Chlorhexidine is particularly effective against which type of microorganism?

Chlorhexidine is particularly effective against bacteria, making it a valuable antiseptic and disinfectant in dental and healthcare settings. It works by disrupting the cell membranes of bacterial cells, leading to cell lysis and death. This broad-spectrum activity includes effectiveness against both Gram-positive and Gram-negative bacteria, which are commonly associated with various infections in dental practices.

In addition to its antibacterial properties, chlorhexidine exhibits some residual antimicrobial action, which helps maintain a clean environment after initial application. This characteristic is particularly beneficial in oral hygiene products, surgical scrubs, and antiseptic mouthwashes used to reduce oral bacteria and promote overall oral health. While chlorhexidine may have some limited activity against viruses and fungi, its primary efficacy is directed toward bacterial pathogens. Its role in preventing infections and managing dental diseases underscores why it is viewed as superior against bacterial microorganisms.
