This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its advent in 1931, analysis of lateral cephalometric radiographs has been an important aspect of orthodontic diagnosis and treatment planning. This type of orthodontic analysis provides a quantitative evaluation of the positions of various anatomical structures of the face, including skeletal, dental, and soft tissue features. Cephalometric analysis, however, is a time-consuming process and is not always performed in clinical practice. Cephalometric analysis from Cone-Beam Computed Tomography (CBCT) imaging is particularly cumbersome, requiring both reconstruction of a two-dimensional lateral cephalogram as well as subsequent computer-assisted tracing analysis using a program such as Dolphin. As the use of CBCT continues to become more prominent in orthodontics, methodologies to expedite cephalometric analysis may be valuable in facilitating their use by clinicians. Several different commercially available (e.g. CephX) and proprietary products have been created to analyze cephalometric radiographs using automated artificial intelligence (AI), but the accuracy of these products remains incompletely established. Our study examined the accuracy and workflow impacts of CephX's ABO analysis directly from CBCT compared to manual reconstruction and tracing by human examiners on 40 CBCT volumes. We hypothesized that automatically generated cephalometric analyses from CBCT volumes would differ significantly from those generated by human examiners, and that workflow time would be statistically significantly decreased in the automated analysis. In contrast, overall workflow time was found to be significantly greater for the CephX software than for the human examiners. Furthermore, our study showed that seven of the eleven measurements in the ABO analysis differed statistically significantly from the human examiners: SNB, ANB, SN-MP, L1-NB, L1-MP, LL to E-Plane, and UL to E-Plane. Nine of the eleven measurements showed average measurement error within clinically acceptable limits, while two showed greater average error than is clinically acceptable - U1-SN and L1-MP were the least accurate measurement in our study. Bland-Altman plots were constructed showing that FMA may show a slight tendency towards greater accuracy at high values, while LL to E-Plane may display a slight tendency to underestimate more frequently at low values and overestimate more frequently at high values. Only one measurement (ANB) showed limits of agreement within the maximum allowed difference; ten out of the eleven variables exceeded the maximum allowed difference. Overall, CephX may offer clinically acceptable performance for most variables in the ABO analysis, but needs further improvement overall, particularly with the inclination of the upper and lower incisors (U1-SN and L1-MP).

Available in PDF, EPUB and Kindle. Book excerpt: Cephalometry is an imaging technique used in orthodontics to measure the size and spatial relationships of the head, jaws and teeth, making use of landmarks or points on the skull. It is used for diagnosis, treatment planning and evaluating dentofacial changes during treatment. This book focuses on understanding the different cephalometric landmarks/points. Beginning with an introduction to the technique and classification of the landmarks, the following chapters explain each point in detail, by section of the head – cranial bones, facial bones and dentition, soft tissue, cervical bones and pharynx. The final sections discuss the different types of imaging used to trace cephalometric landmarks and their applications. Key points Presents technique of cephalometry to diagnose, and plan and evaluate treatment in orthodontics Describes every landmark by section of the head, including abbreviation, definition and applications Compares alternative radiological imaging techniques Includes more than 350 colour images and illustrations

This book was released on 2012-12-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: If DNA cannot be isolated, don't give up the identification! The author has used for the same purpose methods ranging from physical anthropology to forensic medicine and especially a recent method of comparison of epigenetic traits, which proved to be very useful for the identification of family related skulls in connection with historical and other data. The kinship of 18 identified skulls (buried together in a family vault) is established by comparison of X-ray images of paranasal cavities (frontal and maxillary sinuses, orbital and nasal cavities), the shape and size of which are strongly genetically determined. The comparison also extends to numerous other epigenetic trait similarities on the skulls. It is recommended for: scientists working on human identification and studying heredity, forensic scientists, physical anthropologists, radiologists, stomatologists, paleopathologists, geneticists, historians and many others.

This book was released on 2013 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: AIM: To evaluate the accuracy of current semi-automatic and fully automatic 2D lateral cephalometric analysis programs. MATERIALS AND METHODS: 60 lateral cephalometric radiographs were randomly selected and grouped based their skeletal malocclusions to form 3 equal groups of 20 Class I, 20 Class II and 20 Class III. These radiographs were then analyzed via traditional hand-based analysis. The values obtained from this method of analysis were compared to 4 subsequent methods of analysis. These consisted of semi-automatic analysis using Dolphin Imaging software, semi-automatic analysis using Kodak Orthodontic Imaging software, fully automatic analysis using Kodak Orthodontic Imaging software and fully automatic analysis combined with limited landmark changes using Kodak Orthodontic Imaging software. RESULTS: ICC tests were completed to compare the gold standard hand-based analysis to the 4 subsequent methods. The values obtained from semi-automatic Dolphin and Kodak Orthodontic Imaging software were found to be comparable to hand-based analysis. Whereas, the values obtained from the fully automatic mode of Kodak Orthodontic Imaging software were not found to be comparable to hand-based analysis. CONCLUSIONS: Digital cephalometric programs can be used as an accurate method when performing lateral cephalometric analyses. The fully automatic mode of these programs should only be used as a support to diagnosis and not as a diagnostic tool.

This book was released on 2012-07 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cephalometric radiography is an important tool in the diagnosis and treatment planning. Manual tracing is time consuming and is subject to random and systematic error, which include identification and technical measurement errors and acquistion. The use of computerized software program offers several advantages, such as instant cehalometric analyses and image acquisition, facilitated image enhancement and archiving, and facilitated image sharing. This study was conducted to compare the Cephalometric measurements using a Compterized Software Program with Manual Tracings.19 angular and 11 linear measurements were analyzed on each radiograph. Results showed significant differences between the two methods for 5 (4 angular and 1 linear) out of 30 measurements. From the results it was concluded that both angular and linear measurements were accurate and reliable. Except, few measurements showing highly significant differences, the validity of the measurements with the software and with the conventional method are highly correlated.
