Correct Answer: Crown discoloration
Description: Triple antibiotic paste
Consists of metronidazole, ciprofloxacin, and minocycline in a macrogol propylene glycol ointment. It is inserted into the canal with a sterile lentulospiral and left in the canal for 2-4 weeks.
Advantages:
Very effective in elimination of intracanal microbes.
Broad spectrum action.
Easy to prepare as ingredients are easily prepared.
Disadvantages of Triple Antibiotic Paste:
Difficult to test the antimicrobial effectiveness in endodontic models due to absence of an inactivator to prevent the carryover effect.
