title: Oral focal mucinosis associated with cervical external root resorption: a case report.
abstract: BACKGROUND
  Oral focal mucinosis (OFM) and cervical external root resorption are both rare lesions with an unknown etiology. In this article we report on a rare occurrence of OFM associated with cervical external root resorption.
  
  
  METHODS
  A 44-year-old female patient presented with sharp pain while drinking cold beverages and a firm localized gingival overgrowth adjacent to the buccal aspect of tooth #19. An excisional biopsy of the gingival lesion was taken and a deep cavity was found in the buccal aspect of the root. The cavity was restored with an amalgam filling.
  
  
  RESULTS
  The histological findings were of a well-circumscribed lesion composed of myxomatous connective tissue, which contained numerous stellate-shaped fibroblasts. Based on the findings, a diagnosis of OFM was made.
  
  
  CONCLUSIONS
  A rare case of OFM and cervical external root resorption occurring in the same site was described. A possible link between these 2 phenomena was hypothesized.
