Localized aggressive periodontitis

Periodontal disease describes a mixture of diseases in which the periodontal attachment is destroyed, resulting in loose teeth that may exfoliate. Periodontitis is divided into chronic and aggressive forms that are localized or generahzed (affect few or many teeth). Chronic periodontitis is very common (Sects. 13.1.2-13.4.3), whereas aggressive periodontitis is rare (Chap. 14). The collagen fibers of the gingiva and periodontium are described in Chap. 3 (Sect. 3.1.5), and its epithelial cover in Chap. 5 (Sect. 5.2.3).
