Abstract

Objectives

Alveolar bone loss (ABL) and periodontal lesions are common diseases that have an undeniable effect on teeth maintenance and health. Current diagnostic methods include probing, intraoral radiography, and panoramic radiography; each has its limitations. In this study, we aimed to assess the diagnostic accuracy of panoramic radiography in the diagnosis of interdental ABL.

Material and Methods

In this cross-sectional study, panoramic and cone-beam computed tomography (CBCT) images from 80 patients were collected from the archives of an oral and maxillofacial radiology center. The amount of ABL was obtained by measuring the distance from the Cemento-Enamel Junction (CEJ) to the alveolar bone crest on both panoramic and CBCT images. Patients were divided into healthy (ABL ≤ 2 mm) and diseased (2 mm < ABL) groups in terms of periodontal disease.

Results

There was no statistically significant difference in the average ABL in the premolar, maxillary molar, and mandibular molar areas between the two techniques. However, in other areas, the ABL size was significantly lower in the panoramic view (p < 0.05). Also, the panoramic technique correctly recognized 89.1% of normal and 88.4% of ABL cases. The overall accuracy of panoramic radiography in the diagnosis of ABL was 85%, indicating the good accuracy of this technique. In maxilla, the highest diagnostic accuracy of the panoramic technique was in the molars, and the lowest was in the incisors. In the mandible, the highest and lowest diagnostic accuracy of the panoramic technique was related to molars and premolars, respectively. According to the kappa statistic, there was a significant good to very good agreement between the two types of techniques in all maxillary areas (p < 0.001).

Conclusions

Panoramic radiography is accurate in showing ABL. Measuring ABL in the posterior mandibular areas in panoramic radiographs is quite reliable; however, in general, digital panoramic radiography shows less ABL than the actual amount.

使用 CBCT 评估牙槽骨间缺损的全景放射诊断准确性

目的牙槽骨缺失（ABL）和牙周病是常见疾病，对牙齿的维护和健康有着不可否认的影响。目前的诊断方法包括探诊、口内放射摄影和全景放射摄影，但每种方法都有其局限性。在本研究中，我们旨在评估全景放射摄影在牙间 ABL 诊断中的准确性。材料和方法在这项横断面研究中，我们从口腔颌面放射中心的档案中收集了 80 名患者的全景和锥形束计算机断层扫描 (CBCT) 图像。通过测量全景和 CBCT 图像上 Cemento-Enamel Junction（CEJ）到牙槽骨嵴的距离，得出 ABL 的数量。根据牙周疾病将患者分为健康组（ABL ≤ 2 mm）和疾病组（2 mm < ABL）。结果两种技术在前磨牙、上颌臼齿和下颌臼齿区域的平均 ABL 没有明显的统计学差异。然而，在其他区域，全景视图的 ABL 尺寸明显较低（p < 0.05）。此外，全景技术能正确识别 89.1% 的正常病例和 88.4% 的 ABL 病例。全景放射摄影诊断 ABL 的总体准确率为 85%，表明该技术具有良好的准确性。在上颌，全景技术诊断准确率最高的是臼齿，最低的是门齿。在下颌，诊断准确率最高和最低的分别是磨牙和前磨牙。根据卡帕统计，在所有上颌区域，两种技术之间的一致性都非常好（p <0.001）。结论全景放射摄影可准确显示 ABL。在全景X光片中测量下颌后牙区的ABL是相当可靠的；但是，一般来说，数字全景X光片显示的ABL比实际数量要少。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
