“…On the other hand, an increased roughness may foster biofilm adhesion in vivo. Surface roughness, amongst other factors like material properties, is a known contributor to oral biofilm adhesion 26,27) . Hence the absence of a significant difference in cell growth may be due to two counter-acting effects.…”

This study compared the biocompatibility, mechanical properties, and surface roughness of a pre-polymerized polymethyl methacrylate (PMMA) resin for CAD/CAM complete removable dental prostheses (CRDPs) and a traditional heat-polymerized PMMA resin. Two groups of resin substrates [Control (RC): conventional PMMA; Test (RA): CAD/CAM PMMA] were fabricated. Human primary osteoblasts and mouse embryonic-fibroblasts were cultured for biocompatibility assays. Mechanical properties and surface roughness were compared. ANOVA revealed no difference between the resin groups in the biocompatibility assays. RA demonstrated a higher elastic modulus (p=0.002), young's modulus (p=0.002), plastic energy (p=0.002), ultimate strength (p=0.0004), yield point (p=0.016), strain at yield point (p=0.037), and toughness (p<0.0001); while RC displayed a higher elastic energy (p<0.0001). Laser profilometry concluded a rougher surface profile (p<0.0001) for RA. This study concluded that the tested CAD/CAM resin was equally biocompatible and presented with improved mechanical properties than the traditional heat-polymerized PMMA resin used in the fabrication of CRDPs.

“…The hyphal form has higher pathogenic potential, as it can penetrate the surface of and invade epithelial tissue 28) . Another study has reported that inhibition of the transition from the yeast to hyphal form reduces biofilm formation 29) . Thus, inhibition of hyphal expression on the TC surface may decrease the pathogenicity of C. albicans and biofilm formation.…”

Effect of incorporation of surface pre-reacted glass ionomer filler in tissue conditioner on the inhibition of Candida albicans 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.

“…Candida biofilm development on denture acrylic resin begins with adhesion, which can either occur directly to the conditioned surface or via a layer of pre-existing denture plaque. 1 The surface irregularities increase the probability of bacterial accumulation, and Candida adhesion than smooth surface, surface roughness of prostheses providing niches in which the microorganisms are protected from sheer forces and oral hygiene measures. The surface of the resins used in the construction of the prosthesis can be finished and polished using variety of techniques.…”
