|Abstract: ||In cases of forensic dental identification, a key factor in the comparison of the dental status of deceased persons with antemortem dental records is the matching of dental restorations in individual teeth. Many studies have been performed showing the prevalence of dental interventions. This has mostly been performed by counting the numbers of decayed, missing and filled teeth (DMFT) in each mouth without detailed data collection on a per-tooth basis. The purpose of this study was to investigate the research question: to what extent would data on the distribution and prevalence of restoration types in the human dentition facilitate forensic identification? A database program was developed to allow efficient collection and collation of dental trait information. Provision was made for storing information relating to a subject's individual teeth, such as restorative materials used and surfaces filled. Other data, such as missing teeth, caries status on a per-individual tooth basis and presence and details of types of prostheses may be stored. iii Data from patients attending a private group practice in Hobart was collected and a system was devised to enable the likelihood of dental trait occurrence to be calculated in cases of forensic dental identification. The capabilities of the system are demonstrated in a series of mock cases of dental identification. An opportunity to make use of the database for which it was designed arose in relation to the analysis of person identification evidence in a murder trial at the Tasmanian Supreme Court. The use of this reference database in evidence invoked lengthy debate involving the judge, crown prosecutor and defence barristers. The resulting voire dire was resolved in favour of conclusions drawn from the use of the database being admitted in evidence. The legal precedent set in the Marlow trial may possibly offer encouragement for practising odontologists to further the concept of establishing and using reference databases of dental traits in population groups in other parts of Australia.|
