The aim of this investigation was to compare the potential remineralization effect of topical NovaMin and Sodium Fluoride gel on caries like lesion in permanent teeth.
Methods:
A total of 60 sound human freshly extracted teeth were subjected to a PH-cycling protocol. Specimens were randomly assigned to one of the two treatment groups with NovaMin contained dentifrice applied to Group while group 2 received a dentifrice containing 1.1% Neutral Sodium Fluoride. Pasts were applied five times after the samples received a demineralization from an earlier cariogenic challenge. Specimens were then evaluated by a Surface Micro Hardness test (SMH,25G,5s). Post-treatment SMH measurements were conducted and independent T-test was employed for statistical analysis.
Results:
Mean post lesion SMH values were 221.99±26.27 and 224.50±28.64 for the first and second groups, respectively. Post treatment SMH values were 232.52±24.34 for NovaMin and 232.03 ±24.46 for the fluoride group. Independent T test showed a significant difference between the two different treatment protocols (p=0.007).
Conclusions:
NovaMin dentifrice appears to have a greater effect on re-mineralization of carious-like lesions when compared to that of fluoride containing dentifrice in permanent teeth.
