The purpose of this blind randomized clinical trial is to evaluate different frequencies in self-mechanical control of plaque in individuals with historic of periodontitis and in periodic and preventive maintenance in order to assess which frequencies are compatible with maintaining gingival health.
Thirty nine subjects with at most 5% of the sites for GI= 2 (gingival health) will be randomized into three groups with different frequencies in self-mechanical control of plaque: Group 12 hours, 24 hours and 48 hours. The exams of plaque index, gingival index, probing depth, bleeding on probing, clinical attachment level and gingival crevicular fluid will be performed at baseline, 15, 30, 60 and 90 days.

RECRUITINGChanges from baseline gingival index at 30, 60 and 90 days.
Assess how different frequencies of self-performed mechanical control of plaque interfere in gingival status.
Time frame: 30,60 and 90 days.
Changes from baseline plaque level at 30,60 and 90 days.
* Assess how different frequencies of self-performed mechanical control of plaque interfere in the accumulation of supragingival biofilm. * Correlate changes in plaque levels with changes in gingival index.
Time frame: 30,60 and 90 days.
Changes from volume of gingival fluid at 30,60 and 90 days.
* Assess how different frequencies of self-performed mechanical control of plaque interfere in the volume of gingival fluid. * Correlate volume of gingival fluid with GI scores and bleeding on probing scores.
Time frame: 30,60 and 90 days.
