What Happens to Your CBCT Data? Understanding Dental PACS and Data Security
“Your CBCT scan data is stored on a secure, encrypted cloud PACS (Picture Archiving and Communication System). It is accessible only to authorised clinicians and yourself. At DMD Imaging, images are retained for a minimum period in line with medical record guidelines, and digital access can be shared with your treating dentist or specialist without physically handing over a CD. ”
You have just had a CBCT scan. The machine rotates, the software reconstructs, and within minutes there is a detailed three-dimensional map of your jaw on the screen. The radiologist reviews it. A report is prepared. And then you might wonder: where does all of that go?
It is a fair question, and not enough patients or even referring dentists ask it.
Your dental imaging data is medical data. It contains detailed anatomical information. It has a long clinical lifespan — images taken today may be directly relevant to treatment decisions five or ten years from now. How it is stored, who can access it, and how long it is kept are not administrative details. They are part of your care.
What Is Dental PACS?
PACS stands for Picture Archiving and Communication System. It is the infrastructure that stores, organizes, and distributes medical images — in dental context, that includes CBCT scans, OPGs, periapical X-rays, and any other digital imaging.
Think of it as a secure, structured library for radiographic data. Rather than burning images onto a CD and handing it across a counter — which was standard practice until recently and still happens in many places — PACS keeps your images in a central, accessible repository that authorized users can access from anywhere.
In a cloud-based PACS, that repository is hosted on secure remote servers rather than on a hard drive in the clinic. This is an important distinction.
| Feature | Cloud Dental RIS PACS | Local/CD Storage |
|---|---|---|
| Data backup | Automatic, redundant cloud backup | Single physical copy |
| Access for your dentist | Instant digital share link | Patient carries CD manually |
| Risk of data loss | Near-zero with cloud redundancy | CD damage, loss, or corruption |
| Image quality | Full-resolution DICOM files | Sometimes compressed exports |
| Long-term storage | Managed retention policy | No retention after patient leaves |
| Access from multiple locations | Yes — specialist, surgeon, orthodontist can all access | Physical handoff required |
| Environment friendly | Does not add to environmental waste | Generates plastic and electronic waste |
Your CBCT Data: What It Contains and Why It Matters
A CBCT scan generates DICOM files — Digital Imaging and Communications in Medicine. These are not ordinary image files. A single CBCT study can contain hundreds to thousands of individual slice images, each carrying embedded metadata: patient name, date of birth, scan parameters, the imaging centre's details, and the acquisition settings.
This data has a long clinical shelf life. A CBCT taken before implant placement may be referenced during a complication review years later. A scan taken for one purpose — say, orthodontic planning — may contain incidental findings relevant to future treatment. Bone levels, sinus anatomy, nerve canal position: these are relatively stable anatomical features that do not need to be re-imaged every time if a previous quality scan exists.
Which is exactly why proper, long-term, accessible storage is not just convenient — it is clinically meaningful.
How Is the Data Secured?
This is where cloud PACS earns its place. Security in medical imaging storage operates at several layers.
Encryption
DICOM files stored in a modern cloud PACS are encrypted both in transit (when being transmitted from the scanner to the server) and at rest (when sitting on the server). This means that even if someone were to intercept the data or gain unauthorised access to the server infrastructure, the files would be unreadable without the decryption keys.
Access Controls
Data is accessible only to authenticated, authorised users. At DMD Imaging, that means the radiologist reviewing your scan, the administrative team managing your record, and — when you or your treating clinician requests it — your referring dentist or specialist. Nobody else.
Each access event is logged. Systems maintain an audit trail of who accessed which images and when. This is not just good practice — it is a requirement under any responsible medical data governance framework.
Physical and Infrastructure Security
Cloud storage infrastructure used by healthcare systems operates under strict physical and digital security protocols — redundant data centres, regular security audits, and uptime guarantees that no clinic-based hard drive can match. The days of important patient data sitting on a local server that nobody backs up, in a clinic that gets flooded, are precisely what cloud PACS is designed to eliminate.
“At DMD Imaging every CBCT scan is stored on a cloud PACS system. Images are encrypted, backed up automatically, and accessible only to authorised parties. You will never be handed a CD and told to keep it safe — your data is kept safe for you. ”
How Long Are Your Images Kept?
Medical record retention periods in India are governed by the Clinical Establishments Act and related state-level regulations, as well as the Medical Council of India guidelines. For dental imaging, records including radiographs should generally be retained for a minimum of three years for adult patients, and until the patient reaches adulthood plus three years for minors — though many centres, and professional best practice, recommend longer retention periods.
