Dental Panoramic Scan

Introduction 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. Data Collection 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. Data Preprocessing 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. Data Description 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. 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.

数据集概述：本数据集包含1488张全景曲面断层影像（orthopantomogram, OPG），采集自印度某牙科诊所。所有影像均采用数字化OPG拍摄设备获取，该设备可呈现患者牙齿与颌骨的全景视图。为保护患者隐私，数据集已剔除所有个人身份信息，且本数据集未附带任何标签与标注内容。
数据采集：本数据集的OPG影像采集周期为六个月，来源为前往该牙科诊所接受常规口腔检查或就诊牙科专科病症的患者。影像通过数字化OPG设备拍摄，该设备借助X射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影像均经过质量与清晰度核验。存在模糊问题或图像伪影的影像已被剔除。此外，为进一步保障隐私，影像中所有患者个人信息均已被移除。
数据详情：本数据集共包含1488张JPEG格式的OPG影像，单张影像分辨率为2400×1200像素，为灰度图像。单张影像文件大小介于900KB至1.1MB之间，具体取决于影像内容的复杂度。本数据集的OPG影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，部分影像则展示了正常健康的牙齿与颌骨结构。
