Changes in the Surface Roughness of Glass Ionomer Cement and Zirconomer after Immersion in Carbonated Beverages

Abstract

Nano glass ionomer cement (GIC) with nano zirconia as a raw material called zirconium is a newly developed type of restoration/tooth filling material that is used in dentistry. Objective: To examine the effect of carbonated beverages on the surface roughness of Zirconomer and GIC filling materials and determine if there was any difference between them. Methods: This is a true-experimental laboratory research study with a pre-posttest group design. The research samples consisted of 32 samples, 16 GIC samples and 16 Zirconomer samples, further divided into four time-sensitive groups: day 1, day 3, day 5, and day 7. The samples were immersed in artificial saliva and carbonated beverages for 24 hours. Surface roughness was measured using a surface roughness tester. Results: The average surface roughness from day 1 to day 7 of the GIC material immersed in carbonated beverages was 4.17 μm, which is higher than the average surface roughness of Zirconomer (3.091 μm), and the difference was significantly different (pConclusion: Zirconomer was found to be more resistant to carbonated beverages than GIC. There was a positive correlation between the length of immersion time in the carbonated beverages and the surface roughness of GIC and Zirconomer.

Conventional and Resin-Modified Glass Ionomer Cement Surface Characteristics after Acidic Challenges

“…The behavior of materials in acid challenges depends on the chemical structure. Previous studies have also shown a tendency of surface degradation when these materials were exposed to acidic and alcoholic beverages action [ 38 , 39 , 40 ]. The consumption of soft drinks over a long period of time can induce erosive wear of restorative materials [ 41 , 42 , 43 ].…”

The Effect of 1% Povidone Iodine Mouthwash on The Surface Roughness of Zirconia Reinforced Glass Ionomer Cement

“…6,7 Semen ionomer kaca diperkuat zirkonia merupakan modifikasi dari bahan restorasi semen ionomer kaca dengan penambahan partikel nano zirkornia berukuran 1-100 nm. 8 Penambahan partikel zirkonia dapat meningkatkan sifat mekanis sehingga menghasilkan bahan restorasi yang memiliki kekuatan setara amalgam dengan daya tahan material dan toleransi terhadap beban oklusal yang lebih baik. Semen ionomer kaca diperkuat zirconia tetap mempertahankan kemampuannya dalam melepaskan flourida seperti semen ionomer kaca konvensional.…”

“…11 Peningkatan kekasaran permukaan akan menjadi faktor predisposisi dari perlekatan bakteri dan plak yang berpotensi meningkatkan resiko kerusakan tumpatan, perubahan warna, perkembangan karies gigi, dan penyakit periodontal. 8,9 Kekasaran permukaan terjadi karena adanya perubahan kondisi lingkungan di dalam rongga mulut. 12 Perubahan kondisi tersebut dapat disebabkan karena paparan faktor eksternal seperti penggunaan obat kumur.…”
