Abstract : [Abstract] There are two methods of coloring or painting a maxillofacial prosthesis, intrinsic or extrinsic. Each has specific advantages and disadvantages. The extrinsic painting method is easy to use while the intrinsic way is more technique sensitive. However, the intrinsic method has better long-term color stability than the extrinsic method. Silicone specimens used in the experiments were fabricated from Factor II No.2186 Silicone Elastomer. The following article reports on color stability measurement using various methods of extrinsic coloration. The surface of each specimen was extrinsically painted. Different painting materials were used and the specimen was chemically sealed (treated). The amount of color omission from the surface of the extrinsically painted silicone specimens was measured by visual check and a color analyzer (CM-2022, Minolta). Measurement of some extrinsic coloring demonstrated exfoliation of the final sealing materia| from the base silicone halfway through the polishing procedure. The paint material was seen to exhibit minimal exfoliation from the experiment samples when the coloring kit contained a silicone element.
