What are the three types of intraoral radiographs?

What are the three 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 types of intraoral film?

The film typically used for the intraoral bitewing exam falls into three film speed classes – D (slowest), E and F-speed (fastest). Like photographic film, the faster the film, the less exposure it needs. Film speed can be an important aspect in determining the amount of radiation exposure received by a patient.

What are the different types of film in radiography?


  • base: cellulose triacetate or polyester.
  • substratum: an adhesive layer containing gelatin and solvents that bind emulsion and base.
  • emulsion: silver halide and gelatin, with some hardening agents.
  • protective layer: gelatin.

What are 4 Bitewings?

Bitewing images usually consist of four films, two on each side, which are necessary to capture all the back teeth — premolars and molars. Often only one bitewing image per side is required in smaller children.

What does intraoral mean?

Within the mouth
Intraoral: Within the mouth.

What does intraoral periapical mean?

The American Dental Association defines a bitewing radiograph as “interpoximal view radiograph of the coronal portion of the tooth” and a periapical radiograph as “a radiograph made by the intraoral placement of film for disclosing the apices of the teeth.”

What are five components of intraoral?

Terms in this set (29)

  • film base.
  • thin adhesive layer.
  • gelatin.
  • silver halide crystals.
  • protective layer.

What Colour are intraoral films?

The tube side is solid white and has a raised bump in one corner that corresponds to the identification dot on the X-ray film. When placed in the mouth, the white colour side of the film packet must face the teeth and the tube head.

What are the intraoral films used for?

An intraoral film is a film that is placed inside the mouth during X-ray exposure and is used to examine the teeth and supporting structures.

What is intraoral periapical radiograph?

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 intraoral periapical first film?

This dental procedure code, refers to a type of X-ray known as periapical. This term is used because these X-rays capture the entire tooth all the way down to the tissues at the tip of the tooth root – an area referred to as the periapical area.

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 are the different types of intraoral radiographs?

There are three main types of intraoral radiographs:  Periapical radiograph  Bitewing radiograph  Occlusal radiograph The anatomic area of interest and type of pathology suspected helps the clinician to decide the type of radiograph to be taken. Periapical radiograph

Which exposure techniques are used for Intraoral periapical radiography (IPR)?

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. This technique provides less image distortion and reduces excess radiation to the patient.

What are the different types of radiographic techniques in dentistry?

In dental practise, radiographic techniques are broadly classified into 2 types, namely Intra-Oral Radiography and Extra-oral Radiography. The most common types of Intra-Oral Radiographs include Intra-Oral Periapical Radiograph (IOPA Radiograph), Bitewing Radiograph as well as Occlusal Radiograph.

What is intra-oral periapical radiograph (Iopa)?

Intra-Oral Periapical Radiograph, also known as IOPA Radiograph, is most commonly used radiograph in the practise of dentistry. IOPA Radiographs are commonly used to detect any abnormalities of the tooth’s root structure & the surrounding bone structure.
