Dental RVG Sensors

Dental RVG Sensors for Digital Intraoral X-Rays

An RVG sensor (RadioVisioGraphy sensor) is a digital intraoral X-ray sensor that replaces dental film. It is placed in the patient's mouth like a film packet, exposed with an intraoral X-ray unit, and sends the image to a computer within seconds. RVG sensors capture periapical (IOPA) and bitewing radiographs, usually at a lower exposure than conventional film, and the images can be enhanced, measured, stored and shared digitally.

This range includes RVG sensors from Vatech, Carestream, Dentsply, Acteon, Woodpecker, Eighteeth, Unicorn Denmart (Xpect Vision) and Apple Dental, from entry-level to premium systems, for dental clinics, multi-chair practices, dental colleges and hospitals. For a full explanation of RVG technology and its history, read our guide to RVG in dentistry.

How an RVG Sensor Works

Most modern RVG sensors use a CMOS detector. A scintillator layer converts X-rays into light, which the CMOS chip turns into a digital image; older sensors used CCD chips. Some newer sensors use direct-conversion or photon-counting detectors. The sensor connects to a computer, usually by USB or wirelessly, and the imaging software displays the image almost immediately. Phosphor plate (PSP) systems are an alternative that uses reusable plates scanned after exposure.

RVG Sensor Sizes

Many practices start with one size 1.5 or size 2 sensor and add a smaller sensor later. The Vatech EZ Sensor Classic, for example, is a CMOS sensor in size 1.5 (also available in sizes 1 and 2) with a 4.8 mm slim, IP68-sealed aluminium body, indicated for bitewings and periapicals.

Wired vs Wireless RVG Sensors

Wired (USB) sensors connect directly to the computer, need no charging and are the most common choice. The cable is the part most exposed to wear, so cable strength and strain relief are worth checking. Wireless sensors transmit images without a cable, which makes positioning easier and avoids cable damage, but they cost more, need charging or batteries, and depend on a stable connection. Image quality is determined mainly by the detector, not by whether the sensor is wired or wireless.

What to Compare When Buying an RVG Sensor

• Image quality: resolution and dynamic range (bit depth), and the clarity of fine detail such as root canals and early caries.
• Size and thickness: a slimmer sensor with rounded corners is more comfortable for patients.
• Durability: sealed (IP-rated) housing, cable strength and strain relief, and resistance to bites and drops.
• Software: ease of use, image tools, DICOM export and compatibility with your practice management software.
• Computer compatibility: most RVG software runs on Windows; check the supported versions and USB requirements.
• X-ray unit compatibility: RVG sensors work with standard intraoral X-ray units; a DC unit gives more consistent low-dose exposures.
• Warranty and service: sensor and cable warranty, and access to service and replacement in India.

Value models such as the Woodpecker i-Sensor suit new practices, while premium systems offer more advanced software and imaging.

Which RVG Sensor Is Best for Your Practice?

There is no single best RVG sensor; the right choice depends on your case mix, budget and workflow.

• New practices and tight budgets: an entry-level CMOS sensor in size 1.5 with reliable software and a good cable warranty.
• Busy general practices: a mid-range or premium sensor with strong image quality, durable construction and software that integrates with your practice system.
• Endodontics and implant work: a high-resolution sensor with advanced image processing and measurement tools.
• Paediatric practices: a size 0 or size 1 sensor, alongside an adult size.

RVG Sensor Price in India

RVG sensor price depends on the brand, size, technology, software and warranty. As a general guide to the sensors on this page:

• About ₹50,000 to ₹65,000: entry-level and value CMOS sensors.
• About ₹85,000 to ₹1,40,000: mid-range and established brands with advanced software.
• About ₹1,70,000 and above: premium imported systems.

Wireless sensors and larger kits cost more. Prices change with offers and stock, so check the listing above for current prices.

Care, Infection Control and Accessories

• Cover the sensor with a new disposable barrier sleeve for every patient.
• Between patients, wipe the sensor and cable with a disinfectant approved by the manufacturer. Never autoclave, heat-sterilise or immerse an RVG sensor unless the manufacturer specifically allows it.
• Avoid bending, kinking or pulling the cable, and do not let patients bite directly on the sensor.
• Use sensor holders or positioners for consistent, parallel images and fewer retakes. Medikabazaar stocks RVG positioners and sensor holders as well as RVG sleeves.
