ObjectiveTo evaluate the difference in peer-assisted learning (PAL) and expert-assisted learning (EAL) sessions for selected topics of orthodontics, conducted by either a peer or faculty member, respectively as measured by their test scores.Study DesignExperimental study. Place and Duration of Study: Department of Orthodontics, Altamash Institute of Dental Medicine (AIDM) Karachi, Pakistan, from October 2019 to March 2020.     Methodology: The study was carried out with the final year undergraduate dental students in the subject of orthodontics, selected by using non-probability sampling method. Selected students were given an introductory lecture on PAL approach at the start of the study. Two PAL sessions were conducted in smaller groups with all students utilised as an adjunct to traditional large group lectures; and at the end assessment was conducted comprising of multiple choice questions (MCQ). For the consecutive four weeks, same students went through traditional EAL, followed by similar type of assessment. Their test scores were compared for significance, set at p <0.05.ResultsA total of six sessions were conducted, two faculty members (professors of orthodontics) conducted two sessions each, and subsequent two sessions were conducted by employing PAL approach by students (earlier trained by the faculty). The mean differences in the scores of students was compared between faculty teaching and PAL-related teaching. It was observed that the EAL group significantly performed better than PAL group (p<0.05).ConclusionIn terms of test scores, academic performance and overall learning in PAL sessions was not higher than EAL group. Nonetheless, PAL can be utilised as an important supplement to synchronous teaching tele-presence by faculty as being practised during current pandemic situation in many medical and dental institutes.
