This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to compare the accuracy and precision of linear measurements made on conventional lateral cephalograms (LC) and simulated LC using cone-beam computed tomography (CBCT) to direct measurements on dentate skulls. The linear distances for 5 mid-sagittal and 4 bilateral measurements between anatomical landmarks on 22 skulls were measured by two observers. The skulls were imaged using a CBCT scanner at 4 scan settings: high resolution (0.2mm) and normal resolution (0.4mm) at 20-sec (306 projections) and 40-sec scans (612 projections). Three simulated LC were generated: Ray sum image reconstructions of the maximum thickness mid-sagittal multiplanar projections, a single frame basis projection, and the scout image. LCs were acquired using a storage phosphor system. Projection images were exported into a cephalometric analysis program and linear measurements determined. Analyses were repeated three times and statistically compared to measured anatomic truth using repeated measures general linear model (p [less than or equal to] 0.05). The mean absolute error was used as an index of precision. While there were statistical differences between skull and modality measurements for 6 of the nine measurements, there were no overall differences between LC and CBCT derived image measurements irrespective of method of construction. CBCT imaging provides clinically reliable 2D simulation images however, dose considerations demand that evidence-based selection criteria should be developed for CBCT in orthodontics that take into account the ALARA principle.

Periago and published by . This book was released on 2007 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to compare the accuracy and reliability of linear measurements made on 2D projections and 3D reconstructions using Dolphin 3D software (Chatsworth, CA) as compared to direct measurements made on human skulls. The linear dimensions between 6 bilateral and 8 mid-sagittal anatomical landmarks on 23 dentate dry human skulls were measured three times by multiple observers using a digital caliper to provide twenty orthodontic linear measurements. The skulls were stabilized and imaged via PSP digital cephalometry as well as CBCT. The PSP cephalograms were imported into Dolphin (Chatsworth, CA, USA) and the 3D volumetric data set was imported into Dolphin 3D (Version 2.3, Chatsworth, CA, USA).Using Dolphin 3D, planar cephalograms as well as 3D volumetric surface reconstructions were (3D CBCT) generated. The linear measurements between landmarks of each three modalities were then computed by a single observer three times. For 2D measurements, a one way ANOVA for each measurement dimension was calculated as well as a post hoc Scheffe multiple comparison test with the anatomic distance as the control group. 3D measurements were compared to anatomic truth using Student's t test (P [less than or equal to] 50.05). The intraclass correlation coefficient (ICC) and absolute linear and percentage error were determined as indices of intraobserver reliability. Our results show that for 2D mid sagittal measurements that Simulated LC images are accurate and similar to those from PSP images (except for Ba-Na), and for bilateral measurements simulated LC measurements were similar to PSP but less accurate, underestimating dimensions by between 4.7% to 17%.For 3D volumetric renderings, 2/3 rd of CBCT measurements are statistically different from actual measurements, however this possibly is not clinically relevant.

This book was released on 2008 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective. To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods. Sixteen linear dimensions between anatomical sites marked on 19 human skulls were directly measured. Skulls were imaged with CBCT at three settings: 153, 306, and 612 basis projections. The mean absolute error and modality mean of linear measurements between landmarks on 3D images were compared to the anatomic truth. Results. No difference in mean absolute error between the scan settings was found. The average skull absolute error between marked reference points were less than the distances between unmarked reference sites. Conclusion. CBCT measurements were consistent between scan sequences and for direct measurements between marked reference points. Reducing the number of projections for 3D reconstruction did not lead to reduced dimensional accuracy and potentially provides reduced patient radiation exposure.

Book excerpt: The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume is dedicated to SDG 14 “Conserve and sustainably use the oceans, seas and marine resources for sustainable development". Marine and coastal bio-resources, play an essential role in human well-being and social and economic development. This volume addresses this sustainability challenge providing the description of a range of terms, which allows a better understanding and fosters knowledge about it. Concretely, the defined targets are: Prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution Sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels Effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics Conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information Prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation 16 Increase the economic benefits to small island developing states and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing states and least developed countries Provide access for small-scale artisanal fishers to marine resources and markets Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in the United Nations Convention on the Law of the Sea, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of “The future we want” Editorial Board Ulisses M.
