摘要：

In this paper a simple technique for surface roughness estimation of composite dental material samples widely used in modern stomatology is presented. The proposed method is easily applicable and based on statistical properties of diffusely scattered laser light. The main challenge we addressed was the specific structural and optical properties, as well as the complex geometric shapes of real dental restorations. A relation between surface roughness and speckle contrast, used in the presented method, is verified.
