Introduction : Caries is a growth medium for pathogenic micro-organisms an
inflammatory process can occur which can cause damage to the tooth pulp.
Enterococcus faecalis one of the Gram-positive facultative anaerobes which causes
failure after endodontic treatment. In the field of dentistry, herbal ingredients can be
used as alternative medicinal ingredients because the ingredients is tamarillo skin
which contains flavonoids, terpenoids, saponins and phenol compounds. In addition
to herbal alternatives, endodontic filling also uses ingredients that have antibacterial
potential that can kill and prevent reproduction in the root canals, one of which is
the zinc oxide eugenol sealer which is usually applied together with gutta percha.
Research objective: to determine the effectiveness of the extract of tamarillo
(Solanum betaccum Cav.) skin sealer combination in inhibiting the growth of
Enterococcus faecalis. M ethod: The research was conducted in an experimental
laboratory post test only control group design. Results : a sealer made from zinc
oxide-eugenol had the largest diameter compared to the combination group of 100%,
75%, 50%, 25% tamarillo skin extract with sealer, and aquadest. Based on the One
Way Anova test, there was a significant difference in the mean diameter of the
inhibition zone (p <0.05) and the Post Hoc LSD analysis test showed that the sealer
was the best group to kill the Enterococcus faecalis bacteria. Conclusion : sealers
have a good effect on inhibiting Enterococcus faecalis bacteria as a cause of failure
in endodontic treatment.
