Which chemical has been linked to hypersensitivity reactions in patients and staff?

Chlorhexidine is an antiseptic agent commonly used for its antimicrobial properties in dental and medical settings. While it is effective in preventing infections, it is also known to cause hypersensitivity reactions in some individuals. These reactions can occur in both patients and dental staff who may be exposed to it during various procedures or routine practices, such as instrument sterilization or dental cleanings.

Hypersensitivity to chlorhexidine can manifest as allergic reactions that may include skin rashes, itching, or more severe responses. This sensitivity can arise from previous exposures, leading to sensitization and subsequent reactions. Understanding the potential for such adverse reactions is crucial for dental professionals to ensure patient safety and create a safe working environment for staff.

It is important for practitioners to be aware of the signs of hypersensitivity and take appropriate precautions, such as discussing possible allergies with patients and being prepared to manage any reactions that may occur.
