The clinical signs of chronic periodontitis as inflammation, pocket formation, attachment loss, and alveolar bone loss are believed to be caused by the direct effects of sub-gingival plaque accumulation. This explains why pocket formation, attachment loss and bone loss may occur on one surface of a tooth while other surfaces maintain normal attachment levels.(46) In addition, chronic periodontitis may be described as being localized, when few sites of the periodontium affected by attachment and bone loss (30% of the sites assessed in the mouth demonstrate attachment loss and bone loss), or generalized, when many sites of the periodontium are affected (when 30% or more of the sites assessed in the mouth demonstrate attachment loss and bone loss)
