The Visionstar SJD-341 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.

Surgical dentistry gives intraoral views a defined and useful role, and it is worth being precise about what that role is. A periapical or bitewing shows the distal surface of the second molar, where caries or external resorption caused by an adjacent impacted third molar is a frequent and clinically decisive finding. It shows a partially erupted tooth and the bone around it in pericoronitis. It shows socket healing, retained root fragments and post-operative status after a surgical removal. Those are questions an intraoral projection answers well.

Full assessment of an impacted third molar is a different question. Its position, angulation, root morphology and relationship to the inferior alveolar canal are read from a panoramic radiograph as standard, with small-volume sectional imaging where the canal relationship is the deciding factor. NICE guidance on wisdom tooth extraction directs removal towards teeth with associated pathology rather than routine prophylactic removal, so the radiographic question is usually whether pathology is present — and that is frequently answered on the second molar.

The control face is a 3.5-inch touch panel, presenting settings and machine state on one continuous surface. Published dimensions are 145 × 145 × 140 mm at 1.7 kg.

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-341 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-341 is configured for that daily volume. It supports bitewing caries detection, periapical assessment of pathology, endodontic length verification, alveolar bone-level review and root morphology assessment ahead of extraction.

Oral surgery gives these projections a defined role. The distal surface of the second molar adjacent to an impacted third molar is the territory that matters most — caries or external resorption there is common and frequently the pathology that justifies removal. NICE guidance on wisdom tooth extraction directs treatment towards teeth with associated pathology rather than routine prophylactic removal, so establishing whether pathology is present is usually the radiographic question, and it is often answered on the neighbouring tooth rather than on the impacted one.

Assessing the impacted tooth itself is a different task. Position, angulation, root morphology and the relationship to the inferior alveolar canal are read from a panoramic radiograph as standard, with small-volume sectional imaging where the canal relationship decides the surgical approach.

Post-operative work is a strong intraoral fit. Socket healing, retained root fragments and any concern localised to a single site read well on a periapical, and a carried unit suits a patient who has just had surgery.

Mandibular views carry an interpretive trap worth naming in training: the mental foramen can appear as a well-defined radiolucency near the lower premolar apices and be mistaken for periapical pathology. A second view at a shifted horizontal angulation separates them, and pulp testing settles it.

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

Aimed at the finding that decides the case

Distal caries and external resorption on the second molar are what commonly justify removing an impacted third molar, and they are exactly what a well-angulated intraoral view shows.

Strong for post-operative review

Socket healing, retained fragments and site-specific concerns are intraoral questions, and a carried unit reaches a patient who has just had surgery and would rather stay put.

One continuous control face

A touch panel presents settings and machine state on a single uninterrupted surface, cleaned in one pass as part of the between-patient routine.

Focus chosen for fine findings

Tube focus at 0.4 mm or 0.8 mm is specified at order. Early distal caries and fine retained root fragments reward geometric sharpness, so the choice is worth making deliberately with your Medical Physics Expert.

An exposure envelope that spans the view set

Two kilovoltage settings and four milliamp steps let a protocol reach from paediatric anterior views up to molar bitewings on a large adult, with values agreed by your MPE and recorded as local diagnostic reference levels.

Sized for the drawer and the case

A 145 × 145 × 140 mm body stows in a lockable drawer between sessions and packs squarely for transport, helping discharge the physical security duty IRR17 places on the employer.

Carried by one clinician

At 1.7 kg the unit sits comfortably within single-person handling for a full list, a surgical session or a community round.

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-341 across the United Kingdom, including requesting the manufacturer's panel type, focus-to-skin, cone and filtration documentation.

3.5-inch touch panel

A touch-operated screen forms the control face, presenting settings and machine state on one continuous surface.

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.

145 × 145 × 140 mm body

Published dimensions give a near-square body, suited to lockable drawer storage and to packing squarely in a transport case.

Continuous cleanable control face

The panel presents an uninterrupted surface for between-patient wipe-down; confirm agent compatibility with the manufacturer before selecting a disinfectant.

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

An integrated strap across the housing supports single-hand carrying and steadier beam alignment while the exposure is taken.

1.7 kg published weight

The figure that determines whether one clinician can realistically carry the unit through a surgical session or a community round.

FAQ

Frequently Asked Questions

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

Less about the tooth itself than about its consequences, and the consequences are often what matter. The distal surface of the adjacent second molar is the key territory — caries or external resorption there is a common finding and frequently the pathology that justifies removal. Bone levels distal to the second molar, and the state of a partially erupted crown and its surrounding tissue in pericoronitis, also read well. Treat the projection as answering "is there pathology?" rather than "where exactly does this tooth lie?".

No. Position, angulation, root number and morphology, and the relationship to the inferior alveolar canal are assessed on a panoramic radiograph as standard practice, and where the canal relationship is the deciding factor, small-volume sectional imaging is the appropriate request. Each exposure is justified individually under IR(ME)R 2017, so the projection should follow the question. An intraoral view has a real place in the pathway, but not that one.

A good deal. Socket healing, retained root fragments, the status of an adjacent restoration disturbed during access, and any post-operative concern localised to one site are all intraoral questions. Post-operative films are also where a carried unit earns its place, since a patient who has just had a surgical removal is often more comfortable staying where they are.

One worth naming. The mental foramen sits near the apices of the lower premolars and can appear as a well-defined radiolucency superimposed on or adjacent to a root apex, which is readily mistaken for periapical pathology. A second view at a shifted horizontal angulation usually separates them, since the foramen moves relative to the apex while true periapical change does not. Correlate with pulp testing rather than reading the film alone.

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.

Focus is specified at order as 0.4 mm or 0.8 mm. Focus size governs geometric unsharpness at the receptor, and early distal caries on a second molar or a fine retained root fragment are exactly the findings a sharper geometry helps resolve. Discuss the choice with your Medical Physics Expert alongside your working distance and receptor type, and confirm it in writing on the order.

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, and a backlit touch panel carries its own standby draw, so ask directly. Request it in the quotation along with spare pack availability and pricing.

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.

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 and screen assemblies sometimes covered separately — confirm at quotation.
