Odontometric parameters in human mandibular molars for sex estimation in a forensic context is the new article published by CIAS’ researcher Vítor Matos in collaboration with Sofia F. Franco (IINFACTS-Institute of Research and Advanced Training in Health Sciences and Technologies, Department of Sciences, University Institute of Health Sciences (IUCS), CESPU, CRL, Gandra, Portugal), Álvaro Azevedo (Faculty of Dental Medicine, University of Porto, Portugal), Daniel Mongiovi (IINFACTS), and Alexandra Teixeira (IINFACTS).
Sex estimation is an important step in the identification of human skeletal remains, since it reduces the number of potential matches to approximately one-half. The os coxae and skull are considered the most dimorphic skeletal elements; however, when unavailable, teeth may be used alternatively. In this work, the authors aimed to evaluate the usefulness of specific odontometric parameters from the mandibular first molar – mesiolingual-distobuccal distance (MLDB), mesiobuccal-distolingual distance (MBDL) and mesiodistal distance (MD) – on sex estimation in a Portuguese sample composed of 135 mandibles (78 males; 57 females; ages at death ranging from 18 to 59 years old) selected amongst the 505 individuals of the Coimbra Identified Skeletal Collection (University of Coimbra). Since canines are considered the most accurate teeth for sexual assessment, comparison between first molar parameters and canines mesiodistal dimensions (MD) was performed.
Present results indicate that although mandibular molar dimensions are useful for sex estimation, the canine should be prioritized when available to perform this task. The complete work is available online, in HERE.
