Endodontics is a treatment that involves removing deep in the tooth when the area is damaged. The therapy is indicated when there is a widespread decay or tooth fracture that caused an inflammation or death of the dental pulp. The goal of endodontics is to maintain the healthy tooth to be useful for chewing, avoiding having to remove the tooth. The technique involves removing the nerve, clean the root canal and then seal it with a thermoplastic material ( gutta percha ) and cement or other material fillings. Subsequently, various radiographs are necessary to ensure the accuracy of the result. The term endodontic also used as a synonym for Endodontology, a branch of stomatology that deals with diseases of the dental pulp.
