One can better appreciate the significance of dental X-rays in preserving optimal oral health by becoming familiar with the many kinds of X-rays used in dentistry and their functions. Understanding the various types of dental X-rays for the mouth could help you appreciate their importance for both children’s and adults’ oral health.
X-rays are used by dentists to examine the condition of your teeth, bones, and any fillings, crowns, or implants you might have. However, not every dental x-ray is the same.
Depending on what they’re attempting to view, dentists employ a variety of x-rays. Some of the most prevalent dental x-rays and their applications are listed below:
The most typical kind of dental X-rays are intraoral X-rays. They offer a thorough image of the supporting tissues, bone, and teeth inside the mouth. Intraoral X-rays come in a variety of forms, such as bitewing, periapical, and occlusal X-rays.
To examine one particular area of your mouth, a bitewing x-ray is utilised. During your check-up, your dentist might ask for a single bitewing x-ray or several. Your upper and lower teeth, as well as half of their roots and supporting bone, are all covered by each bitewing. Dentists use bitewing x-rays to find decay, particularly in the spaces between teeth. Additionally, they assist dentists in identifying jawbone alterations brought on by gum disease.
When your dentist takes a regular x-ray, you will be asked to bite down on a piece of plastic that holds the x-ray film against your upper and lower teeth. This is how bitewing x-rays are taken. You will be asked to bite down on a little box that is wrapped in plastic if your dentist uses digital x-rays.
An x-ray that includes the entire tooth is called a periapical one. The root (below the gum line) and the crown (chewing surface) are both visible. Your upper or lower teeth are visible in a little portion on each periapical x-ray. These x-rays are frequently used to look for any unexpected changes in the bone structures surrounding the root.
The periapical x-rays method: A metal rod with a ring attached will be used to position the film close to your mouth. To hold the device in position and provide a clean x-ray image, you must bite down firmly on it.
Full Mouth Survey X-rays
A bitewing and periapical picture combo is among the various images that make up a full mouth survey x-ray. Typically, when you first visit your dentist, complete mouth x-rays are done. These initial pictures serve as a benchmark for the condition of your mouth. However, when your dentist thinks you have a jaw cyst or tumour, full mouth x-rays are frequently performed. Additionally, they are employed for major dental procedures like root canals, extractions, and the management of gum disease.
You will be asked to take bitewing and periapical x-rays in order to obtain a full mouth survey.
Similar to panoramic photographs, panoramic x-rays are utilised to capture images of your whole mouth region. It displays all three tooth positions—fully emerged, emerging, and impacted—in a single picture.
You will be asked to bite down on a “bite blocker” to keep your teeth aligned and get a clear image during the taking of a panoramic x-ray. The equipment then records your mouth by moving an arm in a semicircle around your head.
Occlusal x-rays are used to monitor the growth and positioning of a whole arch or a segment of teeth in the upper or lower jaw. Paediatric dentists primarily utilise them to locate children’s teeth that have not yet poked through the gums.
The procedure for taking occlusal x-rays is quite similar to that of a bitewing x-ray.
The teeth, jaw, and skull are visible on extraoral X-rays, which are obtained outside the mouth. They are used to find problems such tumours, impacted teeth, and jaw problems. Extraoral X-rays come in a variety of forms, such as cone beam computed tomography (CBCT) and panoramic X-rays.
Cone beam computed tomography (CBCT)
A 3D image of the teeth, jaw, and skull is provided by CBCT. It is frequently used to plan oral surgery, orthodontic treatment, and dental implants. CBCT offers a more accurate view of the teeth and jawbone and is more detailed than panoramic X-rays.
Dental X-rays are a crucial component of dental treatment. From cavities to jaw abnormalities, they assist dentists in the diagnosis and treatment of a variety of dental conditions.
