Objectives:
Eroded teeth are more susceptible to toothbrushing wear than sound teeth. We tested the hypothesis that fluoride and abrasivity of dentifrices can interact, modulating the development of erosive-abrasive lesions.
Methods:
Human enamel and root dentin specimens were submitted to cycles of demineralization, remineralization and toothbrushing using six dentifrices formulated with three different abrasivity levels: low (L), medium (M) and high (H); with (+F) and without (-F) fluoride. Surface loss was quantified by optical profilometry and compared among groups (alpha=0.05).
Results:
In dentin, it was ranked: L
Conclusions:
Both fluoride and abrasivity were important modulators of enamel surface loss, while abrasivity had a higher impact than fluoride on dentin.
