L Latar Belakang : Material tumpatan gigi posterior terutama area proksimal (kelas 2) memerlukan kekuatan tarik diametral (DTS) yang baik untuk menahan gaya kunyah. Semen ionomer kaca (SIK) merupakan material tumpatan yang biomimetik, tetapi kekuatan mekaniknya kurang terutama bila terkontaminasi cairan saat tahap pengerasan. Semen ionomer kaca berteknologi glass hybrid dikatakan memiliki sifat mekanik yang lebih baik, namun sejumlah penelitian menunjukkan hasil pro dan kontra. Tujuan: Penelitian ini bertujuan untuk mengetahui dan menilai perbedaan pengaruh paparan air dan waktu terhadap kekuatan tarik diametral tumpatan semen ionomer kaca glass hybrid. Metode: Enam puluh sampel SIK glass hybrid (Equia Forte Fil) berbentuk silinder (6 x 3 mm) disiapkan. Sampel dibagi menjadi 2 kelompok besar, kelompok yang diberikan dan tidak diberikan paparan air sesaat setelah pengerasan awal. Masingmasing kelompok besar dibagi menjadi 3 subkelompok berdasarkan waktu perendaman dalam saliva buatan (1 jam, 1 hari, dan 1 bulan). Sampel disimpan dalam inkubator bersuhu 370C selama masa perendaman, kemudian dilakukan uji DTS dengan universal testing machine. Hasil: Berdasarkan statistik, nilai DTS SIK glass hybrid pasca perendaman dalam saliva buatan selama 1 hari lebih tinggi secara bermakna dibandingkan pasca perendaman 1 jam, baik pada sampel yang diberi paparan air sesaat setelah pengerasan awal maupun tidak (p<0,05). Nilai DTS sampel yang tidak diberi paparan air dan direndam dalam saliva buatan selama 1 bulan mengalami peningkatan dibandingkan 1 hari, walaupun tidak berbeda bermakna (p=0,93). Sebaliknya nilai DTS sampel yang diberi paparan air dan direndam dalam saliva buatan selama 1 bulan mengalami penurunan dibandingkan 1 hari, walaupun juga tidak bermakna (p=0,083). Perbedaan yang bermakna terlihat pada nilai DTS antara sampel yang diberikan paparan air sesaat setelah pengerasan awal dan tidak diberikan paparan air pasca perendaman 1 bulan (p=0,03), dengan sampel yang tidak terpapar air memiliki nilai DTS yang lebih tinggi. Kesimpulan : Paparan air sesaat setelah pengerasan awal dapat menurunkan DTS SIK glass hybrid dalam jangka panjang, yang akan berpengaruh terhadap ketahanan restorasi menahan gaya kunyah.
B Background : Proximal (Class 2) posterior dental restorative materials require good diametral tensile strength (DTS) to resist chewing forces. Glass ionomer cement (GIC) is a biomimetic restorative material, but it has poor mechanical strength, especially when contaminated with liquid during the setting stage. Glass ionomer cement with glass hybrid technology is said to have better mechanical properties, but a number of studies have shown pros and cons. Objectives : To determine and assess the difference in the effect of water exposure and time on the DTS of glass hybrid ionomer cement fillings. Methods : Sixty cylindrical (6 x 3 mm) glass hybrid ionomer cement (Equia Forte Fil) samples were prepared. Samples were divided into 2 large groups, a group that was given water exposure shortly after the initial setting, and a group that was not water exposured. Each group was divided into 3 subgroups based on immersion time in artificial saliva ( 1 hour, 1 day, and 1 month), describing the age of the cement. The samples were stored in an incubator at 370C during the immersion period, then the DTS tests were carried out using a universal testing machine. Results : Based on statistics, the DTS of glass hybrid ionomer cement after 1 day immersion in artificial saliva was significantly higher than after 1 hour of immersion, whether the samples exposed to water shortly after initial setting or not (p<0.05). The DTS value of samples that were not exposed to water shortly after the initial setting and immersed in artificial saliva for 1 month increased compared to which immersed for 1 day, although not significantly different (p=0.93). On the other hand, the DTS value of samples exposed to water shortly after the initial setting and immersed in artificial saliva for 1 month decreased compared to which immersed for 1 day, with no significant differences (p=0.083). A significant difference in DTS was seen between samples that were exposed to water shortly after the initial setting and were not water exposured after 1 month of immersion (p=0.03); samples that were not exposed to water had higher DTS value. Conclusions : Exposure to water shorly after initial setting can reduce the DTS of the glass hybid ionomer cement in the long term, which will affect the resilience of the restoration to resist chewing forces.
