Background:

the treatments for periodontitis try to achieve the periodontal regeneration of patients, and the use of stem cells and blood components emerges as health technology, so it is necessary to train the periodontist in order to improve their professional performance.

Objective:

to identify the level of knowledge and improvement needs that periodontists have in regenerative medicine with stem cells and blood components, in Santiago de Cuba.

Methods:

a cross-sectional descriptive study was carried out at the Dentistry Faculty of Santiago de Cuba, from September 2019 to March 2020. Theoretical and empirical methods were applied: a questionnaire whose results were classified as sufficient, moderately sufficient and insufficient; and statistics for the analysis of the results.

Results:

no specialist reported sufficient knowledge in the aspects covered, and when calculating the arithmetic mean, below 15% had moderately sufficient knowledge of the aspects that were investigated. The main difficulties were detected in relation to laboratory studies, remission, identification of adverse reactions associated with this therapy, the selection and methods of obtaining blood components, and the clinical-surgical application of the treatment variants available in the province.

Conclusions:

insufficiencies in the knowledge for the application of regenerative medicine with blood components of the specialists in Periodontics surveyed were evidenced, for which an improvement strategy is required to raise the quality of the service.
