Prevalence of enamel pearls in teeth from a human teeth bank.

Enamel pearls are anatomical structures that can bring about clinical implications if associated with the retention of plaque, in turn resulting in periodontal disease. In an attempt to avoid periodontal disease, the removal and treatment of these enamel pearls, may be a necessity in some circumstances. A total of 45,785 extracted teeth from a human teeth bank were analyzed for the presence of enamel pearls. The most prevalent anatomical location of enamel pearls was the permanent maxillary first and second molar region. An association between the prevalence of enamel pearls and dental class (P < 0.001) was observed, most frequently in the maxillary molars. In the maxillary molars, the most prevalent anatomical location of enamel pearls in the first and second molars was the furcation between the distobuccal and palatal roots. Enamel pearls are a common observation in molars in general, but are most commonly found in maxillary molars.
