What is the main function of irrigation solution in endodontic treatment?

• A. Soak paper points
• B. Lubricates canal and washes out debris
• C. Dress root canal before filling
• D. Dry canal with paper points

Answer: (B)

The main function of an irrigation solution in endodontic treatment is to lubricate the canal and wash out debris. As you instrument the root canal, dentin shavings, pulp tissue, and bacteria accumulate on the walls and in irregular spaces. A lubricating irrigant reduces friction between the files and canal walls, helping instrumentation be smoother and safer, while its flushing action physically removes debris, tissue remnants, and loosely adherent material from the canal system. Some irrigants also have antimicrobial or tissue-dissolving properties, which enhance cleaning, but the core purpose during instrumentation is to keep the canal clean and piping free of debris by flushing it away and to make subsequent steps easier. Why the other ideas don’t fit as the main function: soaking paper points is not the primary goal of irrigation, drying the canal with paper points is a separate step, and dressing the root canal before filling refers to medicaments or temporary fillings rather than irrigation’s primary action of cleaning and lubricating.
