The Visionstar SJD-212 is a battery-powered dental X-ray generator for intraoral radiography at the point of care. The generator runs at 30 kHz, with tube voltage selectable at 60 or 70 kV, tube current selectable across 1.5, 2.0, 2.5 and 3.0 mA, and exposure timing from 0.1 to 2 seconds. Tube focus is specified at order as 0.4 mm or 0.8 mm.

The control face carries a small colour panel above a membrane keypad laid out with anatomical and patient-build icons. Selection by picture suits the way UK exposure protocols are written — a value per region, adjusted for patient size — and it gives every operator on a shared unit the same route to the same setting.

One question belongs in the specification conversation. The manufacturer's data sheet does not publish the values stored behind each icon, or say whether they can be edited. Ask at quotation, because your Medical Physics Expert needs to know whether factory values can be replaced with the exposure factors agreed for your local diagnostic reference levels. If they are fixed, that constrains how the unit fits your optimisation work.

Colour rendering does useful work on a panel of this size. Where limited area carries machine state, selected region and the active exposure value together, colour distinguishes those layers so the operator reads the right field first time.

The housing is shaped to sit in the palm, with the flat control face to the rear and a tapered nose forward. At 220 mm deep, the emitting end stands away from the hand while the mass stays close to the wrist, which supports a steady hold through the exposure.

Published distance from skin to cone is 130 mm — raise that with your Radiation Protection Adviser during specification, since UK dental guidance sets minimum focus-to-skin distances that differ above 60 kV, and this unit offers a 70 kV setting. Power comes from a DC 14.8 V 1600 mAh lithium pack, charged from AC 100–240 V with a DC 16.8 V output, rated at 100–300 VA. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-212 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-212 is configured for that daily volume. It supports bitewing caries detection, periapical assessment of pathology, endodontic working-length and obturation verification, alveolar bone-level review, and root morphology assessment ahead of extraction.

Paediatric and mixed dentition work is a clear fit. Anterior periapicals show retained deciduous teeth, delayed or ectopic eruption, supernumeraries such as a mesiodens, and the stage of developing successors. Those findings decide whether a child is monitored at recall, referred for extraction of a retained primary tooth, or referred to orthodontics. Community dental services carry much of that caseload, and reduced exposure factors for smaller patients belong in the protocol set agreed with a Medical Physics Expert.

Hygienist-led periodontal care uses bitewing and periapical views to show interproximal calculus deposits and alveolar bone levels following BPE screening. Radiographs read interproximal surfaces well and buccal or lingual deposits poorly, so they supplement probing and charting rather than standing in for them.

Endodontic practice makes heavy use of periapical views, with a single root canal treatment often needing a diagnostic film, a working-length film, a master cone check and a post-obturation view.

Community teams need equipment one clinician can carry. At 1.7 kg, the unit travels easily, though the modest published battery capacity makes spare pack availability worth settling before a domiciliary round or a screening session, with off-site radiation protection arrangements agreed with the RPA in advance.

Guidance from the College of General Dentistry and UKHSA Dental X-ray Protection Services remains the reference point UK practices work to, alongside HSE enforcement of IRR17.

Selection by picture

Anatomical and patient-build icons put the choice where the operator is already looking and give every clinician, therapist and nurse on a shared unit the same route to the same setting — which is what a documented protocol needs to be followed consistently.

Colour doing real work on a small panel.

Where limited area carries machine state, selected region and active exposure value together, colour separates those layers so the eye lands on the right field first time, with the unit already held in position.

Genuine headroom for smaller patients

The 0.1 second timing floor alongside the lower milliamp steps supports meaningfully reduced factors for children, agreed with your MPE and recorded in local diagnostic reference levels rather than approximated at the chair.

Mass at the wrist, beam well forward.

A rounded palm-held body with a 220 mm depth keeps the weight close to the wrist while the emitting end stands away from it, which supports a steady hold through the exposure across a full list.

An exposure envelope that spans the view set

Two kilovoltage settings and four milliamp steps let a protocol reach from anterior views on a child up to molar bitewings on a large adult, with values agreed by your MPE.

Carried by one clinician

At 1.7 kg, the unit sits comfortably within single-person handling for a full list, a community round or a screening session, alongside whatever else has to travel.

The preset question surfaced before order

Whether the stored icon values can be replaced with your agreed local diagnostic reference levels changes how the unit fits your optimisation work. Medigear.uk can arrange for the manufacturer to confirm that in writing with your quotation.

UK supply, commissioning and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance and quotations for the SJD-212 across the United Kingdom, including requesting the manufacturer's focus-to-skin, cone and filtration documentation.

Small colour display panel

A colour screen presents machine state, the current selection and the active exposure value as separate fields on one reading face.

Anatomical and patient-build icon keypad

The membrane keypad is laid out with region and build icons; confirm the stored values behind each key and whether they are user-editable at order.

Selectable tube voltage at 60 or 70 kV

Two kilovoltage settings support protocols that vary by region, patient build and the greyscale range a view requires.

