What is the traditional root canal filling material for primary teeth?

The traditional root canal filling material for primary teeth is zinc oxide-eugenol paste. This material has been widely used in pediatric dentistry due to its favorable properties, including its biocompatibility, ease of manipulation, and sealing ability. Zinc oxide-eugenol paste is particularly advantageous because it has analgesic and antibacterial effects, which are beneficial in treating infected root canals in children's teeth.

Zinc oxide-eugenol also allows for good flow and adaption to the canal spaces, making it suitable for the often complex root anatomy of primary teeth. Its ability to set quickly and form a strong seal against bacteria and fluids makes it a preferred choice in various cases of pulp therapy in primary teeth.

In contrast, gutta percha points are primarily used in permanent teeth for root canal fillings, as they provide excellent sealing properties and are more suited for the adult dentition. Calcium hydroxide paste, while beneficial for its antibacterial properties and promoting healing, is primarily used as an intracanal medicament rather than a final filling material for root canals in primary teeth. Mineral trioxide aggregate (MTA) is also an excellent Material, especially in pulp capping and apexification, but it is typically used in cases involving permanent teeth and complex clinical scenarios.
