| Sumario: | OBJECTIVE: Was to analyze the reasons related to retreatment and extraction of endodontically treated teeth.METHODS: Data were collected consecutively during a 12-month period from data of patients who had indication for root canal retreatment or extraction of endodontically treated teeth after an initial visit. The patients were scheduled for a new consultation and the need for root canal retreatment or extraction was confirmed by three previously calibrated examiners. After that, a clinical form was completed, including data about the patient and tooth, presence of apical radiolucency, reasons for root canal retreatment or extraction, and the treatment option. The aforementioned variables related to the patients and the teeth were computed and are given as their absolute value and percentage.RESULTS: Inadequate filling was the most frequent reason (40.5%) to perform root canal retreatment; non-surgical root canal retreatment was the most frequent treatment option (95%). Failure or fracture on definitive restoration (prosthetic crown) was the most frequent reason (30%) to perform extraction of endodontically treated teeth; tooth extraction with prosthetic rehabilitation was the most frequent treatment option (78%).CONCLUSION: Inadequate filling and failure or fracture on definitive restoration associated with apical radiolucency should be taken into account during the decision-making process regarding endodontically treated teeth with questionable prognosis. |
