Incidence Assessment of Gingival Fissures Associated with the Use of Manual and Electric Toothbrushes

Gingival fissures (GF) have been suggested as risk indicators for clinical attachment loss (CAL) and gingival recession, especially in free surfaces and in patients with low plaque scores. The major factors related to the GF occurrence are high daily brushing frequencies, excessive force to brush, malpositioned teeth, use of abrasive dentifrices, and stiffness of the toothbrushes bristles. Thus, in order to better understand the pathogenesis and progression of GF, this study aim to evaluate the incidence of GF in young adults using manual and electric soft toothbrushes, in a cross-over randomized clinical trial along 2 months.
