Age assessment by rib phase analysis in Turks

Area of Science:

• Forensic Anthropology
• Biological Anthropology

Background:

• The Işcan's phase method is a reliable technique for estimating adult age at death using the sternal rib extremity.
• Previous validations were conducted on diverse samples, but not on a modern, geographically and culturally distinct Turkish population.

Purpose of the Study:

• To assess the applicability of Işcan's rib phase standards to a contemporary Turkish population.
• To determine if morphological changes in Turkish ribs align with established age-related sequences.

Main Methods:

• Utilized a sample of 150 males and 144 females with known ages at death.
• Applied Işcan's rib phasing standards (1984, 1985) to the sternal extremity of the fourth rib.
• Analyzed phase estimations using analysis of variance.

Main Results:

• Turkish ribs exhibited morphological characteristics consistent with established phases at nearly identical ages.
• A trend of increasing variation (standard deviation) was observed from phase 5 onwards in both sexes.
• The study confirmed the reliability of the method across different populations.

Conclusions:

• Işcan's rib phase standards are accurately applicable to the Turkish population.
• Morphological aging patterns of the fourth rib are consistent across diverse populations.
• This research is crucial for the accurate application of forensic anthropological methods in medicolegal contexts involving different ethnic groups.
