Ectopic maxillary third molar in Early Pleistocene Homo antecessor from Atapuerca-Gran Dolina site (Burgos, Spain). AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 2020; 171:733-741.

Abstract
OBJECTIVES Here we describe the case of an ectopic maxillary third molar (M3 ), preventing the eruption of the M2 , in the individual H3 of the hominin hypodigm of level TD6.2 of the Early Pleistocene site of Gran Dolina (Sierra de Atapuerca, Spain). MATERIALS AND METHODS The fossil remains from the TD6.2 level of the Gran Dolina site (about 170 specimens) are assigned to Homo antecessor. Different geochronological methods place these hominins in the oxygen isotopic stage 21, between 0.8 and 0.85 million years ago (Ma). The immature individual H3 is represented by an almost complete midface (ATD6-69), preserving various teeth in situ. We used high-resolution microtomograhy (mCT) to investigate the abnormal position of the left M3 , virtually reconstruct M2 , and M3 as well as assessing the development stage of these. Finally, we compare this case with extinct and extant populations. RESULTS Based on the identified signs, we suggest that individual H3 suffered from a unilateral impaction of the M2 as a result of the ectopic position of the developing M3 . DISCUSSION We conclude that the most likely etiology for the ectopic position of the M3 is the lack of space in the maxilla. We discuss possible contributing factors, such as morphometric aspects of the maxilla and the early mineralization of the M3 , to support the M2 impaction. Finally, due to the early age at death of this individual we did not identify any secondary lesion associated with the M2 impaction.

Forensic odontology involvement in disaster victim identification. Forensic Sci Med Pathol 2011; 8:148-56. [PMID: 21952930 DOI: 10.1007/s12024-011-9279-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/25/2011] [Indexed: 10/17/2022]
Abstract
Forensic odontology is one of three primary identifiers designated by Interpol to identify victims of mass casualty events. Forensic odontology is involved in all five phases-Scene, Postmortem, Antemortem, Reconciliation and Debrief. Forward planning, adequate funding, international cooperation and standardization are essential to guarantee an effective response. A Standard Operation Procedure should be utilized to maximize quality, facilitate occupation and health issues, maintain security and form a structure to the relief program. Issues that must be considered in the management of the forensic odontology component of disaster victim identification are given in "Appendix 1". Each stage of the disaster, from initial notification to debrief, is analyzed and a comprehensive checklist of actions suggested.
