| Outline of Final Research Achievements |
Unfortunately, Japan has a lot of disasters and unidentified dead bodies. We have to do personal identification for unidentified dead bodies.
Carbon-14 (14C) method is useful for birth dating. Carbon-13 (13C) and other stable isotopes will give clues to the geographical origin. Aspartic acid racemization shows the age at death.DNA testing shows the sex determination, and identification.
Therefore, in this study, we have studied about the estimation of birth dating by radiocarbon, geographical origin by stable isotopes and age at death by aspartic acid racemization using a single tooth. The information of a birth dating, age at death and sex determination and DNA types using teeth could get to identify the remains. It wasn’t possible to research about geographical origin because of a lack of money and time. My future direction is that one single tooth will give us those information.
