Gingival abrasions resulting from brushing are reversible epithelial lesions, presenting a superficial or exposed tissue. These lesions have been considered subrogated outcome of gingival recession, although the mechanisms by which gingival abrasion result in apical migration of the junctional epithelium, bone loss, gum recession and consequently, have not yet been known. The aim of this study was to evaluate the effect of the type of filament of soft bristle brushes (round and tapered), and the presence dentifrice. Gingival abrasion is the primary endpoint and secondary is the ability to remove plaque. The experimental design was crossed. Thirty-nine patients with gingival health abstained from oral hygiene for 72 hours. The following contralateral quadrants were randomized to be brushed with a toothbrush rounded or tapered filaments, each quadrant for 30 seconds, totaling to two minutes. In the first period was used fluoridated toothpaste, brushing the second period was performed with water only. "Washout" of a week between the periods will be held. Evaluation of Stained Plaque and gingival abrasion were performed before and after brushing. The results of this study demonstrated that both bristle brushes soft, rounded or conical, were effective in removing plaque (p <0.05), and promoted significantly more gingival abrasion injuries comparing the baseline period and after brushing (p <0.05), but no statistically significant difference between the brushes evaluated. The use of the dentifrice contributed to greater removal of plaque (p> 0.05) and increased number of injuries abrasion gum (p <0.05), most of the sites evaluated. The rounded brush filament showed higher levels of gingival abrasion injury, but was more effective at removing plaque stained. Both brushes used in the study were effective and safe.
