ABSTRACT

Objective: The aim of this clinical trial was to assess whether controlled irrigation with three cryotherapy protocols with different temperature would result in a reduced of post-endodontic pain after one-visit and two visits root canal treatment in teeth with necrotic pulps. The null hypothesis was that there would be no difference between the control group and cryotherapy groups in terms of post-endodontic pain. Materials and Methods: Two hundred and forty patients aged 18-65 years were treated with three cryotherapy protocols with different temperature after one-visit and two visits root canal treatment detected with only necrotic pulps. All canals were clean and shaped with Reciproc instruments. Final irrigation with cold (6oC, 2.5oC, and room temperature) 17% EDTA and 10 mL cold saline solution. Results: No statistically relevant modification (p > .05) between the control group and group A were encountered concerning level or period of pain. There was no statistically relevant difference (p> .05) among Group A and CG compared with Group B. Group B showed less pain than the rest of the groups. Cryotherapy protocols used in the two experimental groups can help dentists to manage pain in root canal treatments with vital pulps. Conclusion: The methodology in both selecting the participants in the study and analyzing the data in this randomized clinical trial permitted us to conclude that cryotherapy aids clinical procedures to clean and shape the canals in order to reduce the occurrence of post-endodontic pain and the need for a prescription in patients with a diagnosis of vital pulp.
