Periodontal disease affects the gums and the tissues surrounding the teeth and has a multifactorial etiology. In some cases, periodontal disease, depending on its form, whether mild or more moderate, can cause tooth loss. In this context, depression and anxiety have been gaining notoriety as risk indicators for the manifestation and progression of periodontal disease. In this way, the present work aims to carry out a literature review to identify the association between anxiety and depression (psychological states) in periodontal disease. The methodology used was the literature review. Data collection was carried out in the period of August and September 2022, and covered publications from the years 2015 to 2022. Twenty-five publications were selected to compose the present work, and the year 2020 was the one that presented the most publications on the theme depression and anxiety in periodontal disease, with n=7, followed by the year 2019, with n=5. In the end, it was concluded that depression and anxiety are factors that may favor the emergence of periodontal diseases, since these psychological changes make the individual's immune response more susceptible to immunoinflammatory changes.
