Factors affecting retention of post systems: a literature review.
BACKGROUND
An extensive review of the published literature has revealed a wide divergence of opinion regarding the suitability of different post systems for endodontically treated teeth. As a result, the dentist has no clear guidelines concerning the selection of suitable post systems that will provide adequate retention while minimizing subsequent root fracture.


OBJECTIVE
This study formulated, through the literature search, a set of guidelines to assist the dentist in selecting an endodontic post system that would optimize retention while limiting root fracture.


RESULTS
For most clinical situations, the literature indicates that a passive parallel-sided post will, in the hands of the average practitioner, allow the dentist to successfully restore most endodontically treated teeth.
