Dental Radiology and Enterprise Imaging
What is Dental Radiology?
Imaging is an important tool in dentistry and part of the enterprise imaging ecosystem. Dental radiology is the most commonly used form of medical imaging in dentistry and enables dentists and oral surgeons to examine precise images of teeth, jaws, and surrounding structures using a small amount of radiation to detect used to detect cavities, bone loss, impacted teeth, periodontal diseases, tumors, and other issues in addition to monitoring the process of dental treatment orthodontics, or root canal therapy. In 2018, over 1.4 billion dental X-rays were performed in the United States with procedure types ranging from more classic intraoral and extraoral X-rays to newer cone beam computed tomographies (CBCTs) with over 90% in the intraoral X-ray category.
What are the types of imagery used in Dental Radiology?
The two types of imagery commonly used in dentistry are Cone-beam computed tomography (CBCT) and Digital Radiology. CBCT is particularly useful in implant dentistry, oral surgery, and orthodontics and produces 3D images of the teeth, jaw, and surrounding structures, providing more detailed images for the diagnosis, treatment planning, and monitoring of progress. Digital radiography is a newer technique that uses digital sensors and a low dose of radiation to capture images. This approach offers higher-resolution image quality and the ability to share images with other clinicians.
Intraoral cameras involve inserting small cameras into the mouth that can capture detailed images of the teeth and gums and are sometimes used in dental imaging. These cameras are used to detect cavities, periodontal disease, and other oral health issues and to show patients the condition of their teeth, which can help them make informed treatment decisions.
How large is the Dental Radiology segment?
Dental radiology is a substantial part of the medical imaging market and was valued at USD 1,487 million in 2021 according to Straits Research. It is expected to reach USD 12,511 million by 2030. North America accounts for the largest share of the market.

What types of enterprise imaging workflows are related to Dental Radiology?

Digital Imaging and Communications in Medicine (DICOM) is the standard for the communication and management of medical imaging information and related data. DICOM is most commonly used for storing and transmitting medical images enabling the integration of medical imaging devices such as scanners, servers, workstations, printers, network hardware, and PACS (picture archiving and communication systems) from multiple manufacturers. DICOM is critical in streamlining workflows, improving the accuracy and efficiency of diagnoses, and enabling better patient care. DICOM systems support dental radiology workflows including
- Image acquisition involves initially capturing dental images through various modalities such as traditional X-rays, CBCT, digital radiography, and intraoral cameras.
- Image management includes storing, organizing, managing, and tagging the captured images with patient information, securing the images, and ensuring that they are accessible to authorized users.
- Image interpretation analyzes the images to properly diagnose, plan treatment, and monitor the progress of dental patients.
- Image distribution ensures images are secure and available to authorized users within the healthcare organization. This can include sharing the images with other dentists, oral surgeons, and specialists, as well as providing the images to patients and their families.
- Image archiving entails storing images of images for long-term retention, which can be used for future reference and follow-up.
How are dental images stored?
- Dedicated “standalone” systems, often based around a personal computer and used for single-modality applications such as a single intraoral camera or a single CCD x-ray detector. These systems have a method for short-term and long-term storage, and the ability to print good-quality images. However, connectivity and communication with other systems are limited.

- Enterprise imaging systems allow for the integration of different modalities and provide a centralized location for accessing and managing images. Dedicated systems for each function allow multi-modality and multiple users to share the same system. This type of system, commonly known as PACS or MIMPS, is usually installed in larger institutions. A VNA is often deployed when there is a multi-department, multi-specialty, or enterprise scenario.

Dental Radiology and VNAs
A VNA consolidates all imaging data from multiple systems, departments, facilities, and vendors into a centralized access point serving as a single source of truth for patient imaging information. VNAs can store and display any file format, images, or multimedia content, DICOM or non-DICOM, as well as retrieve data in its native format. The VNA can also act as a workflow engine by creating a DICOM Modality Worklist to, route, prefetch, and send notifications. Today, VNA needs to support DICOMweb and FHIR connectivity and provide various APIs to deliver the data in and out of the VNA reliably and efficiently. Dental radiology can use a VNA as part of their enterprise imaging workflow to store and manage images from various modalities used in dental radiology, such as traditional X-rays, cone-beam computed tomography (CBCT), digital radiography, and intraoral cameras. This allows for the integration of different types of images and makes them accessible from one location.
Additionally, a VNA can be integrated with other clinical systems such as dental practice management software, electronic health records, and picture archiving and communication systems (PACS) which can improve the overall efficiency and quality of care for dental patients. And it can also support the distribution of images to authorized users within the healthcare organization, such as other dentists, oral surgeons, and other specialists. Helping to improve collaboration among healthcare professionals and enhance the diagnostic and treatment capabilities of the dental team.
Configuring dental devices for a VNA
Relevant priors, such as previous dental examinations, oral surgeries, or imaging studies, are crucial in interpreting current dental images, providing additional context, and differentiating between new changes and longstanding findings. It is essential to ensure that the VNA provides a query retrieve proxy to allow devices to access the images stored in it. This is especially important when numerous devices, ranging from hundreds to thousands, access these images frequently for reference and comparison. The query retrieves proxy and enables these devices to query multiple sources, including the VNA, thereby facilitating easier access to the relevant data. If these images are stored in the VNA, there might be hundreds, or even thousands, of devices pulling these images every minute. Ensuring the VNA can support and provide a query retrieve proxy to allow those devices to query multiple sources is critical to streamlining imaging workflows to provide timely patient care.
AE Title lists the title of the device’s DICOM application entity and is set by the device’s system administrator which associates the AE Title with the IP address. The IP access lists with DHCP support help ensure device querying is possible. Some panoramic studies have to be stored for a long period, so the ability to use multiple tiers of storage such as hot, warm, and cold is a crucial aspect of the process. Optimizing transmission and storage can be achieved by compressing on the fly.
