초록
The aim of this study was to evaluate the abrasive effect and cleaning power of toothpaste containing tetrasodium pyrophosphate and cellulose. The relative dentin abrasivity, cleaning power by modified Stookey method, dentin abrasivity of brushing after Cola treatment and consumer survey were investigated with control toothpaste containing dental type silica as an abrasive. The results obtained were as follows: 1. Experimental toothpaste hardly influenced dentin abrasivity, but control toothpaste had an effect on dentin abrasivity significantly (p＜0.05). 2. There was no significant difference in cleaning power between experimental and control toothpaste (p＞0.05). 3. Experimental toothpaste hardly influenced dentin abrasivity, despite 100 or 1,000 times of brushing after Cola treatment, but control toothpaste showed a big increase in dentin abrasivity as the number of brushing has been increased (p＜0.05). 4. According to the consumer survey results, there was no difference between control and experimental toothpaste in the satisfaction rate of refreshing sensation, the satisfaction rate of the lasting effect of refreshing sensation and the overall satisfaction rate of the toothpaste (p＞0.05). These results showed a possibility to make abrasive free toothpaste having cleaning power without dentin abrasivity.
