SUMMARY Objective To evaluate polymerization shrinkage and depth of cure of two bulk fill flowable composites, one nanohybrid composite modified to a flowable consistency, and one standard flowable composite, comparing the scraping method to the Knoop hardness test. Methods Two bulk fill flowable composites, SureFil SDR flow (SSF) (Dentsply) and Venus Bulk Fill (VBF) (Heraeus Kulzer), one standard flowable, Filtek Supreme Ultra Flowable (FSUF) (3M/ESPE) (control), and one regular bulk composite that can be made flowable, SonicFill (SF) (Kerr), were used in this study. For polymerization shrinkage (PS), ten 2-mm samples were made for each composite and cured for 20 seconds and shrinkage was measured with a Kaman linometer. For hardness, ten specimens of each composite were made in a 10 × 10-mm mold and cured for 20 seconds; the bottom surface was scraped according to ISO 4049 specification, and the remaining thickness was measured with a micrometer. Hardness samples were prepared at 2-, 3-, 4-, and 5-mm thick ×14-mm diameter, cured for 20 seconds, and polished. After 24 hours of dry storage, a Knoop indenter was applied at 100 g load for 11 seconds. Three readings were made on the top and bottom of each specimen and averaged for each surface to calculate a Knoop hardness value and a bottom/top hardness ratio. One-way analysis of variance and Tukey tests were used to determine significant differences between thicknesses and between test methods for each material. Results PS values were 3.43 ± 0.51%, 3.57 ± 0.63%, 4.4 ± 0.79%, and 1.76 ± 0.53% for FSUF, SSF, VBF, and SF, respectively. VBF showed significantly greater shrinkage (4.4 ± 0.79%), followed by FSUF (3.43 ± 0.51%) and SSF (3.57 ± 0.63%), which were similar, and SF (1.76 ± 0.53%), which had significantly less shrinkage (p<0.05). Values for the scraping method for depth of cure were significantly greater for SSF and VBF (>5.0 mm), followed by SF (3.46 ± 0.16 mm) and FSU (2.98 ± 0.22 mm). Knoop top hardness values (KHN) were: VBF 21.55 ± 2.39, FSUF 44.62 ± 1.93, SSF 29.17 ± 0.76, and SF 72.56 ± 2.4 at 2 mm and were not significantly different at 3-, 4-, and 5-mm thick within each material. Ratios for bottom/top values (depth of cure) for 2, 3, 4, and 5 mm were: VBF 0.80 ± 0.1, 0.78 ± 0.03, 0.67 ± 0.10, and 0.59 ± 0.07, respectively; SSF 0.74 ± 0.08, 0.72 ± 0.08, 0.69 ± 0.18, and 0.62 ± 0.08, respectively; SF 0.82 ± 0.05, 0.68 ± 0.05, 0.47 ± 0.04, and 0.21 ± 0.02, respectively; and FSUF 0.56 ± 0.08 at 2 mm and 0.40 ± 0.08 at 3 mm. The bottom/top ratio was .80 or less at all depths and decreased below 0.70 at 4-mm depth for VBF and SSF, at 3 mm for SF and at 2 mm for FSUF.

Latar Belakang. Resin komposit merupakan bahan pilihan untuk reparasi Gigi Tiruan Cekat porcelain fused to metal (PFM) Karena estetis baik dan manipulasi mudah. Tujuan penelitian ini adalah mengetahui perbedaan kekuatan geser perlekatan resin komposit pada permukaan logam Gigi Tiruan Cekat dengan menggunakan resin komposit jenis packable dan jenis flowable. Metode penelitian. Subjek penelitian berupa logam NiCr (Noritake, Japan) berbentuk silinder dengan diameter 10 mm dan tinggi 3 mm. Penelitian dibagi menjadi dua kelompok, masing-masing terdiri dari 10 subjek. Kelompok pertama reparasi dengan resin komposit packable (Z250™ 3M ESPE, USA) dan kelompok kedua reparasi dengan resin komposit flowable (Dyad flow, Kerr, USA). Permukaan subjek dikasari dengan wheel diamond bur, dietsa dengan asam fosfat 37 % (Scotchbond™, 3M ESPE, USA) kemudian dicuci dan dikeringkan, selanjutnya diaplikasikan silan (Rely X™ Ceramic Primer, 3M ESPE, USA) dan bonding (Adper™ Single Bond, 3M ESPE, USA). Permukaan kemudian dilapisi dengan resin komposit packable dan flowable, disinari selama 40 detik. Subjek penelitian direndam di dalam distilled water dan dimasukkan ke dalam incubator dengan suhu 37°C selama 7 hari. Uji kekuatan geser dilakukan dengan menggunakan Universal Testing Machine. Data dianalisis dengan uji t. hasil uji t menunjukkan terdapat perbedaan bermakna kekuatan geser reparasi gigi tiruan cekat pada permukaan logam (p<0,05). Kesimpulan penelitian ini adalah kekuatan geser reparasi pada permukaan logam dengan menggunakan resin komposit flowable yang mengandung bahan coupling agent lebih tinggi dibandingkan reparasi pada permukaan porselen dengan menggunakan resin komposit packable. Background. One of selected material by repairing the fixed partial denture was composite resin because of its good aesthetics and low manipulation. The aim. This research was aimed at identifying the differences of shear bond strength of composite resin on metal surface by using different composite resins, namely packable and flowable composite resins. Method. The research subjects were cylinders with 10 mm in diameter and 3 mm in height. The research subjects with metal material of NiCr (Noritke, Japan) involved two groups. The first group comprising 10 repair subjects with composite packable (Z250™, 3M ESPE, USA) and 10 repair subjects with flowable composite (Dyad flow, Kerr, USA). The surface of the subjects were roughned with wheel diamond bur and etched with 37% phosphate acid (Scotbond™, 3M ESPE, USA) were applied. The surface was then coated with packable and flowable composite resins and light-cured for 40 seconds. The research subjects were immersed in distilled water and put into the incubator at temperature of 37°C for 7 days. The shear bond strength test was conducted using the Universal Testing Machine. Data were analyzed using t-test. The result. The research result showed that there were differences of shear bond strength of repair between packable and flowable composite resins. The result of t-test indicated significant diffrences on metal surface (p<0,05). The conclusion of this research is that shear bond strength of repair with flowable composite which contain coupling agent has higher shear bond strength than that of packable composite resin.
