Abstract:
Objective To evaluate the effect of different cleaners on the color stability of two silicone rubbers used for maxillofacial prosthesis,and to provide recommendations for clinical use.Methods Thirty skin-color columniform specimens(12 mm diameter,10 mm height)of two silicone rubber(A:A-2000;Z:ZY-1)were prepared,randomly divided into 6 groups according to the table of random number,and cleaned with the following solutions:isopropyl alcohol(I),three kinds of denture cleaners(P:Polident,S:Steradent,C:Cleansofi)and distilled water(D),simulating the total immersion time of 1 year (1,15,10,3 and 10 min each time respectively).Control group was kept in dark place without treatment.The L*,a*,b* value were tested before and after immersion.Then color difference value was calculated.Results Color differences were different among groups.Color difference in group I(A:2.15,Z:2.00)were significantly greater than that in any other group.There were no significant differences between groups using denture cleaner P(A:0.36,Z:0.36),C(A:0.42,Z:0.37)and S(A:0.33,Z:0.38),and group D(A:0.22,Z:0.23).Conclusions Isopropyl alcohol causes the most severe fading,and denture cleaners and distilled water cause obscure fading.
