Aim: To evaluate the effect of cold and room-temperature normal saline as a final irrigation on post-endodontic pain and to compare the post-endodontic pain level between the different protocols.

Materials And Methods: A randomized controlled trial was conducted on 105 patients who underwent RCT and were distributed blindly and randomly into three equal groups (n = 35): Group 1, Cryotherapy group; Group 2, Room- temperature normal saline group; and Group 3, Control group. The patients were asked to fill out the VAS questionnaire and register their post-endodontic pain at 6, 24, and 48 h. One-way analysis of variance (ANOVA) and was used to determine statistical difference (α = 0.05) among the groups. Tuckey's test was used to calculate P-value (α = 0.05) between two each group.

Results: The highest post-endodontic pain was in Group 3. There was no significance difference between Group 1 and Group 2.

Conclusion: Final flushing of the canal with saline either cold or at room temperature was effective for post-endodontic pain control. This can be promising as an essential step in endodontic treatment to reduce post-endodontic pain. The room-temperature saline as final irrigation showed comparable results to intra-canal cryotherapy.

Mirogabalin as a Therapeutic Option for Neuropathic Pain Emerging Post-Endodontic Treatment: An Observational Study.

J Endod

December 2024

Department of Endodontics, Nihon University School of Dentistry, 1-8-13, Kanda-surugadai, Chiyoda-ku, Tokyo, 101-8310, Japan; Division of Advanced Dental Treatment, Dental Research Center, Nihon University School of Dentistry, Tokyo, Japan.

Introduction: We have recently reported the clinical efficacy of mirogabalin for occlusal pain due to post-traumatic trigeminal neuropathic pain (PTTN-occlusal pain) after endodontic treatment according to the International Classification of Orofacial Pain criteria. This study aimed to determine the mirogabalin administration period and timing of dose reduction and suspension for treating this condition based on managing a certain number of cases.

Methods: Patients diagnosed with PTTN-occlusal pain after or during endodontic treatment were included in the study.

Article Synopsis
  • The study aimed to determine how reducing occlusal surfaces affects postendodontic pain in patients with specific dental issues.
  • Sixty patients with acute pulpitis and apical periodontitis were randomly assigned to either reduce their occlusal surfaces or keep them unchanged, with pain levels measured over time using a visual analog scale.
  • Although pain levels decreased for both groups after treatment, there was no significant difference in pain levels between those who had surface reduction and those who did not.

Article Synopsis
  • The study aimed to evaluate how effective cold saline, curcumin, and regular saline are at reducing pain after endodontic treatment (root canal).
  • A total of 60 participants were divided into three groups to test each irrigant and pain levels were assessed at three different times using a visual analogue scale.
  • Results showed that both cold saline and curcumin significantly reduced post-treatment pain, demonstrating their effectiveness compared to regular saline.

To assess the overall impact of chlorhexidine, when used as an endodontic irrigant/medicament, on post-obturation pain following endodontic treatment by the application of Bayes methods of meta-analysis. This study aimed to combine recently documented evidence using rigorous and specific search criteria. The available data were analyzed using Bayesian methods, which have the advantage of accounting for uncertainties in estimates.
