A survey of problems related to stress encountered by 1,255 Canadian dental students was conducted. Substantial experience with problems was reported infrequently, although most students were affected negatively by at least one problem. Most difficulties concerned students' doubts about harnessing their efforts and abilities to master large amounts of material, which, of necessity, reduced their opportunity to pursue other interests. Few demographic features predicted the level of students' problems, although there was an indication that those who perceived themselves above average academically reported fewer problems.
