Observational studies investigating the association between OSA and periodontitis in human adults were included. Study quality was assessed using the ROBINS\u2010I tool.

Although causality cannot be established due to the observational nature of the included studies, shared inflammatory and microbiological pathways support a biologically plausible link.
