Actually, those two diseases are caused by bacteria (facultative anaerobes and obligate anaerobes). Chemical drug (such...
To investigate the tooth bleaching effect of a low concentration hydrogen peroxide assisted by a nonthermal plasma, extracted human teeth were treated by a nonthermal plasma in the presence of varying concentrations of hydrogen peroxide gel. The results showed that combining plasma treatment with a low concentration hydrogen peroxide (6%) achieved a superior bleaching effect...
Department of Applied Science and Technology and Center for Microplasma Science and Technology, Saint Peter's College, New Jersey, USA, 07306 In dental clinics, caries is one of the highest incidence diseases in human, and Streptococcus mutans (S. mutans) is the most contributing cariogenic bacteria in oral environment.

Electron spin resonance (ESR) spectrometry is the most direct and sensitive method for detecting certain reactive oxygen species (ROS)1. By ESR diagnosis, plasma-water reactions can be elucidated, which is meaningful for guiding its clinical application.
Summary form only given. Dermatophytes are the most common aetiological agents, which invade into keratinized tissues (skin, hair, nails) of humans and animals causing dermatophytosis (also known as ringworm or tinea). Swimming pools, fitness centers, barber shops, beauty parlors, saunas and steam baths are common places to pick up superficial fungal infections. Mycotic infections have become more...
