Newman and Friedman (), in this journal, have recently proposed an effective approach for obtaining periapical radiographs, an extraoral radiographic technique, which can be used in the treatment of a wide spectrum of patients, such as those with a developmentally disabled, exaggerated gag reflex, those of a young age, and patients with dental phobia Dental x-rays are used to diagnose diseases affecting the teeth and the bones since the inside of these structures is not seen when dentists look in your mouth. They provide important information to help plan the appropriate dental treatment. They may be used to identify: Number, size, and position of the teeth 3.  Extraoral radiograph is defined as: Examination made of the head and facial region using films located outside the mouth.  They allow the dentist to view large areas of the jaws and skull on a single radiograph not covered by intraoral films 4

This view is used to evaluate the interproximal decay and bone loss of the posterior teeth. Bitewing X-Rays are often preferred by dentists, because they can accurately depict the bone levels more than other views of the mouth. The Periapical View. The periapical view is a dental radiograph that is taken of both anterior and posterior teeth There are a few kinds of dental x-rays, with each one recording different views of the mouth. One type is called extraoral x-rays that are used when the dentist suspects problems in areas outside the teeth and gums, like the jaw. The second and most common type are intraoral x-rays, which include the following Placing the photographic film or sensor outside the mouth, on the opposite side of the head from the X-ray source, produces an extra-oral radiographic view. A lateral cephalogram is used to evaluate dentofacial proportions and clarify the anatomic basis for a malocclusion, and an antero-posterior radiograph provides a face-forward view

They are also used for orthodontics, endodontics / root canals, and other oral surgeries. And they can also be used for implant patients as the dentist can use the cross-sectional template to visualize slice-by-slice distances for the most precise measurements during implant planning Dental x-rays are used to make quick and painless images of your teeth and jaws. X-rays are invisible beams of energy, a form of radiation. The images are displayed on film or on the computer monitor (digital imaging) after the x-rays pass through an area of the body and are absorbed differently depending on the density of the structures Where permitted by law, auxiliary dental personnel can perform intraoral and extraoral imaging. 103 Personnel certified to take dental radiographs should receive appropriate education.

The extraoral radiography using the extraoral films finds its use in imaging the skull, temporomandibular joint along with the jaw bones. The use of intensifying screens along with the extraoral films helps reducing the patient exposure. The x-rays help to image the internal structures on the film and allowing the dentist to see the hidden issues Indications of different types of extraoral radiograph Part 2. IV.

Particular emphasis should be placed on whether a patient reports a strong gag-reflex or has previously struggled with intraoral radiographs Objective: The standard imaging techniques used in dentistry consist of two-dimensional radiographic techniques like intraoral periapical (PA) radiographs, bitewings or extraoral panoramic X-rays. Three-dimensional methods, such as cone beam computed tomography (CBCT), are not standard procedures. In several fields of dentistry, such as oral surgery or implantology, dental magnetic resonance. Introduction. Shortly following the discovery of the X-rays by Wilhelm Conrad Röentgen on 8 November 1895 the first dental radiographs were produced which were somewhat similar to bitewing (BW) radiographs but lacking in diagnostic quality. 1 From these beginnings, intraoral BWs have become the primary diagnostic tool used for the detection of proximal surface caries which are not visible.

A lateral cephalometric radiograph (LCR) is a standardised, reproducible radiograph used primarily for orthodontic diagnosis and treatment planning. It is taken from a distance of 1.5m with the head at a right angle to the X-ray beam at a distance of 30cm, (although this has been found to vary slightly) Bay Dental Health, Bay Shore, NY. The Planmeca Extraoral Bitewing technique has become an essential part of our daily workflow. Our patients benefit from lower radiation and greater comfort. Clinically we benefit by seeing more and diagnosing our patients' problems earlier, avoiding unnecessary cost and complications Extraoral X-ray Imaging Summary: Extraoral X-rays show teeth, but their main focus is the jaw and skull. These X-rays do not provide the detail found with intraoral X-rays and therefore are not.
