Baseline examination was carried out in 1987 and follow\u2010up examinations in 1994 and 2002. In 2002, 128 subjects could be retrieved from the original group of 255. Baseline examination included evaluation of plaque, bleeding on probing, calculus, pocket depth, attachment loss and presence of <jats:italic>Actinobacillus actinomycetemcomitans<\/jats:italic>, <jats:italic>Porphyromonas gingivalis, Prevotella intermedia<\/jats:italic>, spirochetes and motile microorganisms.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> The mean attachment loss increased from 0.33\u2003mm in 1987 to 0.72\u2003mm in 1994 and 1.97\u2003mm in 2002. Analysis identified the amount of subgingival calculus and subgingival presence of <jats:italic>A. actinomycetemcomitans<\/jats:italic> as risk factors, and age as a risk determinant, for the onset of disease.
