The objective of the study is to evaluate the impact of two pedagogical motivational approaches for plaque and gingival bleeding control among 135 students of local public schools in Santa Tereza, Brazil, in 1999 The motivational program consisted of different educational strategies offered to two distinct groups: Group A, who attended only one explanatory session about oral hygiene, and Group B, who attended a total of four pedagogical sessions. In order to evaluate the methodology applied, the visible plaque index (according to Ainamo & Bay, 1975) and gingival bleeding index (according to Löe and Silness, 1963) were calculated. A highly statistically significant reduction in the visible plaque index and gingival bleeding index was observed in both groups after the educational sessions (p<0.001). Moreover, a higher reduction in the gingival bleeding index and an even more accentuated decrease in the visible plaque index was found in group B when compared to group A (p<0.001). In conclusion, the motivational reinforcement in educational and preventive programs has a positive effect for the reduction and control of gingival bleeding and bacterial plaque.
