An artificial anterior tooth having a more naturalistic or lifelike appearance for use in the design and/or production of a dental prosthesis and/or dental restoration is provided. The lingual-facing surface of an artificial anterior tooth is provided with a plurality of furrows in predetermined locations on the lingual-facing surface to correspond with a plurality of furrows on the labial-facing surface in predetermined locations on the labial-facing surface, so as to impart variable, lifelike color and/or translucency properties throughout the tooth.

The apparatus is an easily assembled, fluid cooled, single phase heat sink. The heat sink is constructed of only four simple parts, a pan shaped casing, a simple thermally conductive porous pad, a manifold block with channels, and a lid. The lid includes input and output fluid holes which are interconnected to sets of alternating channels in the manifold block, so that adjacent channels are isolated from each other and are connected to only either the input or the output holes. Thus, the only access between the adjacent input and output channels is through the porous pad which is sandwiched between the manifold block and the bottom of the casing. Fluid flow through the porous pad thereby cools the entire bottom of the casing which is held in heat transfer relationship with a heat source.
