"Latar belakang: E. faecalis merupakan bakteri yang mendominasi lesi periapikal persisten dengan prevalensi 22-77%. Beberapa penelitian menunjukkan MTA tidak memiliki aktivitas antibakteri terhadap E. faecalis, yang diketahui memiliki kemampuan untuk membentuk biofilm, menginvasi tubuli dentin, mempertahankan viabilitas dalam kondisi tanpa nutrisi dan pH basa yang esktrim. Kitosan telah terbukti efektif melawan beberapa mikroorganisme rongga mulut, salah satunya E. faecalis. Kitosan larut air merupakan turunan kitosan yang menunjukkan aktivitas antibakteri pada pH yang lebih luas. Tujuan: Penelitian ini akan menganalisis pengaruh penambahan kitosan larut air 5% dan 10% pada MTA terhadap kemampuan antibiofilm E. faecalis.
Metode: Tiga kelompok penelitian, yaitu MTA, MTA dengan penambahan kitosan larut air 5%, dan MTA dengan penambahan kitosan larut air 10%, dibuat menjadi ekstrak dan dipaparkan pada biofilm E. faecalis. Kemampuan antibiofilm ditentukan melalui nilai viabilitas biofilm E. faecalis yang didapatkan dari nilai densitas optik uji MTT assay.
Hasil: Terdapat perbedaan bermakna (p<0,05) nilai viabilitas biofilm E. faecalis antara kelompok semua kelompok. Kelompok MTA dengan penambahan kitosan larut air 10% memiliki nilai viabilitas biofilm E. faecalis yang paling rendah, diikuti oleh MTA dengan penambahan kitosan larut air 5%, dan MTA. Kesimpulan: Penambahan kitosan larut air berbagai konsentrasi pada MTA meningkatkan kemampuan antibiofilm terhadap E. faecalis. MTA dengan penambahan kitosan larut air 10% menghasilkan kemampuan antibiofilm tertinggi terhadap E. faecalis secara signifikan dibandingkan dengan MTA dan MTA dengan penambahan kitosan larut air 5%.
Background: E. faecalis is the dominant bacteria in persistent periapical lesions with a prevalence of 22-77%. Several studies have shown that MTA has no antibacterial activity against E. faecalis, which is known to have the ability to form biofilms, invade dentinal tubules, maintain viability in conditions of no nutrition and extreme alkaline pH. Chitosan has been shown to be effective against several oral microorganisms, one of which is E. faecalis. Water-soluble chitosan is a chitosan derivative that shows antibacterial activity at a wider pH.
Objective: This study will analyze the effect of adding 5% and 10% water-soluble chitosan to MTA on the antibiofilm ability against E. faecalis. Methods: Three research groups, namely MTA, MTA with the addition of 5% water-soluble chitosan, and MTA with the addition of 10% water-soluble chitosan, were made into extracts and exposed to E. faecalis biofilms. Antibiofilm ability was determined by the value of the E. faecalis biofilm viability obtained from the optical density value of the MTT assay test. Results: There was a significant difference (p<0.05) in the value of E. faecalis biofilm viability between all groups. The MTA with the addition of 10% water-soluble chitosan group had the lowest biofilm viability value of E. faecalis, followed by MTA with the addition of 5% water soluble chitosan, and MTA.
Conclusion: The addition of water-soluble chitosan in various concentrations to MTA increased the antibiofilm ability against E. faecalis.  MTA with the addition of 10% water soluble chitosan produced the highest antibiofilm ability against E. faecalis significantly compared to MTA and MTA with the addition of 5% water-soluble chitosan."

"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."

Kemudian dilakukan evaluasi efek antimikroba dengan uji hitung koloni dan nilai viabilitas dengan metode MTT Assay. Hasil: Terdapat perbedaan bermakna jumlah koloni dan nilai viabilitas biofilm E. faecalis (p<0,05) dan biofilm C. albicans (p<0,05) antara seluruh konsentrasi larutan cuka apel, kontrol positif, dan kontrol negatif, dengan efek antimikroba larutan cuka apel tertinggi pada konsentrasi 2,5% dan terendah pada konsentrasi 0,63%. Kesimpulan: Larutan cuka apel 2,5% memiliki kemampuan antimikroba dengan nilai viabilitas dan jumlah koloni hampir sebanding dengan kontrol positif NaOCl 2,5%, sehingga larutan cuka apel dapat dipertimbangkan untuk dijadikan alternatif larutan irigasi saluran akar.

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."
