This study examined the significance of age and clinical factors on the diagnosis of alveolar bone loss (ABL) as evidenced by increased cementoenamel junction (CEJ)--alveolar bone crest (ABC) distances. The CEJ-ABC for the first and second primary molars were 0.97 +/- 0.3 mm and 0.78 +/- 0.3 mm, respectively. Age correlated significantly with the means CEJ-ABC per patient and second primary molars. Correlations between probing depths and CEJ-ABC were not significant. Analysis of variance indicated significant differences between CEJ-ABC grouped by presence/absence of proximal contact, presence/absence of lamina dura and proximal contact, presence/absence of lamina dura and proximal caries severity (PCS). Differences in the CEJ-ABC grouped by gender and gingival index (GI) were not significant. When considering the effect of age PCS or GI when controlling for the other factors (Multiple regression analysis) age and PCS had a significant effect on the CEJ-ABC. Proximal contact loss or lack of lamina dura may relate to ABL in the primary molars.
本研究通过牙骨质釉质界（CEJ）-牙槽嵴顶（ABC）距离增加来检测年龄和临床因素对牙槽骨吸收（ABL）诊断的意义。第一乳磨牙和第二乳磨牙的CEJ-ABC分别为0.97±0.3毫米和0.78±0.3毫米。年龄与每位患者及第二乳磨牙的平均CEJ-ABC显著相关。探诊深度与CEJ-ABC之间的相关性不显著。方差分析表明，按邻面接触存在与否、硬骨板存在与否及邻面接触、硬骨板存在与否及邻面龋严重程度（PCS）分组的CEJ-ABC之间存在显著差异。按性别和牙龈指数（GI）分组的CEJ-ABC差异不显著。在控制其他因素时考虑年龄、PCS或GI的影响（多元回归分析），年龄和PCS对CEJ-ABC有显著影响。邻面接触丧失或硬骨板缺失可能与乳磨牙的ABL有关。
