This case will appear in a manuscript in a future issue of Clinicians Brief.  I saw this Irish Setter one month following excision of generalized gingival hyperplasia . The veterinarian used a radiosurgical unit to excise the tissue.   Severe bone and gingival necrosis with tooth mobility and gingival recession were present secondary to tissue hyperthermia from the radiosurgical unit..  Multiple teeth required extraction.  Non-mobile teeth may require extraction and follow up radiography and evaluation have been set for September.
