Radiovisiography – One can come across a customary scenario at a Dental Clinic—a patient approaches a clinic, writhing in toothache, with a gloomy face after spending a painful night. After pretty long time of wait in reception room, eventually gets access to the doctor, who after examining the patient, establishes a provisional diagnosis of his or her condition and announces-need for a X-ray; Patient agrees; X-ray or X-rays taken.
But, not all the clinics provide the report of X-rays instantly as obtaining the X-ray report means a trip down the hail to the developing room, a few minutes of developing, processing and drying. In case of failed X-ray image, again the entire procedure has to be repeated. Needless to mention, the patient is provided the next appointment, only to have more prolonged management, further adding to his or her woes.
This familiar scenario has become a memory of past with the invention of Digital Radiographic technology and the electronic readout devices. The current advances in the field of Dentistry are the testimony that the Digital Imaging System is fast replacing and surpassed the traditional X-ray system with the new, state of the art Dental Digital radiography Techniques.
With the advent of this new technology like radiovisiography, instead of the time consuming and cumbersome procedures of obtaining, developing and processing of X-ray films; dentist and patient can relax and watch the images of teeth and gums right in front on a computer monitor within seconds after the device (Electronic Sensor) is inserted in to the patient’s mouth.
Various computer based imaging systems are available today to get the Digital Dental Images by both the direct and indirect ways. In the direct method, a radiovisiography is used whereas in the indirect method, imaging plates of various sizes are used in the place of X-ray films. Radiovisiography is a computerized radiographic technique in which an electronic sensor is utilized in lieu of conventional X-ray film. Thus, obtained images are transformed in to its digital form and can be viewed on the computer monitor. In this technique, electronic sensor is sensitive to X-rays.
Hence, when exposed to radiation, radiovisiography captures the image of an object and sends the electronic message through the fibreoptic cable to the hardware of CPU of computer, which in turn works on it and converts the message obtained in to the digital image with the help of software.
Digital images so received can be viewed on the computer monitor, which can be worked on and stored in the computer for the permanent record. The main important facet of radiovisiography is the avoidance of X-rays, which are otherwise mandatory to arrive at a proper and final diagnosis and appropriate management planning in any case.
Apart from conserving time of the doctor, his assistant and the patient by obtaining the quickest scanned images, the other advantages of radiovisiography are too many to mention a few. The prime one among all of them is approximately 90% reduction in X-ray dosage, the doctor and patient used to receive in the conventional X-ray technique.
Here they are exposed to only 1/10th of the X-ray dosage delivered in normal conventional X-ray technique. Hence, due to this advantage, the radiovisiography is relatively safe to the females during pregnancy and children especially, where the high radiation dose is very harmful.
Moreover the scanned images are of high resolution giving sharper, faster, clearer and accurate images than X-ray film images. The digital images can immediately be stored in the computer memory for the future and permanent patient record. Thousands of such images can be stored this way and can be instantly recalled at any date in future.
They can not only be easily retrieved but also can be combined and manipulated to supply more information. Hence, all the problems associated with X-ray films like storage and missing of X-rays can be eliminated.
There is a definite improvement in diagnostic performance of radiovisiography over the conventional radiography, in detecting hidden and not so easily seen carious lesions, apical pathology and pathologies of gums. Being eco friendly in nature, the radiovisiography saves chemical waste associated with X-ray films and provides a great help in maintaining office hygiene as well.
Intra-oral camera is again a digital device and an integral part of the Innovative Digital Dentistry which has got built-in image capture facilities and provides the patient the finest imaging Intra-oral photography. This is also an excellent. Patient motivation and education device. Patient can view his or her dental condition while relaxing in a dental chair and also view the justification of required urgent or suggested treatment plan (by dentist) and very importantly the improvement or progress postoperatively.
