|
Purpose: The purpose of this study was to evaluate the effect of denture cleansers on the flexural bond strength of heat curing denture base resin and reliners.
Methods: The denture base resin was bonded to the reliners(vertex self curing, kooliner, rebase Ⅱ) to make the specimen. The specimens were immersed in denture cleansers(Polident, Cleadent) and evaluated after 1week, 3week, 5weeks. After denture reliners were injected, flexural bond strength was measured.
Results: The bond strength of denture base resin and vertex self curing resin as reliner was significantly decreased at 5 weeks in cleadent and polident(p<0.05). The bond strength of kooliner and rebase Ⅱ was significantly decreased at 5 weeks in denture cleaners(p<0.05). Kooliner was significantly decreased at 3 and 5 weeks in polident and rebase Ⅱwas significantly decreased at 3 and 5 weeks in all denture cleansers(p<0.05).
Conclusion : The flexural strength between the denture base resin and the reliners decreased significantly as the treatment time increased.
