This comparative analysis aimed to assess two previously reported cohort studies in African\u2010American (Af\u2010A) and Asian\u2010American (As\u2010A) as to the risk for these two populations for clinical attachment loss (CAL) and gingival phenotype.<\/jats:p><\/jats:sec><jats:sec><jats:title>Summary<\/jats:title><jats:p>In comparison of As\u2010A and Af\u2010A cohorts, As\u2010A had higher frequency of thin tissue phenotype, less width of keratinized gingiva (KGW), and more gingival recession (GR). On other hands, Af\u2010A showed higher prevalence of thick phenotype, longer total tooth length and root length (RL). These gingival and dental anatomical patterns suggest there are differential risk for GR, patterns for CAL, and periodontal prognosis between two cohorts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion(s)<\/jats:title><jats:p>Because of nature of dental and gingival anatomy between these two cohorts, As\u2010A are more susceptible in GR and the short RL affords this population less ability to withstand the clinical presentation of periodontal disease. From a therapeutic perspective, clinicians should evaluate patients with different risk assessment based on their dental and gingival characterization. Af\u2010A may have clinical characteristics that makes this population less at risk for mucogingival defects. Conversely, phenotype modification therapy should be considered when treating As\u2010A because of the high prevalence of thin tissue phenotype, inadequate KGW, and GR. Clinicians should also diligently monitor periodontal CAL around the teeth with shorter RL in periodontal or orthodontic therapy for better teeth
