[Research progress in the relationship between periodontitis and anxiety disorders/depression disorders].

Abstract

Periodontitis, a common chronic inflammatory disease, progressively damages the supporting tissues of teeth, ultimately resulting in tooth loss. The rising incidence of periodontitis in adults has prompted researchers to observe a frequent co-occurrence of mental health disorders (such as anxiety disorders, depression disorders) in patients undergoing periodontitis onset and treatment. The existence of severe periodontitis can even aggravate the mental and psychological disorders of patients. Furthermore, the long-term fast-paced, high-pressure modern life is easy to cause a series of psychological problems, in turn affecting the occurrence and development of periodontitis. At present, researchers have reported the correlation between periodontitis and anxiety disorders/depression disorders. However, due to the lack of systematic understanding, most of them are clinical investigations or epidemiological statistics without deep mechanism studies. In view of the above problems, this article elucidates the bidirectional relationship between periodontitis and depression/anxiety disorders in recent years by examining recent epidemiological findings, exploring potential bidirectional pathogenic mechanisms, and discussing current treatment strategies. Ultimately, this review seeks to provide new perspectives for improving both oral and mental health outcomes in patients affected by periodontitis and anxiety/depression disorders.
