Abstract

Aim: To evaluate and compare the surface roughness (Ra) induced by topical fluorides on porcelain fused to metal surface at different intervals of time.  Materials and Method: An in vitro study was undertaken to evaluate the surface roughness of porcelain fused to metal samples induced by different topical fluorides Sodium Fluoride (2%) Stable Stannous Fluoride (0.4%), Sodium Fluoride (4.4 mg) and Sodium Fluoride (1.23%) at different time intervals of 16 minutes, 32 minutes, 6 hours and 12 hours. For this study, total 64 samples were fabricated. The samples measuring 10 mm×10 mm×1.5mm. The 64 samples were then divided into four groups. These samples were then evaluated for surface roughness with the help of Zeta 20 optical profiler. Results: The readings of all the procedures were noted, tabulated and analyzed statistically using Tukey’s and Anova test. The results of this study showed least surface roughness with Sodium Fluoride (2%) (Colgate® Total toothpaste), Stable Stannous Fluoride (0.4%) (Colgate® Gel.kam toothpaste), Sodium Fluoride (4.4 mg) (Colgate® Phos-flur mouthrinse) as compared to Sodium Fluoride (1.23%) (Topical Fluorovil Thixotropic Gel).  Conclusion: Sodium Fluoride (1.23%) (Topical Fluorovil Thixotropic Gel) induced greater amount of surface roughness on porcelain fused to metal samples as compared to that of Sodium Fluoride (2%) (Colgate® Total toothpaste), Stable Stannous Fluoride (0.4%) (Colgate® Gel.kam toothpaste) and Sodium Fluoride (4.4 mg) (Colgate® Phos-flur mouthrinse).
