"Enterococcus faecalis adalah bakteri yang paling dominan pada kasus infeksi pasca perawatan endodontik. Telah diteliti aktivitas fenotipnya (kemampuan membentuk biofilm dan Gel E serta viabilitasnya terhadap NaOCL dan khlorheksidin) dan profil genotipnya. Ternyata tidak ada perbedaan aktivitas Gel E E. faecalis saluran akar dan saliva pasien pra dan pasca perawatan. Dalam membentuk biofilm, kemampuan E. faecalis saluran akar pra-perawatan lebih kuat daripada pasca-perawatan, sedangkan kemampuan E. faecalis saliva tidak berbeda. Viabilitas E. faecalis menurun jika kadar NaOCl dan khlorheksidin meningkat; 30 menit adalah waktu inkubasi efektif. Terdapat keragaman profil genotip antara E. faecalis saliva dan saluran akar, pra dan pasca perawatan.

Enterococcus faecalis is strong dominance bacteria in post treatment endodontic disease. Its phenotype activity (its ability to produce biofilms and Gel E also its viability to NaOCL and chlorexidine) and its genotype profile has been observed. It turns out that there?s no difference in E. faecalis Gel E activity of root canal and saliva from pre- nor post-endodontic treated patients. In producing biofilms, the ability of E. faecalis pre-endodontic treated root canal was stronger than the postendodontic treated root canal, while the ability of E. faecalis from saliva have no difference. The viability of E. faecalis decline if the concentration of NaOCl and chlorexidine were increasing; the effective incubation time was 30 minutes. There?s various genotype profile between E. faecalis of saliva and root canal either pre- or post-endodontic treatment."

"Latar Belakang: Perawatan endodontik bertujuan untuk menghilangkan infeksi mikroba yang terlibat pada sistem saluran akar. Enterococcus faecalis merupakan spesies yang terlibat dalam infeksi endodontik. E. faecalis memproduksi enzim gelatinase yang dapat membantu untuk menempel pada permukaan dentin. Propolis dikenal kaya akan bahan aktif sehingga berpotensi menjadi bahan alam untuk menunjang perawatan endodontik. Tujuan: Menetapkan efektivitas propolis 0.2%, 0.8%, dan 1.2% jika dibandingkan dengan NaOCl 5.25% serta pengaruhnya terhadap ekspresi gen gelE pada biofilm E. faecalis dan aktivitas gelatinase. Metode: Eksperimen biofilm ditumbuhkan pada 96­-well plate dan diinkubasi dalam keadaan microaerofilik selama 14, 48, dan 72 jam dan selanjutnya dilakukan uji ekspresi gen gelE dengan RT-qPCR serta uji gelatinase dilakukan pada BHI agar yang dicampurkan dengan 3mg susu skim yang dibentuk sumuran setelahnya diinkubasi selama 3, 9, dan 24 jam Hasil: Pada hasil penelitian didapatkan hasil secara kualitatif pengamatan mikroskopik adanya efektivitas propolis terhadap E. faecalis seiring dengan bertambahnya konsentrasi pada masa inkubasi 24 dan 48 jam. Dari hasil uji statistik Kruskall wallis dengan menggunakan GraphPad, ekspresi mRNA gelE dipengaruhi oleh propolis jika dibandingkan dengan kontrol negatif , hasil uji statistik didapatkan hasil yang signifikan (p < 0.05). Berdasarkan hasil dari uji gelatinase didapatkan diameter zona bening propolis 0.2%, 0.8%, dan 1.2% lebih kecil jika dibandingkan dengan kontrol negatif dan akuades secara berurutan, akan tetapi lebih besar jika dibandingkan dengan NaOCl 5.25% selaku kontrol positif. Kesimpulan: Propolis berpotensi menjadi bahan medikasi dan irigasi pada perawatan endodontik, selanjutnya perlu dilakukan penelitian lebih lanjut dengan bakteri multispesies dan konsentrasi propolis yang lebih tinggi.

Background: Endodontic treatment aims to eliminate the microbial infection involved in the root canal system. Enterococcus faecalis is a species involved in endodontic infections. E. faecalis produces gelatinase enzymes that can help to adhere to the dentin surface. Propolis is known to be rich in active ingredients so that it has the potential to be a natural ingredient to support endodontic treatment. Objective: To determine the effectiveness of propolis 0.2%, 0.8%, and 1.2% when compared to 5.25% NaOCl and their effect on the expression of the gelE gene in E. faecalis biofilm and gelatinase activity. Methods: Biofilm were grown on a 96-well plate and incubated under microaerophilic conditions for 14, 48, and 72 hours and then tested for gelE gene expression using RT-qPCR and gelatinase test was performed on BHI agar mixed with 3mg of skim milk formed The wells were then incubated for 3, 9, and 24 hours. Results: The results obtained qualitatively microscopic observations of the effectiveness of propolis against E. faecalis along with increasing concentrations during the incubation period of 24 and 48 hours. From the results of the Kruskall Wallis statistical test using GraphPad, the expression of gelE mRNA was affected by propolis when compared to the negative control, the statistical test results obtained significant results (p < 0.05). Based on the results of the gelatinase test, the diameter of the clear zone of propolis 0.2%, 0.8%, and 1.2% was smaller than the negative control and distilled water respectively, but larger than the 5.25% NaOCl as the positive control. Conclusion: Propolis has the potential to be a medicinal and irrigation material in endodontic treatment, further research needs to be done with multispecies bacteria and higher concentrations of propolis"

Background: E. faecalis and C. albicans are microorganisms in root canals that are able to survive even after root canal treatment. The use of synthetic irrigation solutions during root canal treatment is effective in eliminating microorganisms in the root canal but has been shown to be toxic to periapical mesenchymal stem cells. Apple vinegar contains active substances such as organic acids, flavonoids, phenols, tannins which are antimicrobial and inhibit microbial growth, but have been proven not to be toxic to stem cells. The aim of this study was to compare the antimicrobial effects of apple vinegar solutions of various concentrations on E. faecalis and C. albicans biofilms. Method: Exposure to 0.63%, 1.25% and 2.5% apple vinegar solutions, as well as 2.5% NaOCl positive control and negative control on E. faecalis and C. albicans biofilms were carried out. Then the antimicrobial effect was evaluated using the colony count test and viability value using the MTT Assay method. Result: There were significant differences in the number of colonies and viability values of E. faecalis biofilm (p<0.05) and C. albicans biofilm (p<0.05) between all concentrations of apple vinegar solution, positive control and negative control, with the antimicrobial effect of the apple vinegar solution were highest at a concentration of 2.5% and lowest at a concentration of 0.63%. Conclusion: The 2.5% apple vinegar solution has antimicrobial ability with viability values and colony numbers almost comparable to the 2.5% NaOCl as positive control, so 2,5% apple vinegar solution can be considered as an alternative root canal irrigation solution."
