Tujuan penelitian ini adalah untuk mengetahui kebocoran mikro pada orifis barier semen ionomer kaca modifikasi resin (IKMR), semen ionomer kaca modifikasi resin nano (IKMRn) dan resin komposit core build up. Pada penelitian ini digunakan 30 gigi premolar mandibula pasca ektraksi yang dibagi menjadi 3 kelompok masing-masing terdiri dari 10 gigi dan 10 gigi untuk kelompok kontrol yang dibagi menjadi 5 gigi kontrol positif dan 5 gigi kontrol negatif. Untuk kelompok kontrol tidak diaplikasikan bahan orifis barier. Semua gigi dipreparasi dengan teknik Crown Down, dan diobturasi dengan guta perca protaper dan siler resin. Setelah siler mengeras, guta perca sedalam 4 mm diambil dari orifis saluran akar kemudian kelompok I diaplikasikan bahan orifis barier IKMR, kelompok II diaplikasikan IKMRn dan kelompok III diapikasikan resin komposit core build up. Seluruh subjek penelitian dilakukan thermocycling dengan temperatur 5° dan 55° masing-masing 30 detik sebanyak 500 kali, kemudian direndam dalam larutan metilen biru selama 5 hari dan selanjutnya gigi dibelah dengan arah mesiodistal. Pengamatan kebocoran mikro diamati dengan stereomikroskop dengan perbesaran 60x. Hasil ANAVA satu jalur menunjukkan bahwa terdapat pengaruh orifis barier IKMR, IKMRn dan resin komposit core build up terhadap kebocoran mikro pada gigi pasca perawatan saluran akar. Hasil LSD menunjukkan bahwa terdapat perbedaan kebocoran mikro yang bermakna antara orifis barier IKMR dengan IKMRn dan IKMR dengan resin komposit core build up (p<0,05), serta tidak terdapat perbedaan kebocoran mikro antara orifis barier IKMRn dengan resin komposit core build up (p>0,05). Pada penelitian ini, disimpulkan bahwa ada pengaruh antara orifis barier barier IKMR, IKMRn dan resin komposit core build up terhadap kebocoran mikro pada gigi pasca perawatan saluran akar.

The purpose of this study was to investigate the microleakage in orifice barrier resin modified glass ionomer, resin modified glass ionomer nano and resin composite core build up. This study was used 30 extracted humand mandibullary premolars were divided into 3 groups each consisting of 10 teeth, and 10 teeth for the control group which is divided into 5 teeth for positive control and five teeth for negative control. For the control group did not apply orifice barrier material. All teeth were prepared with the Crown Down technique, and were obturated using Protaper guta perca and resin sealer. After sealer set, about 4mm of gutta percha was removed from root canal orifice and then group I was applied orifice barrier material resin modified glass ionomer, group II was applied resin modifiefd glass ionomer nano and group III was applied resin composite core build up, for positive and negative control groups did not apply orifice barrier materials. All the subject of the research were thermocycled for 500 cycles at temperature 5 ° and 55 ° for 30 seconds, then immersed in a methylene blue for 5 days and after that all te subject were sectioned in a mesiodistal direction. Microleakage was measured with microscope stereo with 60x magnification. ANAVA results showed that orifice barier materials resin modified glass ionomer, resin modifiefd glass ionomer nano and resin composite core build up influenced the microleakage of the tooth after root canal treatment. LSD results showed that there were significant differences in microleakage between the orifice barrier resin modified glass ionomer and resin modified glass ionomer nano, and also resin modified glass ionomer nano with resin composite core build up (p <0.05), and there were no difference between the orifice barrier resin modified glass ionomer nano with resin composite core build up (p > 0.05). In this study, it was concluded that aplication of orifice barrier resin modified glass ionomer cement, resin modified glass ionomer cement nano and resin composite core build up influenced the microleakage of the tooth after root canal treatment.
