Background: The determination of age and sex is crucial for establishing human identity. The mandible is an accessible and durable bone that is very useful in this respect. Aim:To assess the efficacy of measuring the mandible ramus length in the identification of age and sex in a group of Egyptians. Subjects and Methods:The length of the ramus of the mandible was measured in lateral craniofacial scans of 213 individuals (99 males and 114 females) with an age range of 7-58 years using cone-beam computerized tomography (CBCT). Results:Sexual dimorphism was not observed until age of 17 years in this sample. There was not found any significant differences in the length of the ramus of the mandible between males and females in the age range of 7 to less than 17 years (P-value = 0.2495). There was a significant difference between males and females for the mean length of the ramus in the age range of 17 to 58 years (P-value < 0.0000). It predicts sex with an accuracy of 67%. There was a positive correlation between and (age) and log e (ramus length) (r=0.73, P-value < 0.0001 for females and r=0.85, P-value <0.0001 for males). Therefore, it was possible to calculate each individual's age based on his or her mandible ramus length. Conclusion:The mandibular ramus length is valuable in age estimation and less valuable in sex determination. Computerized tomography examination is a safe and an accurate procedure with minimal radiation exposure, and provides valuable precise information regarding mandible measurements.

ABSTRAK ABSTRACTHistomorphometry method, the quantitative study of histology, is a useful method to estimate age of death in the present and ancient skeletal remains by measurable morphology of osteon. This method, which reduces individual bias and difference in the level of experience for estimation of age, is useful for constructing paleodemographic models and forensic identifications when adult fragmentary skeletal remains are encountered. Most parts of skeletons that are studied by histomorphometry method are femur, tibia, rib, and clavicle. Clavicle bone has 5

“…There are few methods used by forensic scientists whenever the issue of age assessment arises and as such several approaches have been developed. These methods include the use of dental eruptions periods [4,5,6], time of epiphyseal fusion of some bones and micro-scopic or histological features of cortical bones [7,8,9], morphology of the pubic symphysis and auricular surface of the Ilium [10,11,12] the skull and length of long bones [13,6,7], sternal ends of the 3rd, 4th and 5th ribs [14,15]. These foremost macrostructural approaches have lots of limitations as only some bones like the pelvic bone and some long bones give reliable results [16].…”

Background. Age estimation is crucial in creating the biological profile of unknown skeletal remains and recently there is emphasis on the need to develop population specific forensic baseline data for easy identification of these remains. Objective. The aim of this study is to estimate age from the histomorphometric features of the bones of Nigerians. Methods. Fragments of non-pathologic bone samples were collected during orthopaedic procedures. Ground sections were prepared using Modified Frost’s manual method of bone preparation to determine the following histologic parameters; haversian canal diameter (HCD), primary and secondary osteons, number of osteon fragments and non-haversian canal as well as haversian canal area (HCA). 29 subjects aged 35 to 85 years old were used for the study. Bone fragments included samples from the femur, tibia, humerus, and the vertebrae. Data obtained were subjected to descriptive statistics, Pearson’s correlation, bivariate regression equation, Student t-test and analysis of variance (ANOVA). Results. The mean age for our population was 58.86 years old. ANOVA showed significant variation in the average HCD for the various regions: humerus=8.45±2.48, femur=7.09±4.06, tibia=8.70±2.52 and vertebrae=3.69±0.73. There was a strong inverse relationship between age and primary osteons. The total number of osteon fragments increased with age while total number of primary osteons and average HCD decreased with age. The HCA, though statistically insignificant, also decreased with age. Conclusion. Our findings show that three histomorphometric parameters showed significant correlation with age: osteon fragments (OS-f), primary osteons (OS-p) and HCD. The histomorphometric parameters were therefore relevant in age estimation. Objective: The aim of this study is to estimate age from the histologic features of the bones of Nigerians.
