Long term dental neglect has resulted in a progressive inflammatory response
that, in some areas, has initiated a fibrous tissue development. Note areas of
inflammation and fibrous gingiva. Malpositioned teeth contribute to
inadequate cleansing and dental plaque accumulation).

a. General. Periodontitis (figure 1-6) is an inflammation of the tissues
supporting the teeth. It is also commonly known as "pyorrhea." If untreated, the tooth
may be lost through destruction of the supporting tissues.
NOTE: Deposit of minerals from the saliva into dental plaque results in a hard calculus
formation. The pockets between the teeth and gingival tissue deepen as
periodontal disease progresses. Calculus formation in periodontal pockets
makes plaque removal more difficult, contributing to progress of the disease
and destruction of the bony support of the teeth.
