A biomechanical study on the morphological changing process of human bitemarks / 生物医学工程学杂志

ABSTRACT

This is a biomechanical research in the morphological changing process of human bitemarks on the skin of dogs. The human bitemarks were made on the live and dead dogs by different tooth and occlusal force. The changing process of the bitemarks were recorded for a long time and its related morphological parameters were measured. Then multiple stepwise regression analysis was made to disclose the relationship of the shape of the bitemarks to occlusal force, time, and tooth area, tooth width and thickness. The mathematic relationship of the morphological changing process of the bitemark with occlusal force, time and tooth shape was established.
