Using automated Application Programming Interface queries, we retrieved publications jointly referencing 256 systemic conditions (defined using the Agency for Healthcare Research and Quality\u2019s Clinical Classifications Software) and 5 oral health conditions (periodontal disease, dental caries, tooth loss, oral ulcers, and oral cancers). Search strategies combined Medical Subject Headings and title\/abstract terms. Co-occurrence data were normalized using max scaling and analyzed using hierarchical clustering, K-means clustering, and network visualizations. This study reports associations between conditions and not causal relationships.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The search identified 79\u2009817 co-mention instances across 39\u2009782 unique publications. Of 256 medical conditions, 237 co-occurred with at least one oral condition. Periodontal diseases and oral cancers accounted for the largest share of co-mentions (42\u2009554 and 38\u2009735, respectively). Hierarchical clustering of systemic conditions revealed eight clusters, including malignancies strongly co-occurring with oral cancers and immunity disorders co-occurring with periodontal diseases. Dental conditions grouped into three clusters: (1) caries, ulcers, and tooth loss; (2) oral cancers; and (3) periodontal diseases. Publication-level clustering identified 6 thematic domains dominated by oncology and inflammation research.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
