Clinical Trial Summary

The aim of this study was to evaluate the effect of intraoral cryotherapy application on postoperative pain in single and multiple visit retreatment of teeth with symptomatic or asymptomatic apical periodontitis. This clinical trial was also investigate the potential of intraoral cryotherapy application to reduce on postoperative analgesic use of patients in line with the results obtained.

A total of 118 patients who met the inclusion criteria were selected for the study. The patients were randomly divided into two groups as single visit and multiple visit (n=59). Then, each group was randomly divided into three subgroups as control (without cryotherapy), 15 minutes of cryotherapy, and 30 minutes of cryotherapy. Twenty two teeth were retreated in each cryotherapy group and 15 teeth in each control group. Visual analogue scale (VAS) was used to evaluate and compare postoperative pain. Postoperative analgesic use of patients was also recorded.

• Periodontitis

Intervention

Procedure:
• intraoral ice pack application
Tap water was filled into plastic ice molds and kept in the freezer in the clinic until the application was made. The ice packs used were weighed with digital pocket scale (Knmaster CT1000, Turkey) as 6-8 grams. In the cryotherapy groups, at the end of the first appointment ice packs were removed from the freezer, wrapped in sterile gauze and placed on the vestibular mucosa of the teeth.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Levels of postoperative pain	The primary endpoint in calculating the sample size was to obtain visual analog scale (VAS) values. The intensity of postoperative pain was evaluated with visual analogue scale, which is a 10 cm line representing a continuum of pain levels between "no pain" on the left side and "most severe pain" on the right side between 0 and 10.	6 hours
