If a foreign dentist from India got accepted to a U.S. Perio Program, would they be able to practice Perio in the U.S., once they pass the Perio Exam?

Once they have the perio certification, would they need to re-do their DDS/DMD in U.S. to work in private practice doing Perio, or is the Perio degree itself, enough?
