WHY TEETH ARE IMPORTATNT SOURCES IN FORENCIS INVESTIGATIONS??-teeth are one of the strongest structures in the body -usually they are resistant to post-mortem decompositions -most materials used by dentist for restorating or replacing teeth are also resistant to post mortem changes -the morphology and arrangement of teeth vary from person to person -dental evidence helps in establishing identity of badly burned, traumatised, decomposed and skeletonised remains
