Nanotechnology presents a promising approach for managing chronic periodontitis, a common oral disease characterized by gum inflammation and loss of supporting bone around teeth. This study aimed to evaluate the antimicrobial efficacy of acerola-mediated silver nanoparticles (AgNPs) gel and copper oxide nanoparticles (CuONPs) gel in periodontitis patients with and without diabetes.
The antimicrobial efficacy of acerola-mediated AgNPs gel and CuONPs nanogel was assessed using the agar well diffusion technique, Minimum Inhibitory Concentration (MIC) assay, Minimum Bactericidal Concentration (MBC) analysis, time-kill curve assay, and cytoplasmic and protein leakage analysis from periodontitis patients with and without diabetes.
The study found that acerola-mediated AgNPs gel demonstrated more consistent and effective antimicrobial activity against periodontitis, with lower MIC and MBC values compared to the CuONPs gel, across all tested concentrations. These results suggest that acerola-mediated AgNPs gel may be a more effective and targeted therapeutic agent for periodontal disease management.
The findings emphasize the importance of nanoparticle gel concentration in optimizing periodontal treatment outcomes. Acerola-mediated AgNPs gel, with its superior efficacy and consistency in bactericidal activity, shows significant potential for periodontal therapy.
Innovative nanoparticles like copper and silver oxides exhibit antibacterial, anti-inflammatory, and antioxidant properties, making them promising agents for targeting periodontal pathogens. Acerola (Malpighia emarginata), with its high vitamin C content and antioxidant properties, is beneficial in mitigating oxidative stress associated with chronic periodontitis.
纳米技术为治疗慢性牙周炎提供了一种有前景的方法。慢性牙周炎是一种常见的口腔疾病,其特征为牙龈炎症和牙齿周围支持骨的丧失。本研究旨在评估针叶樱桃介导的银纳米颗粒(AgNPs)凝胶和氧化铜纳米颗粒(CuONPs)凝胶对患有和未患有糖尿病的牙周炎患者的抗菌效果。
采用琼脂孔扩散技术、最低抑菌浓度(MIC)测定、最低杀菌浓度(MBC)分析、时间 - 杀菌曲线测定以及对患有和未患有糖尿病的牙周炎患者进行细胞质和蛋白质渗漏分析,来评估针叶樱桃介导的AgNPs凝胶和CuONPs纳米凝胶的抗菌效果。
研究发现,在所有测试浓度下,针叶樱桃介导的AgNPs凝胶对牙周炎表现出更一致且有效的抗菌活性,与CuONPs凝胶相比,其MIC和MBC值更低。这些结果表明,针叶樱桃介导的AgNPs凝胶可能是一种更有效且有针对性的牙周疾病治疗药物。
研究结果强调了纳米颗粒凝胶浓度在优化牙周治疗效果中的重要性。针叶樱桃介导的AgNPs凝胶在杀菌活性方面具有卓越的功效和一致性,在牙周治疗中显示出巨大潜力。
像氧化铜和氧化银这样的新型纳米颗粒具有抗菌、抗炎和抗氧化特性,使其成为靶向牙周病原体的有前景的药物。针叶樱桃(Malpighia emarginata)富含维生素C且具有抗氧化特性,有助于减轻与慢性牙周炎相关的氧化应激。
