To acquire a dental radiology license, the candidate must attain a degree from an accepted dental institution and successfully pass a practical and written exam, according to the U.S. Bureau of Labor Statistics. Additional requirements can vary from state to state, and dental radiologists need schooling beyond traditional dental school.
An extra two to four years of schooling is required to become a licensed dental or oral and maxillofacial radiologist, notes the BLS. There is also a chance the candidate must pass a special state certification exam. Some states also require dental radiologists to complete a special postgraduate residency term, which can take as many as two years to complete.
Before being accepted into dental school, a person usually must first attain a bachelor's degree, according to the BLS. There are also certain classes candidates might have to pass, such as chemistry and biology. Future dental radiologists are often required to pass the Dental Acceptance Test, which dental schools use along with the applicant's grade point average and recommendations to determine whether to extend an invitation to the applicant.
While preparing for licensure in dental school, students often study periodontology, anesthesia, anatomy and radiology, notes the BLS. Becoming a dental radiologist might also require a residency in a dental radiology program, which often takes one to two years.
