Understanding Digital Dental Imaging
By EGO Dental Clinic – Victoria, Central London
Dental X-rays remain one of the most important tools in modern preventive dentistry. They allow dentists to detect problems that may not be visible during a routine examination, often identifying issues early before they become painful, more complex, or more expensive to treat.
At EGO Dental Clinic in Victoria, we use modern digital imaging systems including MyRay digital X-rays, OPG panoramic imaging, and CBCT 3D scanning technology to provide detailed diagnostics while keeping radiation exposure as low as reasonably achievable in accordance with current UK dental radiography guidelines.
Why Are Dental X-Rays Important?
Many dental problems begin silently beneath the surface.
Modern dental imaging helps dentists diagnose:
• Tooth decay between teeth
• Hidden infections
• Bone loss and gum disease
• Cracks and fractures
• Wisdom tooth position
• Root canal problems
• Dental abscesses
• Implant planning requirements
• Orthodontic assessments
• Jaw and sinus evaluation
Early diagnosis is one of the key foundations of preventive dentistry and minimally invasive treatment.
Are Modern Dental X-Rays Safe?
Modern digital dental X-rays use extremely low levels of radiation compared to older film systems.
Digital technology has significantly reduced exposure levels while improving image quality and diagnostic accuracy.
Current dental radiography follows the internationally recognised ALARA principle:
“As Low As Reasonably Achievable.”
This means:
• X-rays are only taken when clinically justified
• Exposure settings are minimised
• Modern low-dose digital systems are used
• Images are tailored to the patient’s needs
All dental radiographs in the UK must comply with strict IR(ME)R radiation regulations and professional safety standards.
How Much Radiation Do Dental X-Rays Use?
One of the most common concerns patients have is radiation exposure. In reality, modern dental X-rays involve very small doses of radiation.
Approximate modern digital dental imaging doses may include:
• Single small dental X-ray (bitewing/periapical): approximately 1–5 microsieverts
• Digital OPG panoramic scan: approximately 10–30 microsieverts
• Small field CBCT scan: approximately 20–200 microsieverts depending on settings and scan size
For perspective:
• Average natural background radiation in the UK is approximately 2,700 microsieverts per year
• A short airline flight may expose a person to similar or greater radiation than some dental imaging procedures
• Modern digital systems may use significantly lower doses compared to older film-based technology
Radiation exposure varies depending on:
• Equipment used
• Image size
• Patient anatomy
• Scan settings
• Clinical requirements
What Is a MyRay X-Ray System?
At EGO Dental Clinic, we use advanced MyRay digital imaging technology for both conventional dental radiographs and CBCT 3D imaging.
MyRay systems are designed to provide:
• High-definition imaging
• Low-dose digital exposure
• Faster image acquisition
• Enhanced diagnostic detail
• Improved patient comfort
• Modern 3D treatment planning capabilities
These systems assist clinicians in diagnosing conditions more accurately while maintaining a strong focus on radiation safety.
What Is an OPG Scan?
An OPG (orthopantomogram) is a panoramic dental X-ray showing:
• Upper and lower teeth
• Jaw bones
• Wisdom teeth
• Sinuses
• Jaw joints
OPG imaging is commonly used for:
• Wisdom tooth assessment
• Orthodontic planning
• Implant consultations
• General oral health screening
• Bone evaluation
The scan is quick, comfortable, and non-invasive.
What Is CBCT?
CBCT stands for Cone Beam Computed Tomography.
Unlike standard dental X-rays, CBCT creates a detailed 3D image of the teeth, bone, nerves, and surrounding anatomy.
CBCT technology is commonly used in:
• Dental implant planning
• Complex root canal assessment
• Oral surgery
• Wisdom tooth evaluation
• TMJ assessment
• Advanced diagnostics
Modern CBCT systems allow clinicians to visualise anatomy with significantly greater detail compared to traditional 2D imaging.
When Are Dental X-Rays Needed?
Dental X-rays are only recommended when clinically appropriate.
Your dentist may advise imaging for:
• New patient examinations
• Dental pain
• Swelling or infection
• Decay assessment
• Monitoring bone levels
• Implant planning
• Trauma or injury
• Wisdom teeth
• Orthodontics
• Root canal treatment
Frequency varies depending on:
• Oral health risk
• Decay risk
• Gum health
• Symptoms
• Previous dental history
Dental X-Rays & Pregnancy
Patients should always inform their dentist if they are pregnant or may be pregnant.
Modern dental X-rays involve very low doses, but imaging is only carried out during pregnancy when clinically justified and appropriate precautions are followed in line with current guidelines.
Common Myths About Dental X-Rays
“Dental X-rays are dangerous.”
Modern digital dental imaging uses extremely low radiation doses and follows strict safety protocols.
“You should avoid all X-rays.”
Avoiding clinically necessary X-rays may delay diagnosis and treatment of hidden disease.
“CBCT always means high radiation.”
Modern CBCT systems vary greatly in dose depending on field size and settings. Small-field, focused scans may significantly reduce exposure compared to older technologies.
Modern Dentistry Relies on Early Diagnosis
One of the biggest advances in modern dentistry is the ability to diagnose problems earlier and more conservatively.
Digital imaging allows dentists to:
• Detect issues sooner
• Monitor progression accurately
• Improve treatment planning
• Reduce unnecessary invasive treatment
• Preserve natural tooth structure where possible

Final Thoughts
Modern dental X-rays play a vital role in preventive and minimally invasive dentistry. Advances in digital imaging technology have significantly improved image quality while reducing radiation exposure compared to older systems.
When clinically justified and appropriately used, dental radiographs help dentists detect disease earlier, improve treatment accuracy, and support long-term oral health.
