Denture adhesives are shunned by dentists because their use implies that their exquisitely crafted prosthesis lacks retention and stability. But could denture adhesives indeed cause harm by impairing denture hygiene such that they exacerbate denture-derived stomatitis or indeed cause aspiration pneumonitis? The aim of this study was to examine if denture cleansers could mitigate such untoward events by removing different types of denture adhesives. In this in vitro study, they categorised visually the efficacy of denture cleaners to remove powder, cream or cushion adhesives on acrylic specimens. It would appear that although denture cleaners could liquefy cream adhesives, this requires immersion in denture cleaners for over 12 hours. Such would advocate the use of mechanical cleaning. Cushion adhesives were the most stubborn with denture cleaners having no effect on their removal. All denture adhesives and denture cleaners were Japanese brands although some were made by international companies.
