Translucency of clear acrylic resin influenced by oil paints

Abstract

Introduction: Clear acrylic resins are widely used in many applications in the field of dentistry such as removable complete and partial dentures. such materials are also used in the fabrication of scleral part of ocular prostheses when mixed with white oil paints. Therefore, the purpose of the present study was to evaluate the addition of oil paints on translucency of clear acrylic material. Materials and methods: The study included three main groups. Each group consists of 10 specimens. The concentration of white oil paints has increased from 1 ml to 2 ml, respectively. The translucency test was applied on all specimens. Results: The results showed that there was a significant decrease in translucency of acrylic following addition of white oil paints. Conclusion: the use of white paints has decreased the translucency of acrylic material. The adding of white oil paint at 1 ml to clear acrylic resin is necessary in the manufacture of the scleral part of ocular prostheses to match the colour of natural eye.
