Abstract

Based on the alteration of microstructure and gross features caused by long term fate of bony substance a model of decomposition of bone mineral is outlined. Destruction of the corps by microorganisms leads on the whole to an acid milieu. Hence hydroxyapatite is turned into brushite, which is more soluble in acid media. As this mineral is formed in a space consuming way, the expanding brushite-masses support mechanical destruction of bony substance by cracking the lamellary systems. Both mechanical stress by formation of brushite and transformation of hydroxyapatite to this mineral compound are main features for dead bone decomposition.

摘要

基于骨物质长期命运导致的微观结构和大体特征的改变,勾勒出了骨矿物质分解的模型。微生物对骨体的破坏总体上导致酸性环境。因此,羟基磷灰石转变为透钙磷石,其在酸性介质中更易溶解。由于这种矿物质以消耗空间的方式形成,不断膨胀的透钙磷石团块通过使板层系统破裂来支持骨物质的机械破坏。透钙磷石形成产生的机械应力以及羟基磷灰石向这种矿物化合物的转变都是死骨分解的主要特征。
