Abstract
KONINCK, Anke De et al. Buccolingual root dimension of permanente mandibular canines as a complementary estimator of sex: a pilot study. Rev Port Estomatol Med Dent Cir Maxilofac [online]. 2021, vol.62, n.4, pp.217-222. Epub Dec 30, 2021. ISSN 1646-2890. https://doi.org/10.24873/j.rpemd.2021.12.852.
Objective:
To evaluate the potential of the buccolingual dimension of the permanent mandibular canine roots as a sex estimator, using midsagittal cone-beam computed tomography images.
Methods:
In this retrospective study, 58 Portuguese patients (27 female and 31 male) aged 18-60 years were assessed. The maximum buccolingual dimension of the cervical root was measured in the midsagittal plane through cone-beam computed tomography images. The Bland-Altman method was applied for the reliability analysis, and a receiver operating characteristics (ROC) curve was obtained for accuracy analysis.
Results:
The buccolingual root dimension on the mandibular canine showed statistically significant differences between sexes (t56 df = 4.871; p<0.0005). The optimal cut-off to differentiate males from females was 6.64 mm. The area under the curve (AUC) was 83.5% (p<0.0005). An overall accuracy of 79% was obtained. The percentage of males correctly estimated was 77.4%, compared to 81.5% of females.
Conclusions:
Our data suggest that canines’ buccolingual root dimension can serve as a complementary tool for sex estimation in a forensic context.
