4. v Preface Periodontitis is defined as an inflammatory disease of the periodontium characterized by inflammation of the gingival and adjacent attachment apparatus, illustrated by loss of clinical attachment due to destruction of the periodontal ligament and loss of the adjacent supporting bone. Periodontitis represents the major cause of tooth loss in adults leading to long-term disability and increased treatment needs. It is well estab- lished that the various periodontal diseases are caused by bacterial infection. Dental plaque was defined as “matrix-enclosed bacterial populations adherent to each other and/or to surfaces or interfaces”. Dental plaque is a microbial biofilm, a diverse microbial community found on the tooth surface embedded in a matrix of polymers of bacterial and salivary origin. This complex biofilm may offer some pro- tection from the host’s immunologic mechanisms as well as chemotherapeutic agents used for treatment. It is therefore logical to do first the mechanical removal and dis- ruption of the dental plaque biofilm itself. Antimicrobial agents are used extensively in both medicine and dentistry to elimi- nate infection. These drugs are also widely used as a prophylaxis to prevent infection in the “at risk” patient. This book is a collection of data from scientific papers and textbooks found to be important for the understanding of the antibiotics and antisep- tics used in the periodontal therapy. This book is addressed to dentists, periodontologists, undergraduate and postgrad- uate dental students, dental hygienists, and other co-associated professionals. Alexandrina L. Dumitrescu
