“…Due to some disadvantages of direct use of NPs including the objectionable taste of some additives and the necessity of frequent utilization that needs patient cooperation [ 31 ], the purpose of the present study was to assess the antimicrobial and antibiofilm effects of CuO NPs (in the mean diameter of 18.3 ± 9.1 nm) incorporated into soft denture liners.…”

Objectives. Soft denture liners provide a favorable environment for adhesion and colonization of microorganisms. This in vitro study aimed to examine the efficacy of different concentrations of copper oxide nanoparticles (CuO NPs) incorporation into soft denture liner on the biofilm formation of the microbial species. Methods. Field Emission Scanning Electron Microscopy (FESEM) images from NPs were recorded. Antifungal susceptibility testing of CuO NPs against five standard strains of Candida albicans (CBS 10261, 1905, 1912, 1949, 2730), Streptococcus mutans (ATCC35668), Streptococcus sobrinus (ATCC27607), and Streptococcus salivarius (ATCC9222) was performed by the broth microdilution method with the Clinical and Laboratory Standards Institute reference method. The biofilm inhibition percentages of CuO NPs on the soft denture liners were determined by XTT assay. Results. The characterization of CuO NPs by scanning electron microscope (SEM) analyses confirmed the synthesis of NPs with appropriate structure and size with a mean diameter of 18.3 ± 9.1 nm. The CuO NPs successfully inhibited the growth of the tested standard strains of C. albicans and Streptococcus spp. at concentrations ranging from 64 to 128 µg mL−1. Indeed, incorporation of CuO NPs at a concentration of 500 µg mL−1 into the soft denture liners exhibited a significant activity (75%) in inhibition of C. albicans. biofilm formation in a dose-dependent manner. The biofilm formation of C. albicans in the presence of CuO NPs was lower than Streptococcus spp. in comparison with the control group ( p < 0.05 ). Conclusion. Incorporation of CuO NPs significantly decreased the colonization and plaque formation of the oral pathogens, especially C. albicans accumulation. These NPs may be useful as a promising agent for the antimicrobial management of soft denture liner materials.

“…[ 24 ] Studies have found that incorporation of titanium dioxide nanoparticles in acrylic resins improved the antimicrobial properties by drastically reducing the bacterial adherence,[ 25 ] and the incorporation of silver nanoparticles reduced the colony-forming units of Candida albicans . [ 26 ] Several studies indicated that titanium dioxide nanoparticles have the ability to integrate with PMMA matrix both physically and chemically and produce free radicals that aid in its antimicrobial properties. [ 27 ] Silver nanoparticles act as a broad-spectrum antibacterial and antifungal agent while having low cytotoxicity.…”

Aim: Polymethylmethacrylate (PMMA) resin is the most by and large used denture base material. Denture fractures are sequential to the flexure or impacting forces. Different nanoparticles such as titanium dioxide and silver nanoparticles have been used to improve its antimicrobial properties. There are limited data on their effect on flexural strength. The aim of the study was to assess the effect of silver nanoparticles and titanium dioxide nanoparticles addition on flexural strength of PMMA resins. Settings and Design: One hundred and thirty specimens divided into four groups: Control Group A, TiO 2 -reinforced Group B, silver nanoparticles reinforced Group C, and mixture of TiO 2 and silver nanoparticle reinforced Group D. Each reinforced group further divided based on concentrations -0.5%, 1%, 2%, and 3%. Materials and Methods: Rectangular metal models of the American Dental Association (ADA)- specified dimensions: 65 mm × 10 mm × 3 mm were used to form a mold space for the fabrication of specimens. Three-point bend test was used to determine the flexural strength of the samples after immersion in distilled water for 2 weeks. Statistical Analysis: The data collected were subjected to analysis of variance followed by post hoc Tukey’s test. Results: The comparison of the mean flexural strengths showed a statistically significant gradual decrease on increasing the concentrations of nanoparticles. Maximal flexural strength was seen in the control group and least with 3% Ag + TiO 2 Nps. The modified specimen also showed color changes. Conclusions: In an in vitro environment, addition of TiO 2 and silver decreases the flexural strength of the PMMA. It also causes visible color changes.

“…Steel dies of size 10 mm × 2 mm were prepared according to the dimension quoted by Ramakrishna Alla in the year 2019. [ 6 ] Vernier caliper was used to measure the dimension of the dies. The standardized steel dies of 10 mm × 2 mm thickness were used to prepare the mold space for acrylic samples.…”

Aim: The intention was to determine the chemical interaction of silanized AgNPs with PMMA by Fourier transform infrared (FTIR) spectroscopy. Settings and Design: In-vitro comparative study. Materials and Methods: This study is composed of four groups – 0.75% AgNP, 1.0% AgNP, 1.5% AgNP impregnated with PMMA, and nonimpregnated PMMA as control. The chemical nature of silanized AgNPs was studied using FTIR study. Results: The results showed the appearance of new peak between 1727/cm and 1436/cm, i.e., 1636.476/ cm, 1645.886/cm, and 1646.885/cm, representing the C = C stretch in the experimental groups, i.e., 2, 3, and 4, respectively. This peak confirms that coupling agent has chemically interacted with PMMA. Conclusion: It can be concluded that the AgNPs coated with the silane coupling agent TMSPM has chemically reacted with PMMA.
