Abstract:
Aim: to assess how intraoperative prognostic variables (Treatment session, apical preparation size, Root canal filling length, Obstruction, Type of irrigant, Acute flare up) affect the outcome of the initial endodontic therapy. Methodology: Out of 109 treated patients, 91 had completed medical and dental data. A total of 146 received endodontic treatment with 408 Canals. All procedures were carried out in 2018 and 2019, in a private dental clinic in Sirte, Libya. The criteria of the European Society of Endodontology were used to assess the treatment outcome. The level of significance was set at p-value < 0.05%. Results: three factors, namely, the Apical preparation size (Chi-square = 49.7, p-value = 0.0001), the type of irrigant (Chi-square = 18.7, p-value = 0.001) and the root filling extension (Chi-square = 15.6, p-value = 0.016) were found to have a significant effect on the success rate at < 0.05 level of significance. Conclusion: Quantitative results lead to the conclusion that three intraoperative factors, namely, the apical preparation size, the type of irrigant and the length of root filling were found to have a significant effect on the success rate of root canal treatment.
