Introduction and objective:
The main aim of the research was to estimate the need for prosthetic treatment among students of three Bialystok universities and to analyse the factors that may influence this need.

Material and Methods:
The research involved a group of 380 students attending three different Bialystok universities: Medical University of Bialystok, University of Bialystok and Bialystok University of Technology. The questionnaire comprised of 9 questions indicating such problems as: missing teeth, reasons for lack of the teeth, kind of treatment used or reasons why it was not administered, was used to collect the data. A Chi2 test was used to analyse relationships between investigated factors.

Results:
Missing teeth were reported in 109 of the surveyed (28.7%). Orthodontic reasons and caries as a second reason were the most common causes for missing teeth occurrence. 19 students (17.4%) with missing teeth had prosthetic appliances. Those who had not undergone prosthetic treatment gave orthodontic reasons (21.4%) as the cause or subjective lack of need for treatment (18.4%). The occurrence of missing teeth did not statistically differ between universities.

Conclusions:
The research showed a quantity drop in missing teeth occurrences when compared to research by other authors. Although it was observed that the number of missing teeth is decreasing, there are still too few people who fill them properly, which may suggest insufficient awareness of tooth loss consequences
