proximal surfaces corresponding to 192 posterior teeth. The diagnostic techniques employed comprised Kodak DF-58 Ultraspeed X-rays and a Trophy RVG system used in normal mode, magnification, combination with a caries diagnosis assisting program by Logicon; Kodak DF-58 Ultraspeed radiographs were used. The same X-ray source was used in all cases. The images obtained were compared to histological sections of the teeth used. These were brewed by abrasion and observed using a light microscope. A single operator made all observations. Sensitivity, specificity, the positive and negative predictive values, and the probability ratio were calculated. Results: Application of the Logicon program increased sensitivity, specially in lesions with caries extending into the dentin. In contrast, conventional radiography yielded a higher specificity and positive predictive value. The negative predictive values were similar for both techniques. Conclusions: The RVG digital radiography and the Logicon assistance program was effective in diagnosing caries. |
