“…Ozone is an unstable compound that decomposes very quickly (half‐life 40 minutes at 20°C) . It derives from ozone generators, either corona discharge technology, UV light, or electrolysis . Ozone affects the cell membrane, vital proteins, unsaturated lipids, and the intracellular enzymes of microorganisms .…”

The goal of disinfection in the dental office is to prevent the spread of infection from one patient to another and maintain the safety of the dental care providers. Prevention of cross infection has significant effect on infection control. The standard procedure of rinsing impressions under tap water immediately after removal from the mouth eliminates microorganisms along with saliva and blood. A broad search on published literature was done using the keywords impression materials, disinfection method, and sterilization of dental impression from 1980 to 2016 in Medline, Google Scholar, the internet, and textbooks. This article critically analyzes the various published methods of dental impression disinfection in dentistry.

“…The same conclusion was also applied to reaction (5d). The rate constants for reactions (6), (7), and (8) are equal to k 6 = 5.71 × 10 −34 cm 6 · molecule −2 · s −1 ,25 k 7 = 9.77 × 10 −24 cm 3 · molecule −1 · s −1 ,3 and k 8 = 8.8 × 10 −15 cm 3 · molecule −1 · s −1 ,26 respectively. They were divided by two for those reactions which can give isotopically different products (7b‐7e, 8c, 8d, 8g, 8h).…”

Oxygen scrambling is observed when a 1:1 mixture of 16O2 and 18O2 in nitrogen/helium buffer (total O2: 5–20%) is treated at atmospheric pressure in a surface discharge plasma reactor. The statistical isotope distribution (16O2/18O2/16O18O = 1:1:2) is achieved with a very low SIE (i.e., the energy per unit volume). This process, implemented by kinetic simulations, is proposed as a chemical probe for the determination of the average O‐atom density in atmospheric plasmas. It was found that, within the explored composition range (5–20% O2 in N2/He buffer), the average O‐atom density increases with SIE, while it decreases with increasing content of O2 in the gas being treated. In contrast, an opposite trend is observed for ozone production, which increases with the concentration of O2 in the treated gas. These observations are consistent with the known reaction of O‐atoms with O2 to form ozone, which, at constant total pressure, is expected to favor ozone production as the concentration of O2 is increased.

“…The temperature gradient causes a phenomenon of diffusion and convection as a result of the accompanied strong heterogeneity in the neutral gas density and pressure [12]. The fundamental role of neutral heating in the inception of gas breakdown has been shown by theoretical studies [13][14], as well as by experimental studies [15].…”
