Abstract

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.

함수 피로인산나트륨과 셀룰로오스를 배합한 세치제에 대하여 비교치아마모도평가, 세정력평가, 산성음료 처리 후 치아마모도 평가 및 설문조사를 실시한 결과, 다음과 같은 결론을 얻었다. 1. 비교치아마모도 평가결과 값은 실험세치제에서는 $0.49{\pm}0.89$, 대조세치제에서는 $49.50{\pm}4.68$로 나타났으며(p<0.05), 이는 실험세치제가 치아 상아질을 거의 마모시키지 않는다는 것을 의미한다. 2. 세정력평가에서는 실험세치제와 대조세치제 간의 통계적 유의성은 나타나지 않았다(p>0.05). 3. 산성음료 처리 후 치아마모도 평가는 실험세치제가 산성음료 처리 후 칫솔질 후에도 유의성 있게 대조세치제에 비하여 치아를 거의 마모시키지 않음을 확인하였다(p<0.05). 4. 설문 조사결과, 상쾌함, 상쾌함의 지속성 및 전반적 만족도는 실험세치제와 대조세치제가 비슷한 것으로 평가되었다(p>0.05). 함수 피로인산나트륨과 셀룰로오스를 배합한 세치제는 세정력은 가지면서 산성음료 섭취 후 칫솔질 함에도 치아의 마모가 거의 없는 세치제 개발의 가능성을 보여주었다.
