“…This condition entailed chronic root canal infection and apical periodontitis, which ultimately developed into cystic apical periodontitis, a process that is clinically well-documented in modern humans (Nair 2004;Dag Orstavik and Ford 2007). Similar patterns have been found in HG populations from Sweden and The rate of calculus accumulation depends on the alkalinity of the oral environment, which increases the absorption of minerals from the oral fluids (saliva and gingival cervic fluid) (Arensburg 1996;Lieverse 1999;Jin and Yip 2002). Calculus formation is positively affected by protein-rich diets increasing the oral alkalinity (Hillson 1979).…”

“…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...

“…However, dental calculus formation is actually quite variable and complicated. Various systemic factors, including disease, affect the amount of deposition as well as the velocity of deposition of dental calculus (Beiswanger et al, 1989, Lieverse, 1999, Poff et al, 1997, Epstein et al, 1980, Mandel, 1995, Scheie, 1994, Shasha et al, 1983, Eigner et al, 1986and Fujimaki et al, 1998. Levels and location of calculi are population-specific and are influenced by ora1l hygiene habits, diet, age, ethnicity, and use of teeth as tools (White, 1997).…”
