Radiography plays an important role in detection of interproximal caries. The aim of study is to compare diagnostic ability of photo stimulable phosphor (PSP) with direct measurement using stereomicroscope in detecting proximal caries. Hundred proximal surfaces of 50 extracted human posterior teeth were radiographed with dental X-ray unit. The image receptors used was storage phosphor plate Vista scan (size 2), (time of exposure 0.4 s). Radiographs were interpreted and caries lesions were classified on a 4-point scale suggested by Abesi <em>et al.</em> The teeth were sectioned with diamond disc and were examined under a stereomicroscope with 20x magnification. Diagnostic accuracy of digital image is similar to that observed with stereomicroscope. The PSP plate digital X ray system can effectively be employed for detecting proximal caries as compared to direct observation by stereomicroscope. Further study with more number of observer/evaluator and large sample size is recommended.

Abstract Optical coherence tomography (OCT) can create cross-sectional images of tooth without X-ray exposure. This study aimed to investigate the diagnostic accuracy of 3D imaging of OCT for proximal caries in posterior teeth. Thirty-six human molar teeth with 51 proximal surfaces visibly 6 intact, 16 slightly demineralized, and 29 distinct carious changes were mounted to take digital radiographs and 3D OCT images. The sensitivity, specificity and area under the receiver operating characteristic curve (AUC) for the diagnosis of enamel caries and dentin caries were calculated to quantify the diagnostic ability of 3D OCT in comparison with digital radiography. Diagnostic accuracy was evaluated by the agreement with histology using weighted Kappa. OCT showed significantly higher sensitivity, AUC and Kappa values than radiography. OCT can be a safer option for the diagnosis of proximal caries in posterior teeth that can be applied to the patients without X-ray exposure.

<p><strong>Background:</strong> Dental caries is one of the most commonly encountered conditions in clinical dentistry and these lesions remain undetected when confined to the vicinity of inter-proximal surfaces. Radiography plays a key role in the detection of inter-proximal caries especially in tight contacts.</p><p><strong>Objectives:</strong> The purpose of this study was to compare the diagnostic accuracy of E-speed film, complementary metal oxide semiconductors (CMOS) and storage phosphor systems (PSP) in the detection of proximal caries of the posterior teeth.</p><p><strong>Methods:</strong> Conventional films, CMOS and PSP images were used in detecting proximal caries on mesial and distal surfaces of 63 teeth (126 surfaces). Interpretation of all digital and conventional radiographs were performed and reanalyzed by four observers. The collected data was subjected to statistical analysis using chi square test, weighed kappa statistics and spearman rank correlation coefficient.</p><p><strong>Results:</strong> The PSP images showed more accurate results in identifying normal tooth, enamel caries, dentinal caries and deep dental caries and kappa statistics had represented almost perfect reading of 0.8 – 0.9 for PSP images whereas CMOS images showed substantial reading of 0.6 – 0.7, and for IOPA images it showed moderate reading of 0.5 – 0.6, which stated that the higher inter-observer agreement was obtained for PSP images when compared with images taken by IOPA and CMOS. The intra-observer reliability by kappa statistics had shown highly significant value (0.82) in the present study.</p><p><strong>Conclusion:</strong> Conventional films, CMOS and PSP images had shown almost appropriate results in the detection of proximal caries but PSP receptors were better in disclosing the details more accurately in terms of delineating the actual extent of the lesion pertaining to their high resolution capacity and further their flexibility made them easier during handling the radiograph, when compared with that of rigid CMOS receptors.</p>

AbstractAccurate detection and diagnosis of carious lesions is the prerequisite for application of the most effective caries management approach. However, the accuracy of proximal caries detection using visual-tactile assessment is limited. Additional diagnostic measures should therefore be performed to increase the validity of the diagnosis. Amongst various caries detection aids available, bitewing radiographs remain the gold standard for detection of proximal caries lesions. Here we describe a method for caries diagnosis using standardized bitewing holders. With this method the bitewing holders can be placed more precisely and reproducibly in the oral cavity. This approach increases accuracy of bitewing radiographs, which, due to the reproducible placement of the x-ray film, allows for monitoring of carious lesions long term.
