Proximal surface lesions are not very often detected by X-ray examination, suggesting the predominance of a subjective diagnosis on the part of the dentist. Since the magnitude of light scattering within the tooth decreases exponentially at longer wavelengths, evaluation of transillumination by near infra red lasers is a new alternative noninvasive technique to detect and quantify demineralization...
Summary form only given. Dental restoration interfaces can present failures, known as marginal microleakage. These failures are extremely difficult to diagnose and can develop into recurrent caries if left untreated. The most common tool used for diagnostic imaging in dentistry, X-ray, is not able to visualize micrometric structures. Evaluation of dental restoration in a non-invasive way is a very...
We demonstrate a compact silicon-on-insulator wavelength division multiplexer. The device supports 21 channels, has 1 nm channel spacing and less than -10 dB crosstalk.
An optical coherence tomography (OCT) system with 6μm spatial resolution was employed to image the sites of fracture initiation and slow crack propagation in a fiber reinforced composite. Bar specimens (2mm×3mm×25mm) of fiber reinforced composite were mechanically and thermally cycled to emulate oral conditions. The interior of the samples were analyzed prior and after the emulations. We analyzed...
