Effect of Oil Paint Addition on Micro Hardness of Acrylic Ocular Prosthesis

Firas Abd Kati, Arshad F. Jassem Al-Kaabi


Introduction: Medical grade acrylic resin is the material of choice for many dental and facial restorations. When making artificial eye from this polymer, it is highly required to apply the perfect shade matching the original one. However, this may have some significant effect on the mechanical properties as well as surface integrity since most types of paints used with acrylic resin are oil paints. The aim of this study was to evaluate the effect of oil paint addition on acrylic resin surface hardness.

Methods: The study consisted of 3 main groups (control, white 1, and white 2). Each group consisted of 10 samples. The paint concentration was increased from white 1 to white 1 respectively. Vickers hardness test was applied on all samples.
Results: The statistical results showed that there was a significant increase in the acrylic surface hardness as the oil paint concen- tration increases (p-value < 0.05).

Conclusion: A conclusion drawn from this study that the oil paint would have significantly increase the acrylic eye prosthesis hard- ness but it might be to a certain level.
