The patient is seated upright in the dental chair and should remove any removable dental appliances glasses or jewelry that could interfere with the X-ray beam. To take a periapical exposure the hygienist or x-ray technician places a small photosensitive imaging plate coated with phosphorus into a sterile wrapper and inserts it into the patients mouth just like a conventional X-ray film card.

By using a film sensor holder with still.

. Occlusal X-rays are larger and show full tooth development and placement. The film is placed parallel to the long axis of the tooth to be radiographed and the central beam of X-ray is directed at right angle to the film and the teeth. Fitzgerald called as paralleling or long cone technique.

Different techniques and instruments are used to drain and decompress large periapical lesions ranging from placing a stainless steel tube into the root canal exhibiting persistent apical exudation 202 204 which is non-surgical decompression to placing polyvinyl or polyethylene tubes through the alveolar mucosa covering the apical lesion which is surgical. The image receptor is placed in a holder and positioned in the mouth parallel to the long axis of the tooth under. What are periapical radiographs used for.

The extraoral periapical radiographic technique was performed for both maxillary and mandibular teeth using Newman and Friedman technique2. The paralleling technique results in good quality x-rays with a minimum of distortion and is the most reliable technique for taking periapical x-rays. Intraoral periapical radiographs can be produced using two different techniques.

A long cone is used to take x-rays with paralleling exposure techniques. The X-ray is taken and the exposed plate is then loaded into a scanner or processor which reads the image. By using a filmsensor holder with fixed image receptor and.

Periapical X-rays. Each X-ray reveals the entire arch of teeth in either the upper or lower jaw. Periapical X-rays are used to detect any abnormalities of the root structure and surrounding bone structure.

Ensure they are seated high enough so it is easy to see the occlusal. Inclusion criteria included periapical X-ray images of permanents teeth and patients aged 14 years old with good sharpness. The bisecting-the-angle technique and the more commonly used long cone paralleling technique.

Periapical film is held parallel to the long axis of the tooth using film-holding instruments. Since the slope and curvature of the dental arches and the alveolar processes will not permit the film to be held close to the teeth. These patients may include adults with low palatal vaults and children.

Occlusal X-rays show full tooth development and placement 9. Both techniques have advantages and disadvantages. Demonstration on how to take periapical x-ray using bisecting angle technique.

Exclusion criteria were periapical X-ray images of tooth germs or images which have distortion effects. The Long Cone Paralleling Technique. The X-ray tubehead is then aimed at right angles vertically and horizontally to both the tooth and the image.

Disadvantages to the bisecting technique. Extraoral radiograph Panoramic X-ray Tomograms Cephalometric projections Sialography Computed tomography 10. Paralleling Technique for Periapical X-rays The paralleling technique results in good quality x-rays with a minimum of distortion and is the most reliable technique for taking periapical x-rays.

Bisecting angle and paralleling. Parallel technique The image receptor is placed in a holder and placed in the mouth parallel to the longitudinal axis of the tooth under. With this technique the film is placed parallel to the long axis of a tooth allowing the X-ray to be focused perpendicular to the long axis of the tooth.

The bisecting technique may have to be used for patients unable to accommodate the film positioningdevice used in the paralleling technique. The film is placed parallel to the long axis of the tooth in question and the central x-ray beam should be directed perpendicular to the long axis of the tooth. The X-ray head is directed at right angles vertically and horizontally of both the tooth and the image receptor.

Single periapical radiographs are often made of individual teeth or groups of teeth to obtain information for treatment or diagnosis of localized diseases or abnormalities. The central ray is directed to pass at a perpendicular angle to both the tooth and the film. Periapical views are used to record the crowns roots and surrounding bone.

There are two types of techniques used for periapical radiographs. Periapical X-rays are used to detect any abnormalities of the root structure and surrounding bone structure. The patient was positioned upright with hisher mouth was opened as wide as possible to allow the X-ray beam to pass to the sensor unobstructed from the opposite side of the mouth.

The bisecting short-cone and paralleling long-cone techniques are two of the most commonly used techniques. Periapical film is held parallel to the long axis of the tooth using film-holding instruments. For this purpose a special technique of periapical radiography was developed by Gordon M.

Periapical images have been collected using the FONA X70 Intraoral X-rays machine and PSPIX Imaging Plates. Most frequently used radiography is for the periapical which is performed by the bisecting Thus when considering the execution of the radiographic technique and the possibility of errors that occur during the exposure of X-ray image XR receptors it is important to identify those that occur more frequently.
