"Penelitian ini bertujuan untuk mengetahui pengaruh ketebalan resin terhadap depth of cure resin komposit serat sebagai substruktur. Lima belas spesimen dibagi menjadi 3 kelompok ketebalan berbeda: 3, 4, dan 5 mm n=5 . Masing-masing spesimen disinari dengan iradiansi 800 mW/cm selama 20 detik. Hasil penelitian menunjukkan depth of cure kelompok 1 adalah 81 , kelompok 2 adalah 78 dan kelompok 3 adalah 34. Nilai tersebut berbeda bermakna secara statistik melalui uji One-way ANOVA dan Post-hoc. Games-Howell. Disimpulkan bahwa ketebalan mempengaruhi depth of cure resin komposit serat sebagai substruktur.

The aim of this study is to know the effect of resin thickness on the depth of cure of fiber reinforced resin composite as substructure. Fifteen specimens are divided into 3 different thickness groups 3, 4, and 5 mm n 5 . Each specimen was cured with irradiation of 800 mW cm for 20 seconds. The result showed the depth of cure of group 1 was 81 , group 2 78 and group 3 34. The result was significantly different using One way ANOVA and Games Howell Post hoc test. It was concluded that resin thickness has effect on the depth of cure of fiber reinforced resin composit as substructure."

"Penelitian ini bertujuan untuk mengetahui pengaruh post-cure terhadap depth of cure DOC resin komposit serat dan membandingkan metode pengukuran DOC. Sembilan spesimen EverX Posterior warna A3 yang disinar dengan irradiansi 800-1000 mW/cm2 20 detik dibagi menjadi 3 kelompok: diukur setelah penyinaran dan setelah 24 jam post-cure dengan profil kekerasan Vickers; serta metode ISO 4049. DOC yang diukur setelah penyinaran dan setelah 24 jam post-cure 3,02 0,02 mm dan 3,93 0,03 mm; serta metode pengukuran ISO 4049 4,88 0,13 mm. Disimpulkan terdapat peningkatan bermakna DOC yang diukur setelah 24 jam post-cure, dan metode ISO 4049 menghasilkan DOC bermakna lebih tinggi dari profil kekerasan Vickers.

This study aims to identify the effect of post cure towards depth of cure DOC fiber reinforced composite and compare DOC measuring methods. Nine speciments of EverX Posterior shade A3 cured with light irradiation 800 1000 mW cm2 20s divided into 3 groups measured after curing and after 24 hours post cure with Vickers microhardness profile and ISO 4049 method. DOC that measured after curing and after 24 hours post cure are 3,02 0,02 mm and 3,93 0,03 mm and with ISO 4049 method 4,88 0,13 mm. It was concluded thatDOC measured after 24 hours post cure is significantly higher than immediately after curing, and ISO 4049 method produce significantly higher DOC than Vickers microhardness profile."

"Penelitian ini bertujuan untuk mengetahui kekuatan rekat geser resin komposit serat sebagai substuktur dengan resin komposit partikulat berbeda komposisi. Resin komposit partikulat G-aenial posterior Kelompok A, 10 spesimen dan Tetric N-ceram Kelompok B,10 spesimen digunakan sebagai lapisan atas resin komposit serat EverX Posterior. Uji kuat rekat geser dilakukan menggunakan UTM dengan beban 100 kgf dan crosshead-speed 0.5 mm/menit. Data dianalisis menggunakan uji statistik independent sample t test. Hasil penelitian menunjukan nilai rerata kuat rekat geser yakni 18,64 1.5 MPa A dan 22,05 1,8 MPa B . Disimpulkan bahwa terdapat perbedaan kuat rekat geser yang bermakna pada kedua kelompok.

The aim of this study was to identify shear bond strength fiber reinforced composite as a substructure with different composition of particulate filled composite. Particulate filled composite G aenial posterior Groups A, 10 specimen and Tetric N ceram Groups B, 10 specimen used as an upper layer of FRC EverX Posterior. Shear bond strength test was performed using UTM with a load of 100 kgf and crosshead speed of 0.5 mm min. Data were analyzed using statistical test independent sample t test. The result of this study showed the mean shear bond strength values are 18,64 1.5 MPa A and 22,05 1,8 MPa B . It was concluded that there is a significance difference of shear bond strength between two groups."

"Penelitian ini bertujuan untuk menganalisis pengaruh jarak penyinaran terhadap depth of cure DOC resin komposit serat sebagai substruktur. Delapan belas spesimen EverX Posterior warna A3 berbentuk silinder diameter 6 mm dan tebal 4 mm dibagi menjadi 3 kelompok jarak penyinaran 0, 2, dan 4 mm yang dipolimerisasi dengan LED Litex 695, irradiansi 800 mW/cm2, selama 20 detik. Pengukuran DOC dilakukan melalui rasio kekerasan Vickers. Analisis data dilakukan menggunakan uji ANOVA satu arah. Hasil penelitian menunjukkan DOC pada jarak penyinaran 0, 2, dan 4 mm sebesar 79 0,7, 77 0,6, dan 75 0,8. Disimpulkan terdapat perbedaan bermakna pada nilai DOC pada seluruh jarak penyinaran.

This study aims to analyze the effect of light curing distance on the depth of cure DOC of fiber reinforced composite as substructure. Eighteen specimens consist of EverX Posterior shade A3, formed into a cylindrical shape 6 mm in diameter and 4 mm thickness divided into 3 groups according to light curing distance 0, 2, and 4 mm which were polymerized with LED Litex 695, irradiance 800 mW cm2, for 20s. Meansurement of DOC was carried out by Vickers hardness ratio of specimens. Data were analyzed statistically by one way ANOVA test. The result showed the DOC at a light curing distances of 0, 2, and 4 mm was 79 0,7, 77 0,6, and 75 0,8. It was concluded that there is a significant difference in DOC among the light curing distance."