Selectable tube current across four steps

Tube current is offered at 1.5, 2.0, 2.5 and 3.0 mA, giving a second exposure variable alongside kilovoltage and time.

0.1–2 second exposure timing

A twenty-fold span reaches direct digital sensors at the short end and phosphor storage plate or film technique at the upper limit.

Tube focus at 0.4 mm or 0.8 mm

Focus size is specified at order, one of the figures governing geometric sharpness at the receptor alongside working distance and receptor type.

30 kHz generator

High-frequency drive produces a steady output waveform through the exposure, supporting repeatable receptor density from one radiograph to the next.

130 mm published skin-to-cone distance

The manufacturer publishes a skin-to-cone figure; confirm with the manufacturer whether this is the focus-to-skin distance and which kilovoltage settings the supplied cone supports, and have your RPA review it.

Palm-held rounded housing

The body is shaped to sit in the palm, with the flat control face to the rear and a tapered nose forward of the hand.

220 mm housing depth

Published depth places the emitting end well forward of the operator's hand while the mass stays close to the wrist.

Ready and exposure indicators

Illuminated status markers signal machine state through the exposure cycle, giving visual confirmation at each stage.

Side-mounted exposure release

The exposure control sits on the side of the housing, within reach of the carrying hand while the head is held in position.

DC 14.8 V 1600 mAh lithium battery

An integrated lithium pack powers the unit away from a fixed power position, charged from AC 100–240 V with a DC 16.8 V output and a 100–300 VA rating.

Moulded hand strap and wipeable shell

An integrated strap supports single-hand carrying, and the sealed keypad and moulded housing present flat surfaces suited to routine surgical decontamination.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

The keypad is laid out with anatomical and patient-build icons, which indicate selection by region and build. The data sheet does not publish the exposure factors stored behind each key or state whether they are user-editable, and that is the single most important thing to settle before order. If the values can be loaded with your agreed local diagnostic reference levels, the interface becomes genuinely useful; if they are fixed at the factory, your Medical Physics Expert has to work around them. Ask for the answer in writing in the quotation. Medigear.uk can arrange for that detail to be requested from the manufacturer.

Layer separation where area is limited. Machine state, the selected region and the active exposure value all have to appear at once, and colour distinguishes them so the operator's eye lands on the right field the first time. That matters during positioning, when one hand is on the tube head, and attention is on the receptor and the patient.

Yes, and that is a common use for intraoral views in UK practice. Anterior periapicals show retained deciduous teeth, delayed or ectopic eruption, supernumeraries such as a mesiodens, and the position of developing successors. The findings often decide whether a child is monitored, referred for extraction of a retained primary tooth, or referred to orthodontics. Reduced exposure factors for children should be agreed with your Medical Physics Expert and recorded in your local diagnostic reference levels.

Anterior periapicals are geometrically awkward for reasons unrelated to the machine — a narrow arch, a shallow palate and a receptor sitting far from the tooth all push technique towards elongation. A carried unit lets the operator bring the beam to a patient already settled, but paralleling technique with a beam-aiming holder remains the way to control the geometry.

Interproximal calculus deposits appear as spurs or ledges on bitewing and periapical views, which supports hygienist-led periodontal care and follow-up after a BPE screening. Radiographs show interproximal surfaces well and buccal or lingual deposits poorly, so they supplement rather than replace periodontal probing and charting. Bone-level assessment on the same views is often the more important finding.

Raise this before ordering. UK dental guidance sets minimum focus-to-skin distances for intraoral equipment, and the required figure steps up for sets operating above 60 kV — commonly expressed as 100 mm at 60 kV and below, and 200 mm above 60 kV. This unit offers a 70 kV setting and publishes a 130 mm skin-to-cone figure. Ask the manufacturer to confirm whether that is the focus-to-skin distance or a cone measurement, whether a longer cone is available, and which kilovoltage settings the supplied cone supports. Have your Radiation Protection Adviser resolve it before the unit goes into service.

The pack is a DC 14.8 V 1600 mAh lithium unit, charged from AC 100–240 V with a DC 16.8 V output, so it runs on UK mains directly. The manufacturer does not publish an exposures-per-charge figure. Request it at quotation along with spare pack availability and pricing, particularly if the unit is intended for domiciliary rounds or school and community screening sessions.

The Ionising Radiations Regulations 2017 require employers carrying out dental X-ray work to register with the Health and Safety Executive, appoint a Radiation Protection Adviser, nominate a Radiation Protection Supervisor and complete a radiation risk assessment. The Ionising Radiation (Medical Exposure) Regulations 2017 add the appointment of a Medical Physics Expert, justification and optimisation of each exposure, and documented training for referrers, practitioners and operators. A critical examination is required when the equipment is put into service. These duties sit with the employer.

Dental X-ray equipment is subject to routine quality assurance and periodic radiological testing under IRR17, alongside annual electro-mechanical inspection, with a critical examination required at installation. UK service providers commonly apply an annual radiological testing interval to hand-carried units, and your Radiation Protection Adviser sets the schedule. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months, with battery packs often warranted on a shorter cycle — confirm at quotation.
