“…These findings are in accordance with previous study, which have demonstrated that failure of endodontic therapy can occur regardless of gender and age [9]. However, a higher age group was observed in the cases of extraction (51-60 years) when compared to cases of retreatment (41-50 years) of endodontically treated teeth.…”

“…Althoug et al the reasons related to periodontal diseases were 5.8 times more important with smokers than with non-smokers [11], Touré et al [12] have showed that smoking status did not show any differences when compared with reasons for extraction of endodontically treated teeth. Furthermore, the amount of smoke and the total time of consumption by the patient cannot be determined and may influence these divergent results [9].…”

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.Key words: Endodontically treated teeth; Retreatment; Extraction Análise das razões para retratamento e extração de dentes tratados endodonticamente: um estudo transversal RESUMO INTRODUÇÃO: Analisar razões relacionadas com retratamento e extração de dentes tratados endodonticamente. METODOLOGIA: Os dados foram coletados consecutivamente durante 12 meses a partir de pacientes que tiveram indicação para retratamento ou extração de dentes tratados endodonticamente após uma consulta inicial. Os pacientes foram agendados para uma nova consulta e a necessidade de reatratamento ou extração foi confirmada por três examinadores previamente calibrados. Em seguida, um formulário clínico foi preenchido, incluindo informações sobre o paciente e o dente acometido, presença de lesão periapical, razões para retratamento ou extração e a opção de tratatamento. As variáveis mencionadas foram computadas e descritas como valor absoluto e percentual. RESULTADOS: Obturação inadequada foi a razão mais frequente (40.5%) para realizar o retratamento endodôntico; o retratamento convencional não-cirúrgico foi a mais frequente opção de tratamento nesses casos (95%). Falha ou fratura de restaurações definitivas (coroas protéticas) foi a razão mais frequente (30%) para realizar a extração de dentes tratados endodonticamente; a reabilitação protética foi a mais frequente opção de tratamento nesses casos (78%). CONCLUSÃO: Obturação inadequada e falha ou fratura em restaurações definitivas associadas com lesão periapical devem ser levados em consideração durante o processo de tom...

“…These results are in agreement with earlier findings that teeth with apical periodontitis have a significantly lower success rate than those without such lesions. [5][6][7][8][9][10] Stepwise logistic regression analysis revealed that preoperative apical radiolucency was important for predicting treatment failure, with an OR of 3.6 (p = 0.011): in other words, teeth with diseased periapical status have a 3.6 times greater risk of failure than those with a normal periapex. This OR is similar to the values reported in the Toronto studies, 8,9 but lower than that found in other studies.…”

“…Further, the preoperative presence versus absence of periapical radiolucency is a major indicator of postoperative healing or failure. [1][2][3][4][5][6][7][8][9][10] To assess the treatment outcome and elucidate the effect of specific factors on the outcome, randomized controlled trials are graded higher scores for the strength of level of evidence. 11 Treatment techniques and instruments have been effectively evaluated in randomized controlled studies.…”

“…[12][13][14][15][16] However, the special prospective cohort study models have been proposed to assess the outcome of endodontic treatment and elucidate the effect of various preoperative factors on the outcome in several studies. [7][8][9][10] A conspicuous aspect of these studies was the identified inception cohort, standardized treatment procedures, and data recording at the start of the study.…”

Objectives: This study aimed to assess prospectively the clinical outcome of nonsurgical endodontic treatment and identify patient-and tooth-related factors, rather than treatment-related factors, that were the best predictors of this outcome. Materials and Methods: The inception cohort comprised 441 teeth (320 patients) and 175 teeth (123 patients) were followed up for 1-2 years. Age, gender, presence of medical disease, number of canals, previous endodontic treatment, presence of sensitivity and pain, pulp vitality, swelling or sinus tract of pulpal origin on the gingiva, periapical radiolucency and tendency of unilateral bite on the affected tooth were recorded at treatment start. Results: The outcome was classified on the basis of periapical radiolucency as healed or non healed. The overall healed rate in these cases, including nonsurgical retreatment, was 81.1%. Four tooth-related factors had a negative impact in the bivariate analysis: previous endodontic treatment, necrotic pulp, preoperative gingival swelling or sinus tract of pulpal origin, and preoperative periapical radiolucency. Stepwise logistic regression analysis including patient-, tooth-related factors and level of the root canal filling as a treatment-related factor showed that preoperative gingival lesion (odds ratio [OR]: 4.4; p = 0.005), preoperative periapical radiolucency (OR: 3.6; p = 0.011), and ≤ 1-2 mm under root filling length (OR: 9.6; p = 0.012) were significant predictors of failure. Conclusions: A preoperative gingival lesion of pulpal origin can influence the outcome of nonsurgical endodontic treatment in addition to preoperative periapical radiolucency.
