2. Imaging natural occlusal caries lesions with optical coherence tomography

   Explore Article SPIE Digital Library (Mar 5 2010) Dentistry

   Several studies have demonstrated that polarization-sensitive optical coherence tomography (PS-OCT) can be used to nondestructively measure the severity of demineralization in the important occlusal surfaces. The purpose of this study was to assess the potential of PS-OCT and OCT methods for the measurement of the depth of natural occlusal carious lesions. Teeth were screened for potential occlusal lesions using near infrared imaging (NIR). A PS-OCT system operating at 1310-nm was ... (Read Full Article)

3. Imaging early demineralization with PS-OCT

   Explore Article SPIE Digital Library (Mar 5 2010) Dentistry

   New methods are needed for the nondestructive measurement of tooth demineralization and remineralization to monitor the progression of incipient caries lesions (tooth decay) for effective nonsurgical intervention and to evaluate the performance of anti-caries treatments such as chemical treatments or laser irradiation. Studies have shown that optical coherence tomography (OCT) has great potential to fulfill this role since it can be used to measure the depth and severity of early ... (Read Full Article)

4. Imaging simulated secondary caries lesions with cross polarization OCT

   Explore Article SPIE Digital Library (Mar 5 2010) Dentistry

   The clinical diagnosis of secondary caries has been found to account for the replacement of the majority of intra-coronal restorations. Current methods to diagnose the presence of these lesions at early stages are considered insufficient due to their low sensitivity. Polarization-sensitive optical coherence tomography (PS-OCT) imaging studies have confirmed its effectiveness for imaging carious subsurface lesions in enamel and dentin. The objective of this study was to determine if PS-OCT ... (Read Full Article)

5. Near-IR polarization imaging of sound and carious dental enamel

   Explore Article SPIE Digital Library (Mar 4 2010) Dentistry

   A thorough understanding of how polarized near-IR light propagates through sound and carious dental hard tissues is important for the development of dental optical imaging systems. New optical imaging tools for the detection and assessment of dental caries (dental decay) such as near-IR imaging and optical coherence tomography can exploit the enhanced contrast provided by polarization sensitivity. In this investigation, an automated system was developed to collect images for the ... (Read Full Article)

7. Distinctive Findings in a Patient With Axenfeld–Rieger Syndrome Using High-Resolution AS-OCT

   Explore Article Ophthalmic Surgery, Lasers and Imaging (Nov 26 2009) Ophthalmology

   Some distinct findings of a patient with Axenfeld-Rieger syndrome from the anterior chamber angle images by high-resolution anterior segment optical coherence tomography (AS-OCT) are described. The typical anterior segment anomalies of Axenfeld-Rieger syndrome, including iris atrophy, posterior embryotoxon, peripheral bridging tissue bands, trabecular meshwork elongation, and high insertion of the iris root into the posterior trabecular meshwork, can be visualized clearly on AS-OCT images. Specifically, the high-resolution mode of the ... (Read Full Article)

8. Near-infrared image-guided laser ablation of dental decay

   Explore Article SPIE Digital Library (Oct 30 2009) Dentistry

   Image-guided laser ablation systems are now feasible for dentistry with the recent development of nondestructive high-contrast imaging modalities such as near-IR (NIR) imaging and optical coherence tomography (OCT) that are capable of discriminating between sound and demineralized dental enamel at the early stages of development. Our objective is to demonstrate that images of demineralized tooth surfaces have sufficient contrast to be used to guide a CO2 laser for the selective ... (Read Full Article)
