What are the types of orthodontic x-rays?
- Cephalometric radiograph. Cephalometric x-ray, also known as lateral ceph, is one of the essential types of dental x-ray used in orthodontics.

Which radiographs are best for orthodontics?
The radiographic examination comprised a panoramic radiograph, a lateral cephalogram and six intraoral anterior periapical radiographs. Initially, only records from the clinical examination were used for diagnosis and treatment planning. If required, the dentist could choose any of the radiographs to accomplish the task.
What is the importance of X-rays in orthodontics?
The cephalometric radiograph is an invaluable adjunct to the clinical examination and models of the dentition, which together form the basis for orthodontic diagnosis and treatment planning.

What is cephalometric radiography?
Cephalometric x-rays (also called ceph x-rays or radiographs) show a side view of your head, exposing teeth, jaw, and surrounding structures. This technology is considered safe and often useful or necessary to help professionals evaluate and assist patients.
What is a lateral cephalometric radiograph?
A lateral cephalometric radiograph (LCR) is a standardised, reproducible radiograph used primarily for orthodontic diagnosis and treatment planning. It is taken from a distance of 1.5m with the head at a right angle to the X-ray beam at a distance of 30cm, (although this has been found to vary slightly).Mar 3, 2015
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 diagnostics records are indicated for an orthodontic consultation?
If it is determined that orthodontic treatment is indicated, you will be scheduled for diagnostic records. These records usually consist of study models, diagnostic photographs and orthodontic x-rays.
What is occlusal radiography?
An occlusal radiograph is a radiograph designed to be placed between the occlusal surfaces of the teeth with the central beam directed at 90o or at 50 -60o to the plane of the film depending on what is required to be viewed.
What extraoral radiograph is used to best see the maxillary sinus?
Bregma–menton viewiv. Bregma–menton view. This projection is primarily used to demonstrate the walls of the maxillary sinus (especially in the posterior areas), the orbits, the zygomatic arches and the nasal septum.Apr 11, 2016
What is a Cephalogram used for?
The lateral cephalogram shows facial structure, bone, and soft tissue. Your radiologist or dental practitioner can use these images to study the relation of your teeth to your jaw, assess problems in alignment or growth patterns, and prepare treatment.Sep 28, 2015
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.

How many chances of developing cancer in Orthodontic patients?
ICRP currently estimate that there is a 1 in 20,000 chance of developing a fatal cancer for every 1 mSv of effective dose of radiation.
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.
What are the different types of dental x-rays?
There are 4 common types of dental x-rays: Bitewings. Periapicals. OPG / Panoramic X-ray. CT-Scan. 1. Bitewings are x-rays taken of your back teeth biting together on the left and right sides. These are used to check for tooth decay in between teeth, and bone levels around teeth. They do not show the roots of the teeth.

You can’t accurately diagnose early tooth decay on an OPG. They are great for general survey. 4. CT Scan – these are a 3D view of the upper and lower jaws. These are great when doing implant surgery and you want to use 3D planning software. They are however high in radiation and so should only be used when needed.
