The purpose of the present study was to investigate associations between radiographic crestal lamina dura and the clinical periodontal status of the corresponding interdental area. The population consisted of 90 individuals (53 females and 37 males), ages 21 to 45 years (mean 31 years), who underwent a comprehensive periodontal examination. Buccal and lingual to the contact point at each interdental area four different clinical criteria were scored as being present or absent: (i) visual inflammation, (ii) bleeding after probing with 25 gm force, (iii) pocket depth greater than 3 mm after probing with 50 gm force, (iv) loss of connective tissue attachment. Bite-wing and full-mouth periapical radiographs were taken and processed using standardized techniques. Each interdental crestal area on the radiographs was examined and scored for presence or absence of an intact lamina dura. Statistical analyses were undertaken using correlated means to compare the presence or absence of lamina dura with the individual and simultaneous clinical criteria. No significant differences were obtained between any of the comparisons and, in addition, there was no correlation between lamina dura images on periapical and bite-wing radiographs. The results indicated that crestal lamina dura on radiographs did not appear to be related to the presence or absence of clinical inflammation, bleeding upon probing, periodontal pockets or loss of attachment.
本研究的目的是调查X线片上的牙槽嵴硬骨板与相应牙间区域临床牙周状况之间的关联。研究对象包括90名年龄在21至45岁（平均31岁）的个体（53名女性和37名男性），他们接受了全面的牙周检查。在每个牙间区域接触点的颊侧和舌侧，对以下四种不同的临床标准记录其有无：（i）可视炎症，（ii）用25克力探诊后出血，（iii）用50克力探诊后袋深大于3毫米，（iv）结缔组织附着丧失。采用标准化技术拍摄并处理咬合翼片和全口根尖片。检查X线片上每个牙间牙槽嵴区域，记录有无完整的硬骨板并评分。采用相关均值进行统计分析，以比较硬骨板的有无与个体及同时存在的临床标准之间的关系。任何比较之间均未获得显著差异，此外，根尖片和咬合翼片上的硬骨板影像之间也无相关性。结果表明，X线片上的牙槽嵴硬骨板似乎与临床炎症、探诊出血、牙周袋或附着丧失的有无无关。
