Summary of "Correlation between pubic bone mineral density and age from a computed tomography sample."

In forensic anthropology, the estimation of age at death is mainly required to establish a biological profile and facilitate individual identification. The Suchey-Brooks (SB) system represents one of the most commonly used and tested methods of assessment based on the morphological characteristics of the pubic symphysis. However, this method has certain drawbacks, including frequently inaccurate estimation for older individuals. The aim of this work was to test the evolution of pubic bone mineral density (BMD) according to age, especially for individuals over 40 years old. We retrospectively studied pubic bones from males (n = 88) and females (n = 113) over 40 years of age undergoing clinical multi-slice computed tomography (MSCT) in a French hospital between November 2017 and April 2018. The results revealed a significant negative correlation between BMD and age for males (R = -0.62) and females (R = -0.55). The intra- and inter-observer reliabilities of the phase allocation were moderate for males (kappa values at 0.72 and 0.65) and strong for females (kappa values at 0.93 and 0.86). Moreover, a significant difference in BMD between stages 6-1 and 6-2 for males was observed. We hypothesize that BMD might help improve the reliability of the SB system for older individuals. In addition to the pubic bone, numerous other anatomical regions such as the area of Ward could represent interesting areas of study in order to relate bone density to age.

Medical and Biotech [MESH] Definitions

The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.

A bone that forms the lower and anterior part of each side of the hip bone.

Decrease, loss, or removal of the mineral constituents of bones. Temporary loss of bone mineral content is especially associated with space flight, weightlessness, and extended immobilization. OSTEOPOROSIS is permanent, includes reduction of total bone mass, and is associated with increased rate of fractures. CALCIFICATION, PHYSIOLOGIC is the process of bone remineralizing. (From Dorland, 27th ed; Stedman, 25th ed; Nicogossian, Space Physiology and Medicine, 2d ed, pp327-33)

Removal of mineral constituents or salts from bone or bone tissue. Demineralization is used as a method of studying bone strength and bone chemistry.

Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES.
