Book excerpt: A polarization sensitive optical imaging system is used to detect changes in polarization in dental tissues to aid the diagnosis of dental disease such as caries. The degree of depolarization is measured by illuminating the dental tissue with polarized light and measuring the polarization state of the backscattered light. The polarization state of this reflected light is analyzed using optical polarimetric imaging techniques. A hand-held fiber optic dental probe is used in vivo to direct the incident beam to the dental tissue and collect the reflected light. To provide depth-resolved characterization of the dental tissue, the polarization diagnostics may be incorporated into optical coherence domain reflectometry and optical coherence tomography (OCDR/OCT) systems, which enables identification of subsurface depolarization sites associated with demineralization of enamel or bone.

Available in PDF, EPUB and Kindle. Book excerpt: A method for detecting the presence of active and inactive caries in teeth and diagnosing periodontal disease uses non-ionizing radiation with techniques for reducing interference from scattered light. A beam of non-ionizing radiation is divided into sample and reference beams. The region to be examined is illuminated by the sample beam, and reflected or transmitted radiation from the sample is recombined with the reference beam to form an interference pattern on a detector. The length of the reference beam path is adjustable, allowing the operator to select the reflected or transmitted sample photons that recombine with the reference photons. Thus radiation scattered by the dental or periodontal tissue can be prevented from obscuring the interference pattern. A series of interference patterns may be generated and interpreted to locate dental caries and periodontal tissue interfaces.

Book Synopsis Optical Coherence Tomography in Dentistry by : Anderson S. L. Gomes
Download or read book Optical Coherence Tomography in Dentistry written by Anderson S. L. Gomes and published by CRC Press. This book was released on 2023-08-08 with total page 275 pages. 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.

Book Synopsis Polarization Sensitive Optical Coherence Tomography Detection Method by :
Download or read book Polarization Sensitive Optical Coherence Tomography Detection Method written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study demonstrates the potential of polarization sensitive optical coherence tomography (PS-OCT) for non-invasive in vivo detection and characterization of early, incipient caries lesions. PS-OCT generates cross-sectional images of biological tissue while measuring the effect of the tissue on the polarization state of incident light. Clear discrimination between regions of normal and demineralized enamel is first shown in PS-OCT images of bovine enamel blocks containing well-characterized artificial lesions. High-resolution, cross-sectional images of extracted human teeth are then generated that clearly discriminate between the normal and carious regions on both the smooth and occlusal surfaces. Regions of the teeth that appeared to be demineralized in the PS-OCT images were verified using histological thin sections examined under polarized light microscopy. The PS-OCT system discriminates between normal and carious regions by measuring the polarization state of the back-scattered 1310 nm light, which is affected by the state of demineralization of the enamel. Demineralization of enamel increases the scattereing coefficient, thus depolarizing the incident light. This study shows that PS-OCT has great potential for the detection, characterization, and monitoring of incipient caries lesions.
Book Synopsis Oral Diagnosis by : Petra Wilder-Smith
Download or read book Oral Diagnosis written by Petra Wilder-Smith and published by Springer Nature. This book was released on 2019-11-30 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this book is to provide the reader with an understanding of the new minimally invasive techniques that are available for the purpose of diagnostic imaging in dentistry and to explain their impact on clinical practice. The book concentrates very much on those techniques that are clinically applicable and useful to dentists NOW, although it also provides a fascinating view to the future. The chapters are divided according to the major clinical topics in dentistry. Each chapter provides considerable visual content, including flow charts, schematics, and photographs. The principles of the technologies presented are discussed in an overview format, with greater detail and focus on the ensuing clinical application techniques and the data that they can generate. The strengths and limitations of the novel modalities are highlighted. Finally, the interface between the data and their capacity for improving clinical outcomes through better diagnosis is discussed. All of the authors have been selected on the basis of their pre-eminence in the field.
Book Synopsis Detection and Assessment of Dental Caries by : Andrea Ferreira Zandona
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.

Book Synopsis Shedding the Polarized Light on Biological Tissues by : Igor Meglinski
Download or read book Shedding the Polarized Light on Biological Tissues written by Igor Meglinski and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the early-stage detection of cancer using polarized light. It discusses the diverse properties of the light (temporal and spatial coherence, polarization, fluorescence, etc.) that can be used non-invasively as an optical technique for recognizing precancerous lesions, which could become a reliable and accurate method for cancer screening. The search for the effective means for cancer screening is of particular interest to scientific and medical communities, because cancer takes its toll around the globe with no respect for age or gender. Early detection of the disease is a key factor in increasing the survival rate and patients' quality of life.
