Patterns of enamel maturation.

abstract：:The present investigation demonstrates that direct application of a composite resin on an acid-etched, vital dentin surface is hazardous to the pulp in monkey teeth. This indicates that exposed dentin should be protected before treating the tooth with a restorative technique including acid etching. A ca(OH)2-containin...
