Introduction: Gerontology defined by the Royal Spanish Academy as the science that deals with old age and the phenomena that characterize it. Likewise, knowledge of the sciences of aging has relevant importance in clinical application, specifically at the first level of health care Objective: Identify and reflect on the applications of gerontology as a science in the clinical setting Methodology: A systematic review of scientific literature on gerontology carried out, using scientific search engines: Latindex, Scielo, PubMed and Semantic Scholar. In this sense, two categories focused on for the systematic analysis of the information: 1) Gerontological conceptual approaches, and 2) Professional competencies in the clinical field. Results: Nine articles published between 2016 and 2023 reviewed. In this sense, the identified findings are conceptual approaches and intervention methods in the clinical setting Conclusions: Gerontology is a science with little scientific literature and sufficient research regarding clinical intervention in professional settings. Consequently, recommended to design and execute actions from Higher Education Institutions and public policy to highlight the importance of gerontology in society.
