What is the purpose of irrigation and cleansing during root canal treatment?

  1. To fill the tooth with a temporary material

  2. To remove tissue dust and debris

  3. To apply a protective coating

  4. To seal the tooth from bacteria

The correct answer is: To remove tissue dust and debris

The primary purpose of irrigation and cleansing during root canal treatment is to remove tissue dust and debris. This process is crucial because, during the procedure, infected or necrotic pulp tissue needs to be cleared from the canal system to facilitate effective decontamination and prepare the space for filling. Irrigation solutions, such as sodium hypochlorite or EDTA, help dissolve organic material and flush out debris, making the canal cleaner and minimizing the risk of reinfection. An effective cleansing process contributes significantly to the overall success of the treatment by ensuring that the canal is free of contaminants that could lead to complications post-treatment. Removing tissue and debris is an essential step in establishing an environment that allows for proper sealing and healing.
