“…Other authors had reported higher values of sensitivity but similar specificity values when BW radiographs were evaluated for occlusal caries detection [26, 27]. Looking at the correlation coefficients found in our study (Table 2) it can be observed that BW had the weakest correlation compared to all other methods and to the gold standard, respectively.…”

Aim. To use visual inspection (ICDAS-II), laser fluorescence (LF), fluorescence based camera (FC) and radiographic examination (BW) for detection of caries and for treatment decision. Methods. The occlusal sites of 84 extracted permanent teeth were examined using all methods and treatment decisions (preventive or operative care) were recorded based on each method independently. For validation of the findings, fissures were opened with rotating instruments and clinical depth was determined as gold standard. Correlations (r s), sensitivity, specificity and AUC were calculated. McNemar test was used to show whether different methods led to significant changes in treatment decisions. Results. Highest correlation was found between ICDAS-II and FC (r s 0.84), ICDAS-II and gold standard (0.82) and FC and gold standard (0.81). ICDAS-II provided the highest performance (AUC 1.0), followed by FC (0.95) and LF (0.88). The greatest difference was found for treatment planning of dentine lesions, where the use of FC (cut-offs according to the literature) had the greatest agreement between operative treatment and dentine lesions, followed by use of ICDAS-II. Conclusion. ICDAS-II may have high potential for detection and treatment planning, and other devices, especially the fluorescence camera, can add substantial information to the visual examination, enabling examiners plan treatment more accurately.

“…Previous studies showed that digital radiographs had similar diagnostic accuracy to that of conventional radiographs in the detection of caries [9,13,14]. In addition, the interobserver agreement was similar between conventional and digital radiographs [13]. In the present study, although the same X-ray source was used to obtain the conventional and digital radiographs, the exposure time for the digital radiographs was less than the exposure time for the conventional radiographs.…”

“…The three modalities had almost the same values for the areas under the ROC curves.

“…Recently, CBCT has also been used in vitro for the detection of caries [12]. The results of these studies have varied because of differences in the type and number of teeth included, the stage of the caries, the type of machine used, and the experience of the observers [13,14].…”

Imaging of occlusal dentine caries: a comparison among conventional radiographs, digital radiographs, and cone-beam computed tomography images

2014

Objectives To compare conventional radiographs, digital radiographs, equalized images of digital radiographs, and cone-beam computed tomography (CBCT) images for in vitro imaging of occluso-dentinal caries. Methods A total of 160 extracted human posterior teeth were evaluated in the study. All teeth were free of restorations and proximal caries. The clinical appearances of the occlusal surfaces of the teeth ranged from sound to discolored, with no macroscopic cavitation. Conventional intraoral radiographs, digital intraoral radiographs, and CBCT images of the teeth were taken. The images were evaluated independently by three observers for the presence of occluso-dentinal caries. The teeth were then sectioned and computerized images were obtained for the histological sections using a digital camera linked to a stereomicroscope at 109 magnification. The histological images were assessed for the presence or absence of dentinal caries. The sensitivity, specificity, accuracy, and area under the receiver-operating characteristic curve (Az value) were calculated for each diagnostic method.Results Sensitivity was greatest for CBCT images (mean = 0.63) and lowest for digital radiographs (mean = 0.38). Specificity was greatest for digital radiographs (mean = 0.76) and lowest for CBCT images (mean = 0.64). The mean Az values ranged from 0.56 to 0.60 (P [ 0.05). The interobserver and intraobserver agreements were greatest for CBCT images (mean kappa = 0.66 and 0.73, respectively). Conclusions There were no differences in the accuracy of detection of non-cavitated occluso-dentinal caries among the diagnostic modalities used. Cone-beam computed tomography images were more sensitive, while digital radiographs were more specific.

The aim of this in vitro study was to assess the influence of varying examiner's clinical experience on the reproducibility and accuracy of radiographic examination for occlusal caries detection. Standardized bitewing radiographs were obtained from 166 permanent molars. Radiographic examination was performed by final-year dental students from two universities (A, n = 5; B, n = 5) and by dentists with 5 to 7 years of experience who work in two different countries (C, n = 5; D, n = 5). All examinations were repeated after 1-week interval. The teeth were histologically prepared and assessed for caries extension. For intraexaminer reproducibility, the unweighted kappa values were: A (0.11-0.40), B (0.12-0.33), C (0.47-0.58), and D (0.42-0.71). Interexaminer reproducibility statistics were computed based on means ± SD of unweighted kappa values: A (0.07 ± 0.05), B (0.12 ± 0.09), C (0.24 ± 0.08), and D (0.33 ± 0.10). Sensitivity, specificity, and accuracy were calculated at D(1) and D(3) thresholds and compared by performing McNemar test (p = 0.05). D(1) sensitivity ranged between 0.29 and 0.75 and specificity between 0.24 and 0.85. D(3) specificity was moderate to high (between 0.62 and 0.95) for all groups, with statistically significant difference between the dentists groups (C and D). Sensitivity was low to moderate (between 0.21 and 0.57) with statistically significant difference for groups B and D. Accuracy was similar for all groups (0.55). Spearman's correlations were: A (0.12), B (0.24), C (0.30), and D (0.38). In conclusion, the reproducibility of radiographic examination was influenced by the examiner's clinical experience, training, and dental education as well as the accuracy in detecting occlusal caries.
