Endodontics deals with the diagnosis and the treatment of disease processes of the radicular dental pulp.
When a tooth suffers an irreversible damage in the nerve, due to tooth decay or a trauma, a root canal treatment (devitalization if the tooth is still living) has to be done.
In order to perform a correct canal treatment the radicular canals need to be cleaned, disinfected and enlarged, until they are closed again completely with specific materials.
The doctor needs to know the exact anatomy of the treated tooth, so it is necessary to have an x-ray image of the tooth.
Technology is once again useful with the peak detector, a sofisticated machine that informs you about the reaching of the apex in the dental canal by the instruments.
