The effect of thickness on the color parameters of the vinyl addition maxillofacial elastomer

الملخص EN

Aim of the study : The study investigated the effect of material thickness on color parameters of maxillofacial silicon.

Materials and methods : Sixty samples made of silicone rubber.

Samples (20 * 103) mm length, width, thickness, and (20 * 10 * 1.5) mm length, width, and thickness were divided into three groups, white, yellow and pink (10 samples a thickness of 3 mm and 10 samples thickness of 1.5 mm in each group).

And then the samples were tested for recording color parameters.

Results : There was a significant difference for the three color values at different thicknesses, where the value of * L and a * in the three groups decreased as thickness increased while the b * value rose up with the thickness.

Conclusions : The increase in the thickness of the maxillofacial silicon associated with a decrease in the value of L *, a * and a rise in the value of b.
