Question

forensic odontology would not be useful for _____.
identification of individuals buried in a mass grave discovered after a war
identification of a perpetrator who left behind his car keys
identification of victims of the 9/11 attacks on the twin towers
identification of victims found after a huge house fire

Explanation:

Forensic odontology uses dental records and characteristics for identification. In cases of mass - graves, 9/11 attacks, and house fires, dental remains can be used for identification. However, car keys left behind by a perpetrator have no connection to dental characteristics, so forensic odontology is not useful for this.

Answer:

Identification of a perpetrator who left behind his car keys
