United States at the Armed Forces Institute of Pathology. Because of this program, the term "forensic odontology" is now familiar in the dental profession and law enforcement agencies. Odontologists or dentists can use dental science to know a person's identity. Teeth can be used as weapons and therefore leave information about a person. This information is key in recognizing abuse among people of any age. Forensic pathology A forensic pathologist is a medical doctor who is an expert in both trauma and disease and is responsible for performing autopsies. He/she applies their extensive knowledge of the human body and possible internal and external inflictions as he/she performs an autopsy, to hopefully ascertain the manner and cause of death. Information derived from the autopsy often greatly assists investigative efforts as well as scene reconstruction. Forensic toxicology Forensic toxicology is the use of toxicology and other disciplines such as analytical chemistry, pharmacology and clinical chemistry to aid medical or legal investigation of death, poisoning, and drug use. The primary concern for forensic toxicology is not the legal outcome of the toxicological investigation or the technology utilized, but rather the obtainment and interpretation of results. Forensic microbiology With recent advances in massive parallel sequencing (MPS), or next-generation sequencing (NGS), forensic microbiology has become an increasingly promising area of research. “Initial applications in circumstances of biocrime, bioterrorism and epidemiology are now accompanied by the prospect of using microorganisms (i) as ancillary evidence in criminal cases; (ii) to clarify causes of death (e.g., drownings, toxicology, hospital-acquired infections, sudden infant death and shaken baby syndromes); (iii) to assist human identification (skin, hair and body fluid microbiomes); (iv) for geolocation (soil microbiome or microbiome of bodies of water); and (v) to estimate postmortem interval (thanatomicrobiome and epinecrotic microbial community)”. Bioterrorism and epidemiology “It is important to remember that biological agents that can be used as weapons are often found in the environment. For this reason, it is always difficult to determine whether infections associated with these bioagents are accidental or purposely started”. While not the first, or only, incidence of bioterrorism, perhaps the most notable case in recent memory involved the sending of at least four anthrax-containing envelopes in the United States in September and October 2001. “At least 22 victims contracted anthrax as a result of the mailings: 11 individuals contracted inhalation anthrax, with 5 of these infections resulting in fatalities; another 11 individuals suffered cutaneous
