The purpose of this study is to review and present the aims and the applications of forensic dentistry. Dental science plays a vital role in the detection and solution of crime. Forensic dentistry compares and demonstrates post or ante-mortem dental findings to identify an unknown body. Facial reconstruction is a method used in forensic anthropology to aid in the identification of skeletal remains. Age estimation is a process of particular interest in cases of forensic dentistry. Root dentine translucency of single-rooted teeth is the only parameter giving accurate results for age estimation. Also, a dental practitioner must be able to identify and report to the authorities any kind of child or elder abuse and neglect. Thus, the analysis of bite marks is a major aspect for Forensic dentistry. Terrorism and mass disasters are sad realities of modern life. The Forensic dentist has the obligation to know how to provide immediate health care and how to collect and extract all findings. However, physicians receive minimal training in oral health, dental injury and diseases. This is the reason why they may not detect dental aspects of Forensic dentistry. Therefore, physicians and dentists are encouraged to collaborate so as to increase the prevention, detection and treatment of these conditions.
