Enamel Pearl
A small, spherical nodule of ectopic enamel deposited on the root surface of a tooth, typically at the furcation area, considered a developmental anomaly of potential clinical and editorial significance.
Full Definition
Enamel pearls are discrete, rounded deposits of enamel—sometimes containing dentine or pulp—found on the root surfaces of teeth, most frequently at the furcation of maxillary molars. They arise from aberrant activity of Hertwig's epithelial root sheath during root development. Clinically, enamel pearls may predispose to localised periodontal defects. In oral pathology reports, the term must be distinguished from Epstein pearls, which are keratin-filled cysts of the neonatal palate. Editors working on pediatric dentistry or oral pathology manuscripts should be alert to this confusable pair.
Usage
Usage note: Do not confuse with Epstein pearls (neonatal palatal cysts) or with Bohn's nodules; context is key for correct usage.
