Sexual dimorphism of root length on a Greek population sample

Contribution of dental tissues to sex determination in modern human populations

“…Both their crown (a, Vc) and root (Vr, Vc/Vt) were larger and, therefore, the overall size of the tooth (Vt). These results are in agreement with those obtained in the literature on canine crown dimensions (mesiodistal and buccolingual widths) in modern humans (Acharya et al, ; Ateş, Karaman, Işcan, & Erdem, ; Peckmann et al, 2015; Pereira et al, 2010), as well as, they also support the conclusions reached by Zorba, Vanna, & Moraitis () and Garn et al (), who argued that root dimensions of canines offer a reliable method for determining sex. Although, most of researchers who have studied sexual dimorphism in teeth have pointed out the high dimorphism of canines (Acharya and Mainali, ; Acharya et al, ; Garn et al, ; Hillson, ; Lund and Mörnstad, ; Rao et al, ; Schwartz and Dean, ), a number of them have also observed differences in size of male and female premolars and molars (Prabhu and Acharya, ; Viciano, López‐Lázaro, & Alemán, ; Zorba, Moraitis, & Manolis, ), and, to a lesser extent, in their incisors (Garn et al, ; Staka, Asllani‐Hoxha, & Bimbashi, ).…”

A novel method for sex estimation using 3D computed tomography models of tooth roots: A volumetric analysis

“…This result is in accordance with the results of Tuttösí and Cardoso's (2015) study of tooth cervical measurements and Zorba, Vanna, and Moraitis's (2014) study of root length measurements. The maxillary canine was the next tooth showing the highest percentage of sexual dimorphism; this tooth has also been reported high for sexual dimorphism in crown, cervical, and root length measurements in the literature (Garn, Cole, & Van Alstine, 1979;Cardoso, 2008;Zorba, Vanna, & Moraitis, 2014). These teeth also provided the highest classification accuracy rate for the univariate discriminant function analysis.…”

“…Other studies have shown that the length of root measurements are highly sexually dimorphic and therefore can be used for sex estimation (Garn, Van Alstine, & Cole, 1978;Harris & Couch, 2006;Zorba, Vanna, & Moraitis, 2014). In addition, root measurements are not affected by wear, as is often the case with crown measurements (Hillson, FitzGerald, & Flinn, 2005).…”

Growth hormone receptor gene is related to root length and tooth length in human teeth

“…In this study, the association of the root lengths and tooth length with GHR variants was investigated in CBCT images in a large number of subjects and compared with the results of a number of previous reports. 21,[34][35][36][37][38][39][40] A maximum 8.4-mm difference in U3-R was found between the current cohort and Finnish males, 34,35 suggesting that the crown and root lengths in Japanese may be smaller than those in Europeans, excluding those of U1, U2, L1, and L2. Interpopulational and regional differences in the crown width are well known.…”
