ABSTRAKLatar Belakang: Penggunaan gutaperca yang dipanaskan menghasilkan adaptasi
yang baik dan material obturasi yang homogen. Teknik kompaksi lateral panas
menggabungkan kon gutaperca utama dan aksesoris menjadi satu massa homogen
yang solid. Teknik carrier-based gutta-percha memiliki seal dan adaptasi yang
baik. Teknik downpack-backfill mengkombinasikan teknik kompaksi vertikal dan
injeksi termoplastis. Tujuan: Membandingkan adaptasi tepi sepertiga apikal
apeks antara teknik kompaksi lateral panas, carrier-based gutta-percha, dan
downpack-backfill. Metode: Preparasi saluran akar pada 90 gigi saluran akar
tunggal dan dibagi menjadi tiga kelompok, yaitu kompaksi lateral panas (KLP),
carrier-based gutta-percha (T), dan downpack-backfill (DB). Adaptasi tepi
sepertiga apikal apeks ditentukan dengan melihat penetrasi pewarna di antara
material 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-backfill
paling baik, namun tidak berbeda bermakna.
ABSTRACTBackground: The use of heated gutta-percha can provide good adaptation and
homogeneity of obturation material. Warm lateral compaction technique
combines primary and accessory gutta-percha cones into one solid homogeneous
mass. Carrier-based gutta-percha technique has a good adaptation and sealing
ability. Downpack-backfill technique combines warm vertical compaction and
thermoplastic injection techniques. Aim: Compare the apical third marginal
adaptation of warm lateral compaction, carrier-based gutta-percha, and
downpack-backfill techniques. Methods: Ninety single rooted teeth were prepared
and assigned to three groups: warm lateral compaction (KLP), carrier-based
gutta-percha (T), and downpack-backfill (DB). 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: DB showed the best
apical third marginal adaptation, followed by T and KLP (p>0,05). Conclusion:
Downpack-backfill technique has the best apical third marginal adaptation, but
no significant difference was observed between the three techniques.
