Which broad-spectrum antimicrobial agent is added to dentifrices for its antiplaque and antigingivitis properties?

Triclosan is a broad-spectrum antimicrobial agent commonly added to dentifrices for its effective antiplaque and antigingivitis properties. It works by inhibiting the growth of bacteria that are responsible for dental plaque and gum disease. The mechanism of action involves disrupting the bacterial cell membrane and interfering with the bacterial metabolic pathways, which contributes significantly to its efficacy in maintaining oral hygiene and reducing inflammation associated with gingivitis.

Dentifrices containing triclosan have been clinically shown to reduce the levels of plaque and gingival inflammation, making it a valuable ingredient in oral care products aimed at promoting periodontal health. The incorporation of triclosan in toothpaste can lead to improved outcomes for patients susceptible to periodontal diseases, thus enhancing the overall effectiveness of daily oral hygiene practices.

In contrast, stannous fluoride primarily functions as a fluoride source that helps in remineralization and also has some antibacterial properties, but its primary focus is not on plaque control. Recaldent chewing gum, which contains casein phosphopeptides, is more oriented toward enamel remineralization and does not possess strong antimicrobial properties. Pyrophosphates are primarily included in toothpaste for their ability to prevent calculus formation rather than for their antimicrobial effects. Therefore, triclosan stands out as the
