Enamel Pearl in Section
Occasionally a small enamel protrusion (A) is deposited on the root of a tooth - an enamel pearl. These protrusions develop when a patch of the epithelial root sheath fails to break free from the dentinal surface to form an epithelial rest. The inner dental epithelial cells differentiate into ameloblasts which proceed to deposit enamel. Enamel pearls vary from 0.3 to 2.0 mm in diameter and may be composed of enamel (B) only, enamel and dentin (C), or enamel, dentin and pulp (D). This example contains all 3 tissues.
