Abstract
Objective: The purpose of this study is to investigate anti-calculus formation effect through abrasivity of toothpaste containing ground calcium carbonate (here after GCC) and hydrous silicon dioxide (here after HSD).
Methods: Toothpaste containing only dental silica and toothpaste containing dental silica, GCC and HSD were used as control group and experimental group, respectively. Bovine teeth were cut into 3 mm diameter and 16 specimens were made for each group. Surface of them was polished and then measured the mass. The 2:1 ratio suspension of distilled water and detergent was filled in the brushing machine and 20,000 toothbrushing was performed. The mass was measured before and after the experiment, and the abrasivity of each block was calculated.
Results: The average abravisity of the control group was 0.5871±0.1 and the average abravisity of the experimental group was 0.6114±0.06, which was higher than that of the control group. There was a significant difference in the comparison between before and after brushing (p＜0.05), and there was no significant difference in the comparison between the group (p＞0.05).
Conclusion: Overall, the experimental group was found to have higher abrasivity than the control group, but there was no significant difference.
