Denture Debris

The fungal organisms that are most commonly associated with denture plaque are of the genus Candida.  These yeasts are present in the saliva of a majority of denture wearers and display an affinity for adherence to methacrylate resin.13  They are particularly effective at populating the "craters" formed by an intersection of a monomer bubble with the polished surface of the acrylic resin from which they are difficult to eradicate.13

Multiple innocuous and pathogenic bacterial varieties have been identified in denture plaque, including S. aureus, P. aeruginosa, E. coli, K. pneumoniae, alpha strep., beta-strep., Group D strep., and assorted gram (-) rods.14  Species of fusobacteria, which excrete volatile sulfur compounds associated with halitosis, have been identified as populous in denture plaque.15
