Which technique is most often used when exposing a periapical image?
Intraoral periapical radiographs can be produced using two different techniques; the bisecting-the-angle technique and the more commonly used long cone paralleling technique.
What are the 2 basic techniques used to expose intraoral film?
The two basic techniques for obtaining periapical x-rays are the paralleling technique and the bisecting (bisection of the angle) technique.
What are the two techniques for exposing radiographs?
There are two types of techniques used for periapical radiographs: bisecting angle, and paralleling.
Is an intraoral technique of exposing periapical images?
An intraoral technique of exposing periapical films in which the film and the teeth create an angle that is bisected by the beam. Radiographs with the proper images and optimum density, contrast, definition, and detail. The term that is used to describe a space between two adjacent surfaces.
Why is bisected angle technique used?
Introduction. This technique is used in areas where the parallel technique is impossible due to poor access, making the angle between tooth and film more than 15 degrees. Using this technique, a true image of the tooth length and width is obtained.
What is 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.
What are radiographic techniques?
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography.
Why is the sequencing of exposure important?
why is an exposure sequence important? If you work without a planned exposure sequence, you are more likely to omit an area or expose the same area twice.
What is the difference between paralleling and bisecting technique?
The paralleling technique, when performed correctly, is superior to the bisecting angle technique because it produces an image with both linear and dimensional accuracy. The bisecting angle technique is accomplished by placing the receptor as close to the tooth as possible.
What is bisecting technique?

What is the difference between bisecting and paralleling technique?
The paralleling technique, when performed correctly, is superior to the bisecting angle technique because it produces an image with both linear and dimensional accuracy. The bisecting angle technique is accomplished by placing the receptor as close to the tooth as possible.
How many techniques are there in radiography?
In industrial radiography there are several imaging methods available, techniques to display the final image, i.e. Film Radiography, Real Time Radiography (RTR), Computed Tomography (CT), Digital Radiography (DR), and Computed Radiography (CR).
What are CT techniques?
The term “computed tomography,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine's computer to generate cross-sectional images, or “slices.” These slices are called …
What is radiographic technique?
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography.
What are the two techniques for obtaining periapical images?
Two types of exposure techniques may be used for intraoral periapical radiography: the paralleling and the bisecting angle technique (Figures 1 and 2). With the paralleling technique, the tooth and the sensor are both kept on a parallel planes.
What is paralleling technique in dental radiography?
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.
What is bitewing technique?
The bitewing radiograph (BW) is an image that depicts the maxillary and mandibular crowns of the teeth, providing a clear image of the interproximal surfaces of the teeth and allowing for detection of interproximal caries.
What are radiology techniques?
These techniques include x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI). These imaging tools let your doctor "see" inside your body to get a "picture" of your bones, organs, muscles, tendons, nerves, and cartilage. This is a way the doctor can determine if there are any abnormalities.
What’s the difference between CT scan and CT scan?
So, CAT and CT scans both mean the same type of diagnostic examination. CAT was used earlier in its history, while CT is the recent up-to-date term for convenience sake. The term CT stands for computed tomography and the term CAT stands for computed axial tomography or computerized axial tomography scan.
What is a fluoroscopy procedure?
During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a monitor so the movement of a body part or of an instrument or contrast agent (“X-ray dye”) through the body can be seen in detail.
What are the 5 imaging techniques?
Learn more about our five most common modalities for our various types of imaging tests: X-ray, CT, MRI, ultrasound, and PET.
What is CT scan technique?
A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body. It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels. CT scans are more detailed than standard X-rays.
Which is worse MRI or CT scan?
CT scans are more widely used than MRIs and are typically less expensive. MRIs, however, are thought to be superior in regards to the detail of the image.
What is interventional and fluoro?
Interventional Fluoroscopy. Page 1. Introduction. Interventional fluoroscopy uses ionizing radiation to guide small instruments such as catheters through blood vessels or other pathways in the body.
What are the types of fluoroscopy?
Types of Fluoroscopy
- Musculoskeletal Fluoroscopy. …
- Barium Swallow. …
- Fluoroscopic Enteroclysis. …
- Fluoroscopic Defecography. …
- Fluoroscopic Small Bowel Follow Through. …
- Fluoroscopic IVP (Intravenous Pyelogram) …
- A Fluoroscopic VCUG (voiding cystourethrogram) …

What are imaging techniques?
Diagnostic imaging techniques help narrow the causes of an injury or illness and ensure that the diagnosis is accurate. These techniques include x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI).
What is meant by imaging techniques?
Definition. Imaging techniques are used to obtain a two-dimensional depiction of a surface or a three-dimensional reconstruction of a volume.
What is fluoroscopy imaging?
Fluoroscopy is a medical procedure that makes a real-time video of the movements inside a part of the body by passing x-rays through the body over a period of time. X-rays are a form of ionizing radiation.
Can I have an MRI with a dental bridge?
For patients undergoing an MRI (magnetic resonance imaging) procedure, they may be concerned about metal implants and how the imaging machine may affect them. Thankfully, dental implants and MRI procedures are a safe combination.
Which is more expensive MRI or CT scan?
Cost: CT scans are almost half the price of MRIs. The average computed tomography scan costs around $1,200 while an MRI is about $2,000. Speed: CT scans take much less time than MRIs. The exact time required depends on whether you need a contrast dye for the procedure, but MRIs always require more time for the scan.
