Re-evaluating pulp protection: calcium hydroxide liners vs. cohesive hybridization.

Certain clinical and biological studies have reported that prepared dentin and the underlying pulp must be protected with a calcium hydroxide base and liners that supposedly impart biological and structural integrity to tissues. Since the mid-1950s, dentists have relied on a number of calcium hydroxide medicaments for this goal. But recent studies imply that clinicians need to re-evaluate the generous use of certain calcium hydroxide medicaments under restorations.
