摘　　要：To reduce the burden of denture stomatitis and oral candidiasis,an aqueous solution containing polyhexamethylene guanidine hydrochloride(PHMGH)was investigated as an antifungal disinfectant against the leading cause of these oral conditions,Candida albicans.The solutions formulated with concentrations ranging from 0.125 to 0.50 wt%enabled increasing disinfection at the initial 5min-contact with 72h-mature candida biofilms formed on denture liner specimens.After 10 min-contact,the solution at lower concentration has reached total fungal elimination.The results also indicated that the denture liners preserved their mechanical property after the maximum contact time with the solution at the highest tested concentration.The PHMGH aqueous solutions at 0.125 wt%could be applied to promote interim denture liner disinfection without promoting the loss of materials’mechanical property.
