详细描述
Design:
The trial was designed as a cross-over clustered randomized control trial (each group was a cluster), so that each group acted as their own control for their knowledge's retention and perception.
Setting and consent: College of Dentistry, Prince Sattam Bin Abdulaziz University/Alkharj/ Saudi Arabia. Written consents were obtained from students before commencing the trail.
Participants : The cohort of the trial included the whole fourth-year undergraduate class (34 undergraduate dental students) in order to eliminate selection bias. Participants in this study had no prior orthodontic teaching, hence, no bias associated with increased knowledge in any orthodontic field was anticipated.
Randomization: Students were allocated to one of two even groups (G1 or G2) using computer generated randomization. each group (G1 and G2) consisted of 17 male students with a mean age of (23.27 years ± 0.86).
