치석에는 박리상피세포, 백혈구 등이 포함되어 있어 이들의 핵 내에 있는 DNA의 유전자형을 찾아내 개인식별을 할 수 있을 것으로 추정된다. 본 연구에서는 치석만으로 개인식별이 가능한지를 알아보고자 40명으로부터 채취한 치석을 증류수에 세척한 군과 세척하지 않은 군으로 나누어 DNA를 추출하고 중합효소연쇄반응법을 이용하여 증폭절편다형(AMP-FLPs)을 실시한 후 성별검사를 위한 X-Y homologous amelogenin gene과 유전자지문검사를 위한 STR유전좌위 LPL, F13B, Triplex(F13A01, FESFPS, vWA) 등 6개의 유전자를 검색하여 - X-Y homologous amelogenin gene과 LPL, F13B는 각각 증폭하였으며 F13A01, FESFPS, vWA 세 유전자는 동시에 증폭하였음 - 다음과 같은 결과를 얻었다. 1) X-Y homologous amelogenin gene 검색으로 세척군에서 27개의 검체 중 8개, 비세척군에서 13개 중 11개에서 성별검사가 가능하였다. 2) LPL유전자는 세척군, 비세척군에서 각각 27개 검체중 2개, 13개 검체 중 5개가 검색되었으며 3개의 대립유전자(10, 11, 12)와 4개의 유전자형 (10-10, 10-11, 10-12, 11-12)이 나타났다. 3) F13B유전자는 세척군, 비세척군에서 각각 27개 검체 중 1개, 13개 검체 중 4개가 검색되었으며 2개의 대립유전자(9, 10)와 2개의 유전자형(9-10, 10-10)을 관찰하였다. 4) F13A01유전자는 비세척군에서만 13개 검체 중 3개가 검색되었고 3개의 대립유전자(3.2, 4, 6)와 3개의 유전자형(3.2-3.2, 4-5, 4-6)을 관찰하였고, 세척군에서는 나타나지 않았다. 5) FESFPS유전자는 비세척군에서만 13개 검체 중 1개가 검색되었고 유전자 형은 11-12로 나타났다. 6) vWA유전자는 세척군, 비세척군에서 각각 1개씩 검색되었으며, 3개의 대립유전자형(14, 16, 17)와 2개의 유전자형(14-16, 14-17)을 관찰하였다. 이상의 결과를 종합해 볼 때, 치석은 X-Y homologous amelogenin gene증폭을 통한 성별검사와 단일 STR유전좌위 증폭을 통한 유전자지문형 검사에는 유용하나 복합 STR유전좌위의 검색에는 부적합한 것으로 나타났으며 법의학적시료로 응용이 가능한 것으로 사료된다.

This study intends to find usefulness of the computer assisted dental identification in mass disaster. The variety of dental characteristics was investigated through the research of dental records of 508 adults. And a computer assisted simulation program was used to evaluate the selectivity of dental identification. Findings were as follows : 1. Combinations of dental characteristics were found 155 types. The most various dental characteristic was showed on the mandibular first molar. 99.0% of subjects had dental characteristics for dental identification. 2. The posterior teeth, in comparison with anterior teeth, showed higher selectivity in dental identification which was enhanced by information on the material, type and cavity of the restoration. 3. The variety of dental characteristics was mainly found on the combinations of missing tooth with the material, type and cavity of the restoration. 4. The computer assisted dental identification program, with informa- tion about one's tooth state, made individual identification possible when there was only a part of the teeth in a corpse. 5. The computer assisted dental identification had considerably high selectivity based on the variety of dental characteristics. And it was also performed faster and preciser than the existing identification methods. Based on the results of this study, there are various combinations of the feature of the tooth itself with dental characteristics caused by a certain type of treatment on the teeth. And using the computer assisted dental identification program based on this, dental identification can be more efficient economically and more useful than any other forensic identification methods.

The teeth are important object of study in forensic odontology. With regard to ancient Korean teeth of Hupori, the authors studied the size and morphology of the teeth, dental caries and degree of attrition and determined the sex and age. The results are as follows: 1. In the morphology of teeth, there was little difference between the Hupori teeth and the moderan human teeth, but in Hupori teeth, the shovelling of lingual fossa of mixillary incisors were prominent. 2. In comparision of crown size, there was little difference between the modern human teeth and Hupori teeth, crown wide of maxillary incisors and mandibular first molars in Hupori teech were slightly greater than the modern human teeth. 3. In the examination of the dental caries, 7 out of 23 permanent teeth examined were decayed, but none of 14 deciduous teeth. 4. The degrees of teeth atrition were mostly slight. 5. As a result of sex and age determination, the proportion of males to females was similar, the age of teeth was identified as twenties mostly.

Human bite marks may be comples injuries and the teeth, either alone or in combination with other mouth parts, damage bitten material in a number of ways. In order to assist with the recognition and interpretation of possible bite marks, it is important to have an appropriate way of describing them. Authers have studied bite mark on suspect's finger and detailed examination of scientific evidence led the dental investigation to the conclusion that there was a positive match between the dentition and the bite mark on the suspect's finger.
