“…Various aspects of cone beam computed tomography (CBCT) image acquisition, interpretation and application to specific disciplines have been described in a recently published special issue of the Australian Dental Journal . In craniofacial clinical practice, CBCT has been indicated for assessment of various types of acquired and congenital craniofacial malformations, such as cleft palate, facial trauma, root fractures, inflammatory bony changes and benign and malignant lesions .…”

Following the invention of the first computed tomography (CT) scanner in the early 1970s, many innovations in threedimensional (3D) diagnostic imaging technology have occurred, leading to a wide range of applications in craniofacial clinical practice and research. Three-dimensional image analysis provides superior and more detailed information compared with conventional plain two-dimensional (2D) radiography, with the added benefit of 3D printing for preoperative treatment planning and regenerative therapy. Current state-of-the-art multidetector CT (MDCT), also known as medical CT, has an important role in the diagnosis and management of craniofacial injuries and pathology. Three-dimensional cone beam CT (CBCT), pioneered in the 1990s, is gaining increasing popularity in dental and craniofacial clinical practice because of its faster image acquisition at a lower radiation dose, but sound guidelines are needed to ensure its optimal clinical use. Recent innovations in micro-computed tomography (micro-CT) have revolutionized craniofacial biology research by enabling higher resolution scanning of teeth beyond the capabilities of MDCT and CBCT, presenting new prospects for translational clinical research. Even after four decades of refinement, CT technology continues to advance and broaden the horizons of craniofacial clinical practice and phenomics research.Keywords: Multidetector CT, cone beam CT, micro-CT, dentistry, teeth.Abbreviations and acronyms: 2D = two-dimensional; 3D = three-dimensional; CBCT = cone beam computed tomography; CLP = cleft lip and palate; CT = computed tomography; DEJ = dentino-enamel junction; FGFR2 = fibroblast growth factor receptor 2; micro-CT = micro-computed tomography; MDCT = multidetector computed tomography; MRI = magnetic resonance imaging; nano-CT = nanocomputed tomography; OPG = orthopantomograph; PET = positron emission tomography.

“…Very large changes of dental work can complicate identification, too. Furthermore, the unsuccessful identifications can possibly be a result by the lack of image quality [3,16]. Dental characteristics could be insufficiently extractable in an overexposed radiograph.…”

“…Therefore, cooperation between forensic medicine and radiology is recommended. The acquisition process can be simplified with the application of postmortem computed tomography data and a multiplanar reformation (MPR) to create a synthesized PR [16,21]. However, synthesized MPR images are slightly blurred and show minimal geometric distortion as well as reduced superimposition of oral structures [16,21].…”

ZUSAMMENFASSUNGZiel In der forensischen Odontologie ist der Vergleich von Ante-mortem und Post-mortem Panorama-Röntgenauf-nahmen (PR) eine zuverlässige Methode zur Personenidentifizierung. Das Ziel ist die automatische Identifizierung von unbekannten Personen mithilfe eines Vergleichs von Antemortem und Post-mortem PR unter Anwendung der Computer Vision. This document was downloaded for personal use only. Unauthorized distribution is strictly prohibited. Material und Methoden Materials and MethodsThe study includes 43 467 PRs from 24 545 patients (46 % females/54 % males). All PRs were filtered and evaluated with Matlab R2014b including the toolboxes image processing and computer vision system. The matching process used the SURF feature to find the corresponding points between two PRs (unknown person and database entry) out of the whole database.Results From 40 randomly selected persons, 34 persons (85 %) could be reliably identified by corresponding PR matching points between an already existing scan in the database and the most recent PR. The systematic matching yielded a maximum of 259 points for a successful identification between two different PRs of the same person and a maximum of 12 corresponding matching points for other nonidentical persons in the database. Hence 12 matching points are the threshold for reliable assignment.Conclusion Operating with an automatic PR system and computer vision could be a successful and reliable tool for identification purposes. The applied method distinguishes itself by virtue of its fast and reliable identification of persons by PR. This Identification method is suitable even if dental characteristics were removed or added in the past. The system seems to be robust for large amounts of data.

Pesqui Bras Odontopediatria Clín Integr. 2020; 20:e5262. https://doi. AbstractObjective: To approbate the complex approach for assessment of second molar mesialization outcomes with the use of orthodontic mini-implants. Material and Methods: The sample consisted of 62 patients, divided into study (n=32) and control group (n=30). Mesialization procedure in the study group was conducted with the use of braces system and orthodontic mini-implants as additional anchorage devices, while in control group mesialization was provided only with the use of the brace system. Dynamic registration of bone level changes and the entire range of tooth movement were carried out on digital orthopantomograms obtained with the use of Planmeca ProMax 2D. Results: Findings of orthopantomographic (OPG) analysis have shown that cases of second molar mesialization with the use of mini-implants as temporary anchorage characterized with more stable conditions of bone levels around displaced teeth compare to cases, where mesialization was provided only with the use of braces systems without any additional anchorage. The terms of treatment in the study group with the use of dental mini-implants as the anchorage was reduced by 8.8 ± 0.12 months compared to the control group (p<0.05). Conclusion: The use of orthodontic miniimplants as anchorage constructions during the mesialization of the mandibular second molars contributes to the reduction of treatment duration and support the more prognostic movement of teeth, that does not provoke significant pathological changes in the levels of the surrounded alveolar ridge and minimize the risk of associated periodontal complication occurrence.
