"ABSTRAK Latar Belakang: siler polidimetilsiloksan merupakan siler baru yang berpotensi menutup saluran akar lebih baik. Tujuan: membandingkan tingkat kerapatanpengisian di sepertiga apeks antara teknik kon tunggal (KT) dan downpackbackfill(DB) menggunakan siler polidimetilsiloksan. Metode: empat puluh gigipremolar bawah dibagi menjadi dua kelompok KT dan DB. Setelah pengisiansaluran akar, sampel diinkubasi, dilapisi cat kuku, direndam dalam tinta India, laludibuat transparan dengan metode Robertson. Kebocoran di sepertiga apeksdievaluasi dengan mikroskop stereo. Hasil: skor kebocoran terendah (0-0,5 mm)dimiliki oleh kelompok KT dan skor kebocoran tertinggi (>1 mm) dimiliki olehkelompok DB. Kesimpulan: teknik kon tunggal memberikan tingkat kerapatanyang lebih baik dibandingkan downpack-backfill, walaupun secara statistik perbedaan antar keduanya tidak signifikan. ABSTRACT Background: polydimethylsiloxane sealer is a brand new sealer that potentiallyhas a better sealing ability to the root canal. Aim: to compare the apical sealingability in one third apex between single cone (SC) and downpack-backfill (DB)technique using polydimethylsiloxane sealer. Methods: fourty extracted humanmanibular premolars devided into two group, SC and DB. After obturated withpolydimethylsiloxane sealer, samples were stored in incubator, coated with nailvarnish, immersed in India ink, and then specimens were cleared usingRobertson?s technique. The apical dye penetration was evaluated using astereomicroscope. Result: the lowest leakage score (0-0,5 mm) was found in SCgroup and the highest score(>1 mm) in DB group. Summary: single conetechnique exibited better sealing ability rather than downpack-backfill technique, although no statistical significant difference between this two techniques. ;Background: polydimethylsiloxane sealer is a brand new sealer that potentiallyhas a better sealing ability to the root canal.

"ABSTRAKLatar Belakang: Penggunaan gutaperca yang dipanaskan menghasilkan adaptasiyang baik dan material obturasi yang homogen. Teknik kompaksi lateral panasmenggabungkan kon gutaperca utama dan aksesoris menjadi satu massa homogenyang solid. Teknik carrier-based gutta-percha memiliki seal dan adaptasi yangbaik. Teknik downpack-backfill mengkombinasikan teknik kompaksi vertikal daninjeksi termoplastis. Tujuan: Membandingkan adaptasi tepi sepertiga apikalapeks antara teknik kompaksi lateral panas, carrier-based gutta-percha, dandownpack-backfill. Metode: Preparasi saluran akar pada 90 gigi saluran akartunggal dan dibagi menjadi tiga kelompok, yaitu kompaksi lateral panas (KLP),carrier-based gutta-percha (T), dan downpack-backfill (DB). Adaptasi tepisepertiga apikal apeks ditentukan dengan melihat penetrasi pewarna di antaramaterial obturasi dan dinding dentin pada sampel yang dipotong melintang. Hasil:Adaptasi tepi sepertiga apikal apeks DB paling baik, diikuti T dan KLP (p>0,05).Kesimpulan: Adaptasi tepi sepertiga apikal apeks teknik downpack-backfillpaling baik, namun tidak berbeda bermakna.

ABSTRACTBackground: The use of heated gutta-percha can provide good adaptation andhomogeneity of obturation material. Warm lateral compaction techniquecombines primary and accessory gutta-percha cones into one solid homogeneousmass. Carrier-based gutta-percha technique has a good adaptation and sealingability. Downpack-backfill technique combines warm vertical compaction andthermoplastic injection techniques. Aim: Compare the apical third marginaladaptation of warm lateral compaction, carrier-based gutta-percha, anddownpack-backfill techniques. Methods: Ninety single rooted teeth were preparedand assigned to three groups: warm lateral compaction (KLP), carrier-basedgutta-percha (T), and downpack-backfill (DB). Apical third marginal adaptationwas evaluated by observing the dye penetration between the obturation materialand the root canal walls on cross sectioned samples. Results: DB showed the bestapical third marginal adaptation, followed by T and KLP (p>0,05). Conclusion:Downpack-backfill technique has the best apical third marginal adaptation, butno significant difference was observed between the three techniques."
