Question:
Core built up on a molar tooth should preferably be done with a chemically cured composite as:

Options:
A. Light cure resin lacks sufficient strength for a core
B. Core made with a light cure resin would be too opaque and esthetically unacceptable
C. core made with a light cure resin would be too brittle and would fracture easily
D. Its lower viscosity allows free flow of resin also around pins and post'

[2025-10-01T23:54:27.187499] [PI reasoning] **Evaluating core buildup materials**

I'm not easily finding search results specifically about core buildup viscosity. Thinking back, self-cured composite core materials usually have low viscosity, allowing them to adapt to various areas. They do cure through polymerization shrinkage, but it’s manageable. I see that option D talks about lower viscosity permitting resin flow around pins and posts, which makes sense. Self-cured composites often come in flowable forms, making them suitable for core preparation. So, option D seems to be the right choice based on this reasoning.
