The effects of irrigation solution temperature on modified triple antibiotic paste removal from root canals using XP-Endo Finisher

Purpose: This study aimed to study the effects of irrigation solution temperature on the removal of intracanal medicament from root canals using XP-Endo Finisher (XPF).
Methods: This study used 72 extracted, single-root maxillary central human teeth prepared with an R40 Reciproc file, and the roots were separated into two parts lengthwise. In the apical and coronal regions, two grooves of 3 mm length were opened. Afterward, modified triple antibiotic paste (mTAP) was
placed inside these canals and the roots were joined. Then, they were randomly divided into 6 groups: Group 1: conventional syringe irrigation (CSI) and 21 °C sodium hypochlorite (NaOCl), Group 2: XPF and 21 °C NaOCl, Group 3: CSI and 37 °C NaOCl, Group 4: XPF and 37 °C NaOCl, Group 5: CSI and 50 °C NaOCl, Group 6: XPF and 50 °C NaOCl.
Results: A significant difference was observed in the apical region (p< 0.05). Groups 2, 4, and 6 showed significantly better results in removing mTAP than Groups 1 and 3 (p< 0.05).
Conclusion: It has been observed that using NaOCl solution at different temperatures does not affect the efficiency of XPF in removing mTAP. However, the solution increased the effectiveness of the CSI technique.
