What is the main purpose of using chlorhexidine in caries management?

The main purpose of using chlorhexidine in caries management is to reduce oral flora. Chlorhexidine is an antimicrobial agent that is effective against a wide range of bacteria, particularly the pathogenic strains associated with dental caries and periodontal disease. By significantly reducing the levels of oral bacteria, chlorhexidine helps to control biofilm formation and decrease the incidence of carious lesions.

Utilizing chlorhexidine in this manner is particularly beneficial in situations where patients may be at increased risk for caries, such as those with poor oral hygiene or reduced salivary flow. Increased reduction of harmful bacteria translates to a lower likelihood of plaque accumulation and subsequently a decreased risk of caries development.

While remineralization of enamel is a key goal in caries management, chlorhexidine itself does not aid directly in this process. Similarly, although chlorhexidine can have protective effects, it does not provide a physical seal to teeth, nor does it directly enhance bonding in restorative procedures. Thus, its primary role in managing carious lesions is attributed to its ability to lower the levels of harmful microorganisms in the oral cavity.
