INTRODUCTION: In cases of post-treatment periapical disease, retreatment may be necessary. To choose the most appropriate retreatment method, knowledge of the long-term prognosis is important. Surgical endodontic retreatment (SER) is a relevant treatment method. This study assessed changes in outcome from 1 to 6 years after surgery.
METHODS: SER was performed on teeth randomly allocated to have a MTA root-end filling (MTA group) or smoothing of the orthograde gutta-percha filling after apicectomy (GP group). Patients participating in the 1-year follow-up were reinvited for a 6-year clinical and radiographic examination. Three observers assessed treatment outcome both clinically and radiographically from the 1-year and 6-year follow-up examination.
RESULTS: At the 6-year follow-up, 39 of 52 teeth were available and examined (75% participation rate). In the MTA group, 16 of 19 teeth (86%) and in the GP group 11 of 20 teeth (55%) were assessed as successful (P = .04). In the MTA group and the GP group, 80% and 90%, respectively, of teeth assessed as successful at the 1-year follow-up remained successful. All unsuccessful teeth in the MTA group (3 teeth) were lost because of vertical root fracture.
CONCLUSIONS: The proportion of healed cases was larger in the MTA group than in the GP group at both the 1-year and 6-year follow-up. Findings indicate that a 1-year follow-up may not be sufficient in assessing the long-term outcome of surgical endodontic retreatment. With a longer follow-up, other factors not directly related to the endodontic treatment may be relevant for a successful outcome. This needs further investigation in larger patient samples.
