Chlorhexidine is effective in controlling dental caries in high-risk patients. Which statement is true regarding its protocol?

Chlorhexidine is indeed recognized for its effectiveness in controlling dental caries, particularly in high-risk patients. Its antimicrobial properties help to reduce the levels of cariogenic bacteria in the oral cavity, thereby playing a significant role in caries prevention. This makes the first statement true.

In dental protocols involving chlorhexidine, it's commonly recommended for use as a rinse or gel, especially in patients who are identified as being at high risk for caries due to a variety of factors such as poor oral hygiene, high levels of plaque, or a history of dental caries.

The accuracy of the second statement is critical for confirming the overall truth of the claims made about chlorhexidine's usage. Since the answer indicates that the first statement is true and the second is false, it highlights a misunderstanding of the common guidelines surrounding chlorhexidine's application. In standard practice, both statements typically align with the clinical evidence supporting the use of chlorhexidine in caries management for heightened-risk populations, thus aligning with option B rather than A, if both statements were indeed indicating beneficial uses of chlorhexidine.

Overall, chlorhexidine's role in caries prevention, specifically in high-risk patients, is significant and should be properly understood within the wider context of
