Abstract：
BACKGROUND: Diagnosis in dentistry begins with the correct reading and interpreting of the dental radiograph.
OBJECTIVE: The aim of the present study was to examine the effects of the imaging technique used, the dentistry specialty and the years of experience on the gray-level perception among dentists.
METHODS: A custom web application was developed. Dentomaxillofacial radiologists (DentRads), endodontists (Ends) and general dental practitioners (GDPs) were invited via e-mail to participate in the study. A total of 46 participants met the requirements of the test. The test comprised 2 webpages. On the 1st page, the participants were asked for information such as gender, specialty, the years of experience, and the imaging techniques they used. Then, on the 2nd page, they were welcomed with instructions and directions, and asked to rearrange 85 gray color tones represented by square bars of equal dimensions. These mixed gray bars were placed in 4 rows according to the principles of the FarnsworthMunsell 100-hue test (FM). Each clinician\'s test results were recorded in a database. The individual\'s level of recognition of gray tones was evaluated through the total error score (TES), which was calculated using a web-based independent scoring software program. Lower TES values were a desirable result, indicating fewer misplacement, while higher scores indicated more misplacements of gray tones. The testing time (TT) was recorded automatically.
RESULTS: The years of the participants\' experience as dentists or specialists did not affect TES or TT. The dentists who used the charge-coupled device-complementary metal oxide semiconductor (CCD-CMOS) had lower TES values than those who used analog radiographs (p < 0.05).
CONCLUSIONS: While the specialty and the years of experience did not affect the clinicians\' ability to recognize gray tones, the digital imaging techniques (photostimulable phosphor (PSP) and CCD/CMOS) could improve the clinicians\' gray-level perception.

摘要：
背景：牙科诊断始于正确阅读和解读牙科X光片。
目的：本研究的目的是检查所使用的成像技术的效果，牙科专业和多年的经验，在牙医之间的灰色感知。
方法：开发了一个自定义Web应用程序。牙颌面放射科医师(DentRads),通过电子邮件邀请牙髓医生(Ends)和普通牙科医生(GDP)参与研究.共有46名参与者符合测试要求。测试包括2个网页。在第一页，参与者被要求提供性别等信息，专业,多年的经验，以及他们使用的成像技术。然后，在第二页,他们受到了指示和指示的欢迎，并要求重新排列由相等尺寸的方条表示的85种灰色色调。根据FarnsworthMunsell100色调测试(FM)的原理,将这些混合的灰色条放置在4行中。每个临床医生的测试结果都记录在数据库中。通过总误差评分（TES）评估个体对灰色色调的识别水平，这是使用基于网络的独立评分软件程序计算的。较低的TES值是一个理想的结果，表明更少的错位，而更高的分数表明更多的灰色色调错位。自动记录测试时间(TT)。
结果：参与者作为牙医或专家的经验不影响TES或TT。使用电荷耦合器件互补金属氧化物半导体（CCD-CMOS）的牙医的TES值低于使用模拟射线照片的牙医（p<0.05）。
结论：虽然专业和多年的经验并不影响临床医生识别灰色调的能力，数字成像技术（光刺激荧光粉（PSP）和CCD/CMOS）可以改善临床医生的灰度感知。
