Latar belakang: Siler dapat meningkatkan sealing ability Tujuan: Menganalisis dan membandingkan sealing ability pengisian saluran akar dengan siler bioceramic dan resin metakrilat. Metode: Tiga puluh gigi dengan saluran akar tunggal, dipreparasi dengan ProTaper Next, dibagi dalam dua kelompok secara acak; Masing-masing grup diisi dengan gutaperca berlapis, untuk kelompok 1 menggunakan Siler Bioceramic SB dan kelompok 2 Siler Resin-Metakrilat SRM . Pengukuran kebocoran dengan tinta india pada daerah sepertiga apikal apeks yang dipotong secara melintang, kemudian dilihat dengan mikroskop stereo. Hasil: Kelompok siler bioceramic menunjukkan celah tepi yang lebih sedikit jika dibandingkan dengan siler resin-metakrilat. Kesimpulan: Sealing ability pengisian saluran akar menggunakan siler bioceramic SB lebih baik dibandingkan dengan siler resin-metakrilat SRM .

ABSTRAK
Background Sealer may increase sealing ability. Purpose To compare and analyze sealability of obturation using the bioceramic sealer and methacrylate resin based sealer. Methods thirty single rooted teeth were prepared using ProTaper Next and divided randomly into two groups the first group was obturated with Bioceramic Sealer SB while the second group was obturated with methacrylate resin based sealer SRM . Each group used coated gutta percha as a core material. Apical third marginal adaptation was evaluated by observing the dye penetration between the obturation material and the root canal walls on cross sectioned samples. Results SB Showed the least microleakage in the apical third marginal adaptation, followed by SRM. Conclusion Obturation of root canal using bioceramic sealer has the best sealing ability at the apical third, compared to SRM.

Latar Belakang: E.faecalis isolat klinis merupakan bakteri yang menyebabkan lesi periapeks persisten. Bioceramic dan Mineral Trioxide Aggregate merupakan siler yang mempunyai sifat anti bakteri. Tujuan: Untuk menganalisis efek anti bakteri siler Bioceramic dan MTA terhadap E.faecalis isolat klinis pada waktu 2 menit segera , 4 jam initial setting , 1 dan 7 hari setelah pengadukan siler. Metode: Efek anti bakteri siler Bioceramic dan MTA diperiksa dengan direct contact test. Masing-masing siler dikontakkan langsung dengan E.faecalis isolat klinis 2 menit, 4 jam, 1 dan 7 hari setelah pengadukan siler. Suspensi ini dioleskan pada medium agar dan diinkubasi 24 jam untuk melihat koloni bakteri yang tumbuh CFU/ml. Hasil: Terdapat perbedaan bermakna antara siler Bioceramic dan MTA pada waktu 7 hari, antara siler Bioceramic pada waktu 2 dan 4 jam serta waktu 4 jam dan 7 hari setelah pengadukan siler. Kesimpulan: siler Bioceramic dan MTA mempunyai efek anti bakteri yang baik terhadap E.faecalis pada saat segera, initial setting, dan 1 hari setelah pengadukan siler, pada waktu 7 hari setelah pengadukan, siler MTA yang paling baik. Siler MTA mempunyai efek anti bakteri yang konstan sampai 7 hari Keywords : Entereococcus faecalis isolat klinis, Siler Bioceramic dan Mineral Trioxide Aggregate MTA ......Background: E.faecalis isolate clinic is a kind of bacteria that cause persistent periapical lesion. Bioceramic and Mineral Trioxide Aggregate are sealers that having antibacterial properties. Aim: To analyze antibacterial effect of Bioceramic and MTA sealers against E.faecalis isolate clinic at 2 minutes fresh , 4 hours initial setting , 1 day and 7 day after mixed the sealers. Methods: Antibacterial effect of Bioceramic and MTA sealers was assessed by direct test contact. Each sealer was contacted with E.faecalis isolate clinic at 2 minutes, 4 hours, 1 day and 7 days after mixed the sealers. This suspension was swab in agar medium and incubated for 24 hours. The colony in agar plates is counted with colony forming unit CFU . Result: The significant differences was shown by Bioceramic and MTA at 7 days, between Bioceramic at 2 minutes fresh and 4 hours initial setting also at 4 hours initial setting and 7 days after mixed the sealer. Conclusion: Both of Bioceramic and MTA sealers have a good antibacterial effect at fresh, initial setting and 1 hour after mixed the sealer but at 7 days, MTA was the greater. MTA sealer has a constant antibacterial effect until 7 days.
