Popularly Endodontics is known as “Treatment of Nerve”, which is a misnomer for two main reasons: (1) the objective is to eliminate and not try (to recover ) “nerve” inside the tooth and in reality (2) thus eliminating not only the nerve but the dental pulp, which hosts this and other important components such as arteries, veins and lymph vessels, confirming that the teeth are independent bodies.
Endodontology The word is derived from the Greek language and can be translated as “knowledge of what is inside the tooth”. That is why it Endodontics involves all structures and processes in the niche pulp (pulp cavity containing). The pulp chamber is a sterile site surrounded by rigid walls of the tooth , isolation from saliva, which is not sterile; endodontics is usually required when organisms invade the enclosure through caries, trauma or fractures.
Once contaminated pulp is necessary to remove and clean the site where it is to prevent or heal pathological conditions of the surrounding tissues. A root canal is never finished until the tooth is permanently restored, otherwise the treatment may fail also endodontics is the last resort to save and maintain the natural tooth in the mouth.
It is important that the patient understands that the loss of a tooth is extremely detrimental to the whole apparatus of mastication as the same bite force is distributed in fewer teeth, resulting in major problems in the medium and long term, for example teeth “corridos”, “holes” or gaps in the smile, loss of stability in the bite (occlusal trauma), problems in the jaw joint, headaches, among others.
