“…However, hypercementosis is an age-related response to heavy masticatory load (Pinheiro et al 2008) whereas root resorption is an effect of local occlusal overload (Schätzle et al 2005). Hypercementosis is thus more likely to be the cause than the effect of root resorption (Schätzle et al 2005). These observations indicate that caution is warranted when interpreting population-specific differences in hypercementosis in terms of different masticatory regimes.…”

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...

Résumé -Introduction : L'ankylose est un phénomène courant, en denture temporaire stricte ou mixte. Elle concerne essentiellement les secteurs postérieurs pour les dents lactéales et le secteur antérieur pour la denture adulte. Observation : Une enfant de 6 ans sans antécédents médicaux a consulté pour la présence d'une dent temporaire « ré-incluse ». Discussion : L'évolution d'une ankylose est le plus souvent défavorable. Les traitements sont discutés en fonction du type de denture. Abstract -Ankylosed primary tooth: a case report. Introduction:Tooth ankylosis is a current phenomenon, especially in strict or mixed deciduous dentition. It concerns essentially posterior sectors for deciduous teeth and anterior sector for adult dentition. Observation: A 6-year-old girl with no medical history has consulted for the presence of a primary tooth "re-included". Discussion: The ankylosis evolution is often unfavourable. Treatments depends on the dentition.

The treatment of external root resorption and associated periodontal defect can be challenging to the most ingenious clinician. A correct diagnosis and an understanding of the etiology and dynamics of root resorption, which is the progressive loss of dentin and cementum through action of osteoclastic cells, are critical for effective management. The article describes the management of an external root resorption in maxillary central incisor where a combined endo-perio management strategy was implemented. Cone beam computed tomography was used as an adjunctive diagnostic aid. A combined approach using biodentine for root surface repair, bone graft, collagen membrane, and platelet-rich fibrin to address the associated osseous lesion appears to be viable modality in treatment of the same. After a follow-up period of 12 months, the patient was found to be asymptomatic. Postoperative radiographs also demonstrated satisfactory bone fill and arrest of the resorptive lesion.

Progressive, Generalized, Apical Idiopathic Root Resorption and Hypercementosis

Abstract: At present, there is no preventive or therapeutic regimen for the type of root resorption seen in this case report. Treatment usually consists of the extraction of teeth with advanced lesions.
