Success or failure of endodontic treatment

Success or failure of endodontic treatment


A tooth nerve can occur without pain again. Pain that may occur is caused by pressing on that tooth during chewing or food or tooth percussion tests.

There are two possibilities:

Success or failure of endodontic treatment

1. Pain immediately after the completion of treatment

This pain is often of low intensity, can be an "embarrassment" to push the tooth and is caused by irritation of the tissues surrounding the root tip. At canal treatment tooth tissues around the root tip may be irritated by the tools and materials used, and can appear minimal inflammation that causes pain when the pressure on the tooth, the tooth is a rigid structure, in turn presses on this area . This sensitivity will disappear slowly a few days after the treatment. If pain intensity is disturbing anti-inflammatory and analgesic can be administered for the first few days after surgery.

This treatment may develop into a success or to failure.

The success of endodontic treatment depends on:

• the initial state of the tooth treated (infected, uninfected, previous treatments) and tissues surrounding the root;
• shape and architecture of the root canals (curved, narrow, hidden);
• Bonding quality physician performed the root canals (materials, equipment, technology);
• quality restorations on tooth crown must fully sealed inside the tooth by saliva penetration is a huge reservoir of bacteria.

2. The pain occurs after a long period from completion of treatment.

This pain indicate treatment failure.

Endodontic treatment failure is caused by bacteria:

• remaining hidden and inaccessible channels located in the root of the tooth;
• remaining gaps that may occur in endodontic obturation;
• permeated by cracks in the root (filling) of the tooth crown and root where the gaps are in the root canal tooth tip inflaming reach tissues around the root tip;
• permeated by fractures occurred in the tooth after it has been treated. Treated tooth fractures may occur due to large forces that develop especially on molars (masses) during chewing of food or bruxism (teeth scasnirea). For dinetele who presented initially large cavities, your dentist may recommend sanding it and cover it with a crown to increase its strength and to better protect the infiltration of bacteria in saliva.

Statistical studies show that the success rate of endodontic treatment is between 70-95% [1, 2, 3].

Success rate of endodontic treatment can be increased by following a proper protocol for the preparation of root canals (disinfection, stretching), filling the entire space as good inside the tooth and, respectively, cover the tooth with a crown (tooth grinding and cementation of crowns made in the dental laboratory technician realized).
