[Latar Belakang: Kebocoran mikro dipengaruhi oleh jenis semen saluran akar.Tujuan: menganalisis tingkat kebocoran mikro pengisian saluran akarmenggunakan semen resin epoksi (SRE) dan Mineral Trioxide Aggregate(SMTA). Metode: Tiga puluh dua gigi premolar bawah, dibagi dua kelompoksama besar, yaitu kelompok SRE dan SMTA. Setelah pengisian saluran akar,sampel diinkubasi (370C, 24 jam), kemudian direndam dalam tinta India selama 7X 24 jam. Sampel didekalsifikasi sampai dengan transparan. Kedalaman penetrasitinta dievaluasi dengan mikroskop stereo. Skor 1 untuk penetrasi tinta 0-0,5 mm,skor 2 untuk penetrasi tinta 0,51-1 mm, dan skor 3 untuk penetrasi tinta >1 mm.Hasil: Distribusi proporsi kebocoran terbesar kelompok SRE terdapat pada skor1, yaitu sebesar 37,5%. Sedangkan distribusi proporsi kebocoran terbesarkelompok SMTA terdapat pada skor 1, yaitu sebesar 21,9%. Tidak terdapatperbedaan bermakna antara kelompok SRE dan SMTA. Kesimpulan: Semenresin epoksi dan semen MTA memiliki tingkat kebocoran yang sama., Background: The microleakage affected by type of root canal sealer. Purpose: toanalyze the microleakage of obturation using epoxy resin-based (SRE) andmineral trioxide aggregate-based (SMTA) as root canal sealer. Methods: Thirtytwo mandibular first premolars were equally divided into two groups. They wereSRE group and SMTA group. After obturation, the specimens were incubated(370C, 24 h), immersed in Indian ink for 7 days, decalcified, dehydrated, andmade transparent. Dye penetration were evaluated under stereomicroscope andgiven score 1-3. Specimen with 0-0,5 mm dye penetration was given score 1,while 0,51-1 mm penetration was given score 2, and > 1 mm was given score 3.The results were statistically analyzed with Kolmogorov Smirnov test. Results:The largest proportion distribution in SMTA group was score 1 (37,5%), whilstthe largest proportion distribution in SMTA group was score 1 (21,9%). Therewas no significant difference between the microleakage of epoxy resin-based andmineral trioxide aggregate-based sealer, observed from the one-third apicalleakage. Conclusion: The microleakage of mineral trioxide aggregate basedsealer and epoxy resin-based sealer was relatively similar.] |
