Study summary

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.

Read the 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%.

Study arms

  • 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

    Drug: Saline 0.9% (1.5-2.5°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

Interventions

  • DrugSaline 0.9% (1.5-2.5°C)

    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

What researchers measure

Primary outcomes

  1. To evaluate the reduction of postoperative pain

    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

    Time frame: 24-48 hours

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jul 2026; primary completion for Jan 2027, 6 months later.

Of 27 non-industry interventional studies with no phase under Periapical Diseases, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 32. This study's planned 6 months is below that.

Counting every sponsor, half of 27 studies reached it within 24 months; a quarter within 12 and three quarters within 32.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 20, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
