Cold Atmospheric Plasma is an ionized gas that has recently been extensively studied by researchers as a possible therapy in dentistry and oncology. Several different gases can be used to produce Cold Atmospheric Plasma such as Helium, Argon, Nitrogen, Heliox, and air. There are many methods of production by which cold atmospheric plasma is created. Each unique method can be used in different biomedical areas. In dentistry, researchers have mostly investigated the antimicrobial effects produced by plasma as a means to remove dental biofilms and eradicate oral pathogens. It has been shown that reactive oxidative species, charged particles, and UV photons play the main role. Cold Atmospheric Plasma has also found a minor, but important role in tooth whitening and composite restoration. Furthermore, it has been demonstrated that Cold Atmospheric Plasma induces apoptosis, necrosis, cell detachment, and senescence by disrupting the S phase of cell replication in tumor cells. This unique finding opens up its potential therapy in oncology.
冷大气等离子体是一种电离气体,最近研究人员对其进行了广泛研究,认为它可能用于牙科和肿瘤学治疗。几种不同的气体可用于产生冷大气等离子体,如氦气、氩气、氮气、氦氧混合气和空气。产生冷大气等离子体有许多方法。每种独特的方法可用于不同的生物医学领域。在牙科领域,研究人员主要研究了等离子体产生的抗菌作用,以此作为去除牙菌斑和根除口腔病原体的一种手段。研究表明,活性氧化物质、带电粒子和紫外线光子起主要作用。冷大气等离子体在牙齿美白和复合修复中也发挥了次要但重要的作用。此外,已经证明冷大气等离子体通过破坏肿瘤细胞中细胞复制的S期来诱导细胞凋亡、坏死、细胞脱离和衰老。这一独特发现为其在肿瘤学中的潜在治疗开辟了道路。
