Objective: Determining the prevalence of subgingival plaque bacteria before and after school-based education program in order to assess the effectiveness of oral health school-based instruction program on gingival condition.Methods: The research, which was conducted in April 2022, included (52 subjects as a test group and 44 subjects control group) from three Mosul City, Iraq, government schools who were between the ages of 13 and 18. The control group did not get any education, whereas the test group received fifteen minutes tutorial from a dentist and a hands-on session on oral inspection and tooth-brushing practices. The dental plaque Index was used at the first visit before the start of the education programs and at day 15. Bleeding for probing index was used to identify the inflamed site of the gingiva, and subgingival plaque samples were taken with paper points and transferred to 4 ml of enriched thioglycolate. IBM SPSS statistic, version 21 software was used to analyze the data using nonparametric methods. Mann-Whitney U test and Wilcoxon signed rank sum test were used in pairs to compare the data. Statistics were deemed significant if P 0.05. Results: The program of oral health had a significant impact on GI, PI, and bacterial counting records when test groups were compared at the beginning and end of the 15-day period. It also had a significant impact on PI and bacterial counting records when test groups were compared to control groups after the course, but had no significant impact on GI.Conclusion: The findings indicated that appropriate knowledge and habits about oral health were created in order to actively help and preserve these among school children.
