Available in PDF, EPUB and Kindle. Book excerpt: Optical Coherence Tomography (OCT), a method to "see inside of things" without destroying them, has been applied to subjects ranging from materials science to medicine. This book focuses on the biomedical application of OCT in dentistry, covering topics from dental materials to clinical practice. Since the introduction of the OCT method in ophthalmology in 1991, and then dentistry in 1998, developments in OCT methods, particularly in biomedical areas, have led to its dissemination worldwide. The chapters of this book cover the basics and recent global advances of OCT in dentistry, including an overview of the method and its use in cariology, restorative dentistry, dental materials, endodontics, pediatric dentistry, orthodontics, prosthodontics, soft oral tissues and nanodentistry. This book will be of interest to both newcomers in the field as well as those already working in OCT, either in research and/or the clinic. It will be of great use in courses on optical imaging applied to biomedical areas, particularly where it can provide real-life examples of the application of OCT.

Download or read book Optical Coherence Tomography for Early Detection of Dental Diseases written by Christine Charles Sahyoun and published by . This book was released on 2016 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflammation of the gums and tooth decay are conditions that, if detected early enough, can be corrected or reversed. There is therefore a need for minimally invasive, accurate assessment of dental and periodontal tissue in order to achieve prompt diagnosis and treatment. Optical coherence tomography (OCT) is an emerging non-invasive, non-ionizing imaging modality that provides cross-sectional images of tissue, up to several millimeters in depth with micrometer level resolution. The underlying hypothesis of this thesis is that biological alterations to oral tissues result in changes in light scattering behavior which could be quantified by OCT. In vitro bovine tooth samples were demineralized in 30% H3PO4 for exposure times ranging from 0 to 5 seconds. Volume OCT scans were taken and the mean backscattered intensity as a function of depth was generated for each exposure time. Microhardness indentation measurements were also recorded. A significant negative correlation (p 0.05) was found between OCT surface peak intensity (dB) and Knoop hardness number (KHN). Ten human subjects underwent OCT imaging before and after dry brushing the gingiva to induce inflammation. Mean backscattered OCT intensity versus depth plots were generated from pre- and post-brushing images. The slope of a linear fit to the intensity vs depth plot, and the area under the curve (AUC) were determined for epithelium and the lamina propria layers and compared between baseline and post-treatment. No appreciable factor change in either the fitted slope or AUC were measured for the epithelium (p 0.05) and no appreciable factor change in the AUC was measured for the lamina propria (p> 0.05). There was a significant factor change in slope for the lamina propria region (p

Download or read book Detection and Assessment of Dental Caries written by Andrea Ferreira Zandona and published by Springer Nature. This book was released on 2019-11-06 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how to optimize clinical conditions for detection of the earliest visible signs of dental caries and how best to assess caries activity as a basis for effective management. The available evidence from the literature on detection criteria and methods is distilled and placed in a clinical context to facilitate implementation in clinical practice. Guidance is offered on removal of the dental biofilm and the potential impact of various factors on the performance of different caries detection devices. The histological changes that occur during the caries process and their effect on the clinical appearance of caries lesions are explained. In addition, several caries classification systems based on visual detection criteria and designed to allow staging are presented. Consideration is also given to currently marketed detection aids, including methods involving light fluorescence, transillumination, and radiography. In each case, a summary of the detection performance, based on available supporting evidence, is tabulated together with advice on appropriate clinical application. The reader will find the text to be clearly written and informative, with many supporting clinical images.

Download or read book The Use of Optical Coherence Tomography as a Diagnostic Tool for Dental Caries written by Rawan Waleed Al-Khuwaitem and published by . This book was released on 2019 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental caries is one of the most common human diseases, 60-90% of school children world-wide have dental cavities. Severity can vary, from early demineralisation, which preventive measures can improve, to cavitation, leading to fillings. Different diagnostic tools are available, such as clinical examination, radiographic investigation and Enhanced Visual examination/In-ternational Caries Detection and Assessment System (ICDAS). To date, there is no universal diagnostic tool that can be used to detect carious lesions at the very early stages. Optical Coherence Tomography (OCT) is a non-invasive and ionising radiation free technique that has been used in dentistry, but not to diagnose caries. // The aim of this research was to investigate the use of OCT imaging in dentistry as a routine, and adjunct clinical diagnostic tool for dental caries, by developing standardised markers for each ICDAS score, and to compare the results with conventional clinical methods i.e. radio-graphs and ICDAS. In addition, markers in the OCT scan and scattering profile intensity plots for both sound and carious affected teeth were determined, to aid diagnosis. // All specimens were collected from patients undergoing dental treatment at Eastman Dental Hospital. Extracted human primary and permanent teeth (N>180) with varying caries severity were collected under ethical approval, after obtaining informed consent according to the inclu-sion and exclusion criteria. Photographic and radiographic images of tooth samples were taken and categorised according to the ICDAS system. Samples were then imaged using OCT (VivoSight OCT Scanner) with each lesion scanned separately (N>200). The scattering inten-sity profiles were plotted. In healthy samples, OCT B-scans showed a homogenous pattern of scattering intensity throughout enamel structure indicating healthy structure while in carious teeth, a non-homogenous scattering intensity was observed indicating changes in enamel structure. // Different scattering intensity profiles for each ICDAS score were observed, and empirical markers were developed for each score. This led to establishing scattering fingerprints for each type of ICDAS lesion. A multi-assessor"s analysis, followed by a kappa analysis, was carried to evaluate the selectivity and accuracy of the makers. The results showed moderate to substantial strength of agreement in both intra-rater and inter-rater reliability. // In conclusion, OCT has been shown to be a safe, useful, reliable and non-destructive tech-nique that can investigate the internal structure by measuring the back-scattered light from enamel and dentine. OCT provides an understanding of the lesion in terms of depth and ex-tent, therefore helping in predicting the lesion"s prognosis, which is not found in conventional methods. In addition, OCT helps to differentiate between carious and sound teeth, and addi-tionally between different ICDAS scores. The definition of specific scattering markers for each type of caries lesions will enable us to bring this technique one-step closer to the clinic.

Download or read book Optical Coherence Tomography Guided Dental Drill written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A dental drill that has one or multiple single mode fibers that can be used to image in the vicinity of the drill tip. It is valuable to image below the surface being drilled to minimize damage to vital or normal tissue. Identifying the boundary between decayed and normal enamel (or dentine) would reduce the removal of viable tissue, and identifying the nerve before getting too close with the drill could prevent nerve damage. By surrounding a drill with several optical fibers that can be used by an optical coherence domain reflectometry (OCDR) to image several millimeters ahead of the ablation surface will lead to a new and improved dental treatment device.
