Basic Guide to Infection Prevention and Control in Dentistry
Description
Reviews / Votes
"This is a reputable source of infection control and prevention protocols, and this update is necessary to maintain current guidelines on infection control. The book can be used as an additional resource for U.S.-based practices, but it may not be suitable as the sole book because some information is pertinent only to U.K. practice. The book is very thorough if used for proper practice guidelines, but more detail may be necessary based on individual practices" Maria Prassas, RDH, MEd, MOT, University of Illinois at Chicago College of Dentistry on behalf of Doody'sMore details
