The board shall not restore such license to good standing until it shall receive competent evidence, from one or more physicians specializing in psychiatry, designated by the board, of the absence or control of the condition which caused its action and until it is satisfied that with due regard to the public interest the licensee's right to practice may be safely reinstated.
Before reinstating such a person, the board may require the person to pass an oral or written examination, or both, to determine his present fitness to resume his practice.
