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.
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.
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 two techniques for exposing radiographs?
There are two types of techniques used for periapical radiographs: bisecting angle, and paralleling.
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.
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 intraoral radiographic technique?
Intraoral radiographs still remain one of the most important imaging modalities available in dentistry to the dental practitioner. The intraoral technique provides high spatial resolution imaging of teeth and potential associated dental and jawbone diseases.
What technique is used for exposing radiographs?
The technique used for exposing dental images is done as a parallel or bisecting angle image. A parallel technique is when a film is placed parallel…
What is intraoral imaging?
Intraoral cameras (IO cameras) produce accurate images of teeth and the supporting structures, allowing patients to see problems with their teeth and/or gums including tarnished or corroded fillings, fractured teeth etc.
What is intraoral periapical images?
Intraoral periapical radiographs (IOPAR) are widely used for the preoperative planning and evaluation for most minor oral surgical procedures owing to it simplicity, significantly lower cost, less radiation exposure and easy availability in a dental clinical set-up.
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 are the three 3 main principles of the paralleling 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 …
Why is exposure sequencing so important when obtaining radiographs?
When exposing radiographs, establish an exposure sequence, or definite order for periapical film placement. Without an exposure sequence, there is a good chance that you will omit an area or expose the same area twice.
What is intra oral radiography?
There are two main types of dental X-rays: intraoral (the X-ray film is inside the mouth) and extraoral (the X-ray film is outside the mouth). Intraoral X-rays are the most common type of X-ray. There are several types of intraoral X-rays. Each shows different aspects of teeth.
How do you take an intraoral radiograph?

What are 3 types of intraoral radiographs?
There are three types of diagnostic radiographs taken in today's dental offices — periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric.
What are the three types of intraoral imaging examinations?
Intraoral radiographic examination is the backbone of imaging for the general dental practitioner. It comprises of three categories: periapical, bitewing and occlusal projections.
What is intra oral radiographs?
There are two main types of dental X-rays: intraoral (the X-ray film is inside the mouth) and extraoral (the X-ray film is outside the mouth). Intraoral X-rays are the most common type of X-ray. There are several types of intraoral X-rays. Each shows different aspects of teeth.
When exposing images in which area of the mouth should you begin?
Begin the full mouth series with the maxillary central incisor region. Patients usually tolerate this x-ray well. The sensor is inserted vertically into holders. The beam should pass perpendicularly to the sensor plane, and the sensor should be at a 90º angle to the interproximal maxillary central incisor area.
What are the five basic rules of the paralleling technique?
5 Basic Rules for the Paralleling Technique
- Flashcards. Review terms and definitions.
- Learn. Focus your studying with a path.
- Test. Take a practice test.
- Match. Get faster at matching terms.
What is radiographic exposure?
Exposure describes the ability of x-ray photons to ionize air and cannot be used for protons, neutrons or electrons. Exposure decreases with the square of the distance from an x-ray source (inverse square law).
What are intraoral images?
Intra-oral photos are photos that are taken of your teeth, gums and oral tissue. These photos may be of a single tooth, a group of teeth, or any area of your mouth. At our office, photos are taken with a small, high quality digital camera that moves comfortably within your mouth.
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.
What are the 3 types of intraoral radiographs?
Types of Intraoral X-Rays
- Bite-wing X-rays show details of the upper and lower teeth in one area of the mouth. …
- Periapical X-rays show the whole tooth — from the crown to beyond the end of the root to where the tooth is anchored in the jaw. …
- Occlusal X-rays are larger and show full tooth development and placement.

When placing and exposing radiographs the dental radiographer must wear?
Copyright 2003, Elsevier Science (USA). All rights reserved. Gloves and protective clothing must be worn while exposing radiographs and handling the contaminated films.
Why is the sequence 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 are the 4 exposure factors?
The quantity and quality of the x-ray beam are controlled by four prime factors. These factors are under the direct control of the limited operator. The prime factors of exposure are milliamperage (mA), exposure time (S), kVp, and SID.
What is high kV technique?
Contrast control Hence the high kV technique of the chest x-ray is employed to present a more uniformly dense image to better appreciate the lung markings. A 15% increase in kV will essentially correlate to an increase in density similar to double the mAs 2.
What are the three types of dental images?
There are three types of diagnostic radiographs taken in today's dental offices — periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric. Periapical radiographs are probably the most familiar, with images of a few teeth at a time captured on small film cards inserted in the mouth.
