The ameloblastoma is the most common epithelial odontogenic tumour and occurs in the 20 to 40-year-old age group. Ameroblastoma has occasionally been reported in children but under 6-year-old is extremely rear.
A case of ameloblastoma in the left mandibular region of a 4-year-old boy treated with cryotherapy is presented. Removal of tumour mass left only a thin shell of bone, which was then devitalized by freezing. Fracture was not evident. Bone healing was rapid and 4 months were needed for almost complete repair.
There is no sign of reccurent disease after 5 years of observation.
