Statement of Problem: Adjustment of ceramic restorations either before or after cementation results in surface roughness. This leads to adherence of Streptococcus mutans at restored tooth margins to cause recurrent caries.

Purpose: To evaluate and compare the adhesion of S. mutans on auto glazed and chair side polished surface of two feldspathic ceramics.

Materials and Methods: 60 circular ceramic discs, 30 of each material, IPS e max Ceram (Ivoclar Vivadent AG. Schaan) and IPS d. SIGN (IvoclarVivadent AG. Schaan) were fabricated. To simulate chairside adjustments, all the specimens were abraded for a minute with Shofu yellow finishing diamond points. Six groups were made. (10 specimens per group) i.e. IPS e max Ceram: Group A1 (auto glazed), Group A2 (polished with optrafine), Group A3 (control). IPS d SIGN: Group B1 (auto glazed), Group B2 (polished with optrafine), Group B3 (control). The surface roughness of each specimen was assessed before incubation with S. mutans for 48 hours at 37°C with Brain Heart Infusion broth. After sonication and dilution, adherent bacteria were plated for quantification using the plate count method to assay for colony forming units (CFUs). Statistical analysis was performed using 1 way anova and Post Hoc Test.

Results: CFUs (cells/mL) of S. mutans were significantly highest for chairside adjusted IPS d SIGN (5.70E+03) followed by chairside adjusted IPS e max Ceram (4.25E+03) which were not significantly different from each other (p < 0.05). Glazed IPS d SIGN (6.56E+02), followed by Glazed IPS e max Ceram (6.31E+02) with no significant difference within them (p < 0.05). Least bacterial adhesion was noted with optrafine polished specimens; IPS d SIGN (1.52E+02) followed by IPS e max Ceram (1.38E+02) with no significant difference within them (p < 0.05).

Conclusion: There is no significant difference in adhesion of S. mutans between both the ceramic systems.
