Abstract

Purpose: To evaluate the influence of imaging compression on radiographic diagnosis of periodontal bone loss on smartphones.

Methods: 45 digital periapical radiographs with diverse periodontal bone loss patterns were selected. All radiographs were performed with a CMOS-type sensor and were exported from the acquisition software with two compressions: JPEG with a 10% compression rate and JPEG with a 90% compression rate. Images were shared using the WhatsApp application and three examiners evaluated all radiographs on the smartphone. The examiners' diagnostic agreement was evaluated using the Kappa index. The McNemar and Cochran's Q statistical tests were used to compare the impact of the image compression, examiner, and type of periodontal bone defect on the diagnosis. Statistical analysis was performed using the SPSS software.

Results: Kappa values were greater than 0.7 for all examiners and no statistically significant difference for the periodontal diagnosis, regardless of the image compression, the examiner background, and the type of periodontal bone defect.

Clinical significance: The use of smartphones to analyze and share images has become very common in dentistry. This study shows that images can be shared and analyzed on smartphones without compromising periodontal diagnosis, regardless of their spatial resolution.

文件压缩对智能手机牙周骨质流失放射诊断的影响。

目的：评估成像压缩对智能手机牙周骨质流失放射诊断的影响。方法：选取 45 张具有不同牙周骨质流失模式的数字根尖周X光片。所有X光片均使用CMOS型传感器拍摄，并通过两种压缩方式从采集软件导出：JPEG压缩率为10%，JPEG压缩率为90%。图像通过 WhatsApp 应用程序共享，由三名检查员在智能手机上对所有射线照片进行评估。检查人员的诊断一致性采用 Kappa 指数进行评估。McNemar 和 Cochran's Q 统计检验用于比较图像压缩、检查者和牙周骨缺损类型对诊断的影响。统计分析使用 SPSS 软件进行：结果：所有检查者的 Kappa 值均大于 0.7，且无论图像压缩程度、检查者背景和牙周骨缺损类型如何，牙周诊断结果均无显著统计学差异：使用智能手机分析和共享图像在牙科中已非常普遍。这项研究表明，无论图像的空间分辨率如何，在智能手机上共享和分析图像都不会影响牙周诊断。
