Objectives: This study aimed to evaluate the effects of different irrigation systems on the removal of intracanal medicament used in regenerative endodontic treatment. Materials and Methods: Following standardized preparation to obtain an immature tooth model, modified triple antibiotic paste (mTAP) consisting of metronidazole, ciprofloxacin and clindamycin was applied to the root canals of single-rooted human maxillar teeth and waited for three weeks. A total of 50 teeth with standardized preparation and intracanal medicament were randomly divided into five groups according to the irrigation method to be applied (n=10); Group 1: Conventional Syringe Irrigation (CSI), Group 2: Passive Ultrasonic Irrigation (PUI), Group 3: EndoActivator (EA), Group 4: EndoVac (EV) Group 5: Nd:YAG laser (LSR). Following the removal of the mTAP with different irrigation systems, the teeth were divided along their bukko-lingual axis. The impact roots were examined under the stereomicroscope with the 4-grade scoring scale for the presence of residual intracanal medicaments. Scores for coronal, middle and apical regions of each root were recorded. Results: In terms of total scores, PUI group showed higher intracanal medicament removal efficacy compared to the other groups (p<0.05). In the intra-group comparison of the root canal third, less intracanal medicament was found in the apical third (p <0.05). The highest intracanal medicament removal efficacy was found in PUI and LSR groups in the coronal third, PUI group in the middle third, and PUI and EV groups in the apical third (p<0.05). Conclusions: Intracanal medicament removal scores were significantly associated with irrigation system. PUI showed statistically significantly higher intracanal medicament removal efficiency than other irrigation methods. While there was no difference between the coronal and middle thirds, statistically significantly less intracanal medicament removal was found in the apical third compared to the other regions.
