Objective

The aim of this study was to examine the surface hardness of denture base resins after immersed in four commercially available denture cleansers solution.

Study Design

In vitro experimental study.

Methodology

A Total of one hundred and four specimens of measuring 13 mm×4 mm were fabricated. These 104 specimens were randomly divided into six groups. Each group consists of 18 specimens. These groups were: baseline (0 day dry), artificial saliva (control);Fittydent denture cleanser tablets;Fixodentdenture cleanser tablets, polident and corega. After 60 days of immersion in their respective experimental group, the specimens were tested for Vickers microhardness with Vickers microhardness tester.Statistical analysis was carried out by using SPSS 16 version.

Result

There was statistically significant difference in the surface hardness among all groups (p < 0.001) after 60 daysof immersion.

Conclusion

Surface hardness of denture base resins decreased after immersion in denture cleansers.

Keywords

Denture base, Denture cleanser, Vickers microhardness.
