Description
X-rays are highly penetrating, ionizing radiation, therefore X-ray machines are used to take pictures of dense tissues such as bones and teeth.
This is because bones absorb the radiation more than the less dense soft tissue. X-rays from a source pass through the body and onto a photographic cassette.
While employing the same advanced technology of dent-x is based on the classic manual selection of exposure times.
xray is compatible with all the digital sensors currently on the market.
Features:
For those that prefer a no-frills unit, biomedicare is the best tradeoff between performance and budget.
Flexibility
To adapt to every installation condition,
dent-X can be configured with a remote X-ray push button that allows you to start the exposure outside the examination room.
The mobile version will give the maximum positioning freedom.

Directions of Uses:-
To reduce radiation exposure, x-ray machines aim the x-rays at only the focus area. When x-rays come into contact with our body tissues, they produce an image on a metal film.
Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them.
Parallel Technique:-
The film is placed parallel to the object being radiographed, and the beam positioned perpendicular to both the sensor/plate and the tooth/root.
This technique results in the most accurate image but is only useful for the caudal mandibular cheek teeth because:
Dogs and cats do not have an arched palate and, therefore, the maxillary teeth cannot be imaged with this technique
The mandibular symphysis interferes with the placement of the sensor/plate parallel to the tooth roots of the mandibular canines and incisors as well as the rostral mandibular premolars.
Bisecting Angle Technique
This technique is based on the theory of equilateral triangles and creates an image that accurately represents the tooth and roots.
The sensor/plate is placed as parallel as possible to the tooth roots.
The angle between the tooth root and sensor/plate is measured or estimated.
Then the angle is cut in half (bisected) and the beam placed perpendicular to this bisecting line.
If the angle between the sensor/plate and the beam is incorrect, the radiographic image will be distorted because the beam will create an image that is longer or shorter than the object imaged.
When the angle of the beam to the sensor/plate is:
Too small, the object will appear longer on the image than its actual length, known as elongation
Too great, the object will appear shorter on the image than its actual length, known as foreshortening.
The bisecting angle technique is the most commonly used technique in veterinary patients because it is the most scientifically correct way to take veterinary dental images and provides the most accurate representation of the root. However, since it is time-consuming, a modified, or “simplified” technique has been developed.
