Methodology: 880 study subjects aged 13-15 yrs from 6 schools were randomly allocated to 6 groups, which were: health talk, health talk with charts and models, computer method, pamphlets, exhibition and control groups respectively. Their oral health knowledge was assessed by questionnaire and oral health status was assessed by plaque index (Silness and Loe) and gingival index (Loe and Silness) before and after oral health education. Results: Baseline mean oral health knowledge scores in groups I to VI were 7.54, 7.46, 7.58, 7.57,7.47 & 7.44 respectively; baseline mean plaque index scores in groups I to VI were 1.08, 1.02, 1.10, 1.08, 1.09 & 1.07 respectively and baseline mean gingival index scores in groups I to VI were 0.94, 0.87, 0.90, 0.95, 0.96 & 0.89 respectively. Mean oral health knowledge scores increased in groups I to VI by 2.87, 3.37, 4.34, 1.83, 1.88 and 0.06 respectively. Mean change in plaque index scores in groups I to VI were 0.10, -0.13, -0.20, 0.04, 0.14 & 0.22 respectively; and mean change in gingival index scores in groups I to VI 0.12, -0.11, -0.16, 0.05, 0.11 & 0.27 respectively.
