Introduction:

At present, new non-invasive alternatives are used for the removal of various inflammatory processes of the oral mucous epithelium; being cryotherapy a physiotherapeutic technique based on the application of intense cold with liquid nitrogen to produce freezing on the skin or mucous membranes of the organism and local destruction of affected cells and tissues in controlled manner.

Objective:

To evaluate the therapeutic effects of cryotherapy in geriatric patients with sub-prosthesis stomatitis.

Methods:

A descriptive and cross-sectional study of 50 older adult patients, of both sexes, clinically diagnosed with subprosthesis stomatitis and assisted in the dentistry consultation of the Specialties Polyclinic referring to the Saturnino Lora Torres University Clinical Surgical Hospital in the city of Santiago de Cuba, in the period from March 2022 to the same month of 2023.

Results:

It was evidenced that freezing between 20 and 30 seconds and thawing between 91 and 120 seconds were the most effective in the destruction of the damaged palatal mucosa, achieving tissue regeneration in a minimum time with the performance of 1 to 3 cycles of rapid cooling and slow thawing in a therapeutic session. The absence of symptoms was the most relevant in the post-surgical evolution.

Conclusions:

Cryotherapy proved to be an effective and innocuous method to regenerate injured tissues when fast freezing with slow thawing. This cryosurgical method, easy to apply and atraumatic, achieved optimal repair and re-epithelization of damaged oral tissues with excellent therapeutic responses, avoiding post-surgical complications such as infection and local bleeding.
