Abstract:

BACKGROUND: There are many cases in clinic that complete denture base surface has pigmentation, but the discolor in metal mesh stent surface and the surrounding materials in denture base is very rare.
OBJECTIVE: To analyze the reason of a complete denture base and metal mesh stent abnormal discoloration in one case.
METHODS: Part of discolored uniform base were taken as samples, the surface changes was observed and recorded by stereo microscope. The discoloration materials were acquired, and Fourier infrared spectral analysis was used to compare the discoloration materials and surrounding normal base.
RESULTS AND CONCLUSION: The sample base was observed to show large area cracks by stereo microscope and the maximum width was measured at 860 nm. Infrared spectral result indicated that the wave of discoloration materials was similar to the normal base, there was not observed oxide characteristics peak. This gives us a cue that the discoloration lies in the surface cracks caused pigmentation.
