Abstract
Objective: This study was designed to evaluate postoperative pain after endodontic retreatment. Material and Methods: Asymptomatic, multi-rooted molar & premolar teeth requiring retreatment with 2–5 mm periapical lesions were included. Seventy-eight teeth were randomly placed in four groups (n=20): single-visit (control, group 1), Ledermix (group 2), metronidazole, ciprofloxacin, minocycline mixture (group 3), calcium hydroxide (group 4). The postoperative pain was recorded using a VAS at 6, 12, 24, and 48 h after retreatment. Statistical evaluation was performed using Two-Way Repeated Measures ANOVA and Tukey test. Results: Mild pain occurred in 67.5%, moderate in 30%, and flare-ups in 2.5%, and there was a significant difference between the groups (p<0.01). Significantly lower postoperative pain was observed in TAP and CaOH2 groups(p<0.05). In the 6, 12, and 24 h intervals, there was a significant difference in the pain levels (p<0.05). Conclusion: TAP and CaOH2 are effective for reducing postoperative pain after retreatment.KeywordsIntracanal medicaments; Multiple-visit; Postoperative pain; Retreatment; Single-visit.
Highlights
Postoperative pain is defined as any pain that occurs after root canal therapy [1]
Three patients who did not return for further appointments and/or forgot to fill out the Heft-Parker visual analogue scale (VAS) forms were excluded from this research
Mild pain occurred in 67.5%, moderate in 30%, and the overall incidence of flare-ups was relatively low at 2.5% of the cases in all of the groups. The aim of this clinical study was to compare the influence of different intracanal medicaments and single-visit root canal treatments on postoperative pain after retreatment cases
Summary
Postoperative pain is defined as any pain that occurs after root canal therapy [1].Endodontic pain has been the main motive for patient consultations following treatment, and it affects patient comfort. Of patients after root canal therapy [1] It can be associated with inflammation in the periradicular tissues, and it is believed that the most important reason for endodontic treatment failure is microorganisms in the apical third of the root canal that survive after endodontic procedures [2]. The elimination of these microorganisms is very important for the success of endodontic therapy and reducing postoperative pain, especially in retreated infected root canals [3]. Because of its high-pH and antibacterial activity, CaOH 2 is still commonly used as a root canal dressing material in multiple-visit root canal treatments [7]
