EVALUATION OF POSTOPERATIVE PAIN AFTER VARIOUS CRYOTHERAPY APPLICATIONS IN TEETH WITH CHRONIC IRREVERSIBLE PULPITIS – AN IN VIVO STUDY.

Abstract

Aim: To evaluate the effect of various Cryotherapy applications on post operative pain in teeth with Chronic Irreversible Pulpitis.
Methodology: A total of 40 patients with Chronic Irreversible Pulpitis were randomly divided into four groups depending upon the type of Cryotherapy; Control group – No Cryotherapy application; Intracanal Cryotherapy application with 20ml saline as final irrigant at 4 degree C; Intraoral Cryotherapy application with ice packs placed on vestibular region of treated tooth; Extra oral Cryotherapy application with icepacks placed extraorally on cheek surface. The postoperative pain of the patients was recorded at the first, third, fifth, and seventh days.
Results: The data were statistically analyzed by using Mann-Whitney U test and Student’s t test (P = .05). when compared with control group, all Cryotherapy groups exhibited less percussion pain and less postoperative pain.
Conclusion: within the limitations of the study, all the Cryotherapy applications resulted in lowering of post operative pain.
Clinical significance: Application of Cryotherapy results in decreased blood flow, inhibition of neural receptors in tissues results in reduction of postoperative pain.
