Abstract:
Objective:To evaluate the effects of different denture cleaners on the discoloration of heat-cured denture base resin and artificial teeth.Methods:40 same specifications of the heat-curing denture base resin and 40 artificial central incisors were immerced in an acombination stain of coffee,tea and soy sauce for 4 weeks.Then specimens and artificial teeth were randomly distributed into 4 groups and soaked in Polident,Steradent,0.5％ sodium hypochlorite solution and distilled water for 4 hours respectivelly(n =10).Color differences(△E) were measured by using a colorimeter and a denture spectrophotometer before and after staining,and after cleaning.Results:Before or after staining there was no difference of △E among the groups of denture base risn or artificial teeth(P ＞ 0.05).After cleaning the denture base resin and the artificial teeth in the group of 0.5％ sodium hypochlorite solution presented higher △E than the other groups(P ＜ 0.05),in group of distilled water presented lower △E than the other groups(P ＜ 0.05).No significant difference was found between Polident group and Steradent group(P ＞0.05).The △E of the denture base resin and artificial teeth.in distilled water group before staining and after cleaning were the highest among the groups(P ＜0.05).Conclusion:0.5％ sodium hypochlorite solution,Polident and Steradent are effective in removing the discoloration from the heat-cured acrylic resin and artificial teeth.0.5％ sodium hypochlorite solution is the most effective,Polident and Steradent are the similar.
