Abstract

Objectives: This in vitro study evaluated the diagnostic potential of short-wave infrared reflection (SWIRR) at 1050 and 1550 nm for proximal caries detection from the occlusal, buccal and lingual surfaces of posterior teeth under clinically relevant conditions. Bitewing radiography (BWR) was the alternative index test and micro-computed tomography (μCT) the reference standard.

Methods: 250 proximal surfaces of extracted human teeth were examined using SWIRR at 1050 and 1550 nm and BWR. SWIRR, BWR and μCT findings were evaluated twice by two trained examiners. SWIRR images were evaluated from occlusal and trilateral (occlusal, buccal and lingual combined) views. Sensitivity, specificity and AUC were calculated. Reliability assessment was performed using κ statistics.

Results: SWIRR (1050 nm) showed sensitivity of 0.44 for occlusal and 0.55 for trilateral assessment, paired with specificity of 0.96 and 0.90, whereas SWIRR (1550 nm) showed sensitivity of 0.73 and 0.85 paired with specificity of 0.76 and 0.59. Compared to occlusal view, trilateral SWIRR view revealed ≈10% higher sensitivity and lower specificity. BWR revealed lowest sensitivity (0.30) and highest specificity (0.99). Over-and underestimation of caries demonstrated opposite trends: from 1050-1550 nm, overestimation of trilateral SWIRR increased (0.08-0.29), while underestimation decreased (0.15-0.06).

Conclusion: Trilateral SWIRR has higher sensitivity and lower specificity for proximal caries, than occlusal SWIRR. 1050 nm are more suitable for trilateral SWIRR and 1550 nm for occlusal examinations. A combination of SWIRR at 1050 and 1550 nm may exhibit a balanced sensitivity and specificity for proximal caries.

利用波长为 1050 和 1550 纳米的三边短波红外反射进行体外早期近端龋齿检测。
研究目的这项体外研究评估了波长为 1050 和 1550 纳米的短波红外反射(SWIRR)在临床相关条件下从后牙的咬合面、颊面和舌面检测近端龋病的诊断潜力。方法:使用波长为 1050 和 1550 纳米的 SWIRR 以及 BWR 检查了 250 颗拔牙的近端表面。由两名训练有素的检查员对 SWIRR、BWR 和 μCT 结果进行两次评估。从咬合和三边(咬合、颊和舌结合)视图对 SWIRR 图像进行评估。计算灵敏度、特异性和 AUC。使用κ统计量进行可靠性评估:SWIRR(1050 nm)对咬合和三侧评估的灵敏度分别为 0.44 和 0.55,特异性分别为 0.96 和 0.90,而 SWIRR(1550 nm)对咬合和三侧评估的灵敏度分别为 0.73 和 0.85,特异性分别为 0.76 和 0.59。与咬合视图相比,三边 SWIRR 视图的敏感性高出≈10%,特异性则较低。BWR显示出最低的灵敏度(0.30)和最高的特异性(0.99)。龋齿的高估和低估表现出相反的趋势:从 1050-1550 纳米,三侧 SWIRR 的高估率增加(0.08-0.29),而低估率降低(0.15-0.06):结论:与咬合SWIRR相比,三侧SWIRR对近端龋的敏感性更高,特异性更低。1050 nm 更适合三侧 SWIRR,1550 nm 更适合咬合检查。将 1050 纳米和 1550 纳米的 SWIRR 结合使用,可以平衡近端龋的灵敏度和特异性。

期刊介绍: Dentomaxillofacial Radiology (DMFR) is the journal of the International Association of Dentomaxillofacial Radiology (IADMFR) and covers the closely related fields of oral radiology and head and neck imaging. Established in 1972, DMFR is a key resource keeping dentists, radiologists and clinicians and scientists with an interest in Head and Neck imaging abreast of important research and developments in oral and maxillofacial radiology. The DMFR editorial board features a panel of international experts including Editor-in-Chief Professor Ralf Schulze. Our editorial board provide their expertise and guidance in shaping the content and direction of the journal.
