Microbial colonization of denture bases plays a key role in the development of denture stomatitis and other oral conditions, with Candida albicans being the main etiologic agent [1,2]. The type of prosthetic material, manufacturing method, and oral hygiene habit determines the factors of biofilm formation [3].
This study aims to synthesize conclusions from recent review articles regarding the influence of material, surface finishing, and hygiene practices on the microbial colonization of denture bases. Three review articles (reviews and narrative reviews) were analyzed [1,2,3]. The focus was placed on microbial colonization of polymethyl methacrylate (PMMA) denture bases fabricated by conventional methods, CAD/CAM milling, or 3D printing, with or without surface treatments.
Milled PMMA exhibited the lowest level of microbial colonization, while 3D-printed resins were more susceptible, especially in the absence of surface glazing. Antimicrobial agents (e.g., ZnO or TiO2 nanoparticles) and rigorous hygiene practices significantly reduced biofilm formation. A notable synergistic relationship between Candida albicans and Streptococcus mutans was also reported, increasing the risk for chronic oral infections [4,5].
Material selection, surface finishing, and proper hygiene are critical to preventing microbial colonization on dentures. Further studies are needed to evaluate the long-term efficacy of antimicrobial modifications and to standardize microbiological testing protocols.
