“…The accuracy of older and newer versions of a CMOS system (Schick CDR/Schick CDR Wireless, Schick Technologies, Long Island City, NY) and a PSP system (Digora FMX/Digora Optime, Soredex) were compared in the detection of proximal carious lesions. 37 The new systems (Digora Optime and Schick CDR Wireless) were found to have significantly higher sensitivities than their predecessors. 37 No significant differences in specificity were found among the Digora FMX, Schick CDR and Schick CDR Wireless systems, all of which had a significantly higher specificity than the Digora Optime (P , 0.02).…”

Objective: The purpose of this study was to assess the in vitro diagnostic ability of visual inspection, film, charge-coupled device (CCD) sensor, photostimulable phosphor (PSP) sensor and cone beam CT in the detection of proximal caries in posterior teeth compared with the histological gold standard. Methods: Visual inspection, film, CCD, PSP and cone beam CT images were used to detect proximal caries in the mesial and distal surfaces of 138 teeth (276 surfaces). Visual inspection and evaluation of all intraoral digital and conventional radiographs and cone beam CT images were performed twice by three oral radiologists. Weighted kappa coefficients were calculated to assess intra-and interobserver agreement for each image set, and scores were compared with the histological gold standard using receiver operating characteristic (ROC) analysis to evaluate diagnostic ability. Results: Intraobserver kappa coefficients calculated for each observer for each method of detecting caries ranged from 0.739 to 0.928. Strong interobserver agreement ranging from 0.631 to 0.811 was found for all detection methods. The highest Az values for all three observers were obtained with the cone beam CT images; however, differences between detection methods were not statistically significant (P . 0.05). Conclusion: Visual inspection, film, CCD, PSP plates and cone beam CT performed similarly in the detection of proximal caries.

“…But Haiter-Neto et al [15] reached a different result. They concluded that NewTom 3G CBCT (with lower spatial resolution than the Accuitomo system) had a lower diagnostic accuracy for detection of caries.…”

“…These results vary with the type of CBCT system. The NewTom 3G system had the worst scores for the detection of dentin caries and Accuitomo system had higher sensitivity [15]. The detector used in NewTom 3G system is IIT/CCD (image intensifier tube/charge couple device) that has more pixel noise and image artifacts in comparison with flat panel detector systems [11].…”

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).
