Effect of Different Toothpaste On remineralization Of Initial Enamel Lesions

Methods: Sixty enamel specimens were prepared from exracted human molars. The specimens were randomly assigned to five study groups and one control group of 10 specimens per group: Groups (1) Novamin (calcium-sodium-phosphosilicate); (2) Recaldent (casein phosphopeptide-amorphous calcium phosphate); (3) Enzycal (enzymatic toothpaste) (4) Pro-Argin (toothpaste containing arginine); (5) Sensodyne (fluoride toothpaste) and (6) control group-unexposed to any product.All specimens were exposed to de-remineralizing solutions for one week except control group. After pH-cycling,  the remineralizing agents were applied to the samples with tooth brush simulator two minutes two times in one day for five days.The samples were analyzed by Scanning Electron Microscope, (SEM) and energy-dispersive X-ray spectroscopy analysis (EDX). The data were analyzed One-way ANOVA and two sample T tests (p<0,05).

Results: The EDX analysis showed that the amounts of Ca, P, Si and Na of the Group 4 increased more than other groups (p<0.05).

Conclusions: Pro-Argin toothpaste has the potential to remineralize enamel, this effect might be important for initial enamel lesions.
