Plasma technologies are mostly used in dentistry; our work focuses on scopes and plasma applications dentistry. We will directly deliberate about liquid, solid, gas only without sophisticated the fourth state (Plasma), which is most abundant important considered new technology dentistry that may create a revolution this field as painless free all dental fields. The study results showed cold atm...

Cold atmospheric pressure sterilization is one of the nominated and efficient techniques to prevent spread diseases. Reactive species such as O OH other radicals play a major role in mechanism plasma sterilization. Therefore, this work, oxygen was mixed with different parentage from (0.2 1.2%) argon enhance generation reactive increase efficacy. The emission spectra jet radicle line intensities...

There are three major multi-electron reactions in nature: nitrogen fixation by bacteria, water oxidation photosynthesis, and oxygen reduction during respiration. Here we found that a cold atmospheric pressure He-plasma jet (CAPPJ) can oxidize N2 to HNO3 HNO2 at low temperature the plasma-air/water interface. Redox induced plasma occur not only plasma/air plasma/water interfaces, but also volume...

Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...

Sterilization is defined as any process that effectively kills or eliminates almost all microorganisms like fungi, bacteria, viruses, spore forms. There are many different sterilization methods depending on the purpose of the sterilization and the material that will be sterilized. The choice of the sterilization method alters depending on materials and devices for giving no harm. These steriliz...
