Periodontology – syllabus V course, X semester
Syllabus for state exam in periodontology

The department of Periodontology and oral disease performs practical and theoretical student training in two distinct subjects – Periodontology and oral disease and Oral pathology.
The educational course in Periodontology and oral disease spans over two academical years in four semesters with a total of 60 hours of lecturing and 135 hours practical training. The course covers the broad spectrum of prophylaxis, diagnostics, and treatment of periodontal and oral disease. The introductory section of the educational course involves one semester (the seventh semester) of pre-clinical training in periodontal instrumentation. The course continues in its clinical setting with practical training and ends at the end of the tenth semester with a final examination. Lecturers of the course are Assoc. prof. Georgi Tomov, dm and Assoc. prof. Elena Firkova, dm. Practical training in periodontal surgery is taught by Dr. Ivan Nachkov, specialist in maxillofacial surgery.
Students’ education in Periodontology and oral disease ends with the successful completion of 60 hours of state internship in the sixth year of education. The internship in periodontology is integrated with other essential dental subjects. The completion of the state internship concludes with treatment of a complex clinical case which is to be presented before the state examination.
The department of Periodontology and oral disease provides postgraduate specialty training in Periodontology as well. In 2020, four postgraduate students have successfully completed their training, while three others are still in the postgraduate course.
The department of Periodontology organizes an annual elective practical course in laser dental medicine for its undergraduate students, as well as many other elective practical courses, varying each academical year.

Since 2007, the subject of Oral pathology is included in the syllabus plan for undergraduate education in dental medicine. Since 2012, the department of Periodontology and oral disease harbors a separate section providing education to undergraduate students in Oral pathology. Head of the Oral pathology section is Georgi Tomov, dm. Teaching assistants in the section are Dr. Maria Mutafchieva and Dr. Nikolay Nikolov. The practical and theoretical training in oral pathology spans in a total of 30 hours (15 hours of lecture and 15 hours of practical training) during the sixth semester and ends with the successful completion of a final examination.
The section of Oral pathology is the only teaching entity at the Faculty of dental medicine that supports an online educational database providing lecture notes, tests and other materials available for students. The database is available in both English and Bulgarian –
