What is an orthodontic radiograph?
Abstract. Seventy consecutive adolescents were examined to evaluate radiographic examinations as an aid to orthodontic diagnosis and treatment planning in combination with clinical examination. The clinical examination included dental impressions and extra- and intraoral photographs. The radiographic examination comprised a panoramic radiograph, a lateral …
What is the importance of X-rays in orthodontics?
May 27, 2020 · Radiographs are considered essential for orthodontic treatment. Among other indications, radiographs and cephalometric analysis are used for assessing the interrelationships among the maxillofacial skeleton, dentition, and soft tissues [1, 2].
Why are panoramic radiographs used in orthodontics?
Jun 06, 2021 · Figure 1 summarizes the use of radiographic techniques during the different stages of orthodontic treatment. The most frequently used techniques during all stages were panoramic, lateral, and periapical frontal radiography. The number of radiographs taken was considered as “just enough” according to 61% (82/134) of the respondents. FIGURE 1

Figure 1 summarizes the use of radiographic techniques during the different stages of orthodontic treatment. The most frequently used techniques during all stages were panoramic, lateral, and periapical frontal radiography.Jun 6, 2021
What are the two radiographs that are needed for orthodontic treatment planning?
For orthodontic treatment, we require two types of x-ray, a panoramic radiograph (OPG) and a Lateral Cephalogram.Sep 26, 2021
What is a cephalometric radiograph used for?
The cephalometric X-ray is a unique tool that enables the dentist to capture a complete radiographic image of the side of the face. X-rays in general offer the dentist a way to view the teeth, jawbone, and soft tissues beyond what can be seen with the naked eye.
What charts are required for orthodontic treatment?
Traditionally, dental models, facial and intra-oral photographs and a set of two-dimensional radiographs are used for orthodontic diagnosis and treatment planning. As evidence is lacking, the discussion is ongoing which specific records are needed for the process of making an orthodontic treatment plan.Nov 12, 2013
What charts and records would the dentist require for orthodontic treatment?
Radiographs, photographs, study models and 3D study models Records such as radiographs, photographs, visual recordings and study models, either as hard copies or in digital format, complement the written record. To be of value, these records must be of good quality.
What is cephalometric radiographic method and why it is used by orthodontists?
A cephalometric radiograph is a radiograph of the head which is taken in a Cephalometer. The Cephalostat is a head-holding device which was introduced in 1931 by Holly Broadbent Sr. The Cephalometer is used to obtain standardized craniofacial images which are available on radiographic films.
What are lateral oblique radiographs used for?
The lateral oblique x-ray view of the mandible and maxilla taken on an extra-oral film is a frequently used method for giving a record of the teeth in the buccal segments from canine to third molar show- ing the teeth both erupted and unerupted or to assess the positions of unerupted third permanent molars.
What is the difference between cephalometric and panoramic?
What is a Ceph? Cephalometric Analysis is an X-ray similar to a panoramic X-ray, in that it has the capability of capturing a full view of your skull and neck. A difference is that it is captured using a side-to-side sweeping motion, instead of the full 360 degree non-stop motion used in panoramic X-rays.
Why do we gather radiographs?
Radiographs are an important diagnostic tool in assessing an orthodontic condition and in determining a suitable treatment plan.#N#The two most common radiographs - although not exclusive - are the panoramic (OPG) and cephalometric views.
Are radiographs harmful?
You may have questions regarding the safety of x-rays used in orthodontic treatment.
How many x-rays should I expect to have taken?
The OPG and lateral cephalogram are the two most common x-rays gathered at the beginning of treatment. Occasionally other views will be necessary to adequately assess unusual morphology or pathology.
What if I refuse to have x-rays?
It is unlikely that treatment will be initiated unless adequate radiographic records are obtained. There is a very real danger to your teeth, jaws and overall well being if treatment is commenced without thorough diagnostic records.
Abstract
The aim was to investigate the objective and choice of different radiographic examinations used in orthodontic treatment of children and adolescents, using a web-based questionnaire directed toward specialists in orthodontics. The questionnaire was distributed to 255 orthodontists in Sweden.
INTRODUCTION
Many common dental radiographic examination techniques can be used for the assessment of teeth and jaws when planning and conducting orthodontic treatment. The risk associated with repeated exposures to radiation at an early stage in life is not negligible.
MATERIAL AND METHODS
Ethical approval for the study was obtained from the Regional Ethical Review Board, Gothenburg, Sweden (Dnr 847-18).
RESULTS
The questionnaires were collected between June and October 2017 and were followed by telephone interviews in October 2018. The response rate to the questionnaire was 57% (144 out of 255).
DISCUSSION
The findings from the questionnaire showed that panoramic radiography together with lateral and intra-oral radiography were preferred for treatment planning while intra-oral radiographs of the incisors were preferred during treatment and for follow-up.

What is a bitewing radiograph?
Bitewing Radiographs. These radiographs are typically routine screening radiographs taken on patients. One bitewing is taken for each side to assess the posterior teeth. These are usually done in a horizontal manner, however they can also be done vertically to gain some more information. Right bitewing.
What is periapical radiograph?
Ectopic teeth – periapical radiographs can be used to identify and localise ectopic teeth using a parallax technique (where 2 periapicals are taken in different positions to assess the location).
What is a PA skull view?
PA skull views are helpful in assessing for pathology of the skull, such as Paget’s disease, or fractures of the skull vault. For this type of image, the patient sits facing the x-ray film with their forehead and the tip of their nose touching the film.
What is OM view?
OM views are usually taken to assess fractures of the midface or sinus pathology. As we are usually assessing fractures with this view, we typically take it from two angles.
What is an IRMER operator?
IRMER Operators are responsible for conducting any practical aspect of a medical exposure including exposing the radiograph or processing the image. tIRMER Operators and IRMER Practitioners must have received adequate training. tIRMER Operators and IRMER Practitioners must undertake continuing education.
What is stochastic effect?
Stochastic effects are the chance or random effects, governed by the laws of probability, that patients may develop from any dose of radiation. In dental X-ray imaging, the risk of heritable (genetic) effects is considered negligible, so the stochastic effect of concern is the risk of cancer induction.
Is ionising radiation dangerous?
As a result, the use of ionising radiation in clinical practice is governed by law criminal law in the UK . Ionising radiations, including X-rays, are dangerous and have the potential to cause damage to human tissue, including fatal malignant change. Radiographic examinations put patients at risk.
