ABSTRACT
Objective:
To evaluate the staining of different resin artificial teeth treated by different coloring agents.Methods:
1 6 teeth of each brand of Endura Anterio,Heraeus's three color synthetic resin teeth,synthetic resin teeth,Efucera-A,KaiFeng synthetic resin teeth were respectively made into test specimens.A surface roughness tester was used to measure Ra along 3 tracks on each sur-face.The specimens of the same brand were respectively immersed into coffee,tea and vinegar as the test groups and distilled water as a control for 4 weeks.The initial and further color of each specimen was measured using a colorimeter.The CIE L* a* b* values were recorded and color differences (ΔE)after immersion were calculated.Data were statistically analyzed by ANOVA.Results:
The color stability of the specimens in coffee and tea was significantly affected by the coloring agents(P 0.05).The ΔE values in the same coloring agent were as followsEfucera-A,Heraeus's three color synthetic resin teeth,Endura Anterio,synthetic resin teeth and KaiFeng synthetic resin teeth (P <0.05).Conclusion:
Extrinsic pigment can make resin artificial teeth stained,and the staining susceptibility of five resin artificial teeth is different.
