Nano-graphene oxide incorporated into PMMA resin to prevent microbial adhesion

Enamel Anti-Demineralization Effect of Orthodontic Adhesive Containing Bioactive Glass and Graphene Oxide: an in-Vitro Study

“…In this study, an orthodontic adhesive with 1 wt.% of BAG@GO showed no statistically significant difference in micro-hardness when compared to existing orthodontic adhesives, but those with 3 wt.% or 5 wt.% of BAG@GO showed a significant increase in micro-hardness. This result corresponds with the results of the research performed by Lv et al; composite with graphene nano sheet and 0.5 wt.% or 1.0 wt.% of HA showed 30-40% increase in microhardness, and PMMA with 0.5, 1.5, 2.0 wt.% of nano-GO showed an increase in Vicker's hardness [9][10]. This is because the stable layer structure of GO acts as an effective filler in the material, subsequently increasing the microhardness.…”

“…This supports the result that 48 hour-group of BAG@GO shows higher antibacterial activity than 24 hour-group. Research shows that GO is effective against dental pathogens, as well as general bacteria [6,9].…”

Activity of chitosan antifungal denture adhesive against common Candida species and Candida albicans adherence on denture base acrylic resin

“…As Candida colonization and denture stomatitis are common problems, efforts have been made to minimize Candida adherence to denture bases, including modifications of denture base materials and addition of antimicrobial agents into denture adhesives, such as miconazole microparticles. 39,40 The use of HMWC in denture adhesive is an additional method that is advantageous in several aspects. Because the mechanisms of action of chitosan are different from those of antifungal drugs, it could be effective in patients with refractory disease.…”

Carboxylic acid-functionalized TiO2 nanoparticle-loaded PMMA/PEEK copolymer matrix as a dental resin for 3D complete denture manufacturing by stereolitographic technique

“…[1][2][3][4][5] Dental composite resins are generally designed of resin polymer matrixes with inorganic nano-fillers and initiating agents. [6] In the recent materials, researchers have increased large attentions on nano-inorganic materials assisted with organic hybrid composites because of their prospective applications in different areas such as sensors (bio-and chemical-), electronics, energy, plastic reinforcement, and particularly biomaterials for bone and dental regeneration applications. [7][8][9][10][11] The composites synthesized for dental restoration used by a combination of different shape and sized suitable inorganic nanoparticles encapsulated with the cold-cure acrylic polymeric matrix.…”

“…The PMMA polymer matrixes have extensively been applied in dentistry restorations for widespread denture preparations due to their luxury processing for dental repair, cost-effective, tasteless, odorless nature, transparency, great suitability and biocompatibility to the patients, and also outstanding esthetic characteristics. [6,[12][13][14] Polyethereketone (PEEK) is a semicrystalline polymer (crystallinity = 30-35%), which has been applied as a potential material for the dental and bone implant due to its favorable glass transition temperature (143°C) and excellent elastic modulus for the ease of molding to 3D printed materials. [15,16] The dispersion of effective inorganic nanoparticles into the polymeric composite resins can be progressed and greatly influenced by some potential resin restoration properties of nanoparticles such as suitable modulus, active flexural strength, wear resistance, and gloss retention.…”
