What is the principal component of gutta percha used in obturation materials?

• A. Gutta-Percha
• B. Zinc Oxide
• C. Heavy Metal Salts
• D. Waxes

Answer: (A)

The main idea here is that the gutta-percha obturation material is built around the gutta-percha polymer itself. Gutta-percha provides the essential plasticity and thermoplastic behavior that allows the cone to soften with heat, adapt to canal walls, and then harden to seal. Other ingredients—such as zinc oxide, waxes, and resins—are added to modify handling, stiffness, and radiopacity, but they are not the primary component. So the principal constituent of gutta-percha obturation material is the gutta-percha polymer itself.
