Abstract:
Objective To study the morphological changes, human bitemarks were made on the living and dead canine skin. Method The changing patterns of the human bitemarks were recorded with morphological parameters measured. The relationships among the patterns of the bitemark, tooth area, time, ocdusal force, tooth width and thickness were analyzed by multiple progressive regression. Results The multiple progressive regression equations of the morphological changes of human bitemark were established: S=-6.96-1.68?10 2T-0.11F +2.21W+3.75H(Live dog test,T
