Remoción del barrillo dentario después de la preparación del espacio para el poste: requisito u omisión

Abstract

The long-term prognosis of endodontically treated tooth depends on proper final restoration that will prevent recontamination of the root canal system, while allowing effectively restore function and aesthetics in mouth.

Placement of posts in the root canal is indicated when the residual dental substrate is very limited, allowing the specialist to reconstruct tooth structure for the future restoration can be retained.

Several studies conclude at fiberglass post are one of the best ways to establish a safe anchorage between the tooth and restoration, which are retained within the root canal using resin cements in combination with adhesive systems.

This anchorage can be modified by various factors that can be dependent the choice operator's, chemomechanical protocols in endodontic therapy and at the time of preparation of post space; or independent from operator like the anatomy of the root, smear layer formation during unsealing, substrate adhesion, endogenous mechanisms and material behavior.

Therefore, the present study proposes a review of the variables whom the specialists confront to obtain an adequate post retention to the root canal with adhesive cements, proposing several irrigation protocols and auxiliary devices based on scientific evidence to help to neutralize adverse effects the operator can control.
