Abstract
This study aimed to assess the proportions of complicated endodontic cases treated by undergraduate dental students in a University clinic now and in the past. Data were obtained from the electronic records and previous publications from the Faculty of Dentistry, University of Oslo, Norway. The operators were dental undergraduate students in their final 2 years of training. Proportions of tooth types, diagnosis, and retreatments were studied. The amount of endodontically treated molars increased from 18% in 1971% to 44% in 2019. The number of teeth with preoperative apical periodontitis increased from 31% to 46%, and retreatments from 9% to 15%. The changes were highly significant, with the greatest change occurring from 1984 to 2009. Undergraduate students are exposed to more complicated teeth now than 50 years ago.
