Age‐dependent distribution of periodontitis in two countries: Findings from NHANES 2009 to 2014 and SHIP‐TREND 2008 to 2012

Abstract

Despite substantial differences in the overall severity of attachment loss between the two samples, common patterns of CAL and of the relative contribution of R and PD to CAL with increasing age were identified. Although periodontitis severity may vary in different populations, empirical evidence-driven definitions of CAL thresholds signifying disproportionate severity of periodontitis by age are feasible.
