Frequency of Pain in Teeth with Irreversible Pulpitis after a Single Visit of Root Canal Treatment Using Cryotherapy

Abstract

Objective: To determine the frequency of pain in teeth with irreversible pulpitis after a single visit of root canal treatment using intra-canal cryotherapy. Study Design: Quasi-experimental study. Place and Duration of Study: Department of Operative Dentistry, Armed Force Institute of Dentistry, Rawalpindi Pakistan from Jun to Dec 2017. Methodology: A total of 140 patients of either gender, aged 20 to 65 years were equally divided into two groups Group-A, in which cryotherapy was used, and Group-B was the Control Group. After anaesthetizing the tooth and application of Rubber Dam, Root canal preparation was done with Protaper next series and copious irrigation of 5.25% Sodium Hypochlorite and 17% Ethylene Diamine Tetra Acetic Acid solution. In Group-A, the final irrigation was done with Normal saline at a temperature of 2.5°C. The Control-Group performed final irrigation with normal saline at room temperature. Obturation was done with cold lateral condensation, and permanent restoration was done with composite. Patients were contacted by telephone after 24 Hours and were asked about pain. Results: The mean age was 39.26±12.61 years. There were 82(58.6%) male and 58(41.4%) female patients. After 24 hours, 56(80%) of the patients in Group-A had no pain, while in the Control-Group, 43(61.4%) were pain-free, with a p-value of 0.016. Conclusion: There was a significant decrease in pain after using cryotherapy in single-visit root canal treatment.
