This chapter provides a comprehensive detail about dental radiographic imaging, emphasizing both foundational principles and modern advancements. It introduces major dental imaging modalities including intraoral radiographs, panoramic radiographs (OPG), cephalometric radiographs, and cone-beam computed tomography (CBCT), detailing their clinical relevance and technical operation. A historical overview of dental X-ray equipment provides the evolution from conventional film-based systems to digital and 3D imaging technologies. The chapter delves into the instrumentation and working principles of intraoral units, panoramic systems, and cephalometric devices, including configurations such as handheld and wall-mounted scanners. It further explains basic intraoral techniques such as bitewing, periapical, and occlusal X-rays as well as image formation processes in panoramic and cephalometric radiography. An in-depth discussion on CBCT technology outlines its development, technical differences from conventional CT (MSCT), and its expanding role in dental diagnostics and treatment planning. Additionally, the chapter emphasizes the importance of quality control, acceptance testing, and routine equipment checks to ensure image accuracy and patient safety. It concludes with key considerations for radiation dose management, regulatory compliance, and safety practices for dental professionals in delivering safe and effective radiological care.
