Bacterial Contamination of Equine Dentistry Equipment—Effect of Cleaning and Disinfection

Equine dentistry has developed immensely and human dental equipment, such as handpieces, are often used. Measures to avoid the spread of infectious microorganisms are important, but this is challenging since handpieces are difficult to decontaminate. Thus, it is necessary to develop effective IPC me...
