Sex estimation based on tooth measurements using panoramic radiographs

“…Sex estimation is an important part in diverse forensic disciplines. In forensic anthropology sex estimation is based on morphological and metrical features of the skeletal bones, such as skull and mandible [4,[7][8][9][10], scapula, clavicle, sternum, humerus, femur, hip and sacrum [8,11]. In forensic medicine, external and internal autopsies and (DNA) analysis of different prelevated biological materials are used [4,6,8].…”

In forensic odontology methods based on metric and non-metric dental features as well as DNA analysis of teeth (parts) are developed for sex estimation [1,4,8].…”

Caracterización de los tejidos dentales caninos permanentes de las poblaciones actuales y del Pleistoceno de la sierra de Atapuerca (Burgos) mediante microtomografía microcomputarizada (micro-CT): dimorfismo sexual y otras inferencias paleobiológicas

“…In most contemporary human populations, males have larger teeth than females (Alvesalo, 1971;Garn, Lewis, & Kerewsky, 1964;Işcan and Kedici, 2003;, exhibiting the canine teeth the highest degree of dimorphism among the different tooth classes (Acharya, Angadi, Prabhu, & Nagnur, 2011;Acharya and Mainali, 2007;Garn, Lewis, & Kerewsky, 1967;Lund and M€ ornstad, 1999;. Mandibular canines are particularly interesting in sex determination of unidentified remains, since they are more resistant to periodontal disease and to severe trauma (Roetzscher, 2013;Nelson, 2014), which increases their chances of being recovered in a good state of preservations. For this reason, several researchers have employed mandibular canines to assess sex differences in size from samples of various geographic regions and diverse population groups Işcan and Kedici, 2003;.…”

“…La mayor parte de estos estudios, incluido el desarrollado por Ditch y Rose, se emplearon los parámetros morfométricos definidos por Moorrees y Reed (1964): el diámetro máximo mesiodistal (MD) y el diámetro máximo bucolingual (BL) de la corona (e.g., Işcan & Kedici, 2003;Ateş et al, 2006;Acharya & Mainali, 2007a;Sabóia et al, 2013; ver también la Figura 1.13 A). Sin embargo, estas variables pueden verse afectadas por ciertas patologías coronales o por el desgaste dental, por lo que en los últimos años se han propuesto medidas alternativas como, por ejemplo: los diámetros cervicales mesiodistal y bucolingual o los diámetros diagonales de la corona (e.g., Hillson et al, 2005;Karaman, 2006;Cardoso, 2010;Viciano et al, 2011, 2013; la longitud de la raíz (Garn et al, 1978;Zorba et al, 2013); la distancia intercanina Ayoub et al, 2014); o el peso húmedo de los dientes . La aplicación de la estadística multivariante a la odontometría supuso un paso adelante en este tipo de investigaciones.…”

“…In contrast to the posterior dentition, tissue proportions of the anterior teeth have been barely studied (Bayle et al, 2017;Le Cabec et al, 2012, 2013Zanolli et al, 2014). Following Martin's pioneering work (1983,1985), some studies have assessed 2D enamel thickness of the canine teeth through the use of a single physical cross section (e.g., .…”
