摘要
摘要用于修复体底座的丙烯酸树脂会积累生物膜,引起口腔炎等疾病。添加一些纳米颗粒可以促进抗菌作用。本研究通过两种方法将银纳米粒子修饰的纳米结构钒酸银(AgVO3)加入丙烯酸树脂中,并对其对人牙龈成纤维细胞(HGF)的细胞毒性及释放的银和钒离子进行了评价。分别以0.5、1、2.5和5%浓度的AgVO3通过真空搅拌和聚合膜掺入。在Turbomix设备上进行真空搅拌60 s,将聚合物在氯仿中增溶得到聚合物膜,对聚合物膜进行低温研磨,并在单体上手动混合得到的粉末。24小时、7天和14天后,采用MTT法测定HGF细胞活力。30天后用电感耦合等离子体质谱法测定银(Ag)和钒(V)离子的释放。采用Kruskal-Wallis和Dunn检验(α = 0.05)。HGF活力与孵育时间成反比。除真空挤压5% AgVO3组24小时存活率高于阴性对照组(p=0.013)外,阴性对照组和阴性对照组的存活率均有统计学差异(p < 0.05)。Ag、V离子释放量与AgVO3浓度成正比,5%组与其他组比较差异有统计学意义(p<0.05)。综上所述,含AgVO3和未含AgVO3的丙烯酸树脂在24小时内对HGF具有较小的细胞毒性,接触时间越长,活性越低;Ag和V离子的释放与AgVO3浓度成正比,不影响细胞活力。关键词:丙烯酸树脂;细胞的生存。纳米技术。离子。还原树脂的利用是一种基于蛋白质积累的生物膜、原因和结构的合成材料。一种海藻纳米颗粒促进抗菌素的产生。采用纳米结构、纳米颗粒、纳米结构、纳米颗粒、纳米结构、纳米颗粒、纳米结构、纳米结构、纳米颗粒、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构、纳米结构。当AgVO3的浓度分别为0.5%、1%、2.5%、5%和5%时,可获得较好的真空膜聚合物。一个真空espatulacao信息自由realizada为什么60年代没有equipamento Turbomix, e o filme polimerico信息自由obtido从da solubilizacao polimero em cloroformio, o filme信息自由submetido乌玛moagem criogenica e o阿宝obtido信息自由misturado manualmente ao monomero。HGF细胞可存活24小时,7小时,14小时。用定量差谱法研究了等离子体等离子体诱导等离子体在30个介质中的作用。Os testes de Kruskal-Wallis e Dunn foram应用者(α= 0.05)。HGF的可行性与投资成正比。随着技术的纳入,各组控制性阴性阳性表现差异有统计学意义(p < 0.05),除控制性阴性表现为5%的AgVO3组外,其余24组控制性阴性表现为主要阳性表现(p < 0.05)。AgVO3的浓度与AgVO3的浓度成正比。0组(5%)与正常组比较差异有统计学意义(p < 0.05)。综上所述,在HGF的24小时内,AgVO3的浓度可能与HGF的潜在毒性有关,而AgVO3的浓度与HGF的潜在毒性无关,AgVO3的浓度与HGF的潜在毒性无关,AgVO3的浓度与HGF的潜在毒性无关。palavras - have: Resinas acrilica。Sobrevivencia Celular。Nanotecnologia。离子。
Cytotoxicity and Elemental Release of Dental Acrylic Resin Modified with Silver and Vanadium Based Antimicrobial Nanomaterial
AbstractThe acrylic resin used for the prosthesis base accumulates biofilm, causing diseases such as stomatitis. The addition of some nanoparticles promotes antimicrobial action. This study incorporated the nanostructured silver vanadate decorated with silver nanoparticles (AgVO3) to the acrylic resin by two methods and evaluated the cytotoxicity for human gingival fibroblasts (HGF) and the released silver and vanadium ions. The concentrations of 0.5, 1, 2.5, and 5% of AgVO3 was incorporated by vacuum spatulation and polymeric film. The vacuum spatulation was performed for 60 s using the Turbomix equipment, and the polymeric film was obtained from the polymer solubilization in chloroform, the film was subjected to a cryogenic grinding, and the powder obtained was manually mixed at the monomer. HGF cell viability was assessed after 24 hours, 7 and 14 days by the MTT assay. The release of silver (Ag) and vanadium (V) ions were quantified by inductively coupled plasma mass spectrometry after 30 days. Kruskal-Wallis and Dunn’s test were applied (α = 0.05). The HGF viability was inversely proportional to the incubation time. Both incorporation techniques and the negative and positive control groups presented significant statistical differences (p 0.05), except the vacuum spatulation group with 5% of AgVO3 that showed greater viability than the negative control (p=0.013) in 24 hours. The release of Ag and V ions was proportional to the concentration of AgVO3 The 5% group presented a significant difference compared to the other groups (p<0.05). In conclusion, the acrylic resin with and without the AgVO3 incorporation had a small cytotoxic potential for HGF in 24 hours, with a lower viability in longer contact times; the release of Ag and V ions was proportional to the concentration of AgVO3, not influencing cell viability.
