Abstract: Objective:To evaluate the effect of thermocycling on nano-silver-incorporated silicone denture liner for Candida albicans (CA)adhesion.Methods:Specimens(1 0 mm ×1 0 mm ×3 mm)of silicone denture liner(control)and that incorporated with nano-sil-ver were prepared according to the manufacturer's direction.8 of the each kind of specimens were immersed in distilled water for 24 h at 37 ℃,and 8 were subjected to thermocycling for 4 000 cycles at temperatures ranging from (5 ±1 )℃to (55 ±1 )℃with a 60 s dwell time per temperature.In vitro CA adhesion assay was used to measure the levels of adherence to the specimens.Data were analysed sta-tistically.Results:Thermocycling increased CA adhesion to control specimens(P<0.05),and did no change the adhesion to nano-sil-ver incorporated specimens(P>0.05 ).The adhesion of CA to nano-silver incorporated specimens was fewer than that to the controls with or wihout themocycling(P<0.01 ).Conclusion:Nano-silver incorporation may inhibit CA adhesion to silicone denture liner.Ther-mal cycling has no influence on C.albicans adhesion to silicone denture liner incorporated nano-sliver.
