Subjects with chronic periodontitis typically had 4\u20135\u00a0mm attachment loss affecting a few molars or premolars. Subjects with aggressive periodontitis had \u22655\u00a0mm attachment loss affecting multiple teeth, and 68% and 73% of these subjects had \u22656\u00a0mm attachment loss affecting maxillary and mandibular molars respectively. Attachment loss and periodontitis were significantly more prevalent in the 19\u201325\u00a0years group, than the 12\u201318\u00a0years age group.
