The effects of exposure to O- and HOCl-nanobubble water on human salivary microbiota.

Nanobubbles of gas remain dissolved in water for longer periods than ordinary bubbles, and exhibit unique physicochemical and biological properties. As a result, nanobubble water (NBW) is finding widespread use many applications, such as cleaning in the industry and purification of lake water. The ozone NBW (O-NBW), in particular, has been used in clinical dentistry; however, it has several disadvantages, including the instability of ozone, which is spontaneously converted to molecular oxygen (O to O), and its broad range of antibacterial activity, which can disrupt the oral microbiota.

Association of personality traits with dental visit procrastination by Japanese university students.
