Aristotle University of Thessaloniki

Department of Operative Dentistry

  • The Department of Operative Dentistry was established in 1959 (N.Δ. 3974/1959 ΦΕΚ188/7-9-59 τ.Α΄) and belongs to the Section of Pathology and Therapeutics of Dental Tissues. The main objective of the Department of Operative Dentistry is to educate dental students on the topic of Operative Dentistry, which includes basic knowledge in diagnosis, prevention, treatment and rehabilitation of caries and other diseases of hard dental tissues. Additionally, the Department is offering a three year postgraduate course in Operative Dentistry and Aesthetic Dentistry, which leads to Master of Sciene (MSc) degree.

    The in vitro studies are carried out in the laboratories of the Aristotle University of Thessaloniki, while the clinical trials are conducted mainly in the undergraduate and postgraduate clinics of the Department of Operative Dentistry of A.U.Th. There is also a wide collaboration with research laboratories of other national and international universities.

    Post-educational Activities Since 2019 the Department of Operative Dentistry of A.U.Th organize anually a Programme of Continuous Education entitled: "Education in clinical skills in Restorative and Aesthetic Dentistry", which yields to 7.5 ECTS units. Since 2017 the Department of Operative Dentistry of A.U.Th collabotate with Department of Operative Dentistry and Periodontology of the University of Aachen (RWTH) and Hellenic Academy for Laser Dentistry (H.A.L.D) and organize together various educational and research activities focusing on the area of Lasers in Dentistry. On this context they organize an annual Mastership / Fellowship Course which regards training in use of all laser wavelengths, as well as annually a seminar for Laser Safety Officer (L.S.O) certificate.
