[SEM evaluation of a new system of intracanal anchorage for reconstruction of endodontically treated anterior teeth].
The Authors investigated a new kind of parallel-sided cylindrical posts used for anterior teeth (Triax--Whaledent Inc.--New York NY). Twenty-four freshly extracted maxillary incisors were selected for the study. Root canal therapy was performed and post-space prepared to receive the prefabricated post. Cementation of the posts was carried out using zinc phosphate cement and silver glass ionomer cement. Light cured composite, self curing composite and silver glass ionomer cement were used as cores materials. The specimens were examined under a scanning electron microscope. These new prefabricated posts luted with silver glass ionomer cement presented a gap at the dentin-cement and post interface similar to the cast posts luted with zinc-phosphate cement. The core material was in all the three different types of construction well adapted to the post head.
