“…OCT has clinical credibility of being a promising applications in a clinical detection and monitoring of early enamel caries (Jones et al, 2006; Kitasako et al, 2019). Moreover, OCT is expected to be a valuable tool for dentists and patients, providing non‐invasive and real time diagnostic information related to dental lesions and gaps in the context of operative and preventive treatments (Macey et al, 2021; Natsume et al, 2011; Sampaio et al, 2016). FD‐OCT could detect small enamel remineralization changes and there was a significant correlation between optical and mechanical findings (de Cara et al, 2012, 2014).…”

“…Therefore, OCT is a no destruct promising technique to diagnose the first stage of caries disease allowing their clinical management and progression through the longitudinal evaluation of enamel demineralization (Kitasako et al, 2019; Macey et al, 2021). The technique is based in optical laws, where porous created in demineralized tissue increase the light scattering, causing changes on the optical properties of enamel during the decay process and allowing quantitative measurement of optical properties providing a repeatable means of tissue characterization (Jones & Fried, 2006; Kang, Darling, & Fried, 2011).…”

The treatment of high-risk patients still is a challenge. The understanding and development non-invasive, non-destructive, and non-ionizing techniques, can help to guide the treatment and the diagnosis of primary and recurrent caries. The present study evaluated the behavior of enamel/restoration interface after a cariogenic challenge by Fourier domain optical coherence tomography (FD-OCT), scanning electron microscopy (SEM) examination, and the fluoride release of the different restorative materials. Cavities (1.5 Â 0.5 mm) were performed in enamel surface and divided into groups (n = 8): glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and resin composite (RC). The samples were submitted to pH-cycling, and the solutions analyzed for cumulative fluoride by ion-analyzer. The morphology was analyzed by SEM through replicas. The optical attenuation coefficient (OAC) was calculated through exponential decay from the images generated by FD-OCT. Data were analyzed considering α = 0.05. OAC values increased for all groups after pHcycling indicating demineralization (p < .05). Considering the remineralizing solution, RMGIC presented higher fluoride release rate, followed by GIC, while RC did not release any fluoride. Yet for the demineralizing solution, RMGIC and GIC released similar fluoride rates, overcoming RC (p < .05). Micrographs revealed no changes on the restorations margins, although enamel detachment was observed for RC and GIC after pH-cycling.

Introduction. Missed canal is one of the common reasons for nonsurgical endodontic retreatments. The missed canals were frequently associated with periapical pathology. The aim of this systematic review was to find the diagnostic accuracy of CBCT for detection of the second canal of the root canal system of permanent teeth. Materials and Methods. The articles were selected from seven electronic databases according to selection criteria. All eligible studies were judged by the reviewers. The selected studies were checked with the QUADAS-2 tool for risk of bias and applicability concerns. Finally, 12 studies were selected for qualitative and quantitative analyses. The summary estimates of sensitivities and specificities and SROC curves were calculated and drawn by RevMan 5.3 and MetaDTA software. Results. Summary estimates of CBCT for detection of second canal anatomy in permanent teeth were 94% sensitivity and 93.1% specificity. 96.6% sensitivity of MB2 was followed by 88.8% sensitivity of maxillary and mandibular premolars and 81% that of mandibular molars. The specificity of 97.6% for premolars was trialed by 85% specificity of mandibular molars and MB2. For permanent mandibular canines, 67% sensitivity and 100% specificity were estimated. CBCT showed more agreement with detecting the second canal with micro-CT, estimating 100% sensitivity and 95.6% specificity. The highest prevalence of the second canal comprised the highest sensitivity of 99.1% and lowest specificity of 77.5%. After the exclusion of case-control studies, a 3% drop of sensitivity from the summary estimate was observed. Multiple spectrum of the second canal had 8.6% higher sensitivity and 4.4% lower specificity than single spectrum. Conclusion. CBCT is informative for detecting the second canal. Clinicians should keep in mind that the accuracy can vary in different types of teeth, with the prevalence of second canal across different populations, and with the spectrum of second canal anatomy in spite of the reviewers having postulated overestimation of the findings.

“…As Macey et al reported, high-quality studies for DC could still be useful becausetheir true effect on the dental examination does not currently seem to have been explored. 26 To assess the performance of NIRLT in clinical setting, this prospective in vivo study aimed to investigate the validity of DC, ICDAS and BWR for detecting proximal caries on permanent teeth using histology as the gold standard. The hypothesis of the study was that DC performed better than BWR and ICDAS for detecting proximal caries.…”

Purpose The aim of this study was to evaluate the performance of DIAGNOcam (DC) in diagnosing proximal caries and to compare its effectiveness with the International Caries Detection and Assessment System (ICDAS) and bitewing radiography (BWR). Methods 118 premolars extracted for orthodontic reasons were included and examined using three detection methods and validated by histological sections as the gold standard. The sensitivity, specificity and areas under the ROC curve (Az value) at the outer half enamel (D1), inner half enamel (D2) and dentine (D3) thresholds were compared between different methods. Results At all categories, the specificity of DC was almost as high as ICDAS and BWR. DC showed a significantly higher sensitivity (0.68) than both visual (0.33) and radiographic examination (0.47) at the D1 threshold. DC presented the highest Az value (area under the ROC curve) at the D1 and D2 threshold (0.81, 0.86), while BWR showed the greatest Az values at D3 (0.94). Furthermore, DC had the highest association strength with the gold standard (Spearman’s ρ = 0.80). Conclusions It can be concluded that DC could detect proximal caries effectively and showed comparable or even better performance than ICDAS and BWR.
