A 15-MHz B-mode ultrasonographic image of periodontal structures of a maxillary incisor and anatomic schema. a A sagittal ultrasonographic image through a maxillary incisor. GT3 was measured at the 3 mm level apical to gingival margin while ACT was measured at the alveolar crest. b Schematic of morphometrical analysis of periodontal tissues in a US image. Tissues are indicated as follows; 1, enamel; 2, gingival margin; 3, cementoenamel junction; 4, gingiva; 5, cementum and 6, the crest of alveolar bone
