Cryotherapy Effectively Reduces Postoperative Pain After Root Canal Treatment, suggests study
Researchers have found in a new study that Cryotherapy may significantly reduce postoperative pain in single-visit root canal treatments of molars with pulp necrosis and symptomatic apical periodontitis (SAP). This offers a biocompatible, cost-effective, and simple pain management option.
The present study aimed to assess the effects of intracanal cryotherapy on pain following single-visit non-surgical root canal treatment (NSRCT) of molar teeth with pulpal necrosis and symptomatic apical periodontitis (SAP).
This parallel-two arm, single-blind, randomized superiority clinical trial was registered at www.clincaltrials.gov (NCT05611736). Patients referred for NSRCT meeting the inclusion criteria were included. Preoperative radiographs, pulp sensibility tests, and pain scores on the visual analog scale (VAS) were recorded. Following shaping and cleaning, 302 patients were randomly allocated to the two groups (n = 151). In the experimental group, final irrigation was done using 0.9% physiologic saline solution at 2.5 °C, whereas in the control group, final irrigation was done using the same solution at room temperature.
