Dental Panoramic Scan

Introduction <br> The dataset consists of 1488 orthopantomogram (OPG) images collected from a dental clinic in India. The images were taken using a digital OPG machine, which captures a panoramic view of the patient's teeth and jaws. The dataset does not contain any personal information about the patients, as it has been deleted for privacy reasons. Additionally, the data does not have any labels or annotations. <br> Data Collection <br> The OPG images were collected over a period of six months from patients who visited the dental clinic for routine check-ups or specific dental problems. The images were captured using a digital OPG machine that uses X-rays to create a panoramic view of the patient's teeth and jaws. The machine is designed to capture high-quality images with minimal radiation exposure to the patient. <br> Data Preprocessing <br> Before being added to the dataset, each OPG image was checked for quality and clarity. Images that were blurry or had artifacts were removed from the dataset. Additionally, all personal information about the patients was deleted from the images to ensure privacy. <br> Data Description <br> The dataset contains 1488 OPG images in JPEG format. Each image has a resolution of 2400 x 1200 pixels and is grayscale. The size of each image ranges from 900 KB to 1.1 MB, depending on its complexity. <br> The OPG images in this dataset show different types of dental problems such as cavities, gum disease, impacted teeth, and fractures. Some images also show normal healthy teeth and jaws.

引言
本数据集包含1488张采集自印度某牙科诊所的口腔全景X线片（orthopantomogram，OPG）。这些图像由数字化OPG设备拍摄，可获取患者牙齿与颌骨的全景视图。出于隐私保护需求，所有患者个人信息均已删除，因此本数据集不包含任何患者个人资料。此外，该数据集未附带任何标签或标注信息。

数据采集
本数据集的OPG图像采集周期为6个月，样本来源于前来该牙科诊所接受常规检查或针对性牙科诊疗的患者。所有图像均采用数字化OPG设备拍摄，该设备借助X线生成患者牙齿与颌骨的全景视图，其设计旨在以最低的患者辐射暴露量获取高质量影像。

数据预处理
在纳入数据集前，每一张OPG图像均经过质量与清晰度核查，模糊或存在影像伪影的图像已被移除。此外，为保障患者隐私，所有图像中的个人身份信息均已被彻底删除。

数据说明
本数据集包含1488张JPEG格式的OPG图像，单张图像分辨率为2400×1200像素，均为灰度图像。单张图像的文件大小介于900KB至1.1MB之间，具体大小取决于图像的复杂程度。

本数据集内的OPG图像涵盖多种牙科病症，包括龋病、牙周疾病、阻生齿及颌骨骨折等，部分图像则展示了健康的牙齿与颌骨结构。
