About This Presentation

Description : Check out this medical PowerPoint presentation titled "FORENSIC ODONTOLOGY”.

This medical PowerPoint presentation is about forensic odontology, the branch of forensic science that uses dental evidence to help identify human remains, establish the identity of individuals, and investigate crimes. It involves the use of dental knowledge and techniques to analyze and interpret dental evidence, such as teeth, dental records, and bite marks.

Forensic odontologists work with law enforcement agencies, coroners, and medical examiners to help identify human remains that are too damaged or decomposed to be identified through traditional means. They can also assist in identifying individuals involved in mass disasters, such as plane crashes or natural disasters.

In addition to identification, forensic odontologists can also use their expertise to analyze bite marks left on victims in cases of assault or sexual assault. They can compare the bite marks to the dental records of potential suspects to help establish or refute their involvement in the crime.

Overall, forensic odontology plays a critical role in the criminal justice system, helping to provide valuable evidence in the investigation and prosecution of crimes.

Functions of Forensic Odontology Id unknown human remains through dental records. Assist at the scene of a mass disaster. Age estimations of both living and deceased persons. Analysis of bite marks found on victims of attack. ID of bite marks in other substances e.g. wood, duct tape, pencils, leather and foodstuffs. Analysis of weapon marks using the principles of bite mark analysis. Presentation of bite and weapon mark evidence in court. Building a picture of lifestyle and diet at an archaeological site.
