“…CBCT offers a number of potential advantages over medical tomography, including easier image acquisition, higher image accuracy, reduced artifacts, lower effective radiation doses, faster scan times, and greater cost-effectiveness [16,17]. Previous research has examined the effectiveness of CBCT in measuring proximal caries depth using dedicated measurement tools [18] as well as the effectiveness of CBCT in detecting occlusal caries [19] and occlusal caries mixed with proximal caries without the use of measurement tools [20,21].…”

The study aimed to assess the accuracy and reproducibility of occlusal caries depth measurements obtained from different imaging modalities. The study comprised 21 human mandibular molar teeth with occlusal caries. Teeth were imaged using film, CCD, two different cone-beam computerized tomography (CBCT) units and a microcomputer tomography (micro-CT). Thereafter, each tooth was serially sectioned, and the section with the deepest carious lesion was scanned using a high-resolution scanner. Each image set was separately viewed by three oral radiologists. Images were viewed randomly, and each set was viewed twice. Lesion depth was measured on film images using a digital caliper, on CCD and CBCT images using built-in measurement tools, on micro-CT images using the Mimics software program, and on histological images using AxioVision Rel. 4.7. Intra-and inter-rater reliabilities were assessed according to the Bland/Altman method by calculating Intraclass Correlation Coefficients (ICCs). Mean/median values obtained with intraoral systems were lower than those obtained with 3-D and histological images for all observers and both readings. Intra-observer ICC values for all observers were highest for histology and micro-CT. In addition, intra-observer ICC values were higher for histology and CBCT than for histology and intra-oral methods. Inter-observer ICC values for first and second readings were high for all observers. No differences in repeatability were found between Accuitomo and Iluma CBCT images or between intra-oral film and CCD images. Micro-CT was found to be the best imaging method for the ex vivo measurement of occlusal caries depth. In addition, both CBCT units performed similarly and better than intra-oral modalities.

“…The review of recent research showed that some studies have reported greater diagnostic values of CBCT than the other intraoral films for detecting occlusal caries [16,21,25,29]; however, in some studies there were no significant differences [11,28] (the same as in this study). These results vary with the type of CBCT system.…”

More than 75% of dental caries in children and adolescents occurs in occlusal surfaces [1]. Studies over the past two decades have shown that a significant portion of occlusal caries could not be diagnosed in the early stages because of various reasons including dentists' carelessness and inappropriate instruments [2]. Researchers believe that the diagnosis of occlusal caries was more difficult AbstractBackground. Recent Studies have shown that a significant portion of occlusal caries could not be diagnosed in the early stages because of various reasons. Early detection of superficial caries is important for preventive dentistry. Objectives. This study aims to compare the quality of occlusal caries detection using digital phosphor storage plate (PSP) and cone beam computed tomography (CBCT). Material and Methods. For this experimental study 88 human molars were used. The clinical appearances of the occlusal surfaces of the teeth ranged from sound to discolor with no macroscopic cavitation. They were imaged using a digital system (PSP) and CBCT (NewTom 3G). Three independent observers assessed the images twice. ROC curve was used for assessment of the imaging systems accuracy for the detection of caries. A histological investigation was used as a gold standard. Methods were analyzed by ANOVA and t-test with p value of 0.05. Tests were performed with STATA software (version 11). Intra and inter observers agreement for each image set was assessed by ICC. Results. The average of observers results in caries detection with PSP images was 0.34 (P value = 0.208) and with CBCT images was equal to 0.45 (P value = 0.722). This showed that the diagnostic accuracy of CBCT and PSP was not acceptable compared with the gold standard. Although CBCT was a little higher than PSP on ROC curve, statistically there were no significant differences between both images in detecting occlusal caries. The ICC results showed acceptable agreement between observers in caries detection by CBCT and PSP, but the agreement between observers using these image modalities and the gold standard was poor. Conclusions. The accuracy of NewTom 3G CBCT for detecting occlusal caries was slightly better than PSP (not significantly), but none of them had the sufficient diagnostic accuracy for detecting incipient occlusal caries. Therefore, in these cases it is necessary to use other methods to improve detection (Dent. Med. Probl. 2016, 53, 2, 186-192).

“…Authors diverge on the superiority of CBCT images against conventional radiographic images for the detection of caries lesions, especially interproximal images. According to Haiter-Neto et al 17 and Young et al 18 , CBCT and digital radiographic images fail to detect incipient enamel caries lesions, as both methods present low sensibility values Charuakkra et al 3 and Valizadeh et al 11 evaluated the CBCT accuracy on proximal caries detection and compared its results to conventional radiographs. Although those studies had similar aims, their conclusions were different.…”

ObjectiveThe objective of study was to evaluate the diagnostic quality of CBCT images for caries lesions detection using different exposure parameters. MethodsSixty extracted human teeth were selected and scanned using Kodak 9000 3D CBCT system, with the following exposure parameters combinations: 74 kV, 10mA; 74 kV, 12mA; 74 kV, 8 mA; 70 kV, 10 mA; 70kV, 12 mA; 70 kV e 8 mA; 70 kV, 6.3 mA. Two observers evaluated the images for caries presence using CS 3D Imaging Software. Each observer scored the proximal surfaces of each tooth on a 5-point scale. The scores were compared to histological sections used as gold standard. Accuracy for caries lesion detection was assessed for each exposure parameter combination and evaluated by means of ROC curve analysis. ResultsThe mean values for the areas under the ROC curves for each exposure parameter combination varied from 0.35 to 0.60. There was no statistical significant difference among protocols 1,2,4, 6 and 7. However, protocols 3 and 5 differed from all protocols. ConclusionAlthough the highest dose protocol was the most efficient for proximal caries detection, the lowest dose protocol should be chosen based on the ALADA principle.
