title: Cryotherapy for localized juvenile spongiotic gingival hyperplasia: preliminary findings on two cases.
abstract: BACKGROUND
  Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a distinct subtype of inflammatory gingival hyperplasia that shows lack of response to traditional periodontal treatment, and after surgical excision, recurrence rate of 6-16% has been reported.
  
  
  METHODS
  Two girls (11- and 9-year-old) with multifocal red patches along the maxillary and mandibular labial gingiva showed no regression of the lesions after basic periodontal treatment. Surgical excision of focal lesion in each case was performed, which showed typical features of LJSGH. In both cases, the lesions presented recurrence. Hence, cryotherapy sessions in all lesions were performed.
  
  
  CONCLUSIONS
  Cryotherapy appears to be successfully in LJSGH and well received by paediatric patients.
