Abstract

One of the challenging aspects of fire investigations is the multidisciplinary basis of the exploration. It involves investigations concerning the origin of fire, its cause as well as the identification of victims. Victim identification in fire disasters becomes nearly impossible owing to complete destruction of soft tissues. In such circumstances teeth may prove to be of value since they are extremely hard and are encased both hard and soft tissue casing. With this foundation a pilot study was done to examine the morphological and histological changes in teeth subjected to extreme heat under laboratory conditions. Physical and microscopic findings were correlated to the temperature and duration of exposure. Morphological changes were to be consistent with the temperature used. Microscopic examination revealed definite histological patterns which were explicitly seen at a particular temperature range only. Also, the various dental hard tissues could be visualized and interpreted at temperatures as high as 350OC, at which rest of the body becomes completely defaced. The consistency of morphological changes, the histological patterns and the integrity of teeth at temperatures that are commonly encountered in common domestic fires, indicates that, evaluation of incinerated dental remains may provide additional investigative avenues in victim identification.
