Efficacy of peer mentoring versus dentist-led instruction for knowledge enhancement about oral health: A Clinical Trial

Background & Aim: Oral hygiene instructions are routinely provided at schools by health mentors and dentists. Recently, oral hygiene instruction by peers has gained popularity. This study aimed to compare the effect of oral hygiene instruction by dentists and peers on the level of knowledge of twelve-year old children. Methods and Materials: In this interventional randomized clinical trial, four schools were randomly selected. The level of oral health knowledge of students was assessed by a pretest. Oral hygiene instructions were then provided by dentists in control schools and by peer mentors in test schools. Knowledge of students about oral health was evaluated in the two groups immediately and after 1 month post instruction.

Results: Oral hygiene instruction enhanced the overall knowledge of students about oral health immediately and at one month after the instruction compared with baseline in both groups (P
