Introduction:

Endodontics is the dental discipline that deals with the morphology, physiology and pathology of the dental pulp and periradicular tissue. It includes the etiology, prevention, diagnosis and treatment of pulp disorders, as well as its repercussions in the periapical region and the rest of the organism. The purpose is to relieve pain and preserve the teeth in function. Pain originating from teeth or surrounding tissues is one of the main reasons for dental consultation.

General objective:

explain the implementation of cryotherapy in endodontics.

Specific objectives:

to analyze its physiological mechanism of action; the efficacy in reducing pain in endodontic therapies with different initial diagnoses; describe its forms of clinical application; establish the contraindications or possible inconveniences that its application may present.

Methodology:

The work is a narrative review. The bibliographic search was carried out with the following MeSH (Medical Subject Heading) terms: cryotherapy, endodontic, intracanal irrigation, dental pain and their corresponding descriptors in DeCS health sciences: cryotherapy, endodontics, intracanal irrigation and dental pain. The inclusion criteria were: articles available in full text that contain at least one keyword in the title and/or abstract, in English, Spanish or Portuguese, with no time limit. Articles with studies in animals or in deciduous teeth were excluded.

Conclusions:

According to the present work, there are scientific studies that positively support the application of cryotherapy for pain control in endodontics.
