We just learned about how scientists can use Forensic Botany to figure out what kind of plants were around during a crime.
Another part of forensic science is Forensic Dentistry.
Sometimes after a crime has been committed, scientists will look at teeth to figure out what really happened.
If there was a fight between two people and one person bit the other person, they can look at the bite mark and try to match it up to the other person's teeth!
There also might be a skeleton that was found from a long time ago, and people aren't sure who it was.
If that person ever went to the dentist and had molds made of their teeth or x-rays of them, they can try to match it up and see who it was.
The teeth can also tell a scientist how old a person was when they died.
This can even be helpful for people that died hundreds of years ago, when people are digging out ancient pyramids, castles or finding cavemen!
