Latar Belakang: Kemampuan adhesi siler terhadap dentin merupakan faktor penting dalam kesuksesan perawatan endodontik. Siler resin epoksi sebagai gold standart memiliki kemampuan adhesi yang superior, tetapi tidak memiliki sifat bioaktif sehingga berkembang siler kalsium silikat. Tujuan: Membandingkan kekuatan push-out bond strength dan failure mode siler AH PlusŪ Bioceramic dan Ceraseal dengan siler AH PlusŪ. Metode: Tiga puluh gigi premolar dibagi menjadi tiga kelompok untuk preparasi dan pengisian saluran akar menggunakan siler AH PlusŪ Bioceramic (kelompok 1), Ceraseal (kelompok 2) dan siler AH PlusŪ (kelompok 3). Sampel diinkubasi selama tujuh hari pada suhu 37oC, kemudian dipotong pada area sepertiga apikal dan medial. Nilai push-out bond strength dan failure mode dianalisis. Hasil: AH PlusŪ Bioceramic memiliki perbedaan nilai push-out bond strength dan failure mode yang signifikan dibanding AH PlusŪ dan Ceraseal. Ceraseal dan AH PlusŪ tidak memiliki perbedaan nilai secara signifikan. Analisis gambaran failure mode oleh dua orang observer menunjukkan reliabilitas data yang tinggi. AH PlusŪ Bioceramic memiliki dominasi kegagalan campuran, sedangkan Ceraseal dan AH PlusŪ memiliki persentasi kegagalan campuran dan kohesif yang seimbang. Kesimpulan: Seluruh kelompok siler menunjukkan kemampuan adhesi yang baik terhadap permukaan dentin, meskipun nilai push-out bond strength siler AH PlusŪ Bioceramic paling rendah diantara seluruh kelompok.
......Background: The adhesion of sealers to dentin is important for successful endodontic treatment. As the gold standard, epoxy resin sealers have superior adhesion, but lack bioactive properties, hence the development of calcium silicate sealers. Objective: To compare the push-out bond strength and failure mode of AH PlusŪ Bioceramic and Ceraseal sealers with AH PlusŪ Sealer. Methods: Thirty premolars were divided into three groups for root canal preparation and obturation with AH PlusŪ Bioceramic (group 1), Ceraseal (group 2), and AH PlusŪ (group 3). The samples were incubated at 37°C for seven days, then cut at the apical and medial third. Push-out bond strength and failure mode were analyzed. Results: AH PlusŪ Bioceramic demonstrated significant differences in push-out bond strength and failure mode values compared to AH PlusŪ and Ceraseal. Ceraseal and AH PlusŪ were not significantly different. Analysis of failure mode descriptions by two observers showed high data reliability. AH PlusŪ Bioceramic had a predominance of mixed failures, whereas Ceraseal and AH PlusŪ had equal percentages of mixed and cohesive failures. Conclusion: All sealer groups showed good adhesion to the dentin surface, although the push-out bond strength value of AH PlusŪ Bioceramic sealer was the lowest among the groups.
