Comparative evaluation of sealing ability of gutta percha and resilon as root canal filling materials- a systematic review

Abstract

This systematic review aims to comparatively evaluate the sealing ability gutta-percha and resilon as root canal filling materials. A Medline search was conducted to identify in-vitro studies published between October 01, 2004 and October 01, 2019, conducted on human extracted teeth, published in English and testing the sealing ability of gutta-percha and resilon as root canal filling materials using fluid filtration method. The search identified fifty-five published articles. After a thorough screening, five articles meeting the selection, and validity assessment criteria were critically appraised. The results indicated that during the initial time-period, resilon/epiphany sealer has better sealing ability than gutta-percha. However, over a period of time the resilon system demonstrated increased fluid flow. Gutta-percha with AH plus sealer showed the best long term sealing ability.
