The purpose of the present study was to assess periodontal destruction and related etiological factors in three young adult male populations in the U. S. A., Norway, and Sri Lanka. The clinical examination included the Plaque Index (Silness & Löe 1964), Retention Index for calculus, defective fillings, and gingival caries (Löe 1967), Gingival Index (Löe & Silness 1963), and Loss of Attachment (Ramfjord 1959). Plaque accumulation, calculus deposition, and gingival inflammation were higher in interproximal than buccal areas. Plaque and Gingival Index scores remained constant over the entire age range in each population. The filling experience was high in Norway compared to the U. S. A. and Sri Lankan populations where few defective fillings were found. Caries related to the gingival margin were rare in all three populations. Loss of attachment increased with age and was greater on buccal surfaces than mesial surfaces. The distribution of attachment loss was similar in the three populations, and the greatest attachment loss involved maxillary first molars, maxillary and mandibular first premolars, and mandibular incisors. Rates of attachment loss in these young populations were low, averaging less than 0.06 mm per year.
