Abstract

Enterococcus faecalis is one of bacteria which have resistance against the pulp tissue defense mechanism and often
found in endodontic infections. This bacterial is may hold good colonization, can survive in the root canal without
other bacteria, and is capable of producing toxins directly or through the induction of inflammation. Betel leaf (Piper
betle Linn)contain essential oils, as the main components of the essential oils are phenols and compounds, among
other derivate such as kavikol compound that has bactericidal five times stronger than phenol. Phenol disrupts three
dimensional structure of the bacterial protein to be a random structure and denatured protein, and damages biological
activity. Chlorhexidine has been shown to be effective against Enterococcus in the root canal irrigation. Betel leaf can
be chosen as an alternative material root canal irrigation saline. This in vitro experimental laboratory study is aimed
to determine the effectiveness of anti-bacterial extracts of betel leaf for E.faecalis bacteria. The minimum inhibitory
concentration of betel leaf extract is determined by observing the lowest concentration that was first seen clearly,
namely 20%. The assay method of these anti-bacterial effect used diffusion method to comparing the inhibition zone
betel leaf extract solution in concentration of 20% be compared 0.2% chlorhexidine, 2% chlorhexidine, and distilled
water. Each group performed eight times repetition respectively. Data analysis used one way anova test followed by
LSD test. From this research, it was concluded that 2% chlorhexidine has antibacterial effect for E.faecalis better than
betel leaf extract and 0.2% chlorhexidine.
