title: Plaque inhibition by sustained release of chlorhexidine from removable appliances.
abstract: We studied the effectiveness of a sustained-release delivery system for chlorhexidine in plaque prevention. A clinical trial in a group of eight students wearing orthodontic appliances coated by ethyl cellulose polymer containing the drug demonstrated that plaque accumulation was decreased for a period of four days. All oral procedures had been withdrawn during the clinical study. No side-effects of chlorhexidine, such as tooth staining and unpleasant taste, were observed.
