Plaque control is defined as the removal of microbial plaque and prevention of its accumulation on the tooth surface and adjacent gingival tissues to prevent calculus formation. Plaque control is of two types - Mechanical plaque control and Chemical plaque control. The level of mechanical plaque control achieved at individual level decreases on a time gradient. Hence a chemical plaque has to be addressed on individual level on daily basis for proper maintenance of oral health. 0.2% chlorhexidine (CHX) solution was the first clinically effective mouth rinse that inhibited supragingival plaque formation and thus the development of chronic gingivitis and caries. Due to its broad-spectrum antibacterial effect encompassing gram-positive as well as gram-negative bacteria, yeasts, dermaphytes and some lipophilic viruses, and the prolonged substantivity, chlorhexidine is still recognized as the ‘‘gold standard’’ for chemical plaque control.
Key words: Chlorhexidine, supragingival plaque.
