Abstract
Objective: The purpose of this study was to investigate the abrasive effect of tootpastes containing remineralization components.
Methods: The remineralization ingredients such as fluorides (T1: NaF 1,000 ppm F, T2: SMFP 1,000 ppm F), fluoride with potassium dihydrogen phosphate and dipotassium hydrogen phosphate (T3) were applied to the toothpastes having same compositions and same abrasivity. The hardness of dentin surface (VHN), dentin abrasivity and abrasion depth, cleaning power and physicochemical surface changes of the dentin surface (SEM / EDS) were evaluated in vitro with a control toothpaste without remineralization ingredients.
Results: All the Experimental toothpastes containing fluoride (T1-T3) significantly increased the micro-hardness of dentin specimen compared with the control toothpaste. The toothpaste containing two kinds of potassium orthophosphates with fluoride (T3) significantly increased hardness of dentin specimen compared with the fluoride containing toothpastes (T1-T2). Coexistence with fluorides and two kinds of potassium orthophosphates in toothpastes could reduce significantly dentin abrasivity and abrasion depth (p＜0.05). However, cleaning power among toothpastes having different abrasivity from the dentin remineralization effect was not significantly different (p＞0.05).
Conclusion: Dentin abrasion by brushing could be reduced by using fluoride, monopotassium phosphate and dipotassium phosphate in toothpaste without changing of cleaning power.
