Age of death estimate
The age of death estimate is a branch of human biology . Their methods were and are developed and used in forensic medicine , prehistoric and forensic anthropology . It is used to estimate the biological age of corpses.
The term age of death determination is synonymously used, but feigns an accuracy which is not the case - it can only have one chance and one age range be specified within which the individual is deceased.
Methods
On the bit
The tooth breakthrough times that Wurzeldentintransparenz , the racemization of aspartic acid in dentin and the degree of Zementannulation used to estimate the age, the age of children and adolescents can be determined relatively accurately. For adults, an age estimate with an accuracy of ± 5 years, according to other authors, ± 10 years is possible.
On the skeleton
The aging process is determined by examining four skeletal regions.
At the head an investigation is carried out of the ossification of the cranial sutures : the coronal suture ( coronal suture ) between the frontal and the parietal bone , the lambda seam ( lambdoid suture ) between the parietal and occipital bone , the sagittal suture ( sagittal suture ) between the two parietal bones and the frontal suture ( frontal suture ) between the two front bones. The seams close with age.
The pubic relief is examined on the pubic bone and the bone structure on the upper arm and thigh bone. The bone structure is broken down with age.
In children and adolescents, the state of adhesion of the growth plates (epiphyseal plates) is also used, which means that an age estimate up to the age of 30 can be made relatively precisely.
Wear and tear on the spine and joints of the postcranial skeleton are also assessed.
X-ray fluorescence analysis is available as a non-destructive analysis method .
