The Department shall require that each applicant for a license to practice dentistry shall:
(e) Present satisfactory evidence that the applicant has passed the integrated National Board Dental Examination administered by the Joint Commission on National Dental Examinations and has successfully completed an examination conducted by one of the following regional testing services: the Central Regional Dental Testing Service, Inc. (CRDTS), the Southern Regional Testing Agency, Inc. (SRTA), the Western Regional Examining Board (WREB), the Commission on Dental Competency Assessments (CDCA) , or the Council of Interstate Testing Agencies (CITA). For purposes of this Section, successful completion shall mean that the applicant has achieved a minimum passing score as determined by the applicable regional testing service. The Secretary may suspend a regional testing service under this subsection (e) if, after proper notice and hearing, it is established that (i) the integrity of the examination has been breached so as to make future test results unreliable or (ii) the test is fundamentally deficient in testing clinical competency. In determining professional capacity under this Section, any individual who has not been actively engaged in the practice of dentistry, has not been a dental student, or has not been engaged in a formal program of dental education during the 5 years immediately preceding the filing of an application may be required to complete such additional testing, training, or remedial education as the Board may deem necessary in order to establish the applicant's present capacity to practice dentistry with reasonable judgment, skill, and safety.
