Abstract

Aim In the present in vitro study, we investigated the time-related antimicrobial efficacy of Aloe vera and Zataria multiflora ( Z. multiflora) plant essential oils compared to calcium hydroxide ([Ca[ OH]<subscript>2</subscript>) to eliminate Enterococcus faecalis ( E. faecalis) from root canals. Methods A new strain of E. faecalis ( Enterococcus spp. AGH04) was isolated from a previously root-filled tooth with persistent apical periodontitis. The 16S rRNA sequence was analyzed and deposited in GeneBank under accession number . A total of 108 extracted human single-rooted teeth were contaminated with this bacterial strain and treated with Aloe vera essential oil, Z. multiflora essential oil, and Ca(OH)<subscript>2</subscript> for 1, 7, and 14 days. Gas chromatography-mass spectrometry (GC-MS) was used to determine the chemical composition of the oils. The percentage reduction from initial c.f.u./ mL counts were calculated and analyzed. Results Carvacrol, thymol, and linalool were the main constituents of both essential oils. The c.f.u./ mL count reductions significantly increased for all three medicaments when the contact time was extended. A statistically-significant difference was observed between the medicaments after 1 and 7 days, but there was no significant difference after 14 days. Conclusions Both medicinal herbs showed equal antimicrobial efficiency against E. faecalis, comparable to Ca( OH)<subscript>2</subscript> for the prolonged contact time of 14 days.
