Detailed explanation-1: -The adult human pelvis is useful to estimate age because it contains three age indicators-the pubic symphysis, auricular surface, and acetabulum.

Detailed explanation-2: -Methods for aging adult skeletal remains typically use measurements from two bones in the pelvis: the ilium and the sacrum. [1] Since it is common for forensic anthropologists to receive incomplete skeletons that may not include the pelvis, they often rely on past experience to estimate age at death.

Detailed explanation-3: -Measuring the length of long bones can give an estimate of age for children, but this technique is useful only until bones have stopped growing. The tibia completes growth at about age 16 or 17 in girls, and 18 or 19 in boys. For toddlers to teenagers up to age 21, teeth are the most accurate age indicators.

Detailed explanation-4: -Results. The essential components of age estimation are the history, physical examination, X-rays of the hands, panorama films of the jaws, and, if indicated, a thin-slice CT of the medial clavicular epiphyses, provided that there is a legal basis for X-ray examinations without a medical indication.
