Comparative study investigating abrasive effects of 12 commercially availabletoothpastes on enamel, in Iran

ABSTRACT

An ideal toothpaste should have most plaque removal efficacy with at least abrasivity. The aim of this study was to evaluate enamel abrasion induced by 12 toothpaste types including Darogar 3, Nasim, Crest 7, Crest sensitivity, whitening signal, sehat, pooneh 3 color, paveh, whitening pooneh, crest 3D white, sensodine original and pooneh sensitivity. This was an in vitro experimental study. Dental samples collected after cutting were embedded in acrylic blocks, and the enamel surface polished to be smooth. The samples were divided into six groups of twelve. The initial surface profile was measured with the profilometry device and for brushing; the samples were located in VScross brushing machine. After washing and drying the samples, the secondary surface profile was measured with the profilometry device again. The value difference before and after brushing shows abrasion of the toothpaste on single micron. Data were analyzed by means of ONE WAY ANOVA. There was no significant difference in abrasivity among different toothpastes. The highest rate and the lowest rate of abration were observed in crest sentifivity and pooneh sensivity, respectively. The abration sensitivity pooneh; rate of other toothpastes were between these two rates. According to the results it has been revealed that there were no differences among enamel abrasion of common Iranian toothpastes
