Which material is used to fill root canals in the described endodontic case?

• A. Calcium hydroxide
• B. Gutta-percha
• C. Silver points and cement
• D. Zinc oxide eugenol

Answer: (C)

Filling root canals requires a material that creates a dense, hermetic seal after the canals have been cleaned and shaped to prevent reinfection. In this described case, the canal is obturated with silver points and cement. The silver points occupy and fill the canal space, while the cement surrounds them and bonds to the dentin walls to seal micro-voids and prevent leakage. Calcium hydroxide is used as an intracanal medicament, not as the final filling material. Gutta-percha with sealer is the modern standard for obturation, but this case specifies silver points with cement. Zinc oxide eugenol may act as a cement/sealer, but the described method relies on the combination of silver points with cement for obturation.
