Aim: The objective of this study was to evaluate a new laser fluorescence device, DIAGNOdent for occlusal caries detection and to compare the diagnostic accuracy of DIAGNOdent with conventional bitewing radiography. And to determine the sensitivity and specificity of DIAGNOdent. Methods: 60 teeth were selected having pit and fissure carious lesions by 2 examiners. After visual and tactile examination of each lesion, DIAGNOdent readings were recorded and bitewing radiographs were taken. Caries removal was done and volume of the cavity was calculated by packing the cavity with composite of specific density. Results: Correlation between DIAGNOdent and visual tactile is 0.398 (P < 0.05); correlation between DIAGNOdent and radiographic method is 0.578 (P < 0.001). Sensitivity is 0.68 % and specificity is 0.37 %. Conclusion: DIAGNOdent is more accurate than visual- tactile and radiographic methods of caries detection. It is a more sensitive system of occlusal caries detection.
