[2025-10-01T20:47:09.547316] [PI reasoning] **Clarifying KRI paste composition**

I’m considering a dentistry question about KRI paste used in endodontics, likely an iodoform paste. I need to recall its composition, thinking it includes iodoform powder mixed with camphorated parachlorophenol and menthol. I believe the marketed product by Volkmann has 80% iodoform, along with camphor, parachlorophenol, and menthol. So, option A aligns best with this composition. I should verify that with a quick search for citations.
