The natural history of changes in attachment level in the primary dentition should be determined before considering diagnostic criteria for periodontal diseases in children. The present study was designed to describe longitudinal changes in the distance between the alveolar bone crest and the cementoenamel junction (ABC-CEJ) determined radiographically. Bite-wing radiographs were obtained from 33 children as part of a routine annual dental examination in a rural community. The ABC-CEJ distance of 1500 sites located at the mesial and distal aspects of primary molars and distal aspect of primary cuspids were measured. An analysis of variance model was used to assess the effect of age, sex, tooth, side of the mouth, jaw, site and patient on the ABC-CEJ measurements. The side of the mouth (left, right) and the site (mesial, distal) had no significant effect on the ABC-CEJ distance. ABC-CEJ distances in the upper jaw were greater than in the lower jaw, and different teeth exhibited different ABC-CEJ distances. Canines had the greatest distance and second molars the smallest. The most interesting relationship was between alveolar bone height and age. 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 spurts separated by a period of minimal increase. The results indicate that different levels of ABC-CEJ distance might be considered as a cut-off value for radiographic diagnosis of alveolar bone loss at different ages, for different primary teeth and for different jaws.
在考虑儿童牙周疾病的诊断标准之前，应先确定乳牙列附着水平变化的自然史。本研究旨在描述通过影像学确定的牙槽嵴顶与牙骨质釉质界（ABC-CEJ）之间距离的纵向变化。作为农村社区常规年度牙科检查的一部分，从33名儿童中获取了咬合翼片。测量了位于乳磨牙近中面和远中面以及乳尖牙远中面的1500个部位的ABC-CEJ距离。采用方差分析模型评估年龄、性别、牙齿、口腔侧、颌骨、部位和患者对ABC-CEJ测量值的影响。口腔侧（左、右）和部位（近中、远中）对ABC-CEJ距离无显著影响。上颌的ABC-CEJ距离大于下颌，不同牙齿表现出不同的ABC-CEJ距离。尖牙的距离最大，第二乳磨牙的距离最小。最有趣的关系是牙槽骨高度与年龄之间的关系。总体ABC-CEJ距离似乎随年龄增加；然而，这不是线性关系，而是遵循面部生长模式，有两个快速增长期，中间间隔一段增长最小的时期。结果表明，不同水平的ABC-CEJ距离可作为不同年龄、不同乳牙和不同颌骨牙槽骨丧失影像学诊断的临界值。
