Abstrakt: Objectives : Storing of dentures in the denture cleansers containing sodium perborate or sodium hypochlorite has been advocated to prevent the bacterial growth, plaque accumulation & calculus formation on the denture which may further lead to debonding of soft liner from denture base, thus shortening of useful life of complete denture necessitating the reapplication of the soft liner. The objective of this study was to test the effect of denture cleansers on tensile bond strength of Permanent Soft liner to Poly Methyl Methacrylate. Method : Specimens of standardized dimensions were fabricated with a specially prepared stainless steel die. Each specimen consisted of two Poly Methyl Methacrylate blocks with Permanent soft liner of uniform thickness of 3mm interposed between them. The specimens were divided into groups comprising of different storage conditions viz storage in artificial saliva or in denture cleanser. All specimens were tested for tensile bond strength after 1 month, 3 months & 6 months using Universal Testing Machine. Results were compared and subjected to statistical analysis. Results : It was found that storing of specimens in denture cleansers containing sodium perborate or sodium hypochlorite did not significantly reduce the tensile bond strength of Permanent Soft liner to Poly Methyl Methacrylate. Conclusions : Within the limitations of this in vitro study the denture cleanser tested, did not cause significant changes in the tensile bond strength of soft denture lining material to Poly Methyl Methacrylate for the time period tested.
