Objective: To evalúate the presence of supragingival bacterial plaque and Porphyromona gingivalis before and after the implementation of an educational program for oral hygiene. Methods: 30 scholars were enrolled for 3 months, in order to strenghten their oral hygiene technique and obtain a gingival sulcus bacterial plaque sample monthly. Results: Porphyromona gingivalis was present in 100% of cases. After 30 days of intervention, oral hygiene reduction in O'Leary rate was 21.15%) and bacteria colony forming units in 21.51%o. After 60 days, O'Leary Índex declined in 29.45%> and bacteria colony forming units in 16.12%o. Conclusions: The implementation of an oral hygiene program has a direct impact in the composition of the gingival sulcus bacterial plaque and the decrease of Porphyromona gingivalis colony forming units, mainly at 30 days intervention
