“…2 for dental wear frequency distribution per population). In order to evaluate dentoalveolar structures and structural changes due to pathology we established a dentognathic pathology classification protocol, which is based on existing clinical classifications (Le Fort 1901;Bjork A et al 1964;Baume LJ et al 1973;McNeill et al 1980;Clarkson and O'Mullane 1989;Varrela and Paunio 1994;Ramachandran Nair et al 1996;Armitage 1999;Floyd et al 1999;Lieverse 1999;Huumonen and Ørstavik 2002;Bakland and Andreasen 2004;Nair 2004;Schulze et al 2006;Hassan R. and Rahimmah 2007;Ismail et al 2007;Selwitz et al 2007;Buitrago-Téllez et al 2008;Ogden 2008;Pinheiro et al 2008;Rosenberg et al 2010). We grouped DP features into 9 classes, and scored each feature according to location, and according to presence/absence or level of expression.…”

Objectives: Due to the scarcity of the fossil record, in-vivo changes in the dentognathic system of early Homo are typically documented at the level of individual fossil specimens, and it remains difficult to draw population-level inferences about dietary habits, diet-related activities and lifestyle from individual patterns of dentognathic alterations. The Plio-Pleistocene hominin sample from Dmanisi (Georgia), dated to 1.77 million years ago, offers a unique opportunity to study in-vivo changes in the dentognathic system of individuals belonging to a single paleodeme of early Homo. Materials and Methods: We analyze dentognathic pathologies in the Dmanisi sample, and in comparative samples of modern Australian and Greenlander hunter-gatherer populations, applying clinical protocols of dentognathic diagnostics. Results: The Dmanisi hominins exhibit a similarly wide diversity and similar incidence of dentognathic pathologies as the modern human hunter-gatherer population samples investigated here. Dmanisi differs from the modern population samples in several respects: At young age tooth wear is already advanced, and pathologies are more prevalent. At old age, hypercementosis is substantial. Discussion: Results indicate that dentognathic pathologies and disease trajectories are largely similar in early Homo and modern humans, but that the disease load was higher in early Homo, probably as an effect of higher overall stress on the dentognathic system. Key words: aging, tooth wear, caries, periodontitisThe Plio-Pleistocene site of Dmanisi has yielded a large sample of hominin fossils associated with abundant and diverse faunal remains and Mode I stone artifacts (Gabunia et al. 2001;Ferring et al. 2011;Mgeladze et al. 2011). Occupation of the site began shortly after 1.85 Ma. The fossil hominin finds are dated to 1.77 Ma (Ferring et al. 2011). Dmanisi thus represents the earliest evidence of Homo outside of Africa. The well-preserved cranial, mandibular and postcranial remains of five individuals are unique in offering detailed insights into patterns of morphological variation within a paleodeme of early Homo, and into patterns of growth and aging Margvelashvili et al. 2013;Zollikofer et al. 2014). The craniomandibular morphology of the Dmanisi paleodeme has been described previously (Gabunia and Vekua 1995;Gabunia et al. 2000;Gabunia et al. 2001;Gabounia et al. 2002;Lordkipanidze et al. 2005;Lordkipanidze et al. 2006;Rightmire et al. 2006;Rightmire and Lordkipanidze 2010;Lordkipanidze et al. 2013;Margvelashvili et al. 2013). Cranial and mandibular morphological variation within the Dmanisi paleodeme is wide, but well within the range of variation seen in modern humans populations, and in populations of chimpanzee subspecies (Skinner et al. 2006;Lordkipanidze et al. 2013;Margvelashvili et al. 2013;Zollikofer et al. 2014). Variation in size, shape and dentognathic features among the Dmanisi mandibles has received special attention and has been studied to address questions of phylogeny, taxonomy, sexual dimorphism, die...

“…Plain film radiography is helpful only in chronic conditions where the moth eaten appearance of bone is evident after considerable osteolytic activity. [5] The use of bone window CT enables high quality imaging of osteomyelitis and is able to define the precise location and extent depending on the appearance of the fascial spaces. [6] Cone-beam computed tomography (CBCT) has gained increased acceptance as a 3D imaging modality, offering an alternative to CT especially in the maxillofacial area.…”

“…There is also a practical reason; DVT is using lower-intensity radiation than conventional CT. Consequently, it makes only the structure of bone density materials visible in details on the acquisition picture but the soft tissue cannot visualized qualitatively [11,37,39,43,65]. In contrast, some cone or pyramidal beam using equipment, scanning with higher intensity X-ray, is able to show the quality of soft tissues (MDCT) [13,14,29,66].…”

The WARM operation mode represents that the CBCT machine was switched on for at least two hours before the scan but no detector calibration was performed. WARM+C WARM+C scan protocol is consistent with the cone beam computed tomography scan with the complete calibration sequence after the warming-up period. The two-hour warming-up period preceded the calibration process. WUP warming-up period 2D 2 dimensional 3D 3 dimensional iv Galen's principal interest was in human anatomy but, from about 150 BC [2], Roman law had prohibited the dissection of human cadavers. Because of this restriction, Galen performed anatomical dissections on living (vivisection) and dead animals, mostly focusing on pigs and primates [3]. This work was useful because the anatomical structures of these animals usually closely mirror those of humans. Galen clarified the anatomy of the trachea, and was the first to demonstrate that the larynx generates the voice [4,5]. In one experiment, Galen used bellows to inflate the lungs of a dead animal. In his work De motu musculorum, Galen explained the difference between motor and sensory nerves, discussed the concept of muscle tone, and explained the difference between agonists and antagonists [5,6].Andreas Vesalius ( This environment, which lasted from the second century (Galenius) to the sixteenth century (Vesalius), developed a strong desire to have the ability to see inside the human body [7]. Development of medical imagingDuring many centuries the only way to visualize the inside of the human body was through dissection. With technical development, scientists had started to investigate the inside of the human body without its opening. In 1881, Alexander Graham Bell attempted to use magnets and sound waves to discover the location of the bullet that eventually killed U.S.President James A. Garfield [8].After a lengthy period, during scientific experiments with various types of vacuum tube equipment, the discovery of X-rays in 1895, by the Bavarian physicist Conrad Röntgen, represented a major breakthrough (Figure 3 A). When X-rays were finally discovered, they found their way to medical applications within months [9]. B C A 3The original discovery by Röntgen, at the Physical Institute, Julius-Maximilian University, Würzburg, Germany, is recorded to be on 8 November 1895 [9][10][11][12][13][14][15][16][17]. During the discovery, he speculated that a new kind of ray might be responsible for the observation.Since 8 th November was a Friday, instead of relaxing over the weekend, Röntgen took advantage of the time to repeat his experiments. In the following weeks he investigated many properties of the new rays he had temporarily termed 'X-ray'. In fact, he virtually lived in his laboratory during that time. The new X-ray is called the 'Röntgen ray' in many languages [18]. Nearly two weeks after his discovery, he took the very first picture using X-rays of his wife Anna Bertha's hand. When she saw her skeleton she exclaimed 'I have seen my death!' (Figure 3 B and C) [10,18]. Röntgen receive the fir...
