How We Define Digital Quality Assurance
Clinics that adopt a proper robust digital quality assurance (DQA) approach often see improvements in customer satisfaction and loyalty, as well as reductions in complaints, future lawsuits, and optimal recommended treatment plans.
DQA can also help to improve operational efficiency and reduce costs by identifying and resolving quality issues before they cause delays or errors when making recommended treatment plans.

Dental X-Ray Quality Assurance Requirements
Quality assurance rules for dental X-ray equipment are set locally, so they differ by country and often by state or province. Most follow the same pattern.
National guidance
A national health or radiation authority publishes recommended safety procedures for dental radiography.
Regional rules
States, provinces and dental licensing bodies decide which requirements are enforced and how facilities are inspected.
Your regulator
The body that licenses your X-ray equipment or your practice sets the testing and record-keeping rules you must follow.
Health Canada's Safety Code 30 (2022) is national guidance on radiation protection in dentistry. It becomes a legal requirement where an authority references it. Each province then sets its own enforceable rules. In Ontario, the HARP Act and Regulation 543 apply, and the Royal College of Dental Surgeons of Ontario (RCDSO) summarizes them for dentists.
What a Dental X-Ray QA Program Includes
The details vary by regulator, but national guidance such as Health Canada's Safety Code 30 describes the same core elements for digital dental imaging.
Acceptance testing
Before any clinical use of new, modified or repaired equipment, to set baseline values.
Routine quality control
Daily, monthly and annual tests to confirm the equipment still performs as it did at baseline.
Test tools or phantoms
Recommended for daily and monthly QC, and ideally purchased along with the X-ray unit.
QA records
Documentation of QA activities and equipment performance, kept for the period your regulator requires.
Retake analysis
Rejected images kept for routine review, with the cause investigated before a patient is re-exposed.
ALARA
Keeping patient dose as low as reasonably achievable, every day.
Regional rules can add specific record-keeping duties. Ontario's, for example, call for a daily count of images taken on each machine, a daily retake log with reasons and corrective action, and six years of records, for panoramic as well as intraoral units.

How Phantom XY and Phantom Cloud Cover It
One two-minute test per device, with the records your inspector asks for kept automatically.
Phantom XY supports your routine QA program. Acceptance testing and annual tests by a qualified tester remain separate requirements.
Common Questions About Dental X-Ray QA
Do digital dental X-rays need daily quality assurance?
Often, yes. Requirements depend on where you practise, but daily quality control is common for digital radiography. Health Canada's Safety Code 30 includes daily QC in its QA program, and some regulators, such as RCDSO in Ontario, call for it on every day a machine is used. Check with your regulator.
Is a step wedge still needed for digital X-ray QA?
Step wedges were designed for film. Some regulators now state that a step wedge is not required for digital systems and that other digital QA tools may be used; RCDSO in Ontario is one example. Check what your regulator accepts.
Does QA apply to panoramic X-ray machines?
Yes. Safety Code 30 covers extra-oral units such as panoramic machines, and regional rules such as Ontario's apply their QA requirements to panoramic units too.
How long should dental X-ray QA records be kept?
It depends on your regulator; Ontario, for example, requires six years. Phantom Cloud stores test results and logs for 10 years.
Is Health Canada's Safety Code 30 the law?
Safety Code 30 is federal guidance. It becomes enforceable where an authority references it, such as federal workplace regulations or a provincial regulator. Each province sets its own enforceable rules.
