Effect of phosphate group addition on the properties of denture base resins

Cold plasma-induced surface modification of heat-polymerized acrylic resin and prevention of early adherence of <i>Candida albicans </i>

“…It was found that the more hydrophobic a surface was, the greater the Candida albicans adherence by area unit 7) . Puri et al found that surface hydrophilicity was improved after phosphate was incorporated into an acrylic resin denture material by monomer substitution 31) . However, it also resulted in dimensional changes and color instability 31) .…”

“…Puri et al found that surface hydrophilicity was improved after phosphate was incorporated into an acrylic resin denture material by monomer substitution 31) . However, it also resulted in dimensional changes and color instability 31) . Recently, various coating approaches were developed and applied to denture base materials to increase surface hydrophilicity, with proven efficacy in reducing Candida albicans adherence 24,27,32) .…”

Flexural properties of ethyl or methyl methacrylate-UDMA blend polymers

“…This technique is effective to improve the mechanical properties; however it is very difficult to incorporate accurately reinforcing materials in the desired position of the denture base resin. Another approach is to apply other polymer materials [3][4][5] such as polycarbonate or nylon, to disperse a rubbery material 10) , such as butadiene, or to add a cross-linking agent [18][19][20] , such as dimethacrylate. However, the flexural modulus and the flexural strength of nylon denture base resin were lower than those of acrylic denture base resins.…”

Time-related surface modification of denture base acrylic resin treated by atmospheric pressure cold plasma

“…The adherence of C. albicans to acrylic resin denture base (polymethyl methacrylate -PMMA) has been thought to be the first step for successful colonization before subsequent plaque formation and development of pathogenesis 7,8) . Surface characteristics, such as surface roughness, hydrophilicity, and surface charge have all been reported to involve in the adherence of Candida [7][8][9][10][11] . Therefore, the development of methods that could modify these denture base surface properties to prevent the adherence of C. albicans would be a significant advancement in the prevention of Candida-associated denture stomatitis 8,9,12) .…”
