Nonsurgical Versus Surgical Endodontic Retreatment on Teeth With Posts?

Patient: 65 year-old female with Hashimoto’s Disease and managed hypercholesterolemia

Chief Complaint: swelling on gums

Dental History: The patient reported a past history of root canal treatment (not recent) and a new crown on the maxillary left second bicuspid (less than a year). She started to notice some swelling associated with the area 3 weeks before the endodontic consultation.

Significant Findings (Tooth #13): a fluctuant buccal mass was noted opposite the said tooth which yielded slight discomfort when palpated. A periapical radiograph revealed a large periapical radiolucency and previous root canal treatment. The less radiopaque column of material in the coronal half of the root suggested a bonded fiber post. Clinical tests demonstrated Class 1 mobility, moderate percussion sensitivity, and periodontal findings within normal limits.
