Question

Quizplus · Accepted Answer

High-strength bases placed in a thickness of 0.75 mm or greater provide protection from the thermal conduction of metal restorations.Cements used as bases are mixed to secondary consistency-a thick putty-like consistency that is condensable and can be rolled into a ball or rope.When the cavity preparation is so deep that there is 2 mm or less of remaining dentin over the pulp,many clinicians will choose to provide mechanical support for the restoration by first placing a cement base.
