A systematic search of Medline (Ovid), Embase, Cochrane Trials, Cochrane Review, CINAHL and PubMed was conducted, guided by a registered protocol.

Two studies reported predictive relationships between oral pathogens and pneumonia, with increased odds of respiratory illness associated with positive PCR results for specific pathogens (OR 9.0, 95% confidence interval [CI] 2.3\u201338.8). Two studies identified poor oral health as a predictor of pneumonia, using validated tools such as the ROAG (OR 1.6, 95% CI 1.1\u20132.5). Mediating factors included enteral feeding, level of IDD, and history of oral disease.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Research consistently finds carriage of potential respiratory pathogens in the oral microbiome of people with IDD.
