Color changing in denture base polyamide 12 and polyamide microcrystalline after polishing in laboratory and dental clinic

[摘要] This study's purpose was to compare color changes from polyamide 12 and polyamide microcrystalline materials. Each material was divided into two groups, polished with laboratory and clinical polishing equipment, and then immersed in a 28° C coffee solution for seven days. Surface roughness was measured with a profilometer before the immersion. Color (L∗, a∗, and b∗) was measured using a spectrophotometer before and after immersion. There were no significant color changes in the polyamide 12 and polyamide microcrystalline materials after immersion in the coffee solution.
