Abstract:

Summary： Periodontal disease is a biofilm（dental plaque）induced disease. Plaque control is very important to prevent， arrest， or reverse the ravages of the plaque diseases. The paper reviews the methods to measure and remove the plaque. For self-care for most periodontal patients， it is the usual need to have mechanical plaque control with the ‘brush， floss， and flush’ routine， coupled with chemical methods-appropriate use of chlorhexidine or other antimicrobial agents ao as to reduce the possibility of periodontal disease.
