[In vitro evaluation of the mechanical effects of sensitive toothpastes of the Swiss market].
"Sensitive pastes" are advertised for use by patients suffering from dentin hypersensitivity. Their market share is growing. Their potential of adverse mechanical side effects on dentin are consequently of concern. The aim of this study was to assess the cleaning efficiency, the relative dentin abrasion and the surface roughness induced by ten sensitive toothpastes of the Swiss market. Cleaning efficiency was assessed planimetrically, the relative dentin abrasion was measured using a radio tracer method and the surface roughness was established using a surface scanning method. Four out of the ten tested sensitive toothpastes produced only low abrasion and surface roughening on dentin, and are consequently suitable for the use by patients with dentin hypersensitivity. The remaining six pastes are too aggressive to warrant unlimited use on exposed dentin surfaces. The pain relieving effect of active ingredients of the toothpastes was not assessed.
