Doctor of Dental Surgery


D.D.S. is a six-year program which consists of a competency-based educational plan with emphasis on prevention caring, so that graduate students, besides sufficient and comprehensive knowledge in up-to-date dentistry sciences, have the skills for visiting patients and treating different kinds of oral and dental diseases. In this program, students pass basic sciences in two years and then enter the clinic for 4 years in order to pass courses in all dentistry departments and learn the diagnosis of different kinds of diseases in each department. As a result of working with numerous patients, students will become highly skilled in their clinical stage.


Doctor of Dental Surgery (D.D.S.)

Students of the D.D.S. program pass pre-clinic courses in the fifth semester in laboratories with different kinds of moulages and educational models that are simulated with real clinical conditions and patients. After acquiring the requirements, eligible students enter the clinics, and visit and treat patients. In the clinical stage, students (in small groups) enter the clinic and treat patients. Students of Community Dentistry program enter the field and start the process of screening patients in the society.


In the twelfth semester, students who have acquired enough skills as interns or pre-doctoral students enter the main clinic and visit patients in a similar fashion to practices in a private office under the supervision of proficient professors. In the main clinic, students, besides making medical files for the main treatment program, treat all kinds of dental problems of patients. At the end of this semester, students test their scientific and practical capabilities by taking a final exam.


Language of Instruction

D.D.S. classes, in their early sessions, are held in English, but the rest of the D.D.S. program will be held in Persian.


The language of instruction at TUMS for international students is English both at the undergraduate and graduate levels. However, since some of the majors and programs at the undergraduate level require students to have interaction with patients who speak Persian, learning Persian could be obligatory for the students of those majors. These students are often M.D. and D.D.S. students but it is the Office of Admissions which specifies for which programs Persian or remedial English courses are obligatory or optional.


The Language Academy at TUMS International College immediately took charge of teaching Persian to TUMS international students in the first step and stopped outsourcing for this service. Regarding teaching English to TUMS students, staff and faculty members, the Academy undertook the instruction for some groups but still outsourced it for others, with a more thorough supervision on them. It is, however, going to take charge of the whole instruction by mid-2016 in a number of phases.



All your D.D.S. and Persian language learning classes will be held in Tehran, the capital of Iran.


Program Duration

The D.D.S. program lasts at least 5-6 years.


Program Overview

In the first year, students pass some general and basic sciences subjects, both theoretical and practical, in classes and laboratories. In the second year, students pass specialized subjects and the remaining general subjects, both theoretically and practically. Once the third year starts, that is in the fifth semester, students enter pre-clinic courses and learn the models and moulages in laboratories. The most important change at this stage is that from the third year, they enter the clinic and start treating patients.


The fourth year includes the subjects of Dental Public Health, Oral Surgery, Oral Diseases and Diagnosis, Oral Radiology, Oral Pathology, and Operative Dentistry, and students pass the subjects of Orthodontics, Periodontics, Pediatric Dentistry, Traumatology, Advanced Operative Dentistry, Advanced Endodontics, Advanced Oral Surgery, and Research Methodology in their fifth year of studies.


In the eleventh semester, students pass the last practical subjects in the form of complementary courses for improving their skills and undertake the treatment of difficult cases, and prepare in order to enter the internship and pre-doctoral courses. In the twelfth semester, eligible students reach the main clinical course and enter the main clinic. In this simulated clinic, which is similar to a real dentist’s office, students of pre-doctoral course work on all types of treatments necessary for all kinds of patients.


At the end of this course, by participating in a final exam, the students’ theoretical knowledge will be evaluated. Afterwards, they get ready for their thesis defense sessions. In the fourth year, they can carry out their thesis with the aid of a professor, and defend their thesis at the end of the twelfth semester.
