Cf. Cox et S. Suzuki, REEVALUATING PULP PROTECTION - CALCIUM HYDROXIDE LINERS VS COHESIVE HYBRIDIZATION, The Journal of the American Dental Association, 125(7), 1994, pp. 823-831
Certain clinical and biological studies have reported that prepared de
ntin and the underlying pulp must be Protected with a calcium hydroxid
e base and liners that supposedly impart biological and structural int
egrity to tissues. Since the mid-1950s, dentists have relied on a numb
er 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.
