The Antibacterial Effect of Calcium Hydroxide Modified with Dragon Blood Tree Extract Compared to other Intercanal Medicaments and Their Effect on Crown Discoloration and Dentin Microhardness: An In Vitro Study

Abstract

The main goal of an endodontic treatment is complete removal of bacteria, their byproducts, and pulpal remnants from infected root canals and the complete sealing of disinfected root canals. Intracanal medicaments have been thought as an important step in killing the bacteria in root canals The purpose of this study was to evaluate and compare the antibacterial effect of calcium hydroxide modified with dragon blood tree extract compared to conventional calcium hydroxide paste and triple antibiotic past when used as intracanal medicament in extracted primary teeth contaminated with E. faecalis bacteria then study its effect on dentin microhardness and crown discoloration. Total eighty eight extracted, primary anterior used in this study : Regarding antibacterial test against E. faecalis 32 extracted, primary anterior were decoronated and only the roots were used in this study, randomly divided into five groups; three experimental groups, one positive control group and one negative control group as follows: conventional calcium hydroxide group: consisted of 8 roots that were contaminated and medicated with conventional calcium hydroxide paste, modified calcium Hydroxide group: consisted of 8 roots that were contaminated and medicated with modified calcium hydroxide paste, TAP group : consisted of 8 roots that were contaminated and medicated with TAP , Positive control group: consisted of 4 roots that were contaminated but not medicated and negative control group: consisted of 4 roots that were not contaminated nor medicated.
