title: Oral pain due to severe pre-eruptive intracoronal resorption in permanent tooth.
abstract: BACKGROUND
  Pre-eruptive intracoronal resorption is a dental lesion located within the dentin. This defect is usually discovered incidentally on routine dental radiographs. Occasionally this process may be associated with oral pain in advanced lesions.
  
  
  METHODS
  This case report describes a 12-year-old boy whose chief complaint was a diffuse oral pain due to a severe pre-eruptive intracoronal resorption in a permanent second molar. The previous radiographs, taken at the age of nine years, showed no evidence of the lesion. After surgical exposure, a pulp-like tissue under the crown was removed and analyzed; subsequently the tooth was extracted due to extensive resorption. A follow-up of the unerupted third molar, still in formation process, allowed to see that it was favourably positioned for replacing the extracted molar.
