Research progress on the potential correlation between polycystic ovary syndrome and periodontal disease

Over the past few years, the correlation between periodontal disease (PD) and polycystic ovary syndrome (PCOS) has attracted widespread attention owing to the increased incidence of these diseases. Several studies have suggested a possible link between the two. In this narrative review, we examined the epidemiology, common risk factors, and pathological mechanisms of PCOS and PD to investigate the potential association between these diseases. Evidence from the literature indicates that PCOS and PD can interact with each other. Common risk factors, such as microbial homeostasis imbalance owing to dysbiosis, along with multiple hormone and inflammatory mediators, as well as inflammatory responses owing to oxidative stress and oxidative responses owing to ferroptosis, are all associated with the pathogenesis of both diseases. Further studies are needed to clarify the specific mechanisms of interaction between PCOS and PD, which could clarify future directions in disease management and combined multidisciplinary treatment.
