We are witnessing the new advancement and technology in digital imaging systems for the last 10 years. Indian dentistry, especially in digital means is massively expanding. Those were the days when a dental x-ray system was time-consuming, environmentally not safe due to chemical uses in film development. But nowadays the transformation in the radiology division has made the diagnosis and customization for the dental practitioner more easy and precise.
Problem With A Intraoral Digital Sensor(RVG):
Although RVG is 1st choice of a dental practitioner for digital imaging for the dental practice, it has a lot of disadvantages.
- RVG give quick result in terms of image constructions on the screen, but on another hand, it provides more discomfort to the patients and more radiation exposure to the doctor as he usually put his finger inside the patient mouth to fix the RVG for radiation exposure.
- The problem of wire cutting or bending at the junction creates more financial risk to doctors when using RVG.
- More incidents happen when the RVG sensor falls from the hand or a patient unintentionally bites the sensor and it gets damaged.
- In restricted mouth opening and child patients, it is more difficult to put rigid RVG in the proper place to get the right and correct images.
- In the majority of the cases in impaction especially distoangular and verticle, RVG can’t be placed correctly and capture the periapical area or root curvature in one image.
- Moreover, patients feel gaging reflux and become more uncooperative during placing RVG.
In the last few years, when dental practitioners noticed and experienced the above-said problems with the Intraoral sensors (RVG), they started looking for new solutions where the PSP System (Photo Stimulated Phosphor Plate and scanner) plays a very important role and great solutions.
Principle: Photostimulated luminescence
Photostimulated luminescence (PSL) is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. Dental X-rays may induce such energy storage. A plate based on this mechanism is called a photostimulable phosphor (PSP) plate. Creating an image requires illuminating the plate twice: the first exposure, to the radiation of interest, “writes” the image, and a later, second illumination (typically by a visible-wavelength laser) “reads” the image.
Structure and Mechanism
On photostimulable phosphor (PSP) plates, the phosphor layer is typically 0.1 to 0.3 mm thick. After the initial exposure by X-ray, excited electrons in the phosphor material remain ‘trapped’ in ‘color centers’ in the crystal lattice until stimulated by the second illumination. PSP plates absorb x-ray radiation and store it as trapped electrons in the crystal structure, forming a latent image. If stimulated with additional light of an appropriate wavelength, the deposited energy can be released.
Benefits of PSP System Over RVG
PSP system has a thin, flexible, and wireless plate that can be easily placed inside the mouth even in the restricted mouth opening. Below are the advantages of PSP over the Rigid Digital Intraoral Sensors:
- PSP system has 100% active area, which means the size of the PSP plate can form the image on its complete area, whereas it is 80-85% on Digital Sensor. For example, if we use the size 1 Digital sensor and Size 1 PSP plate, then the PSP plate will show more teeth and adjacent area (complete coronal-to-apical length and obtain more mesial-distal information) in the final image than to RVG.
- PSP plates are more thin and flexible than RVG rigid sensors. So it is easier to place PSP plates inside the mouth than RVG
- PSP plates are wireless so there is no fear of wire cutting or bending as it is present in RVG
- PSP has various sizes options within a single unit. So it is more economical and cost-effective than RVG.
- The maintenance cost is almost nil in PSP. In case a PSP plate gets damaged, the replacement cost is very minimal, but is in lacs in the case of RVG.
- As the PSP plate is held by the patient finger, so there is less radiation exposure to dental practitioners than RVG
