Teeth, in the living as well as the dead, are the most useful objects in the field of forensic investigation. Their ability to survive in situations like mass disasters makes them important tools in victim identification. Though the morphology and structure is similar in both men and women, there are subtle differences. Variation in dental size can give a clue about differences between the sexes. Many authors have measured the crowns of teeth in both men and women and found certain variations. Canines, reported to survive air crash and hurricane disasters, are perhaps the most stable teeth in the oral cavity because of the labiolingual thickness of the crown and the root anchorage in the alveolar process of the jaws. Measurement of mesiodistal width of the mandibular and maxillary canines provides good evidence of sex identification due to dimorphism.
Death due to burns is an important public health problem. Suicide by burning is uncommon in the Western world compared with Asian countries. This study presents retrospective research carried out in the tertiary care teaching hospital of Kasturba Medical College, Manipal, Southern India, between January 1993 to December 2003 (11 years). Out of a total of 343 burns deaths during the above-mentioned period, 39 were victims of suicide. The majority of deaths (46.1%) occurred in the 21-30 years age group, with a preponderance of the female sex (79.5%). Most of the victims belonged to the Hindu religion and the incident occurred mostly during the daytime. In the overwhelming majority of cases, the incident occurred at home (97.4%). In all cases kerosene was the accelerant and flame was the causative agent. In more than fifty per cent of cases, the total body surface area (TBSA) involved was more than 80%. Dowry demands and harassment were the reasons for committng suicide in 12 cases. More stringent laws and empowering female independence, both mentally and economically, will reduce suicidal burns in young women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
