Four finishing techniques for composite restoration were compared for the resultant surface roughness and the reduction rate using a light-cured microfilled composite and a self-cured hybrid filled composite. No significant difference in roughness was found between the two composites. The roughness was greatest with the Finishing Carbide bur and next with the White Point without irrigation. The least roughness was found with the Superfine Diamond and irrigated White Point with no statistical difference between the two. The reduction rate was greatest with the Superfine Diamond, followed by the Finishing Carbide bur. The smallest reduction rate was found with the White Point either with or without irrigation.
