Gingivitis is the mildest form of periodontal disease and affects 50% to 90% of adults worldwide.[5] It is ubiquitous and affects males and females, young and old.[1] As defined by gingival bleeding adjacent to ≥1 teeth, about half of the US population has gingivitis with the prevalence slightly greater in males than females, and in black people and Mexican Americans than in white people.[6] There is evidence that the prevalence of gingivitis has been decreasing in developed countries over the last few decades.[7][8][9] Globally, there appears to be considerable heterogeneity in the prevalence of gingivitis with higher prevalence reported in certain parts of the world.[5][10][11][12][13][9][14]
