Dentists to study mouth related diseases use intraoral radiography. It allows dentists to look inside the mouth and study structures below the gum line. Intraoral radiography allows dentists to reveal tooth related diseases such as abnormal tooth or unexpected bleeding. It also helps to find the presence of unrequited teeth

Intraoral radiography films can show full length of tooth. This technique is also useful to show periapical tooth in two-millimeter dimension. Dentists can find entire lesions in this film, so it helps dentists to find out any problem in the tooth.

Modern Intraoral radiography is based on parallel technique. In this technique, an x-ray film is parallel to the long axis of the tooth and the X-ray beam is targeted at 90 degree to the tooth and film. This method has very little geometric limitation, so it gives accurate representation of the shape and size of the studied structures.

Bisecting technique is used when this film cannot be fit into a parallel direction to the tooth’s surface. In bisecting technique the X-ray beam targeted at the right angled to the imagery line that divide the angle made by the film in two equal parts and long axis of the tooth. In this bisecting technique, a 45-degree angle plane is used. Roots of the incisors and canines can be seen after targeting 20 degree X-rays to the film plane

There are several other methods involved in developing Intraoral Radiography films such as hand tank, chemicals and timing. Automatic processor is useful to get larger films. This technique is quick and most pathologists use this method to get larger films in one minute. This technique used to develop films in dark rooms with the help of chemicals. To increase safety for developing dental images, most of the dentists recommend using dental operatory. This technique will avoid unnecessary time used in the hospital darkroom. Intraoral Radiography is used to develop dental images within 10 to 20 seconds. Development of images will depend on the chemicals used in this process. Once this process is over, images are to be kept in water for some time for permanent record.
