Preclinics of Conservative Dentistry is a part of the educational program of IV, V and VI semester.

EDUCATIONAL FORMS AND METHODS USED IN THE COURSE: lectures, practical classes, seminars, tests, discussions, slides, multimedia presentations, diagrams, models, tests.

Conservative dentistry course gives the opportunity to acquire knowledge and competences in operative dentistry and endodontics which are necessary for organizing and carrying out a successful dental help.
CONSERVATIVE DENTISTRY IS A DISCIPLINE that includes: surgical and restorative treatment of carious and non-carious lesions of hard dental tissues in the sense of surgical dentistry, endodontics and dental physiotherapy. 
Preclinics of Conservative Dentistry is the first stage (from IV to VI semester) of the education in the field of operative dentistry and endodontics. In this stage students earn theoretical and practical knowledge about the instruments, principles of cavity preparation, obturation with different filling materials, endodontic access preparation, endodontic treatment procedures (shaping, cleaning, irrigation, obturation of the root canals) and also about the restorative procedures of endodontically treated teeth.
The training is carried out through lectures with a duration of 2 academic hours /2 x 45 minutes/, seminars with a duration of up to 1 academic hour, practical exercises on a phantom with a duration of 4 academic hours per week. 
Successful graduates take semester exams.

The aim of the educational program is to introduce students to the basics of cavity preparartion, medication and obturation, to the field of endodontics (access, medication, preparation and obtiration of the root canals). 
The acquired competencies enable the organization of dental help in accordance with European standards for medical service.


  • isolation of the operative field;
  • teaching in preparation all groups of cavity preparations according to the basic principles;
  • theory education in medication of the dentine wound and pharmacodynamics;
  • achieving new skills in obturation of the cavities with different materials and methods;
  • Preparation of the students about the tooth anatomy, endodontic treatment and restoration of endodontically treated teeth.

After the preclinical course the students should be able to know and prepare the basic cavity configurations and correct medication of the dentine wound. They should manage successfully the different obturation methods.
Regarding endodontics, the students should plan correctly the endodontic access, prepare and obturate properly root canals and should plan a successful approach for restoration of the endodontically treated teeth.
