Design outcomes

Primary

Measure	Time frame
The main outcome of this study will be to evaluate supragingival inflammatory parameters (Gingival Index) in patients diagnosed with gingivitis who will use toothbrushes with heads of different sizes.	—

Secondary

Measure	Time frame
To assess the presence of gingival fissures at different experimental periods (1 week, 4 weeks, and 6 weeks).;To evaluate the wear of the bristles of the brushes used in the different experimental groups.	—
