Understanding C-Factor in Composite Resin Polymerization
Understanding C-Factor in Composite Resin Polymerization Write a short note on C-Factor. Answer: The magnitude of stress depends on the composition of the composite and its ability to flow before gelation occurs. This is influenced by the shape of the cavity and can be overcome by the way the dentist places the material into the cavity. This has been termed a configuration … [Read more...] about Understanding C-Factor in Composite Resin Polymerization
