Root Canal Irrigation Procedure - Dental Treatment Diagram #1441081 (License: Personal Use)

This artistic medical illustration depicts the critical irrigation phase of root canal treatment, where a fine needle delivers antimicrobial solution into the cleaned root canals to remove residual bacteria and necrotic tissue. The cross-section shows inflamed periapical tissue (red), dentin (tan), pulp remnants (purple), and a rubber dam (blue grid) isolating the tooth. The syringe tip is positioned precisely within the canal system to ensure thorough debridement before obturation.

Used on dental education sites, endodontic practice pages, or patient-facing resources explaining root canal steps; matches user intent to understand treatment safety, procedure details, or post-op expectations.
