A comparative evaluation of fracture resistance of endodontically treated teeth restored with different post core systems - an<i>in-vitro</i>study

Abstract

Endodontically treated teeth without post core system showed the least fracture resistance demonstrating the need to reinforce the tooth. Stainless steel post with composite core showed the highest fracture resistance among all the experimental groups. Teeth restored with the Glass fiber post showed the most favorable fractures making them more amenable to the re-treatment.
