Several micro-RNA plays a key role in endothelial function and may be a link for the known interaction of periodontitis and cardiovascular disease. The investigators compared the impact of gingival health, periodontitis (CP), cardiovascular disease or of both diseases (CP +cardiovascular disease) on gingival crevicular fluid miRNA 7a-5p, miRNA 21-3p, miRNA 21-5p, miRNA 200b-3p, miRNA 200b-5p, miRNA 100-5p, miRNA 125-5p levels.
