“…Initial in-vitro studies using ICDAS-II for detection of occlusal lesions showed lower overall performance of ICDAS-II (AUC between 0.73-0.88) (Jablonski-Momeni et al 2008) and (Rodrigues et al 2008). Later studies showed an increase of ICDAS-II performance, sensitivity, and specificity values which might be explained by the enhanced training in this system (Jablonski-Momeni et al 2017).…”

Aim: This study aimed to compare the diagnostic predictive values of a light induced fluorescence intra oral camera (VistaCam iX) versus visual assessment method (ICDAS-II) in identification of occlusal carious lesion. Methodology: Occlusal surfaces of 199 molar teeth from 43 adult patients who fulfill the eligibility criteria were examined by two observers using two diagnostic methods. The teeth were firstly assessed visually according to the criteria of the International Caries Detection and Assessment System (ICDAS-II) then by fluorescence camera. Inter observer agreement was measured for ICDAS-II using Kappa and weighted Kappa Values and for the camera using inter class correlation (ICC). Correlation between methods was calculated using Spearman's rank correlation coefficient (r s) and the Receiver Operating Characteristic (ROC curve) between the tested methods was estimated. Results: Significant positive correlation was found between the ICDAS-II and the camera measurements (r s = 0.8739, P< 0.001). The area under the ROC curve was (0.932, p< 0.001) indicating a great association between the two tested methods when selecting adequate cutoff values for the camera. There was a statistically significant agreement between the two observers for ICDAS-II values (Kappa =0.8125, weighted Kappa = 0.8558). Excellent inter examiner agreement was found between the two observers when using the FC, ICC = 0.9774 (95% CI, 0.789 to 0.889), (p<0.001). Conclusion: The camera showed high reliability and agreement with ICDAS-II for initial occlusal caries detection. Sensitivity and specificity values for the camera varied depending on the cutoff value.

“…Although not directly compared, commercial NIR‐camera‐based dental imaging systems use wavelengths below 900 nm so that inexpensive small silicon‐based cameras can be used. However, these wavelengths have 10 times higher optical scattering coefficient than 1200–1800 nm which may limit its imaging depth and diagnostic accuracy . Current 1200–1800‐nm NIR imaging requires InGaAs‐based pixel‐array cameras which are bulky and expensive .…”

Near‐infrared multispectral endoscopic imaging of deep artificial interproximal lesions in extracted teeth

et al. 2019

Background and Objective A safer alternative method to radiographic imaging is needed. We present a multispectral near‐infrared scanning fiber endoscope (nirSFE) for dental imaging which is designed to be the smallest imaging probe with near‐infrared (NIR) imaging (1200–2000 nm). Materials and Methods The prototype nirSFE is designed for wide‐field forward viewing of scanned laser illumination at 1310, 1460, or 1550 nm. Artificial lesions with varying sizes and locations were prepared on proximal surfaces of extracted human teeth to examine capability and limitation of this new dental imaging modality. Nineteen artificial interproximal lesions and several natural occlusal lesions on extracted teeth were imaged with nirSFE, OCT, and microCT. Results Our nirSFE system has a flexible shaft as well as a probe tip with diameter of 1.6 mm and a rigid length of 9 mm. The small form factor and multispectral NIR imaging capability enables multiple viewing angles and reliable detection of lesions that can extend into the dentin. Among nineteen artificial interproximal lesions, the nirSFE reflectance imaging operating at 1460‐nm and OCT operating at 1310‐nm scanned illumination exhibited high sensitivity for interproximal lesions that were closer to occlusal surface. Diagnosis from a non‐blinded trained user by looking at real‐time occlusal‐side nirSFE videos indicate true positive rate of 78.9%. There were no false positives. Conclusions This study demonstrates that nirSFE may be used for detecting occlusal lesions and interproximal lesions located less than 4 mm under the occlusal surface. Major advantages of this imaging system include multiple viewing angles due to flexibility and small form factor, as well as the ability to capture real‐time video. The multispectral nirSFE has the potential to be employed as a low‐cost dental camera for detecting dental lesions without exposure to ionizing radiation. Lasers Surg.

“…However, moisture or saliva contamination has not affected the scores. Jablonski-Momeni et al compared near-infrared imaging system (VistaCam iX Proxi) and conventional digital radiographs for the diagnosis of proximal enamel lesions and found that there was moderate agreement between the methods and found no significant difference 18. A recent systematic review on LIF with Soprolife IOC has concluded that there was no clear evidence on the detection of occlusal caries lesions and recommended future studies 19…”

Technological advancements in the field of dentistry have reformed the concept of photography as a powerful medium of expression and communication. It also offers a spectrum of perception, interpretation, and execution. One of the widespread clinical applications of computerization in dentistry today is the intraoral camera (IOC). It helps in the revelation of the hidden and overlooked defects in teeth and other parts of the cavity. Dental world constitutes of microstructures that have to be recorded in a detailed manner to perform patient education, documentation of records and treatment, illustration of lectures, publication and web connectivity of complicated cases. This review emphasizes the significant applications of IOC in dentistry and its possible impact on patient compliance for dental care.
