“…The increase in surface roughness increases the hydrophobicity of the surface that accelerates candida adhesion 30) . Thus, the surface roughness is an accelerating factor in the adhesion of fungus 22) . The increased surface roughness at 20 wt% content might have offset the inhibitory effect of the released ions.…”

Effect of incorporation of surface pre-reacted glass ionomer filler in tissue conditioner on the inhibition of <i>Candida albicans</i> adhesion

We investigated the effects of incorporation of surface pre-reacted glass ionomer (S-PRG) filler in tissue conditioner (TC) on Candida albicans adhesion. We prepared specimens containing 0, 5, 10, or 20 wt% of S-PRG filler, and measured the amount of C. albicans on the surface using a colony forming unit (CFU) assay and scanning electron microscopic images. In addition, we measured the consistency, penetration depth, and surface roughness (Ra). CFU values for 10 and 20 wt% were significantly lower than that for the control (p<0.05). Hyphal density on the surface was greater in the control. The 10 and 20 wt% specimens showed significantly higher consistency and Ra, lower penetration depth ratio than control (p<0.05). These results suggest that incorporation of S-PRG filler may reduce C. albicans adhesion onto TC surface; however, the optimal amount of filler is dictated by the influence of filler incorporation on mechanical and surface characters of TC.

“…11,14 Besides to the degradation between soft liners and PMMA resin interface, C. albicans biofilm accumulation led to a greater overall degradation. This is probably related to the ability of C. albicans hyphae to adhere and penetrate into soft liners, 20,21 as well as the production of proteases and phospholipases. 22,23 Thus, it is important to consider the degradation of the soft liner itself, which makes the material more susceptible to tearing.…”

Candida albicans biofilms and MMA surface treatment influence the adhesion of soft denture liners to PMMA resin

et al. 2014

The effect of Candida albicans biofilms and methyl methacrylate (MMA) pretreatment on the bond strength between soft denture liners and polymethyl methacrylate (PMMA) resin was analyzed. Specimens were prepared and randomly divided with respect to PMMA pretreatment, soft liner type (silicone-based or PMMA-based), and presence or absence of a C. albicans biofilm. Samples were composed of a soft denture liner bonded between two PMMA bars. Specimens (n = 10) were incubated to produce a C. albicans biofilm or stored in sterile PBS for 12 days. The tensile bond strength test was performed and failure type was determined using a stereomicroscope. Surface roughness (SR) and scanning electron microscopy (SEM) analysis were performed on denture liners (n = 8). Highest bond strength was observed in samples containing a silicone-based soft liner and stored in PBS, regardless of pretreatment (p < 0.01). Silicone-based specimens mostly underwent adhesive failures, while samples containing PMMA-based liners predominantly underwent cohesive failures. The silicone-based specimens SR decreased after 12 days of biofilm accumulation or PBS storage, while the SR of PMMAbased soft liners increased (p < 0.01). The PMMA-based soft liners surfaces presented sharp valleys and depressions, while silicone-based specimens surfaces exhibited more gentle features. In vitro exposure to C. albicans biofilms reduced the adhesion of denture liners to PMMA resin, and MMA pretreatment is recommended during relining procedures.

“…Lining materials have been found to be more prone to microbial adhesion than acrylic resin base materials and have been demonstrated to interact with oral microorganisms because of their surface texture and the physical/chemical affinity between the materials. Surface roughness of the resilient liners may differ among materials (Zissis et al, 2000;Jin et al, 2003), and rougher surfaces enhance the adhesion of microorganisms onto resilient lining materials (Bulad et al, 2004) that may allow fungal growth (Brosky et al, 2003). The microorganisms from the plaque on the denture surface may expose patients and dental personnel to infection (Witt et al, 1990).…”
