Dental x-ray Machine

Dental X-rays are pictures of the teeth, bones, and soft tissues around them to help find problems with the teeth, mouth, and jaw. X-ray pictures can show cavities, hidden dental structures (such as wisdom teeth), and bone loss that cannot be seen during a visual examination. Dental X-rays may also be done as follow-up after dental treatments.

The following types of dental X-rays are commonly used. The X-ray machine use small amounts of radiation.

Bitewing X-rays show the upper and lower back teeth and how the teeth touch each other in a single view. These X-rays are used to check for decay between the teeth and to show how well the upper and lower teeth line up. They also show bone loss when severe gum disease or a dental infection is present.

Periapical X-rays show the entire tooth, from the exposed crown to the end of the root and the bones that support the tooth. These X-rays are used to find dental problems below the gum line or in the jaw, such as impacted teeth, abscesses, cysts, tumors, and bone changes linked to some diseases.

Occlusal X-rays show the roof or floor of the mouth and are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft in the roof of the mouth (cleft palate), cysts, abscesses, or growths. Occlusal X-rays may also be used to find a foreign object.

Panoramic X-rays show a broad view of the jaws, teeth, sinuses, nasal area, and temporomandibular (jaw) joints. These X-rays do not find cavities. These X-rays do show problems such as impacted teeth, bone abnormalities, cysts, solid growths (tumors), infections, and fractures.

Digital X-ray is a new method being used in some dental offices. A small sensor unit sends pictures to a computer to be recorded and saved.

A full-mouth series of periapical X-rays (about 14 to 21 X-ray films) are most often done during a person's first visit to the dentist. Bitewing X-rays are used during checkups to look for tooth decay. Panoramic X-rays may be used occasionally. Dental X-rays are scheduled when you need them based on your age, risk for disease, and signs of disease.
Many of us have been to the dentist recently enough to remember how uncomfortable it is to get dental x-rays taken. Biting down on a sharp piece of x-ray film, while the dentist triggered the x-ray machine from behind a lead shield, used to be an unavoidable part of dental care. However, new technologies have developed which can eliminate this type of discomfort, as well as providing better-quality images. Dental digital x-rays are a product of these technological advances. With these, the x-ray film is replaced with an electronic sensor which emits a small amount of x-rays into the part of the mouth it is pointed at, and relays information back to a computer screen, where both dentist and patient can clearly see how the patient's teeth are doing.

There are numerous advantages of dental digital x-rays, as opposed to traditional dental x-rays. First of all, anything that reduces the discomfort experienced in the dental chair is welcomed, and these newer x-rays do just that. Also, there is no need to wait for the x-ray film to be developed before it can be viewed, meaning the checkup as a whole takes less time. The image brought up on the computer screen is also clearer, in part because the sensor used to make dental digital x-rays is much more sensitive than x-ray film. Because it is more sensitive, the patient's x-ray exposure can also be dramatically reduced.

Many dental patients have said that with dental digital x-rays, it is easier to understand the course of treatment, if any, which the dentist wishes to take. This is because they are able to see the image enlarged on a screen in front of them, rather than trying to interpret a small piece of film held up to a light box. The cost of getting dental digital x-rays taken is usually comparable to that of traditional x-rays, so many dental insurance companies cover their cost.

One of the most significant features of dental digital x-rays is that, with the proper additional software, dentists can use a technique known as subtractive radiography. This means that new x-ray images can be compared with older ones from the same patient. This comparison is performed digitally, by the computer, meaning that it will sometimes catch differences that would escape detection in a visual comparison. The patient is the one who benefits most from this, because potential problems can often be seen and caught earlier by this method than they would have been otherwise.

X-Ray Machine High Frequency

Perlong Medical Equipment Co. Ltd, has many of medical equipment product. Perlong Group, headquartered in Beijing. The Perlong company was considered as the largest medical equipment manufacturer and supplier in China include Clinical Laboratory Equipment, Surgical Equipment, X-ray Machine, and Medical Consumables.

Especially for the X-Ray machine, they has released High Frequency mobile X-Ray Machine. There are two mobile X-ray machine which known as great performance, X-Ray machine PLX101D and X-Ray machine PLX112.


X-Ray machine PLX101D
These is high frequency mobile X-ray equipment (100mA) with power output : 5.0KW. The PLX101D futures by a system Wire/Wireless control to operation method. The X-Ray machine's tube using Fixed anode. When you purchase this X-Ray machine you will get an extra battery.

X-Ray machine PLX112
The X-Ray machine PLX112 was known as high frequency Mobile Surgical X-ray equipment with a high-quality knockdown X-ray generator to reduce radiation, For the medical team it's become importance reason to choose this product.

The X-Ray machine PLX112 using automatic fluoroscopy system, by setting the Tube to the Voltage:40kV～110kV. Special performance of this x-ray machine is future by High Frequency Fixed anode X-ray tube with 2 foci:Large focus: 1.5mm, small focus: 0.6mm, Inverter Frequency: 40KHz and Thermal capacity: 30KJ (40HU).

Dental x-ray
Dental radiographs, commonly referred to as X-ray films, or informally, X-rays, are pictures of the teeth, bones, and surrounding soft tissues to screen for and help identify problems with the teeth, mouth, and jaw. X-ray pictures taken by X-ray machine can show cavities, cancerous or benign masses, hidden dental structures (such as wisdom teeth), and bone loss that cannot be seen during a visual examination. Dental X-rays may also be done as follow-up after dental treatments.


A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. Teeth appear lighter because less radiation penetrates them to reach the film. Dental caries, tooth decay, infections and other changes in the bone density, and the periodontal ligament, appear darker because X-rays readily penetrate these less dense structures. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the density of the material


The dosage of X-ray radiation received by a dental patient is typically small, equivalent to a few days' worth of background radiation environmental radiation exposure, or similar to the dose received during a cross-country airplane flight. Incidental exposure is further reduced by the use of a lead shield, lead apron, sometimes with a lead thyroid collar. Technician exposure is reduced by stepping out of the room, or behind adequate shielding material, when the X-ray source is activated.
