What medicine does root canal therapy seal? Is it okay to seal iodoform?

Hello! Root canal therapy varies according to the condition of dental diseases. Not that this is good, you can seal this. If pulpitis can block CP and periapical periodontitis, if there is not much exudation, FC can be blocked, and if there is more exudation, FC iodine can be blocked. Mainly good absorbability and exudation. I haven't seen it for a long time, and what I said is not very professional, for your reference.
