How should you explain to the patient what sodium hypochlorite is?

• A. "disinfectant rinse"
• B. "bleach"
• C. "antibiotic solution"
• D. "filler material"

Answer: (A)

During root canal treatment, sodium hypochlorite is used as an irrigant to disinfect the canal and remove organic tissue. Describing it as a disinfectant rinse communicates its purpose clearly and reassuringly, focusing on cleaning and killing bacteria. Calling it a “bleach” can sound alarming, and it isn’t an antibiotic solution or a filler material. In practice, it’s used in controlled, diluted amounts and flushed out as the canal is prepared for sealing.
