Protection by Total Care Enamel Guard
LISTERINE® Total Care Enamel Guard provides effective enamel re-hardening for effective protection
In a study to determine re-mineralisation potential and resistance to acid challenge of human enamel samples, LISTERINE® Total Care Enamel Guard showed enamel re-hardening comparable to Sensodyne Pronamel after 20 days and after acid challenge in vitro.1 Differences in microhardness between LISTERINE® Total Care Enamel Guard with 225 ppm fluoride and Sensodyne ProNamel with 450 ppm fluoride were not significant after 20 days or at any time point (p>0.05).1
Increase in microhardness (vickers hardness number; VHN) after 20 days1
- After a 2-hour acid challenge, LISTERINE® Total Care Enamel Guard achieved enamel microhardness comparable to Sensodyne ProNamel in vitro (p=0.206)1
