Admission Requirements

Meet the eligibility requirements established by the Faculty of Graduate Studies, Graduate Periodontology Program Admission Subcommittee, and the Medical Sciences Graduate Program Committee.

Selection Process

Applications for the PhD in Medical Sciences (Periodontology) will be reviewed by all full- and part-time faculty members of the Periodontology Graduate program. Suitable candidates will be invited to interview.

The interview committee may include full- and part-time Periodontology Academic faculty, a Periodontology Graduate student, Affiliate Academic staff and a representative from the School of Dentistry Graduate Studies Committee.

Interviewed candidates (also including the MSc interviewed applicants) will be ranked and offers of admission made. If determined eligible for admission, the candidate will be offered a second interview with the Department of Dentistry Graduate Studies subcommittee. This subcommittee has to also support admission.

Admission to the PhD in Medical Sciences (Periodontology) is dependent upon the recommendation of the Graduate Periodontology Program Admission Subcommittee, Department of Dentistry Graduate Studies Subcommittee and the Medical Sciences Graduate Program Committee. The FGSR makes the final decision.

Tuition & Fees

Candidates should be prepared to support themselves for the duration of their selected program. Applications for funding from scholarships and studentships may be obtained through a competitive basis and are encouraged prior to or during the tenure of the program.

More courses may be taken over and above what is required for the program based on requirements set by the supervising committee. Any courses being taken over and above what is required for the program should be registered for with the assistance of the Graduate Program Administrator. 

The maximum time permitted to complete the program as set by the Faculty of Graduate Studies and Research is six years. Students are required to reside in Edmonton for the entirety of their Clinical training. Residency for the remainder of the program is dependent on discussions with your Supervisor, requirements of research, and course offerings. Oral examinations may be required to be in-person. 


Students are required to complete research, usually within the established research focus of the program, and to complete a paper format thesis. Students should have their research results ready to submit to peer reviewed journals for publication. It is anticipated that all student research projects will result in publication. Students may also have an opportunity to present their research results at an international scientific meeting prior to completion of the program.

PhD students begin the clinical portion of the program after they have completed their Candidacy examination. Successful completion of the Candidacy examination is required within three years of  the start date of the program. 

Clinical Assessments

Oral assessments are completed during the clinical training. Full-time academic staff will assess diagnosis and treatment planning skills. Feedback from this assessment will serve to identify weak areas in the student's progress that will permit the development of specific improvement objectives before the next annual assessment. Failure to overcome the limitations will require the student to extend their program or may imply a failing grade in the clinical course(s).

If offered admission to the program, an Education and Research license is required from Alberta Dental Association and College (ADA&C). This documentation is due by August 1 prior to starting the program in the fall term. Candidates who already possess a full license from the ADA&C do not need to obtain additional licensure.
