“…These results are consistent with those that have been reported in the literature. 15,25,27 Hintze and Wenzel, 15 using the criteria of ''definitely'' and ''probably present'' to define caries as present, found that only 18% of carious lesions were detected by radiography. In the present study, the observers reported the caries depth of each approximal surface and there were no scores of uncertainty.…”

“…This supports the conclusion of previous studies that there are no statistically significant differences between conventional film and digital systems for diagnosis of approximal caries. [18][19][20][21][22][23][24]26,27 A previous study by Hintze et al 10 indicated that the reduction in exposure with the digital systems from 25% to 10% of the exposure time needed for E-speed film resulted in statistically significant differences among the phosphor plate systems; Digora (white plate) was as accurate as conventional E-speed film and was more accurate than DenOptix and Digora (blue plate). These authors suggested that these differences were a result of the reduction in the thickness of the phosphor layer in the blue plates compared with those of the white plates.…”

Objectives: The aims of this study were (1) to compare the accuracy of the detection of approximal enamel caries lesions using three intraoral storage phosphor plate digital systems and one conventional film-based radiographic system; and (2) to determine whether there is a correlation between the histological and radiographic measurements of enamel caries. Methods: 160 approximal surfaces were radiographed under standardized conditions using three storage phosphor stimulable systems (DenOptix and Digora FMX with white and blue plates), and one film system (Insight film). 17 observers scored the images for the presence and depth of caries using a 4-point scale. The presence of caries was validated histologically (gold standard). Two-way analysis of variance was used to test the differences in sensitivity, specificity and overall accuracy (TP + TN). The data from the radiographic and histological measurements were statistically analysed by Spearman's rank correlation coefficient. Results: Two-way analysis of variance and the post hoc t-test demonstrated that Digora (white plate) had higher specificity and overall accuracy values than DenOptix (P 5 0.021); there was no statistically significant difference among the other imaging modalities (P . 0.05). There was no significant correlation between the histological depth measurements and the radiographic measurements from Digora (blue plate) (P 5 0.43), Digora (white plate) (P 5 0.15), DenOptix (P 5 0.17) and Insight film (P 5 0.06). Conclusions:The results suggest that (1) the performance of the three storage phosphor image plate systems was similar to that of the Insight film for detection of approximal enamel caries, and (2) the increase in histological depth of enamel caries was not significantly correlated with radiographic measurements.

“…Moreover, it can extend through the dentin without visible macroscopic impression on the enamel. Therefore, visual inspection is not always sufficient, and radiography is the most important appliance aside from clinical examination for caries detection (3). An ideal radiographic technique should be able to recognize the presence or absence of caries, define its quantitative size and depth, and display its activity rate.…”

Background: Different enhancements have been used to improve the diagnostic accuracy of radiographic images in digital systems. However, the diagnostic accuracy of the effects of these enhancement options on dental caries has not been determined. Objectives: This study evaluated the effects of software enhancements of zooming, colorization, and contrast conversion on the accuracy of proximal caries detection. Materials and Methods:In this diagnostic in vitro trial study, 42 non-cavitated and restoration-free extracted permanent molars and premolars were selected and mounted onto 14 blocks in contact with each other. Radiographic images were obtained from the teeth in similar standardized condition using the paralleling technique. The images were shown without any enhancement or with using the options of zooming, colorization, and contrast conversion. Depth of proximal caries was determined by a radiologist using four-scaled criteria. The diagnostic accuracy of digital images that had undergone different enhancements was calculated by the chi-square test. Results: The diagnostic odds of the original digital images were lower than 20 (5.7). By using the enhancement options of zooming, colorization, and contrast conversion, the diagnostic odds of the enamel proximal caries had a score of less than 20. The score was higher than 20 for proximal caries located in the outer and inner half of the dentin. Conclusions: The enhancement options of zooming, colorization, and contrast conversion did not significantly influence the diagnostic accuracy of digital images in enamel caries, but they enhanced caries diagnosis/progression in the outer and inner half of the dentin.

Comparative performance of digital and conventional images for detecting proximal surface caries.

Abstract: Dentists using a direct digital CCD system performed as well in interpreting proximal surface caries as with E-speed film. This work suggests that for this task these two competing systems are diagnostically comparable.
