Human Stature Estimation Using Cranial and Mandibular Measurements

Background: In forensic anthropology, estimating stature is an essential part of constructing the biological profile of unknown individuals. While long bones are typically used for this purpose, they are often missing or incomplete in forensic contexts. Methods: This study examined the relationship between cranial and mandibular measurements and estimated stature in a sample of 84 identified adult (aged over 18 years) Portuguese skeletons (43 females and 41 males) from two osteological collections. Stature was estimated using Mendonça’s regression model based on humeral length. Four cranial and mandibular measurements were obtained, and intra- and interobserver reliability was assessed. Results: All variables showed statistically significant correlations with stature, although only the mandibular measurement—the distance between the mental symphysis and the mental foramen (SMFM)—and sex contributed significantly to the final regression model. The model explained 51.3% of the variance in stature. Conclusions: These findings suggest that SMFM, a stable mandibular marker, may serve as a useful supplementary indicator for stature estimation in cases where long bones are not available. Further studies with larger and more diverse samples are needed to validate these findings and evaluate their applicability across different populations.
