An audit of surgical retrograde root canal re-treatment outcome: Part Two.

Method Only single-rooted teeth from the anterior maxillary and mandibular sextants were included within this audit. All treatment cases included within these audit cycles were assessed, treatment-planned and treated in accordance within the guidelines set by the strict surgical protocol determined in Part One of this series. Exclusion factors from the audit were: posterior teeth, those whose treatment was abandoned due to intra-operative factors (e.g. location of root fracture) or when necessity involved deviation from the surgical protocol. It was determined that the first cycle of audit would incorporate 20 consecutive surgical retrograde root canal re-treated teeth (on some occasions, more than one tooth was treated per patient). Teeth treated by SRRCR were reviewed one year post-operatively, in accordance with recommended guidelines (4). The clinical review of cases was undertaken as follows. To determine the patients’ perception of the surgical procedure and the outcome of treatment, they were asked the following questions: 1. If they had suffered pain or swelling from the treated tooth or adjacent area? 2. If so, what were the specifics of their symptoms? 3. Were they happy with the outcome of the surgical retrograde root canal re-treatment? 4. In retrospect, would they still have had the procedure performed? To determine the outcome of the surgical procedure, the patients were subsequently examined clinically and assessed for the following: 5. Presence of sinus or vertical narrow Dental
