摘要

目标咬翼放射摄影被认为在龋病检测中具有很高的诊断价值,但由于投影的原因,病变可能仍未被发现。新型咬翼+(BW +)技术可在不同方向和角度滚动浏览射线照片。本研究旨在比较 BW + 与其他二维和三维成像方法的灵敏度、特异性和用户可靠性。三具尸体的天然牙齿是在死后移植的。采用 BW +、二维(数字传感器、成像板、二维和三维咬翼X光片)和三维方法(高剂量和低剂量 CBCT)。对 96 颗牙齿三个位置(中侧、远侧和咬合面)的龋坏进行了评估,并由十名观察者根据其脱矿程度进行评分,结果在所有观察者和环境中得出 35,799 个可能的龋坏。结果总体而言,放射学评估显示假阴性诊断率很高,约有 70% 的病变未被发现,尤其是釉质病变。结论在研究范围内,BW + 显示出巨大的诊断价值潜力,尤其是在牙本质龋方面。然而,必须根据每位患者的年龄和风险来权衡诊断效益和辐射暴露。

Eligibility of a novel BW + technology and comparison of sensitivity and specificity of different imaging methods for radiological caries detection

Eligibility of a novel BW + technology and comparison of sensitivity and specificity of different imaging methods for radiological caries detection

Objectives

Bitewing radiography is considered to be of high diagnostic value in caries detection, but owing to projections, lesions may remain undetected. The novel bitewing plus (BW +) technology enables scrolling through radiographs in different directions and angles. The present study aimed at comparing BW + with other 2D and 3D imaging methods in terms of sensitivity, specificity, and user reliability.

Materials and methods

Five human cadavers were used in this study. In three cadavers, natural teeth were transplanted post-mortem. BW + , two-dimensional (digital sensors, imaging plates, 2D and 3D bitewing radiographs) and 3D methods (high and low dose CBCT) were taken. Carious lesions were evaluated on 96 teeth at three positions (mesial, distal, and occlusal) and scored according to their level of demineralization by ten observers, resulting in 35,799 possible lesions across all observers and settings. For reference, µCT scans of all teeth were performed.

Results

Overall, radiographic evaluations showed a high rate of false-negative diagnoses, with around 70% of lesions remaining undetected, especially enamel lesions. BW + showed the highest sensitivity for dentinal caries and had comparatively high specificity overall.

Conclusions

Within the limits of the study, BW + showed great potential for added diagnostic value, especially for dentinal caries. However, the tradeoff of diagnostic benefit and radiation exposure must be considered according to each patient’s age and risk.

期刊介绍: As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
