"Latar Belakang. Kebocoran mikro masih menjadi masalah utama dalam bidang kedokteran gigi karena dapat menyebabkan bakteri dan cairan mulut masuk diantara dinding kavitas dan tumpatan. Tujuan. Mengevaluasi kebocoran mikro pada tumpatan GIC Konvensionaldan RMGIC.Metode. Gigi premolar dipreparasi pada bagian oklusal dengan ukuran 3 x 3 x 2,5 mm, kemudian ditumpat dengan GIC Fuji IX, Fuji II dan Fuji II LC. Kemudian, spesimen direndam dalam akuabides, setelah 24 jam direndam dalam larutan pewarna methylene blue 1%, kemudian dipotong melintang arah bukolingual dan diamati di bawah stereomikroskop.Hasil Penelitian. Kebocoran mikro paling besar terjadi pada GIC Fuji IX, diikuti dengan Fuji II dan Fuji II LC.Kesimpulan. Terdapat kebocoran mikro pada tumpatan GIC Konvensional dan RMGIC, dimana derajat kebocoran mikro pada GIC Konvensional lebih besar dibandingkan RMGIC.

Background. Microleakage around restoration is still a major problem in clinical dentistry, which can cause the penetration of bacteria and oral fluids between the cavity wall and the restoration. Objectives. To evaluate the microleakage of Conventional GIC and RMGIC restoration.Methods. The premolars were prepared oclusally to a size of 3 x 3 x 2,5 mm dimensions, and were filled with GIC Fuji IX, Fuji II, and Fuji II LC. Then, all specimens were stored in aquabidest, after 24 hours all specimens were immersed in 1 % methylene blue dye, then were sectioned in a buccolingual direction, and inspected under stereomicroscope.Results. GIC Fuji IX showed maximum leakage followed by Fuji II and Fuji II LC.Conclusions. The microleakage was evident in Conventional GIC and RMGIC restoration, where the microleakage degree in Conventional GIC were greater than RMGIC."

"ABSTRAK Latar Belakang: Berbagai material kaping pulpa berbahan dasar kalsium silikatterus dikembangkan, diantaranya semen berbasis kalsium silikat denganpenambahan steroid. Tujuan: Menganalisis efek penambahan steroid pada semenberbasis kalsium silikat terhadap viabilitas sel fibroblas. Metode: Sel fibroblasembrio ayam direndam dalam ekstrak larutan semen berbasis kalsium silikatdengan penambahan steroid dan MTA. Viabilitas sel dihitung dengan menggunakan uji MTT. Hasil: Terdapat perbedaan bermakna (p ≤ 0,05)viabilitas sel pada kelompok semen berbasis kalsium silikat dengan penambahansteroid dibandingkan kelompok kontrol dan MTA. Kesimpulan: Penambahansteroid menurunkan viabilitas sel. Terdapat peningkatan pada 72 jam, yang menandakan terjadinya proliferasi sel.ABSTRACT Background: Calcium silicate based materials are being developed continuously,one of them is calcium silicate based cement containing steroid. Objective: Toanalyze the effect of steroid addition in calcium silicate based cement onfibroblast cells viability. Methods: Chicken embryonic fibroblast cells wereimmersed in extract solution of calcium silicate based cement containing steroidand MTA. Viability was analyzed by MTT Assay. Results: Significant difference (p ≤ 0,05) of viability on calcium silicate based cement containing steroid groupwas found, compared to control and MTA group. Conclusion: Steroid additiondecrease viability. There was an increase in 72 hours, marking cells proliferation.;Background: Calcium silicate based materials are being developed continuously,one of them is calcium silicate based cement containing steroid.
