RESUMO

The aim of this study was to evaluate the efficacy of the digital systems Digora®, with white and blue phosphor plates, and DenOptix®, as well as of the radiographic film Insight®, for detection of incipient proximal caries in enamel, comparing the results achieved in the radiographic evaluation with histological measurement of the extension of these lesions. Thereafter, it was observed whether the increase in the extension of the carious lesion would increase their radiographic detection. Interproximal images were achieved from 20 phantoms, composed of human teeth, which were evaluated by 17 dental professionals as to the presence and extension of carious lesions by assigning scores. Then, the teeth were sectioned and microscopically analyzed for achievement of the gold standard. The surfaces presenting enamel caries, 64 (42.1%), were evaluated as to their extension in the enamel layer. The Friedman test was used (p<0.05) to check if there was a statistically significant difference between the mode of the radiographic evaluations of each type of image and between them and the gold standard. The nonparametric test for multiple comparisons was applied (p<0.05) to reveal which methods analyzed presented a statistically significant difference. The results did not demonstrated statistically significant differences between the digital systems and the radiographic film for diagnosis of proximal caries in enamel; however, all types of image were different from the gold standard. Comparison between the radiographic evaluations and the extension of the carious lesion in relation to the enamel layer revealed that the increase in extension of the carious lesion did not increase the radiographic detection
