Background & Aim: Tooth brushing along with a toothpaste is the most frequent and important method in managing a healthy oral hygiene. However, using such products also has its side-effects and shortcomings. Considering the large range of toothpastes available and the insufficiency of proper researches in this area in Iran, this study was designed to evaluate the abrasiveness of a toothpaste for sensitive teeth and a whitening one with two similar Iranian brands.

Materials & Methods: This was an invitro experimental study. Four groups of enamel samples consisting of each 6 specimens were prepared and embedded in acrylic blocks. The initial surface profile for each specimen was calculated using a profilometer. The samples undertook the wear phase in a V8 Cross Brushing machine using toothbrushes and a toothpaste solution. The samples were then dried and the surface profile was again calculated. The variation of the first and second profilometer calculations demonstrate the amount of wear for each specimen. Data was analyzed using the SPSS program by means of One way ANOVA and Repeated Measure ANOVA tests.

Results: The amount of wear recorded for the 4 experimental groups was significantly different (p=0.039). However, the two by two comparision tests showed that the Iranian brands did not appear to have a significant difference with their foreign counterparts (p>0.05). The only difference was apperant between the two Iranian brand groups.

Conclusion: According to the present study, it seems that there is no significant difference in the abrasive properties of the Iranian and foreign made toothpastes. However, similar researches considering different effects of toothpastes and especially in more clinical conditions and by utilizing different measurement methods appears to be necessary in Iran.

Keywords: Toothpaste, dental enamel, abrasion, profilometery.
