In addition to other specific expertise, forensic science includes anthropology, biology, chemistry, physics, medicine, pathology, phonetics, psychiatry, fingerprinting, and other scientific disciplines. Modern humans have made significant advances in science and technology, but they have also had to deal with a number of brand-new problems, including catastrophic disasters, terrorism, and soaring crime rates. Despite the recent developments in science, technology, and medicine, criminal behaviour has significantly increased in human cultures. The prosecution of the criminal or offenders is required to protect the law and defend the rule of law. Law enforcement and forensic science professionals gather, examine, assess, and present evidence using specific knowledge and techniques in order to convict the offender or solve a crime. Since many years ago, forensic science has gone beyond conventional methods of investigation to help solve the mysteries of numerous lingering cold cases. Teeth act as a reliable biological storage facility for a range of biological information, including information about a person's identity, growth patterns, diet, illness, migratory patterns, geographic origin, and other factors. They are the most resilient structures in the human body, able to endure all kinds of traumatic and taphonomic destructions, making them perfect for identifying the biological identities of people who have suffered severe disfigurement or whose skeletal remains have sustained significant damage. Enamel forms throughout adolescence and does not fundamentally alter afterward, providing long-term proof of significant life experiences like prolonged disease or exposure to stressors from the environment. In forensic or bioarchaeological investigations, they are frequently the only human remains discovered and are more resilient than bones. The most valuable and plentiful source of DNA is from them. The victim's oral health and dental restorations may be a reflection of their socioeconomic status and way of life. For instance, certain professions such as carpentry, shoemaking, music, and tailoring may have particular dental anomalies that can be used to identify the deceased. It is possible to recreate the sequence of events leading up to death by examining the sockets of missing teeth to determine if teeth were pulled forcibly or naturally. The victim has crowded, red teeth, which indicate a brutal demise. Additionally, the palatal rugae, sometimes known as the "fingerprints of the oral cavity," are distinctive to each individual. Whether healthy or broken, a person's teeth might provide insight into their eating habits or ingrained behavioural patterns. Geological characteristics such as soil interfering between the teeth and saprophyte invasion on the tooth dentine or cementum might serve as "locality prints" that pinpoint the location of the victim's death. Diatoms in the mouth or, in some situations, in the tooth pulp can reveal information about drowning fatalities. The elemental and isotopic composition of a person's teeth can provide information about their regional affiliation and migration background. The structure and state of a person's teeth can provide secret information about their health, diet, and tool use in addition to being used to determine their age. Other forensic dentistry treatments include radiographic analysis, elemental and isotopic analysis, bite mark analysis, cheiloscopy, rugoscopy, teeth prints, dental DNA analysis, and so on.
