Abstract
Forensic anthropologists employ in estimating stature from fragmented body parts or human skeletal remains. This study aimed at investigating the inter-racial difference between adult Egyptian and Bengali populations regarding the body stature and tibial length, developing regression equation formulae using the percutaneous length of tibia (PCTL) to estimate stature. Four groups of adult male and female Egyptian and Bengali subjects aged ˃21 were recruited randomly. Body height and PCTL were measured using the standard anthropometric technique. The means of the stature of the studied groups exhibited significant differences between all groups (p<0.001) except in Egyptian females versus Bengali male (p=0.067). There was no significant difference within the same sex of both ethnic groups regarding the tibial length (Females p=0 .490) and (Males p=0.905).The measured parameters of males were significantly higher than the corresponding female values. The linear regression equations derived for male and female Egyptian were 94.080+2.145 x T (± 3.57) and 76.617+2.375 x T (± 3.89), respectively. Those for male and female Bengali were 92.500+1.870 x T (± 2.93) and 105.563+1.473 x T (± 2.39), respectively. It was concluded that the derived equations are flexible and retain realistic standard errors that can be used for stature estimation using the length of an intact mutilated leg. These equation formulae are Sex and ethnic specific. Thus, they should be endorsed in anthropological studies for stature estimation among the ethnic groups under this study.

Forensic pathologist is responsible for establishment of the identity of the deceased during post-mortem examination which is a challenging task
The standards for stature estimation are grounded on two main methods: the anatomical method, which necessitates the presence of a whole skeleton, or the mathematical method, that needs a complete long bone to employ multiplication factors or regression formulae
Bengali populations are known as Bengalis or Bengalees who are related to an Indo-Aryan ethnic group. They are inhabitants People’ Republic of Bangladesh and Indian state of West Bengal located in the northwestern part of South Asia (Minahan, 2012), while the Egyptian are relevant to the Mediterranean Sea ethnic class which is a sub-race group of Caucasian race (Baum, 2006) Aim of the study This study aimed at investigating the inter-racial difference between adult Egyptian and Bengali population samples regarding the body stature and tibial length, developing regression equation formulae using the percutaneous length of tibia to estimate the body stature
Summary
Forensic pathologist is responsible for establishment of the identity of the deceased during post-mortem examination which is a challenging task. As a result of the increased incidence of terrorism, the development of transportation facilities, aircraft crashes, and natural mass disasters; mutilated, dismembered and skeletonized materials become more common. In these cases, the forensic anthropologist is required to assist in partial identification by compiling a biological profile so; the possibility of individual identification can be narrowed (Saukko and Knight, 2016). The standards for stature estimation are grounded on two main methods: the anatomical method, which necessitates the presence of a whole skeleton, or the mathematical method, that needs a complete long bone to employ multiplication factors or regression formulae. This mathematical method estimates the stature by deducing correlation between personal measurements of bones to living body height (Lundy 1985; Ahmed 2013)
