Enamel Pearl (enameloma)

A small nodule of enamel can form on the root surface near the amelocemental junction, particulary on maxillary molars; mandibular molars are the second most frequent site (Figure 1-1). This may result from cells of Hertwing’s sheath which have become differentiated into ameloblast. It consist of a circumscribed nodule of otherwise normal enamel, occasionally with a core of dentine and rarely containing a minute horn of pulp. Small lesions may become coated with cementum.
