Objective: To evaluate and compare the topographical features of enamel surface, etched with different materials. Study Design: 10 extracted human primary molars were randomly selected and cut and trimmed to 1 mm2. Each group comprised of 10 blocks and the enamel was treated as follows: Group I–35% H3PO4; Group II–5.25% NaOCl + 35% H3PO4 ;Group III–5.25% NaOCl; Group IV no treatment was carried out. All the samples were prepared for Scanning electron microscope analysis. The images were obtained and evaluated for the quality type I–II etching of the enamel surface using Auto-CAD 2011 software. Statistical Analysis Used: Wilcoxon Signed Ranks Test (p<0.001). Results: The mean surface area of type I and II etching pattern values for Group- I was 39608.18 μm2 and Group- II was 45051.34 μm2. Conclusion: Deproteinization with 5.25% Sodium hypochlorite prior to acid etching could be used to increase the surface area of adhesion of composite material with the tooth surface.
