How To Choose The Best Dental X Ray Machine For Dentists

Table of Contents

Dental X Ray Machine in the dental clinic is mainly used to assess the teeth’ structure in a bid to ascertain if they are healthy or have any detectable deformities.

A dentist’s practice premise is one of the places where you may find a lot of equipment around for dental procedures. Understandably so due to the complexity of dental procedures that require a vast assortment of equipment for efficiency in tackling the various dental issues that are presented at the dental clinic.

Let us have a more in-depth look at the equipment that is the dental X-Ray kit.

The Dental X-Ray Machine

The dental X-Ray machine works in the same way as the first X-Ray machine where it emits X-Rays, which are electromagnetic rays. One of the most useful types of equipment that you may come across in the dental clinic is the dental X-Ray machine. The dental X-Ray machine can be said to be very significant in such a setting due to its scope of work.

The machine is also used for plotting purposes when it comes to invasive dental surgery where the dentist wants to know the area for the surgical operation. The X-Ray machine is very significant when it comes to the clinical setting by just looking at the uses it has.

Dental X Ray Machine How It Works

If you are planning or you already own a dental practice clinic, the X-Ray machine is one of the types of equipment that you need to have in your equipment catalog. However, as a professional, you do not just go purchasing equipment without knowing its use and how it works.


You already have an idea of how the Dental X Ray Machine works where it helps in checking the bone structure of the oral cavity. The main question at this juncture is how the dental X-Ray machine works.

To know how the X-Ray machine works, you have to go in-depth to its basis of functionality, which is the X-Ray. A glimpse into the X-Rays will provide you with a stepping stone in getting the concept of the working of the dentists’ X-Ray machine.

  • The X-Ray

The X-Ray is electromagnetic radiation with a wavelength range of 0.01 to 10 nanometers and was discovered by scientists in the last quarter of the 1800s. The X-Rays can pass through a variety of objects and give out the image on a film of the outline of the object. This is the central concept when it comes to highlighting bones and teeth in the oral cavity.

Having known what the X-Rays are, we now get back to the dental care X-Ray machine. Here, the X-Ray machine through its X-Ray generator emits a beam of concentrated electrons. The naked eye can not see the X-Ray beams due to their wavelength.

So when the beams come into contact with human tissue, it can produce an image of the outline of the object on a metal film, the same way as in photography. Bones are known to absorb high-energy rays that are why the impression on the metal films mostly depicts the structure and outline of bones.

Soft tissue such as skin and other organs do not have high absorbing power; hence, most of the time, their structure is not seen. However, with some tweaks on the X-Ray generator, where the ability of the rays is set to different wavelengths, soft tissue can be seen.

  • In The Oral Cavity

When it comes to the oral cavity, where a dentist’s majority of work lies, the X-Rays from the dental X-Ray machine are absorbed by the teeth and jawbones. The soft tissue such as the gums and tongue are most of the time not featured due to the earlier stated low absorbency rate of such tissues.

The teeth and surrounding bones that have absorbed the rays appear lighter on the X-Ray film that is usually produced. In case of decay, missing teeth or broken bones, it will be shown by darkened areas on the entire oral cavity depiction on the X-Ray film.

  • What Do Dental X-Rays Show?

As earlier indicated, the primary purpose of the dental X-Ray machine is to help in checking the state of the bones and teeth. There are many things that the X-Ray impression on the X-Ray film can help to show, as highlighted below.

  • Checking for cavities on the teeth where it will show as a dark spot.
  • In assessing for tumors in the gum or entire oral region.
  • To check for abscess or bleeding in the gum or mouth. Bleeding or abscess is indicated by a bulging dark spot on the X-Ray film.
  • The dental X-Ray can help in checking for abnormal teeth growth in the gums, which is helpful when coming up with the right corrective measures.
  • In situations where the tongue or gum has been poked or pieced, the X-Ray can help in situating the object used to cause the injury.
  • In some situations where a client has dental implants, the X-Rays help to ascertain the type of material used for the implants. Some elements appear dark while others appear light, which is helpful in identification.

These are some of the issues that a dental X-Ray machine can solve. With an idea of what is precisely ailing the oral cavity, a dentist can come up with a proper measure to treat the condition.

  • What Is The Dental X-Ray Film?

The dental X-Ray film is like the central part and also the conclusion to the dental X-Ray exam. The film is where the outline in the structure of the oral cavity is depicted. The film looks like a negative film only more comprehensive and uses light coloration for the structure to be seen well.

In the film, the dentist can look at the focused area of the mouth cavity be it the bones or soft tissue to single out issues affecting it. The X-Ray film is also used for recording and referral purposes in case of any arising medical problem with the client.

Dental X-Ray Machine Types

Dental X-Ray Machine Types

When it comes to dental X-Ray machine types, there are two types that you can pick from depending on the location of the X-Ray films. The two models are the intraoral X-Ray where the X-Ray film is inside the mouth and the extraoral X-Ray where the film is outside the mouth.

Let us view the two types of oral X-Rays in-depth to know more about them.

The term bitewing is used as the patient is supposed to bite on the films put on either side of the mouth as the X-Ray beam is generated.

The impression appears on the film showing the tooth from its crown down to the level of the supporting bone. Apart from checking on cavities, bitewing X-Rays are also used to determine the size of implants such as crowns or bridges in a bid to strengthen the teeth.

  • Periapical X-Rays

Periapical X-Rays are intraoral X-Rays that are used to check on the whole structure of individual teeth from the crown down beyond the root to the point of attachment to the jawbone. The periapical X-Ray is used in assessing the teeth mostly about its origin and can help in the detection of diseases affecting the source.

It is also reliable when it comes to assessing the jawbone and the gum and see if they have any defects. The periapical X-Ray both captures one tooth or two at once and can check for tumors at the gum level.

For this X-Ray to be taken, a film is placed near the mouth of the patient using a metal rod with a ring. The patient needs to bite on the device with the film firmly as the X-Ray beams are generated.

  • Occlusal X-Rays

Occlusal X-rays are used mostly in kids to assess the growth of teeth. The occlusal X-Rays mainly capture the roof and floor of the mouth and show the underlying emerging teeth in children who are in the teeth shedding age.

The tomogram X-Ray machine for dentists is used in capturing a specified layer of the mouth while blurring out other areas that are not significant. The tomogram X-Ray is used in a situation where specific organs may block a wanted view; hence, the organs are blurred out for a perfect view of the selected area.

The tomogram X-Ray machine is vital in checking out for tumors in the oral cavity and determining whether the tumors are benign or malign.

  • Cone Beam Computed Tomography X-Ray

The cone-beam computed X-Ray machine is used in coming up with three-dimensional images as a representation of a selected structure in the mouth. The cone beam X-Ray is vital in assessing the structure if the jawbone or a single tooth. It is crucial when it comes to designing teeth crowns or bridges and fixing other implants on the tooth.
