The aims of this cross\u2010sectional study were (a) to provide estimates on the prevalence, severity and extent of mid\u2010buccal GRs according to the 2018 classification and (b) to identify their risk indicators in the adult U.S. population from the NHANES database.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Data from 10,676 subjects, representative of 143.8 millions of adults, were retrieved from the NHANES 2009\u20132014 database. GR prevalence was defined as the presence of at least one mid\u2010buccal GR \u22651\u00a0mm. GRs were categorized following the 2018 World Workshop classification system (RT1, RT2, RT3) and according to different severity cut\u2010offs. An analysis for GR risk indicators was also performed, selecting subjects without periodontitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The patient\u2010level prevalence of mid\u2010buccal GRs (all types) was 91.6%, while it decreased to 70.7% when considering only the aesthetic zone. When focusing on RT1 GRs, the patient\u2010level prevalence (whole mouth) was 12.4%, while it was 5.8% considering only the aesthetic zone. The majority of RT1 GRs were considered as mild (1\u20132\u00a0mm). The whole\u2010mouth patient\u2010level prevalence of RT2 and RT3 GRs was 88.8% and 55.0%, respectively. Age (35\u201349\u00a0years), gender (female), ethnicity (non\u2013Hispanic Whites), last dental visit (&gt;6\u00a0months before), tooth type (incisors) and the arch (mandible) resulted as risk indicators associated with the presence of RT1 GR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Mid\u2010buccal GRs affect almost the entire US population.
