Periodontal status was recorded using a half\u2010mouth protocol. We estimated the prevalence of periodontitis, evaluated changes in the assignment of stages to combinations of available complexity factors, associated periodontal status with 7\u2010year tooth loss and illustrated agreement with the Centers for Disease Control and Prevention\/American Academy of Periodontology (CDC\/AAP) classification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The total prevalence of periodontitis was 78.6%; 18.0% and 17.4% were Stage III and Stage IV, respectively. Grade C was exhibited by 49.1% of Stage III cases and 37.8% of Stage IV cases. Assignment of stage changed only marginally when complexity factors were considered in addition to interdental clinical attachment levels. Three percent of Stage IV cases and 15.2% of non\u2010classified cases became toothless. Adjusted incidence rates for tooth loss were 3.60 for Stage III cases, 6.55 for non\u2010classified cases and 8.69 for Stage IV cases. Severe cases (CDC\/AAP) corresponded primarily to Stage III (42.9%) and Stage IV (53.0%) cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>For public health purposes, caution should be exercised when translating the periodontitis prevalence according to the ACES framework into treatment requirements.
