What is the primary purpose of gutta percha during the obturation process?

The primary purpose of gutta percha during the obturation process is to fill the root canals. After a root canal treatment, the objective is to thoroughly seal the cleaned and shaped canal space to prevent the reinfection of the tooth. Gutta percha is a biocompatible, thermoplastic material that can be easily manipulated to fill the irregularities of the canal system. When heated, it can be softened, allowing for better adaptation to the canal walls, which helps achieve a complete seal. This sealing is critical for long-term success in endodontic treatments, as it protects the periapical tissues from bacteria and toxins.

While disinfection of the canal and promoting pulp healing are important aspects of root canal therapy, the specific role of gutta percha is focused on the obturation process—ensuring that the canal is adequately filled and sealed. Using gutta percha effectively contributes to the overall success of the procedure and supports the dental restorative goals.
