Currently, no study compares the learning and teaching outcomes following the use of one model to the other.

Examination scores of students attending or not attending the laboratory session were analyzed by a two\u2010sample <jats:italic>t<\/jats:italic>\u2010test.

Students who had better didactic performance in the course performed better in the final exam, irrespective of laboratory participation. Both students and faculty members preferred typodont to the pig mandibles in learning or teaching periodontal surgical concepts, but both felt gaining flap management and flap refection experience to be better with the pig mandible model without statistical significance (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.119 and <jats:italic>p<\/jats:italic>\u00a0=\u00a00.070, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Within the limitations of this study, we can conclude that laboratory sessions did not significantly improve student performance on the exam.
