Abstract:

ABSTRACT  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.

Effect of smear layer on the apical seal of endodontically treated teeth: an ex vivo study.

AIM The purpose of this study was to evaluate the effect of smear layer on apical seal of endodontically treated teeth. MATERIALS AND METHODS Sixty freshly extracted human maxillary central incisor teeth were selected and were randomly divided into two experimental groups. Group A of 25 teeth and group B of 25 teeth and a control group of 10 teeth. Cleaning and shaping of the root canals were...

Effect of post space preparation on apical seal: influence of time interval and sealer.

OBJECTIVE To assess the efficacy of two sealants to preserve the apical seal after root canal preparation and cementation of posts at 24 h or 72 h after endodontic treatment. STUDY DESIGN Sixty human single-root teeth were instrumented and obturated using lateral compaction technique with EndoFill [30] or AH-Plus) [30] and were prepared in one of three ways, leaving a 3 mm gutta percha remnan...

Apical Microleakage of Different Luting Agents in Endodontically Treated Teeth Restored with Para-post System

Endodontically treated teeth are known to present a higher risk of biomechanical failure than vital teeth. Complete obturation of the root canal system to the cementodentinal junction is assumed to be an important goal in endodontic treatment. The microleakage is determined today by many in vivo and in vitro techniques such as; staining, measurement by scanning electron microscope, bacterial ac...

The effect of post type and length on the fracture resistance of endodontically treated teeth.

STATEMENT OF PROBLEM Few studies have been conducted to determine a correlation between the flexural modulus of metal and fiber-reinforced posts and the fracture resistance and failure mode of teeth restored with posts. Questions remain as to whether a longer post length or a post with a higher flexural modulus will significantly improve the fracture resistance of a tooth restored with a prefab...
