“…The results of the current study indicate that the size of the added TiO 2 NP did not affect the observed antimicrobial effect and SH as studies that used smaller TiO 2 NP (less than 50 nm) 52,53,55,57,58 as well as those that used relatively larger sized NPs (greater than 50 nm), 45,51 reported improved antimicrobial properties. Previous studies have found that smaller sized NPs improve properties as they can penetrate between linear chains and form homogenous mixture, and additionally can easily attach and penetrate cell membranes.…”

“…57 With regards to the SR, Cascione and others found a decrease in SR with large sized TiO 2 NP (greater or equal to 50 nm), 51 but three studies reported an increase in SR with the addition of less than 50 nm TiO 2 NP, 46,50,52 and one study found in-significant improvement in SR. 58 Three studies found an increase in the SR on addition of 3% and 2% TiO 2 NP, 46,50,52 while one study found 54% and 72% roughness reduction with 1% and 3% TiO 2 NP, 51 and one study found an insignificant increase in SR with 5% TiO 2 NP. 58 Contrary to the effect on SR but similar to antimicrobial effect, SH was found to increase irrespective of the size of the added TiO 2 NP. Studies that used TiO 2 NP less than 50 nm particle size 41,46,48,54,56,50 as well as greater than 50 nm reported improved SH.…”

“…37,42 Only one study used high impact acrylic resin and found that the hardness further increased by addition of 5 % TiO 2 NP, the difference being statistically significant. 48 Despite the fact that polishing of the acrylic affects the surface properties and subsequent microbial adhesion, only seven studies were found to have mentioned the procedures adopted for finishing and polishing 44,45,49,51,53,58 and six studies mentioned details of sample storage. 45,46,48,52,54 The methods of dispersion and surface treatments of NPs play a significant role in affecting the mechanical properties.…”

Background: Polymethyl Methacrylate (PMMA) denture-base resins have poor surface properties that facilitates microbial adhesion causing denture stomatitis. This systematic review aims to evaluate the effect of different sizes and percentages of titanium dioxide nanoparticles (TiO2NP) on the antimicrobial property, surface roughness and surface hardness of PMMA denture base resin. Methods: A systematic search of English peer-reviewed articles, clinical trial registries, grey literature databases and other online sources was performed using the PRISMA-S Guidelines for In-Vivo and In-Vitro studies. Qualitative data synthesis was performed to analyse sample dimensions, acrylic used, treatments of nanoparticles, methods used for testing and effect of size and percentage of nanoparticle. Risk of bias assessment was done using modified Cochrane risk of bias tool. Results: Out of 1376 articles, 15 were included. TiO2NP of size less than 30 nm was most frequently used. Both antimicrobial property and surface hardness improved irrespective of the size of the added TiO2NP. Three studies reported increase in the surface roughness with less than 50 nm TiO2NP. 3% TiO2NP was most frequently used. On increasing the percentage, three studies reported an increase in antimicrobial property, while two studies found no change. With TiO2NP greater than or equal to 3%, six studies reported an increase in surface hardness, while two reported increase in surface roughness. Large methodological variations were observed across studies. All studies except one were of moderate quality. Conclusions: On addition of TiO2NP to heat polymerized PMMA, the antimicrobial property and surface hardness improved irrespective of the size of the TiO2NP, however, addition of nanoparticles less than 50 nm increased the surface roughness. Increasing the percentage of TiO2NP increased the surface hardness but did not always increase the antimicrobial property. Addition of 3% TiO2NP provided optimum results with regards to antimicrobial effect and surface hardness, but increase in the surface roughness.

Aim: This study was performed to examine the anti-microbial effect of different percentages of titanium dioxide and chitosan nanoparticles to heat cured poly methyl meth acrylate .Subjects and methods: 120 specimens of heat cure acrylic resin were grouped according to nano additives concentrations for testing anti-microbial effect. Results: the addition of chitosan nano particles to PMMA in 0.3% and 0.5% decreased the microbial biofilm formation in comparison to the control (PMMA without chitosan). the addition of Tio2 nano particles in concentrations 1% and 2% decreased the microbial biofilm formation more than the chitosan nano particles concentrations 0.3 and 0.5. Conclusion: The addition of chitosan nano particles to PMMA in 0.3% and 0.5% decreased the microbial biofilm formation in comparison to the control (PMMA without chitosan). the addition of Tio2 nano particles in concentrations 1% and 2% decreased the microbial biofilm formation more than the chitosan nano particles. The higher concentrations of the chitosan and Tio2 nano particles resulted in stronger antimicrobial effect.
