Web:, By Arthur Goldstein, DDS Case history Mr. H presented in my office in an emer- gency situation with pain that had begun several days prior in tooth #27. The pain was no longer relieved by analgesics, and sensitivity had begun in the right sub mandibular area. Clinical examination The #27 tooth had a class IV occlusal distal amalgam restoration of long date. There did not seem to be secondary car- ies. There was no apparent decay in the tooth, which was very sensitive to light percussion. There was also sensitivity in centric occlusion, which dissuaded the patient from closing his teeth together. Radiographic examination Radiographic examination revealed a large area of internal resorbtion apical to the gingival crest (Fig. 1). Treatment Mr. H. was given three grams of amoxi- cillin and 400 grams of Spifen and in- structed to take two grams of amoxicil- lin six hours after the procedure. A right mental foramen block local anesthetic of articaine Hcl with adrena- line was given. A full-thickness periodontal flap incision to bone with a Colorado electrode and Ellman Dento-Surg™ Radiosurgical unit set to “cut” (fully rectified filtered current) was performed to gain access to the area of internal resorbtion (Figs. 2, 3). The area of resorbtion was curetted, followed by a root canal treatment with a gutta percha cone and estesone sealer (Fig. 4). The lamina dura at the apex of the root was not defined (Fig. 4). A base of ZnPo4 cement was placed over the cone in the area of the resorb- tion, followed by a well-polished macro composite filling. The periodontal flap was closed with Ethicon #5 non-resorb- able sutures (Fig. 5). The #27 tooth is seen one-week post op in Fig. 6 and one- month post op in Fig. 7. Mr. H did not wish further treatment of the #27 tooth. Figs. 2, 3 Radiosurgery provides access to area of internal resorbtion.
