21 Year Recall: Internal Perforation Repair with Amalgam

Long-term recall of internal perforation repair with amalgam

Patient: 38 year-old male in excellent health (1994)

Chief Complaint: Severe tooth ache

Dental History: The patient presented to the author in 1994 having had previous endodontic therapy on the maxillary right first molar (tooth #3) in 1990. Severe tooth pain had developed localized to the tooth 1 ½ weeks prior to the author examining the patient at which time the patient’s dentist had attempted endodontic retreatment. The attempted nonsurgical endodontic retreatment procedure failed to relieve the patient’s pain and the general dentist had performed an emergency surgical flap procedure. Antibiotics and narcotic analgesics had been prescribed and the patient was referred for endodontic consultation (1994)
