Bone Loss and Patterns of Bone Destruction • Although periodontitis is an infectious disease of the gingival tissue, changes that occur in bone are crucial because the destruction of bone is responsible for tooth loss.
Bone loss that occurs with cancer therapy is generally more rapid and severe than postmenopausal bone loss in women or normal age-related osteoporosis in men. Rates of bone loss occurring with cancer therapy can be up to tenfold higher than normal (Fig. 1 ⇓ ) [ 4 , 9 – 14 ].

Unless treated by scaling and surgical removal of the periodontal pocket, periodontitis gradually leads to tooth loss by progressively destroying the alveolar crest (Fig. 3-31) . The pattern of bone destruction depends on the location of the periodontal pocket.
In periodontal disease, not only does the bone that supports the teeth, known as alveolar bone, reduce in height in relation to the teeth, but the morphology of the remaining alveolar bone is altered. The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms.
