There are many methods for identifying the victims of murder. Scientist are coming up with more ways to identify the bodies of victims and help come up better and more complex tools to help in this endeavor. In this paper I will discuss the many different ways of identifying bodies. Forensic dentistry is used typically when human remains are found and reported to the police who then initiate a request for dental identification. Often a presumptive or tentative identification is available (ie wallet or driving license may be found on the body) and this will enable antemortem records to be located. In other instances, the geographical location in which the body is found or other physical characteristics and circumstantial evidence, may enable a putative identification to be made, frequently using data from the missing persons’ database. Antemortem records are then obtained from the dentist of record. The forensic dentist produces the postmortem record by careful charting and written descriptions of the dental structures and radiographs. If the antemortem records are available at this time, postmortem radiographs should be taken to replicate the type and angle of these. PM Odontogram

Once both records are taken a comparison should be done between the two of them. A methodical and systematic comparison is required, examining each tooth and surrounding structures in turn. While dental restorations figure significantly in the identification process, many other oral features are assessed. Such additional features play an increasingly important role in those individuals with minimal restorations. Some discreprencies can be explained between the antemordem and the postmordem Examples include teeth extracted or restorations placed or enlarged (ie MO amalgam that is now MOD). Figure 1 illustrates explainable discrepancies.
