Cryotherapy for localized juvenile spongiotic gingival hyperplasia: preliminary findings on two cases

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. Case Report: 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. Conclusion: Cryotherapy appears to be successfully in LJSGH and well received by paediatric patients.
