We evaluated the wettability of dentin and siliconize L-25 coated dentin (siliconized dentin) with water by measuring the contact angle. We also measured the contact angle of 4 elastomers with water and siliconize L-25. The siliconized dentin had a lower contact angle (25°) than dentin (93°). We also evaluated detail reproducibility by comparing surface roughness of dentin and stone casts made from impressions of dentin under six conditions. Spraying the denture lubricant on the dentin produced significant differences in surface roughness between the dentin and the stone casts. However, no significant difference in surface roughness was found between the dentin and the stone casts when treatment with siliconized dentin was followed by spraying with denture lubricant.
