Abstract

Objective: Analyze the differences in inhibition zone diameter between 60% guava leaf extract (Psidium guajava linn.) and 100% lime juice (Citrus aurantifolia) when inhibiting the growth of Enterococcus faecalis bacteria.

Material and Methods: This study was a laboratory experimental method with post-test only control group design. Sampling with purposive sampling using 4 treatments and 5 repetitions. Statistical test used One-way ANOVA.

Results: The results of this study showed 60% guava leaf extract (Psidium guajava linn.) inhibited the growth of Enterococcus faecalis bacteria with a diameter of inhibition zone of 11.75 ± 0.680 while 100% lime juice (Citrus aurantifolia) had a a diameter of inhibition zone of 20.67 ± 2.655 mm, and based on statistical test determined p = 0.0046 < p = 0.05.

Conclusion: The alternative hypothesis of this study was accepted and the results of this study indicate that there was a difference of effectiveness between 60% guava leaf extract (Psidium guajava linn.) and 100% lime juice (Citrus aurantifolia) extract as root canal irrigation material that can inhibit bacterial growth of Enterococcus faecalis.
