摘要

背景:评价在不同管电压和/或管电流设置下获得的数字全景x线片诊断种植体周围骨缺损严重程度的准确性。材料与方法:将种植体置入29块牛肋块中,制备两种不同大小的种植体周围骨缺损(1型和2型)。在八种不同的管电压和/或管电流设置下获得所有肋块的数字全景x线照片。植入图像分别裁剪。采用Adobe Photoshop CC软件对裁剪后图像的平均强度值(AIV)进行分析。采用Kruskal-Wallis H检验比较aiv。所有裁剪的图像都使用李克特五点量表评估骨缺损缺失或存在的可能性。计算加权kappa值以比较观察者的一致性,并进行ROC分析以确定适当的暴露参数。结果:72 kV/6.3 mA时AIV最低(92.162±16.016),60 kV/3.2 mA时AIV最高(179.050±13.823)。根据暴露参数,Kruskal-Wallis H试验显示aiv有显著差异(p结论:在日常临床常规中,可以通过获得的全景x线片评估种植体周围骨缺损,并测试所有kV和mA值。然而,为了避免误诊和提高准确性,应使用适合患者的高kV和低mA水平的全景x线片,特别是在检测小或初始骨缺损时。

Evaluation of the different exposure parameters for the accurate diagnosis of peri-implantitis severity in digital panoramic radiography.

Evaluation of the different exposure parameters for the accurate diagnosis of peri-implantitis severity in digital panoramic radiography.

Evaluation of the different exposure parameters for the accurate diagnosis of peri-implantitis severity in digital panoramic radiography.

Evaluation of the different exposure parameters for the accurate diagnosis of peri-implantitis severity in digital panoramic radiography.

Background: To evaluate the accuracy of the diagnosis of peri-implant bone defects' severities in digital panoramic radiographs obtained at different tube voltage and/or tube current settings.

Material and methods: Two different sizes of peri-implant bone defects (type 1 and type 2) were prepared after the implants were inserted into 29 bovine rib blocks. Digital panoramic radiographs were obtained at eight different tube voltage and/or tube current settings for all rib blocks. Implant images were cropped separately. The average intensity value (AIV) of cropped images were analyzed using Adobe Photoshop CC software. The Kruskal-Wallis H test was used to compare AIVs. All cropped images were evaluated using a five-point Likert scale for the likelihood of a bone defect being absent or present. The weighted kappa values were calculated to compare observer agreement and ROC analysis was performed to determine the appropriate exposure parameters.

Results: The lowest AIV was obtained at 72 kV/6.3 mA (92.162±16.016), and the highest AIV was obtained at 60 kV/3.2 mA (179.050±13.823). The Kruskal-Wallis H test showed significant differences in the AIVs according to the exposure parameters (p<0.001). The kappa coefficient for the inter-observer agreement was excellent (0.864, p<0.001). The AUC values for type 1 defects ranged from 0.778 and 0.860; for type 2 defects ranged from 0.920 and 0.967. The AUC value of type 1 defects was slightly better in panoramic images obtained with high kV and low mA levels (72 kV/3.2 mA), compared to others.

Conclusions: In daily clinical routine, peri-implant bone defects might be evaluated by panoramic radiographs obtained with all kV and mA values tested. However, to avoid misdiagnosing and for better accuracy, panoramic radiographs obtained with high kV and low mA levels suitable for patients should be used, especially in the detection of small or initial bone defects.