At DMD Imaging, images are retained in line with applicable guidelines, with the practical aim of keeping records accessible for as long as they may be clinically relevant. For implant cases, orthodontic records, or patients with complex histories, this may mean images are stored and accessible for many years.
The question of how long images are kept matters for one very practical reason: if you change dentists, move cities, or need a second opinion years from now, your images should still be there — retrievable, full-resolution, and usable. Paper notes fade. CDs scratch. Cloud-stored DICOM data, managed properly, does not.
Who Can Access Your Data — and Who Cannot?
Your imaging data belongs to you. A clear access framework should govern it.
You can request your own images and report at any time. At DMD Imaging, this is straightforward — images can be shared digitally with you directly.
Your referring dentist or implantologist receives the report and, where clinically appropriate, a DICOM image share link — so they have full-resolution data, not a printout.
Other specialists involved in your care — an oral surgeon, an orthodontist, a prosthodontist — can be granted access if you are being co-managed across clinicians.
Third parties — insurance companies, other organisations — do not have access without your explicit consent.
This is standard medical data governance, applied to dental imaging. What makes cloud PACS a genuine improvement over legacy systems is not just the security — it is the ease of legitimate, controlled access. Sharing your imaging data with a new specialist used to mean carrying a CD across town. Now it means sending a secure link.
What About the Radiologist's Report — Is That Stored Separately?
Yes. The written radiological report — the document prepared by the radiologist after reviewing your scan — is a separate clinical record from the images themselves. Both are stored and both are part of your medical record.
At DMD Imaging, every CBCT scan is reviewed and reported by a qualified oral and maxillofacial radiologist doctor. The report is not generated by software. It is written by a specialist who has examined the scan in multiple planes, cross-referenced clinical findings, and documented measurements, observations, and recommendations. That report is stored alongside your imaging data and is accessible to your treating clinician in the same way the images are.
The distinction matters because a DICOM file alone — without a proper radiological report — is raw data. It requires clinical interpretation. The report is the interpretation, authored by a qualified specialist, and it has the same longevity and accessibility as the images.
Questions Worth Asking Before Your Scan
Whether you are a patient or a referring dentist, these are reasonable things to ask any imaging centre about their data practices:
Is my data stored on a cloud PACS or local storage — and is it backed up?
Are images encrypted in transit and at rest?
How long are images retained, and what is the process for requesting access later?
How is my imaging shared with my referring dentist — CD, compressed file, or full DICOM access?
Who reviews the scan — a radiologist doctor, or is reporting automated?
Is there an audit trail of who has accessed my data?
These are not difficult questions. Any imaging centre with proper data practices should be able to answer all of them clearly. If they cannot — that tells you something too.
The Bigger Picture: Why Data Security Is Part of Clinical Quality
Dental CBCT data security is not a separate concern from clinical quality. It is part of it.
A scan stored carelessly — on a CD that gets lost, on a local drive that fails, on a system without access controls — is a scan that may not be available when it is needed. A report that cannot be retrieved when a complication arises years later is a report that effectively does not exist. And imaging data that can be accessed by unauthorised parties is a breach of patient privacy that undermines the trust that medical care depends on.
Cloud PACS, done properly, solves all of these problems at once. It keeps data safe, keeps it accessible to those who should have it, and keeps it inaccessible to those who should not. At DMD Imaging in Delhi, this is the infrastructure behind every CBCT scan — not because it is a selling point, but because it is how medical imaging data should be managed.
When you leave after your scan, your data does not disappear into a disc in your bag or a filing cabinet somewhere. It is encrypted, stored, backed up, and ready — for your implantologist planning your surgery next week, and for whatever clinical need might arise years from now.

Frequently Asked Questions
-
Yes. You have the right to your own medical imaging data. Contact DMD Imaging and we will arrange secure digital access to your DICOM files and radiological report.
-
DICOM (Digital Imaging and Communications in Medicine) is the universal format for medical images. Unlike a JPEG or PNG, a DICOM file carries both the image data and embedded clinical metadata — patient information, scan parameters, institution details. It is the standard format used by all radiology systems, and it is what your CBCT data is stored as.
-
No. Your imaging data is shared only with your referring clinician and, where relevant, specialists involved in your care — and only with appropriate authorisation. Third parties do not have access.
-
Your data stays stored at DMD Imaging and is accessible to you. You can request a digital share of your images and report to provide to a new treating clinician at any time. You are not starting from scratch — your imaging history is preserved.
-
A CD gives you a physical copy of your images at one point in time. If it is scratched, lost, or formatted in a way your dentist's software cannot read, that data is gone. A cloud PACS stores a permanent, backed-up, encrypted copy that authorised parties can access digitally — at full resolution — whenever it is needed.
