“…Their results showed that CBCT images presented a slightly higher efficiency on caries detection with Azs of 0.528 for Promax 3D and 0.525 for Kodak 9000 3D, but there was no statistical difference from the other studied modalities. In this study, the protocol 4, the same used on Zhang et al 19 , showed one of the best results for proximal caries detection.…”

“…The results showed a significant improvement in the detection of proximal caries by CBCT images. However, other studies compared digital intraoral radiographs and CBCT images and concluded that the use of CBCT did not increase the accuracy of proximal caries detection [19][20][21] .…”

“…Zhang et al 19 evaluated two CBCT systems (Promax 3D eKodak90003D), a PSP system and radiographic film on proximal caries detection. Kodak 9000 3D was operated using 70kV and 10mA, what corresponded to the protocol 4 used in this study.…”

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.

“…Intra oral radiography provides us two-dimensional information that is not certain. The accuracy of caries detection with digital and conventional images is similar [25,26]. Because CBCT is a relatively new imaging modality, its diagnostic potential for caries detection is unclear.…”

“…Recent studies about proximal carries detection [13][14][15][16][17][18][19][20][21][22] and occlusal carries detection by CBCT [16,[21][22][23][24][25] are controversial. Most of the articles concluded that CBCT is not better than intraoral films in carries detection.…”

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).

Physical and optical studies of Gd₂O₂S:Eu³⁺ nanophosphors by microwave irradiation and γ‐irradiation methods

Gd 2 O 2 S:Eu 3+ nanophosphors have been successfully synthesized using microwave irradiation and γ-irradiation methods with polyvinyl pyrrolidone as a stabilizer. The physical and luminescence spectra were compared. The morphologies of both Gd 2 O 2 S:Eu 3+ nanophosphors were in the hexagonal phase and mainly consisted of spherical nanostructures with diameters of~90 nm and~50 nm for both microwave irradiation and γ-irradiation methods. Upon 325 nm of ultraviolet (UV) light excitation, strong red emissions (626 nm) were observed for both methods; these emissions corresponded to the 5 D 0 → 7 F 2 transition of Eu 3+ ions. However, Gd 2 O 2 S:Eu 3+ nanophosphors following microwave treatment showed better luminescence intensity than Gd 2 O 2 S:Eu 3+ nanophosphors treated with γ-irradiation. This difference was attributed to the crystallinity phase and surface quenching effects of Gd 2 O 2 S: Eu 3+ nanophosphors. The reaction mechanisms of Gd 2 O 2 S:Eu 3+ nanophosphors in both methods are discussed in detail.
