Abstract
Objective:
Aim: this study aimed to assess surface microhardness of Enamel ProVarnish Amorphous calcium phosphate (ACP)*(Premier Dental Products, PA, USA) containing fluoride varnish and Icon resin infiltration (Icon-Infiltrate) ** (Resin Infiltration Icon DMG, Hamburg, Germany) after remineralization of artificial enamel lesion of extracted primary anterior teeth
Materials and Methods: eighty primary anterior teeth, which were randomly assignment into two equal groups: Group A and Group B (n=40 per group). Each group was further divided into two subgroups (n=20 per subgroup) according to sealant type: Group I: Enamel ProVarnish (control) and Group II: Icon Resin Infiltrate (intervention). Each group Microhardness test and Streptococcus Mutans adhesion were evaluated.
Results: Group II Icon resin infiltrate showed significantly higher microhardness and bacterial adhesion than Group I Enamel ProVarnish (p < 0.05).
Statistical analysis: Data were analyzed using Statistical Package for Social Science (IBM SPSS Statistic for window version 22.0. Armonk, NY: IBM Crop.). After testing data for normality, paired means of surface Microhardness and number of adhered colonies of bacteria for each group (Enamel ProVarnish and ICON groups) were analyzed using Paired Samples t-test. Independent Student t-test was used to compare means of surface Microhardness and number of adhered colonies of bacteria of both groups. Statistical significance level was set to 5% at 95% CI.
Conclusion: Icon resin infiltrate was significantly superior difference than Enamel ProVarnish in surface Microhardness while Enamel ProVarnish was significantly difference than Icon Resin infiltrate in Streptococcus Mutans adhesion.
