The relationship between alveolar bone height and age in the primary dentition. A retrospective longitudinal radiographic study
The aim of the present study was to describe longitudinal changes in the distance between the alveolar bone crest and the cementoenamel junction (ABC-CEJ), determined radiographically. Bitewing radiographs were obtained from 33 children. The ABC-CEJ distance of 1,500 sites was measured. The analysis was used to assess the effect of age, sex, tooth, side of mouth, jaw, site, and patient on the ABC-CEJ measurements. The overall ABC-CEJ distance seemed to increase with age; however, this was not a linear relationship but followed the pattern of facial growth, with two spots separated by a period of minimal increase.
