Effect of Post-Space Preparation on Apical Seal of Endodontically Treated Teeth

By restoration of pulpally exposed teeth with root canal therapy edentulous areas and neighbouring teeth displacement can be avoided. Prefabricated posts may be used for crown restoration of these teeth. For the preparation of root canal for post placement, Gutta percha should be removed by means of mechanical, thermal and chemical agents. To study the amount of apical leakage in vitro, three methods have been compared: 1. not plugger. 2. gates glidolen and 3- peeso reamer, in 60 human single extrated root teeth, (earning at least 5mm gutta-percha at apical third). Result showed significant difference between 3 methods. Highest leakage observed in peeso remer group (4.669mm), and least leakage seen in hot plugger group (1.945mm), and in gates glidden group (3.843mm). The result of this investigation shows that hot plugger is appropriate instrument for removal of gutta-percha from tooth root canal system.
