Resin semen konvensional yang berhubungan dengan teknik total etch dikaitkan dengan insidensi sensitivitas post-operative pada sementasi restorasi indirek. Sebaliknya, resin semen self-adhesive lebih sedikit menyebabkan sensitivitas post-operative terhadap rangsangan dingin. Penelitian ini bertujuan untuk mengetahui perbedaan kebocoran mikro resin semen self-adhesive dengan resin semen konvensional pada sementasi inlei klas I resin komposit Subjek penelitian sepuluh gigi premolar dibagi menjadi dua kelompok perlakuan yaitu kelompok I untuk sementasi inlei kelas I resin komposit menggunakan resin semen self-adhesive, serta kelompok II, yang disementasi dengan resin semen konvensional. Subjek penelitian disimpan dalam saliva buatan selama 24 jam dalam inkubator suhu 37ºC, dilakukan thermocycling masingmasing suhu 60ºC dan 4ºC setiap 1 menit dan diulang sebanyak 25 kali. Tes kebocoran mikro dilakukan dengan cara subjek penelitian direndam dalam larutan biru metilen 2% di dalam inkubator suhu 37ºC selama 24 jam kemudian disentrifus kecepatan 3000 rpm selama 5 menit. Subjek penelitian dibelah menjadi dua bagian dengan separating disc secara vertikal arah mesiodistal, hasil belahan diamati dibawah mikroskop stereo perbesaran 250 kali. Penilaian dengan cara skor kebocoran mikro 0-3. Analisis data dengan uji U-Mann Whitney. Hasil penelitian menunjukkan tidak terdapat perbedaan kebocoran mikro restorasi inlei resin komposit menggunakan resin semen dual cure yang berbeda. Kesimpulan penelitian ini tidak terdapat perbedaan kebocoran mikro restorasi inlei resin komposit menggunakan resin semen dual cure yang berbeda.

Conventional resin cement which associated with total etch technique linked with the incidence of post operative sensitivity on cementation of indirect restoration. Conversely, self-adhesive resin cement caused less incidence of post operative sensitivity toward cold stimulation. The aim of this study was investigating the difference of microleakage between self-adhesive and conventional resin cement on cementation of class I composite resin inlay cementation. Ten human extracted premolar teeth were randomly divided into two groups, group I, for cementation class I composite resin inlay using self-adhesive resin cement, then group II for cementation using conventional resin cement. Specimens were stored in artificial saliva for 24 hours at 37ºC incubator, thermocycled at 60ºC and 4ºC each for 1 minute dan repeated 25 times then immersed in 2% methylene blue dye for 24 hours at 37ºC incubator and centrifuged for 5 minutes at 3000 rpm. Specimens cut into two pieces with separating disc vertically in mesiodistal direction, and dye penetration was assessed using stereo microscope 250 magnification according to 0-3 scoring point. Data was analyzed using U-Mann Whitney tests at ≤0.05 significance level and 95% confidence level. The results of the study showed that there was no difference of microleakage of composite resin inlay restoration using different dual cure resin cement. The conclusion of the study that there was no difference of microleakage of composite resin inlay restoration using different dual cure resin cement.
