Introduction:

Paraprosthetic lesions are alterations of the oral mucosa associated with the use of dental prosthesis, which can cause serious complications.

Objective:

To identify the risk factors related to the paraprosthetic lesions in patients with removable prosthesis.

Method:

An observational and descriptive study of 180 patients with paraprosthetic lesions was carried out; they were assisted in Mártires del Moncada Teaching Provincial Stomatological Clinic in Santiago de Cuba, from February, 2019 to May, 2020. The following variables were selected: age, sex, risk factor and type of paraprosthetic lesion.

Results:

There was a prevalence of the 60 years and over patients, sub prosthesis stomatitis (52.7 %) and risk factors, such as mucosoported prosthesis, longer time using it, as well the habit of sleeping with the prosthesis.

Conclusions:

The most frequent paraprosthetic lesion was the sub prosthesis stomatitis due to the persistence of the same risk factors that impacted in the population through the time.
