An in-vitro comparative study of the retention of grooved and flat endodontic posts in treated root canals using two different types of cements.

Abstract
This study evaluated and compared the retentive capability of performed cast posts in endodontically treated premolar teeth using the following: 1--smooth versus grooved post design 2--surface treatment of the root canals with either 17% EDTA followed by 2.25% Naocl or using Naocl only. 3--cementation of the posts with either polycarboxylate cement or C & B Metabond. Cast metal posts were made, cemented in root canals and divided into groups representing combinations of variables. The force required for post removal were recorded and statistically analysed. The results indicated that cementation of the grooved cast metal post with polycarboxylate cement after removal of the smear layer was the most retentive system. More over C & B Metabond resin cement with any post design in presence or absence of smear layer gave high retentive values.
