title: Age Related Prevalence of Pre-Eruptive Intracoronal Radiolucent Defects in the Permanent Dentition.
abstract: OBJECTIVE
  The present study aimed to determine if the prevalence of pre-eruptive intracoronal radiolucent defects is higher for young age groups, in which there are more unerupted teeth.
  
  
  METHODS
  A retrospective study of panoramic and bitewing radiographs was conducted. An inclusion criterion was the presence of un-erupted permanent teeth with a formed and clearly visible crown. Age groups were: young (6-8 years), intermediate (9-12 years) and adults (13-53 years). Significance level was set at p≤0.05.
  
  
  RESULTS
  Thirteen (3.9%) pre-eruptive lesions were detected in 335 records. No lesions were found in the young group (7.4%), in the intermediate and adult age groups six and seven lesions were found, respectively. In most cases the pre-eruptive lesion was found in a third molar.
  
  
  CONCLUSIONS
  The prevalence of pre-eruptive intracoronal lesions was not higher for young age groups. The prevalence of pre-eruptive intra coronal radiolucent lesions is 3.9%, irrespective of age.
