AIM: In this work it has been evaluated how the use of an endocanalar brush (post-brush) is able to clean the post-space macroscopically and eliminate permanently any debris, leading to the determination of an enhancement of the dentine-cement interface adhesion. The retentive power of cylindrical-grooved in two different groups of dental elements (A GROUP and B GROUP) will be compared, cementing A group according to standard protocol and B group with treatment of Post-Brush.
METHODS: Forty monoradicular elements were selected to carry out this experimental work. The roots were treated endodontically. Samples were divided randomly into two groups. For each group was used a different type of cementation. These tests were performed through the use of an electronic dynamometer. The samples were subjected to tensile strength to obtain a axial traction shear-stress and a subsequent separation of sample postreconstruction from root canal, at a loading maximum value recorded by the dynamometer right after the detachment.
RESULTS: B GROUP, which included cemented cylindrical-rubbed posts before treatment of Post-Brush, has shown a tensile shear-stress at break performances higher than that A GROUP, in which cylindrical-rubbed posts have been cemented according to the standard protocol.
CONCLUSION: Post-brush allows to obtain a better mechanical cleaning, going to remove gutta-percha residues, smear-layer and endodontic cement, which remain adhere on the canal walls otherwise they will not be removed completely by the use of the etching and the washing techniques as it tends to adhere to the canal walls.
