Periodontal diseases are the major cause of tooth mortality in many industrialized countries and most developing nations. The significance of microorganisms in the development of virtually all types of periodontal disease is indisputable. This book is an encyclopedic collection of data from scientific papers and textbooks that form a sound basis for a thorough understanding of the antibiotics and antiseptics used in periodontal therapy. The prophylactic, systemic, and topical uses of antibiotics are discussed in detail, identifying the indications, advantages, disadvantages, and efficacy of each approach and regimen. The use of antiseptics is also carefully examined, with particular attention to the merits of different delivery methods and oral hygiene agents. The closing chapter addresses the role of non-steroidal anti-inflammatory drugs. This book will be of value to undergraduate and postgraduate dental students, dental hygienists, dental practitioners, and other associated professionals.
