Final answer:
Wax impressions and plaster casts of teeth are used in forensic odontology to compare dental remains found at crime scenes with dental records of missing persons for identification purposes.
Step-by-step explanation:
Forensic odontology is a branch of forensic science that involves the examination of teeth and dental records for the purpose of identification. Wax impressions and plaster casts of teeth play a crucial role in forensic odontology as they can be used to compare dental remains found at crime scenes with dental records of missing persons. By analyzing the similarities and discrepancies between the two, forensic experts can help in identifying unknown individuals.
For example, if a set of dental remains are found at a crime scene, forensic odontologists can create a wax impression or plaster cast of the teeth. They can then compare this dental record to the dental records of potential missing persons. If there is a match, it can provide crucial evidence for identification.
