The influence of brushing with theobromine and sodium monofluorophosphate toothpaste on enamel surface resistance to roughness after demineralization

Abstract

Herein, the influence of brushing with theobromine and sodium monofluorophosphate toothpaste on enamel surface roughness resistance after demineralization was determined. Overall, 21 human premolar enamel specimens were ground, polished, divided into three groups, and brushed for 5 minutes each with theobromine toothpaste, with sodium monofluorophosphate (MFP) toothpaste, or without toothpaste (control group). Next, specimens from the three groups were immersed in 20 ml of Coca-Cola® for 75 minutes. Surface roughness was measured before brushing, after brushing, and after immersion. Repeated ANOVA tests in the control group showed a non-significant (p > 0.05) increase in roughness after brushing and a significant increase (p < 0.05) in roughness after immersion. The theobromine group showed a significant (p < 0.05) increase in roughness after brushing and non-significant (p > 0.05) increase after immersion, and the MFP group showed a significant (p < 0.05) increase in roughness after brushing and after immersion. One-way ANOVA test showed that the theobromine group had the lowest increase in roughness (p > 0.05) after immersion, but it was not statistically significant compared to brushing using MFP. Therefore, brushing with theobromine toothpaste maintains enamel surface roughness after demineralization in Coca-Cola® and is slightly better than brushing with MFP toothpaste.
