“…Group 1 comprised PMMA without NAg, whereas group 2 comprised PMMA mixed with 5 wt% NAg. The mean tensile strength of PMMA in group 2 was considerably lower than that in group 1, indicating that the incorporation of NAg resulted in a significant decrease in tensile strength [9].…”

Introduction: Nanotechnology has been established in dental specialities as a novel methodology for developing materials with enhanced physical properties and antimicrobial potential. In this review, we discuss the current progress, prospects, and potential future applications of functional nanoparticles contained in nanomaterials as useful strategies for refining their ability to resist occlusal forces, as well as oral biofilm management. We also provide an overview of the suggested antimicrobial mechanisms for these nanoparticles. The purpose of this study was to use an evidence-based approach to assess the possible applications of nanomaterials in various fields in contemporary and potential future dentistry. Methods:A comprehensive search of Medline (PubMed) and the ISI Web of Science database was carried out. Results: Nanomaterials have significant potential for decreasing bacterial biofilm accumulation, inhibiting the demineralization process, remineralizing dental tissues, and combating cariesrelated bacteria. However, their ability to withstand intraoral forces needs to be further improved. Conclusions:The results reviewed in this work present a bright outlook and open doors for future clinical studies that will allow admission of the therapeutic value of nanotechnology-based dental materials. Keywords: acrylic resins; graphene; nanocomposites; nanoparticles; silver. ABSTRAKT Wstęp: Nanotechnologia na dobre zagościła w poszczególnych specjalizacjach stomatologicznych jako nowatorska metodologicznie idea wdrażania materiałów o zarówno podwyższonych parametrach mechanicznych, jak i posiadających olbrzymi potencjał antymikrobiologiczny. Praca przedstawia obecny postęp, perspektywy, potencjalne przyszłe zastosowania oraz ograniczenia nanocząstek w aspekcie wytrzymałości określonych materiałów stomatologicznych oraz ich odporności na biofilm jamy ustnej. Celem niniejszego przeglądu piśmiennictwa była rzetelna analiza potencjalnych korzyści i zagrożeń wynikających z zastosowania nanocząsteczek w jamie ustnej w świetle medycyny opartej na dowodach, zarówno obecnie, jak i w niedalekiej przyszłości. Metody:Przeszukano bazy danych Medline (PubMed) i ISI Web of Science. Wyniki: Nanomateriały posiadają znaczący potencjał hamujący agregację płytki bakteryjnej, mogą przeciwdziałać procesom demineralizacji, remineralizować tkanki zębów oraz zwalczać określone typy drobnoustrojów. Jednakże ich zdolność do znoszenia dodatkowych obciążeń, a tym samym zwiększania wytrzymałości mechanicznej, nie znajduje potwierdzenia w obecnie dostępnym piśmiennictwie i wymaga dalszych badań. Również odległe skutki ich użycia, z potencjalną toksycznością włącz-nie, nakazują zachować dalece idącą ostrożność w stosowaniu. Słowa kluczowe: akryl; grafen; nanokompozyt; kompozyty; nanocząsteczki; srebro. ENDODONTICSMineral trioxide aggregates (MTAs) have been extensively used in all fields of endodontics. One of the major weaknesses of this material is the long setting time. Mineral trioxide aggregate is primarily composed of type 1 Port...

Background and aim:Polymethyl methacrylate (PMMA) is broadly used as a removable prosthesis denture base. Silver Nano-particles (AgNPs) had been included to PMMA because of their antibacterial homes and higher thermal conductivity, at the same time as it had a destructive effect on the flexural strength and coloration stability that is probably resulted from the inhomogeneous combination. The motive of this research changed into to discover whether the addition of (AgNPs) to PMMA either in liquid form or in powder nation can enhance the flexural strength and the shade balance of PMMA. Also evaluating an edentulous menopausal lady as a multidisciplinary control after wearing a denture made from silver nanoparticles added to (PMMA) denture base. Materials and methods:Fifty specimens of heat cure acrylic resin had been organized for flexural strength and color stability. Twenty-five for each test that become divided into 3 groups. Group 1 was the control group (unmodified acrylic resin specimens) and group 2 turned into Nano silver introduced within the form of powder to the polymer of (PMMA), while group 3 was Nano silver brought in the form of liquid to the monomer of (PMMA). Group 2 and 3 specimens had been break up into subgroups A and B 5 each, with 0.2%, and 0.4 % wt. of Nano silver addition to (PMMA) respectively. A flexural strength was measured via the usage of an Instron regular testing machine. A double beam ultra-violet visible spectrophotometer was checked to the degree of coloration stability. One edentulous menopausal woman that present process treatment below a gynecologist for menopausal signs and symptoms was selected as a case report and received denture made out of silver nanoparticles added to acrylic resin and patient satisfaction became evaluated after 4 months. The results have been gathered tabulated and statically analyzed.Results: There has been a massive distinction in the flexural power values among all corporations (p< 0.05) relative to the non-changed heat treatment (control group). Acrylic resin samples with 0.2% in liquid additive form (3A) ended in more flexural power then 0.4% addition (3B) in comparison to different changed groups .The samples with 0.4 % in powder form(2B) had a lowest (1514) Hoda A Rashad and Faten A S Abutaleb E.D.J. Vol. 64,No. 2 flexural strength in comparison to the all groups (p< 0.05). In comparing the color variations (ΔE) comparable to control group, group 3A and group 3B, showed lowest color variations respectively. At the same time group 2Aand 2B ended in highest shade distinction .Conclusion: Set up on the effects of this results, modifying PMMA with Nano silver debris led to lower in flexural strength and shade stability, addition of Nano silver particles in liquid shape was higher than powder form as concerning flexural strength and better color difference and the addition percentage of 0.2 became better than 0.4. Menopausal pride turned into higher and her complain became managed with the new denture.
