Introduction: Initial proximal caries is both diagnostic and therapeutic challenge. The disadvantages of the conventional methods for caries detection and the development of technologies led to the creation of contemporary optical devices for early caries detection. Aim: In vitro comparison of the diagnostic accuracy of several methods for early proximal caries detection – visual-tactile, bitewing radiography and laser fluorescence device (DIAGNOdent pen). Materials and methods: Fifty-eight proximal surfaces of extracted human permanent premolars and molars were examined by two examiners using visual inspection, bitewing radiography, DIAGNOdent with proximal contact, and DIAGNOdent directly in the lesion. Results were compared with the histological gold standard. Statistical analysis with ROC curve, sensitivity, specificity and diagnostic accuracy of each detection method was performed. Analysis was conducted in 3 diagnostic thresholds – initial, developed and advanced demineralization. Results: Sensitivity of visual inspection was 16%–33%, specificity 93.3%–100%, sensitivity of bitewing radiography 54%–67%, speci­ficity 93%–94%, sensitivity of DIAGNOdent with proximal surfaces in contact 88%–91%, specificity 79%–89%, sensitivity of DIAG­NOdent directly 89%–92.5%, specificity 81.29%–93%. The highest diagnostic accuracy, increasing with the rise of the level of demin­eralization, was shown by DIAGNOdent directly, followed by DIAGNOdent with proximal contact, bitewing radiography, and visual inspection with the lowest accuracy. Conclusion: The use of contemporary diagnostic devices significantly increases the possibility for early detection of proximal lesions. DIAGNOdent can be used as an adjunct to and increasing the diagnostic accuracy of the conventional caries detection methods.

Objective:The aim of this study was to evaluate the ability of PTR-LUM (The Canary System, CS), laser fluorescence (DIAGNOdent, DD), LED fluorescence (Spectra), and visual inspection (ICDAS II) to detect natural decay around bonded amalgam restorationsin vitro.Methods:Seventeen extracted human molars and premolars, consisting of visually healthy (n=5) and natural cavitated (n=12) teeth were selected. For the carious teeth, caries was removed leaving some decayed tissue on the floor and or wall of the preparation. For sound teeth, 3 mm. deep cavity preparations were made and teeth were restored with bonded-amalgam restorations. Thirty-six sites (13 sound sites; 23 carious sites) were selected. CS and DD scans were performed in triplicate at 2, 1.5, 0.5, and 0 mm away from the margin of the restoration (MOR). Spectra images were captured for the entire surface, and dentists blinded to the samples provided ICDAS II scoring.Results:Canary Numbers (Mean±SE) for healthy and carious sites at 2, 1.5, 0.5, and 0 mm from the MOR ranged from 12.9±0.9 to 15.4±0.9 and 56.1±4.0 to 56.3±2.0, respectively. DD peak values for healthy and carious sites ranged from 4.7±0.5 to 13.5±2.99, and 16.7±3.7 to 24.5±4.4, respectively. For CS and DD, sensitivity/specificity for sites at 2.0, 1.5, 0.5, 0 mm ranged from 0.95-1.0/0.85-1.0, and 0.45-0.74/0.54-1.0, respectively. For ICDAS II, sensitivity and specificity were 1.0 and 0.17, respectively. For Spectra, data and images were inconclusive due to signal intereference from the amalgam restoration.Conclusions:Using thisin-vitromodel, CS and DD were able to differentiate between sound and carious tissue at the MOR, but larger variation, less reliability, and poorer accuracy was observed for DD. Therefore, CS has the potential to detect secondary caries around amalgam restorations more accurately than the other investigated modalities.

The aim of the present study was to compare the diagnostic accuracy/efficacy of digital imaging fiber-optic transillumination (DIFOTI) with film and digital radiography, in detection of approximal caries lesions. One hundred and twelve approximal surfaces were scored for caries, using DIFOTI images film and digital radiographs. All three sets of images were examined twice by 8 observers, with a minimal interval of one week between examinations. Validation of histological sections served as a reference standard. Reproducibility, based on intra- and interobserver agreement, was similar for all three methods. At diagnostic threshold D1 (enamel and dentin caries), DIFOTI showed significantly higher sensitivity, but differences in specificity between methods were nonsignificant. Diagnostic accuracy in the form of area under the receiver operating characteristic curve (AUC) was significantly higher for DIFOTI. At diagnostic threshold D3 (dentin caries), the differences in sensitivity and AUC among methods were nonsignificant, but DIFOTI showed significantly lower specificity. Compared with the radiographs, DIFOTI showed closer agreement, expressed as weighted kappa values, with the reference standard. The results show that underin vitroconditions, the diagnostic accuracy of DIFOTI in detecting early approximal enamel lesions is greater than that of film and digital radiography, while the potential for detecting lesions in dentin is similar for all three methods.
