ABSTRACT
This review considers the main agents which have been used as anti-plaque and anti-gingivitis agents in mouthwashes and other vehicles to inhibit the growth of supragingival plaque. The agents are classified into first generation, second generation and third generation agents. Bisguanide antiseptics, hexetidine, povidone iodine, triclosan, delmopinol, salifluor, metal ions, sanguinarine, propolis and oxygenating agents are included. The anti-plaque and antigingivitis properties of these agents are considered along with their substantivity, safety and possible clinical usefulness. A number of product forms are available to deliver anti-plaque agents (i.e., mouthrinses, dentrifices, aqueous gels, chewing gum and lozenges) and should facilitate optimal bioavailability at the site of action and patient compliance.
