Intraoral Cryotherapy in Root Canal Retreatment

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.
