What is latent dental evidence and how is it used in forensic investigations?
Latent dental evidence refers to subtle or hidden dental marks, such as bite marks or dental patterns, left on objects or skin that are not immediately visible. In forensic investigations, this evidence is enhanced and analyzed to match dental records or dental molds, helping to identify individuals or link them to crime scenes.
How is latent dental evidence collected and analyzed in forensic cases?
Latent dental evidence is collected through photography, casting, and digital imaging to capture bite marks or dental impressions. Analysis includes comparing the collected evidence to dental records or bite patterns of suspects, using techniques like overlay method or computer-assisted analysis to identify unique dental characteristics for forensic identification.
How does latent dental evidence differ from other types of forensic evidence?
Latent dental evidence, such as bite marks, is unique because it can reflect the dynamic interaction between teeth and human skin, leaving impression patterns. Unlike DNA or fingerprints, which provide direct identification, dental evidence can be more subjective and reliant on expert interpretation for linking a suspect to a crime.
Can latent dental evidence be used to estimate the age of a deceased individual?
Yes, latent dental evidence can be used to estimate the age of a deceased individual by analyzing the development and wear patterns of teeth, as well as examining dental restorations and other age-related changes in the oral cavity.
What challenges are associated with interpreting latent dental evidence in forensic investigations?
Challenges in interpreting latent dental evidence include the degradation or partial nature of dental impressions, difficulty in matching with incomplete or outdated dental records, subjective interpretation by forensic experts, and variability in dental work or health over time that can alter the dental profile.
