title: Radiographic evidence of enamel pearls in jordanian dental patients.
abstract: OBJECTIVE
  An "enamel pearl" is an ectopic globule of enamel that is adherent to the tooth root surface. Such an anomaly may facilitate the progression of periodontal breakdown. Information on the prevalence of enamel pearls is sparse, and ethnic variations are thought to occur. Our objective was to assess the prevalence of enamel pearls in a group of Jordanian dental patients.
  
  
  METHODS
  A random sample of 819 dental records were selected, and a total of 1032 periapical radiographs were interpreted for the presence of enamel pearls.
  
  
  RESULTS
  Enamel pearls were detected in 4.76% of the subjects and on 1.6% of the molars. No significant difference between sexes was observed. First molar teeth were the most commonly affected, whereas the third molars were the least affected with the condition.
  
  
  CONCLUSIONS
  Enamel pearls are not uncommon among Jordanian dental patients, and their early detection could be important in prevention of periodontal disease.
