Abstract
This study aimed to evaluate the capacity of Calcium Sodium
Phosphosilicate (Novamin) on remineralization of initial Enamel lesions. Materials
and Methods: Enamel surfaces of 90 freshly extracted human premolars were
subjected to ESEM analysis & Microhardness measurements. Initial enamel lesions
were produced in all premolars which were divided, according to the remineralizing
regimens, into three equal groups (n=30): Group I: received deionized water, Group
II: received Fluoride-containing dentifrice and Group III: received Novamincontaining
dentifrice. All specimens were subjected to ESEM analysis and
Microhardness measurements. Results: group III showed complete remineralization
of enamel specimens while group II showed incomplete remineralization, comparable
to the baseline appearance. For evaluation of microhardness, Tukey post hoc test was
performed for multiple comparisons , and the results showed a significant trend,
where Novamin agent had the highest remineralizing effect, followed by Fluoride and
deionized water respectively(Þ < 0.0001).Conclusions: Novamin-containing
dentifrice exhibits a greater degree of remineralization than Fluoride -containing
dentifrice on artificial enamel lesions.
