Epidemiological studies on the prevalence of marginal alveolar bone loss (ABL) in children and adolescent are often based on a single range of measurements from the cemento-enamel junction to the alveolar bone crest (CEJ-ABC distance). For individual diagnosis however, the clinician must take in consideration that the CEJ-ABC distances in the primary dentition increase with age, and significantly differ among sites. The purpose of the present study is to present the range and cumulative probabilities of the CEJ-ABC distances, at the primary cuspid-molar area, to be utilized for the individual diagnosis of ABL on bite wing radiographs of the primary dentition. In bite-wing radiographs from 316 children aged 4 to 12 years, the normal CEJ-ABC distances were measured in 0.1 mm increments at 2007 sites; mesial surfaces of the primary molars, and distal surfaces of the primary molars and cuspids. A positive correlation was found between the mean CEJ-ABC distance per patient and age. Most of the measurements were < 2 mm, and measurements between 2 to 3 mm were found, in low percentages after age 9, at the distal surfaces of teeth 53, 63, 54, 64, 73 and 83 and the mesial surfaces of teeth 54, 64.
关于儿童和青少年边缘性牙槽骨吸收（ABL）患病率的流行病学研究通常基于从牙骨质-釉质界到牙槽嵴顶（CEJ-ABC距离）的单一测量范围。然而，对于个体诊断，临床医生必须考虑到乳牙列中CEJ-ABC距离会随着年龄增长而增加，并且不同部位之间存在显著差异。本研究的目的是呈现乳牙尖牙-磨牙区CEJ-ABC距离的范围和累积概率，以便用于乳牙列咬合翼片上ABL的个体诊断。在316名4至12岁儿童的咬合翼片中，在2007个部位以0.1毫米的增量测量正常的CEJ-ABC距离；这些部位包括乳牙磨牙的近中面、乳牙磨牙和尖牙的远中面。发现每位患者的平均CEJ-ABC距离与年龄之间存在正相关。大多数测量值<2毫米，9岁以后，在牙齿53、63、54、64、73和83的远中面以及牙齿54、64的近中面，2至3毫米的测量值占比很低。
