One of the direct digital radiographic techniques used in dentistry is radio visiography (RVG). This system is based on digital image capture with a charged coupled device (CCD) capable of image enhancement using up to 256 shades of gray. RVG was first commercially used in the United Kingdom in 1989; since then it has undergone several changes.

To compare the accuracy of radiovisiography (RVG), Root ZX mini Apex locator, and Endo radar's inbuilt Apex Locator during working length determination determination in primary teeth with the actual/direct canal length.

The RVG 142 produces images that can be optimized, thanks to pre-programmed anatomic modes for endo and perio. You can use the filters to increase/decrease image contrast and improve your diagnostic capabilities, as well as the sharpness filter to enhance clinical details.

Three specialized pre-programmed modes—PERIO, ENDO, and DENTINO-ENAMEL JUNCTION—designed to optimize image contrast for enhanced diagnostic accuracy. True HD resolution with 16 lp/mm image quality, ensuring clear, high-definition images.

Fortunately, the RVG 5200 features three preprogrammed anatomic enhancement filters—perio-, endo- and dentinenamel junction—that optimize image contrast according to your needs for faster, more accurate diagnoses. And the system’s easy-to-use sharpness slider bar allows you to customize image appearance to find your ideal look and feel.

2022年11月29日 · Use of RVG has many advantages compared to using a x ray film like: Minimised radiation – RVG can reduce up to 80% of exposure compared to normal x ray films. Faster results – Time is precious for patients as well as …

A size-2 CCD sensor (RVG UI, Trex-Trophy Radiology Inc) was used as the digital receptor in this study. The RVG system provides 6 different modes for image acquisition: 2 levels of spatial resolution for each of 3 diagnostic modes. The high-resolution mode provides large image files of 1840 (width) × 1360 (height) pixels.

Adapt-High Sharp Endo (Fi) Enhances contrast at the canals and roots. Adapt-High Sharp DEJ (Fi) Optimizes contrast at crowns, amelo-dentinal junctions, and roots. Adapt-High Sharp Pro. This family is an optimization of the 'Higher Sharpness' preference available for RVG 6100. It reduces artifacts around radio-opaque materials.

Endo —Optimizes contrast values to display canals and roots. Dentin-to-enamel junction —Strongly accentuates contrast values in the more radio-opaque tissues at the crown, the amelo-dentinal junction, and the roots.
