Figure 1.

Photograph of alveolar bone loss evaluated morphometrically by measuring the linear distance between the cementoenamel junction and alveolar bone crest at two buccal sites on the maxillary second molar (A). The area method was defined by delimitation of the area of bone loss using the alveolar bone crest, the cementoenamel junction and the proximal region of roots of the maxillary second molar on the buccal side as references (B).
