Objectives: To evaluate and compare the diagnostic value of computer-assisted caries detector Logicon with other diagnostic methods. Materials and Methods: This study was conducted on 300 proximal surfaces corresponding to 150 posterior teeth. The diagnostic techniques employed comprised an ORIx 65 kV intraoral radiodiagnostic apparatus, Trophy RVG system in normal mode, and in combination with a caries diagnosis assisting program by Logicon. The same X-ray source was used for the entire study, followed by comparison with histological sections of the teeth used which were observed under light microscope. The positive and negative predictive values, sensitivity, specificity, and probability ratio were calculated. Results: Application of computer-assisted caries detector Logicon increased sensitivity for the cases where caries was extending into the dentin. In contrast, conventional radiography showed a higher specificity and positive predictive value, whereas the negative predictive values were the same for both techniques. Conclusion: This study has demonstrated that Logicon Caries Detector can enable dentists to find 49% more cases of caries penetrating the dentin than they were able to find without it.
