Evaluation of Post Operative Pain After Using Intracranial Cryotherapy During Single Visit RCT

May 19, 2026 updated by: Islamabad Medical and Dental College

Evaluation of Post Operative Pain After Using Intracranial Cryotherapy During Single Visit Root Canal Treatment in Teeth With Symptomatic Apical Periodontitis

A total of 60 patients presenting with single-rooted teeth exhibiting symptomatic apical periodontitis were subjected to a randomized allocation into two groups of 30 each. Irrigation was done using 3% sodium hypochlorite for 5 seconds in all 60 teeth. Group 1 underwent final irrigation utilizing normal saline at room temperature. Group 2 received final irrigation using normal saline refrigerated between 2-5°C. Pain levels were assessed and recorded before the procedure and at 24 and 48-hour time intervals.

Detailed Description

Objective:

To compare the reduction in post operative pain of treatment group with control group using normal; saline at room temperature at 24 and 48 hours

Methodology:

A total of 60 patients presenting with single-rooted teeth exhibiting symptomatic apical periodontitis were subjected to a randomized allocation into two groups of 30 each. Irrigation was done using 3% sodium hypochlorite for 5 seconds in all 60 teeth. Group 1 underwent final irrigation utilizing normal saline at room temperature. Group 2 received final irrigation using normal saline refrigerated between 2-5°C. Pain levels were assessed and recorded before the procedure and at 24 and 48-hour time intervals.

Statistical analysis:

Statistical packages for the Social Sciences (SPSS) Version 22 will be used for data analysis. Mean and SD and Frequencies will be used for quantitative variables (Age and pain), and frequency and percentage for qualitative variable (gender). The continuous variable pain score will be compared among control and cryotherapy group by using independent sample t test. Effect modifiers ( age and gender) will be stratified by using post stratified independent sample t test .The P value < 0.05 will be considered as the threshold for statistical significance, at a confidence interval of 95%.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention Group
In the cryotherapy group, following completion of biomechanical preparation, the root canals will be irrigated with 20ml of 0.9% physiological saline solution at a temperature of 1.5-2.5°C for 5 min
In this study participant are suing 0.9% normal saline but the temperature will be different for both groups .In cryotherapy group participant are using saline at cold temperature1.5-2.5°C
No Intervention: Control Group
In the control group, final irrigation will be performed using 20 mL of 0.9% physiological saline solution at room temperature for 5 min

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To evaluate the reduction of postoperative pain
Time Frame: 24-48 hours
Patients will be instructed to record their pain score on VAS at 24 and 48 h. and will be asked to contact and visit in case they experience severe pain. If visit is not possible,a telephonic feedback will be recorded and assistance will be guided
