High-quality photos are critical for the remote diagnosis of dental trauma and thus are beneficial to the prognosis. The quality of the images obtained using a cell phone depends on the level of dental and photography knowledge of the person who is taking the photos.
This study aimed to determine the efficacy of photography education in improving images used for the remote diagnosis of dental trauma.
The subjects comprised 30 laypeople and 30 dentists who were randomly assigned to 15 subgroups with 2 subjects in each. Each subject was asked to take photos of their own anterior teeth and those of their partner on the assumption that an accident occurred using both an iPhone 4s and iPhone 6. Education about how to take an appropriate photo of the anterior teeth for teleconsultation purposes was then provided, after which photos were taken again. Photos were assessed by a dentist for their usefulness in diagnosis.
This study analyzed 965 photos: 441 taken by laypeople and 524 taken by dentists. Photos taken after providing education had significantly higher scores for all assessment items than those taken before education (P<.05). The scores were also significantly higher for photos taken using the rear camera than those taken using the front camera (P<.02). The iPhone 6 did not have overwhelming advantages. The photos taken by dentists had significantly higher scores than those taken by laypeople for most of the evaluated items.
Both laypeople and dentists might find photography education useful for when they are taking photos to be used in teleconsultations. The type of cell phone does not significantly affect the usefulness of such photos.
高质量的照片对于牙科外伤的远程诊断至关重要，因此有利于预后。使用手机获取的图像质量取决于拍摄照片的人对牙科和摄影知识的掌握程度。
本研究旨在确定摄影教育在提高用于远程诊断牙科外伤的图像质量方面的效果。
研究对象包括 30 名非专业人士和 30 名牙医，他们被随机分为 15 个小组，每组 2 人。每个受试者都被要求使用 iPhone 4s 和 iPhone 6 拍摄自己和同伴的前牙照片，假设发生了意外。然后提供有关如何为远程咨询目的拍摄适当的前牙照片的教育，之后再次拍摄照片。由一名牙医评估照片在诊断中的有用性。
本研究共分析了 965 张照片：441 张由非专业人士拍摄，524 张由牙医拍摄。提供教育后拍摄的照片在所有评估项目中的得分均明显高于教育前拍摄的照片（P<.05）。使用后置摄像头拍摄的照片得分也明显高于使用前置摄像头拍摄的照片（P<.02）。iPhone 6 并没有明显的优势。牙医拍摄的照片在大多数评估项目中的得分明显高于非专业人士拍摄的照片。
非专业人士和牙医在拍摄用于远程咨询的照片时都可能会发现摄影教育很有用。手机类型不会显著影响此类照片的有用性。
