Aim: The aim of this study was to assess senior dental students’ acquisition of knowledge after 3 months following a reminder lecture.

Materials and Methods: A 1 h lecture including a slide presentation was prepared according to the Guidelines of International Association of Dental Traumatology (IADT). The participants were asked to fill-out a questionnaire of 31 questions before (T0), after (T1) and 3 months (T2) after the lecture and were given 15 min for the completion of each questionnaire. Statistical significance level was set at P<0.05.

Results: The average percentage of correct answers was higher after lecture than before (P<0.05) and there was some retention of knowledge after three months (P<0.05). The information was more retentive when delivered in the second part of the lecture (P<0.05) and for the students who encountered no trauma cases previously, whereas there was no difference between genders.

Conclusions: One-hour reminder lecture on trauma just before graduation is beneficial for dental students. Provision of students with take home messages in the last part of the lecture can be recommended as information seems more retentive when delivered at this stage. The students who encountered no trauma cases previously may benefit more from a 1 h reminder lecture.
