Evaluation of antimicrobial activity and efficacy of herbal oils and extracts in disinfection of gutta percha cones before obturation.

Objectives: Literature has shown that micro-organisms contaminate gutta percha (GP) during storage and manipulation. Till date herbal extracts are not explored as an alternative medicament for pre-operative chairside disinfection of GP cones. The purpose of our study was to evaluate the antimicrobial activity and efficacy of lemon grass oil (LG), basil oil (BO), and obicure tea extract (OT) in disinfecting GP cones before obturation.

In vitro evaluation of the antimicrobial efficacy of chitosan and other endodontic irrigants against Enterococcus faecalis.

The success of endodontic treatment is directly enhanced by elimination of microorganisms in infected root canals. Recently, chitosan, a natural, nontoxic biopolymer, has been introduced as an irrigant that has the capacity to remove the smear layer. The antimicrobial properties of chitosan as an endodontic irrigant have not yet been explored.
