Cryotherapy as a non pharmacological alternative for the management of postoperative endodontic pain after one visit root canal treatment using three irrigating regimens at different temperatures

Abstract

Background: The goal of the present study was to assess the effect of cryotherapy application at various temperatures in the reduction of postoperative pain after a single-visit (SV) root canal treatment (RCT). Aim: The present study aimed to evaluate the postoperative pain after intracanal cryotherapy with saline at different temperatures. Methodology: Sixty participants aged ≥18 years were included in this clinical trial. All patients with good general health indicated for SV RCT were included in the present study. Preoperative Visual Analog Scale (VAS) scores were obtained by percussing the tooth, and written consent was obtained. The access cavities were prepared, cleaning and shaping were done, and the patients were allocated into three groups based on final irrigation: Group I – saline at room temperature (37°C) (control group), Group II – cold saline (at 4°C), and Group III – cold saline (at 2.5°C). After drying, the canal obturation was done in the same appointment. Postoperative pain was recorded at 24, 48, and 72 h and 7 days with VAS. In case of severe pain, an analgesic was prescribed. Statistical Analysis Used: The Chi-square test was used to analyze the data. Results: Both cryotherapy irrigation groups showed the lowest postoperative pain at 24, 48, and 72 h and after 7 days. The analgesic intake was higher in Group I as compared to other groups. Conclusion: Cryotherapy is a promising nonpharmacological treatment alternative for postoperative pain in SV RCT.
