Introduction:

chronic kidney disease is defined by the presence of kidney damage and has a negative impact on the health and quality of life of patients. Periodontitis is the chronic inflammation of the supporting tissues of the tooth.

Objective:

to describe the association that has been established between these two diseases.

Methods:

a documentary type study was carried out, with an updated review of scientific articles from databases such as Pubmed, Scielo and Google Scholar in the period from October 2021 to February 2022. Twenty-five scientific texts written in Spanish and English published between 2017 and 2021 were selected.

Results:

most of the literature consulted describes that there is a direct relationship between both diseases, the constant presence of uremia, as well as poor oral hygiene in these patients, is related to immune dysfunction that decreases the host response to bacteria.

Conclusions:

in periodontal disease there is a permanent inflammatory state that aggravates the prognosis of chronic renal failure, so it is necessary to maintain an adequate oral health to avoid systemic complications in vulnerable patients such as those with chronic renal disease.
