Dental x ray parallel technique
What is the difference between bisecting and paralleling technique?
Disadvantages to the bisecting technique include image distortion, and excess radiation due to increased angulations exposing the eyes and thyroid.
Paralleling technique provides less image distortion, and reduces excess radiation to the patient..

What is the parallel cone technique?
The long-cone paralleling technique is based on the following principles: an increased distance between the radiation source and the film to obtain a bundle of parallel rays; an increased distance (except for the lower molar region) between the tooth and the film to obtain parallelism between the film and the long-axis .
What is the parallel placement technique?
The parallel technique is defined as the parallelism between the object to be studied and the plane of the film while the central axis of the X-ray is perpendicularly adjusted to both planes..
What is the parallel technique?
3.
The parallel technique is defined as the parallelism between the object to be studied and the plane of the film while the central axis of the X-ray is perpendicularly adjusted to both planes.
Unfortunately, it is much easier to get a perpendicular position of the X-ray central axis to the film than to the object..
What is the paralleling technique of placement?
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 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.Jul 10, 2017.
When using the paralleling technique in what direction is the x-ray beam aimed?
The paralleling technique requires (1) that the film be placed parallel to the long axes of the teeth being radiographed and (2) that the x-ray beam be directed at right angles to both the film and long axes of the teeth..
- There are many types of x-rays but they all fall into two categories: intraoral (inside the mouth) or extraoral (outside the mouth), helping your dentist create a full picture of your current, and future oral health.
- 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.Jul 10, 2017
The paralleling technique is the most commonly used technique for exposing periapical and bitewing radiographs because it creates the most accurate representation of a tooth image. It refers to the receptor being positioned parallel to the full length (long axis) of the tooth being radiographed.
The paralleling technique is accomplished by placing the receptor parallel to the long axis of the tooth. After this parallel relationship has been established, the central ray must be directed perpendicular to both the tooth and receptor.
Preparing The Instruments and X-Ray Equipment
It is often easier to prepare the X-ray equipment before the film is carefully situated in the patient’s mouth Reducing The Risk of Errors
Common errors that can affect the quality of the image include failing to remove glasses or jewelry which may mean these objects obscure anatomical Can X-rays be paralleled?
The data suggested that applying the paralleling technique was impossible in 95% of cases
In the cases where application of the paralleling technique was impossible, the incident angle of X-ray increased by 31
6°
How X rays are aligned perpendicular to a tooth?
The central x-ray beam is then aligned perpendicular to the tooth being radiographed
Film holding devices, such as the XCP (extension-cone paralleling) device are explained in this module, along with the 5 basic rules for performing the paralleling technique
The paralleling technique is the most commonly used technique for exposing periapical and bitewing radiographs because it creates the most accurate representation of a tooth image. It refers to the receptor being positioned parallel to the full length (long axis) of the tooth being radiographed.In the paralleling technique, the film is placed in the mouth so that the long axis of the film is parallel with the long axis of the teeth being radiographed. A paralleling instrument with an aiming ring is normally used to orient the film, teeth and ring in a parallel relationship.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 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.
