En hög lyckandefrekvens kan förväntas när varje steg i den endodontiska behandlingen utförs på ett adekvat sätt:

Tanden isoleras med kofferdam och ett aseptiskt arbetsfält upprätthålls under hela behandlingen för att förhindra kontaminering.

Kavumpreparationen utformas korrekt och tillåter en rak insättningsriktning för rotkanalsinstrumenten.

Instrumenteringen utförs under samtidig använding av kemiskt aktiva spolvätskor vilket avlägsnar mikroorganismer och löser upp nekrotisk vävnad.

Rotkanalerna försluts med en tät rotfyllning till adekvat längd, och den slutliga restaureringen utföres så snart som möjligt.

A successful outcome of the endodontic treatment is strongly associated with well performed treatment procedures. An adequate access cavity preparation which is correctly positioned, of adequate size and with straight-line access to the canals, is a prerequisite for the subsequent endodontic treatment procedures to be properly performed. Under aseptic conditions, after gaining access to the root canals, the working length is determined by electronic apex locator combined with radiographs, preferably after coronal flaring. The root canals are then cleaned and shaped, in the vast majority of cases rotary or reciprocating Ni-Ti instruments can be used. This is performed in conjunction with the use of an irrigation solution, usually sodium hypochlorite with a low concentration. Once the chemomechanical instrumentation has been thoroughly performed, the next essential step is filling of the root canals. A root filling of good quality, that is, ending within 2 mm from the radiographic apex and without any voids, is of significant importance for the outcome while the materials and techniques appear less important. Finally, the tooth should be permanently restored as soon as possible after root filling, to prevent fracture and reinfection. Provided that the treatment procedures have been adequately performed, high success rates can be expected.
