Final answer:
A personal dentist can offer expert testimony and provide dental facts in court, especially in cases of personal injury due to malpractice or to present dental identity studies of unknown victims.
Step-by-step explanation:
A personal dentist is legally permitted to offer expert testimony in courts of law. This expert witness can provide specialized knowledge to the court, including dental facts about personal injury potentially due to malpractice, and can also submit the results of a dental identity study of an unknown victim. However, the role of the dentist does not extend to convicting individuals or identifying perpetrators, as that is beyond the scope of their expertise and responsibility, which is to help the court with their specialized knowledge and technical findings.
