Effect of Different Herbal Tea Preparations on the Color Stability of Glass Ionomer Cements

Abstract

Objective To compare the color stability of the newer glass ionomer cements (GIC) when exposed to “Green tea” (GT), “Tulsi tea” (TT), and “Areca tea” (AT) using spectrophotometric analysis. Materials and Methods We selected commercially available GC Fuji IX GP EXTRA and Ketac Universal for this study. Eighty disc-shaped samples were made using a mold, which were immersed in the freshly prepared test solutions (distilled water, GT, TT, and AT) for 15 minutes per day for 60 days. The color estimation was done using a spectrophotometer. Results GC Fuji IX samples had a significantly higher mean difference in ΔE value than Ketac Universal when immersed in GT, AT, and control (P<0.001, 0.018, and <0.001), respectively. With GC Fuji IX, GT and AT stained more than TT and control solutions. Samples of Ketac Universal showed a significantly higher mean difference in ΔE values when immersed in AT, followed by GT, TT, and control. Conclusion Within the study’s limitations, we conclude that both the GICs exhibited staining over time on exposure to all the test solutions. Ketac Universal demonstrated lower staining potential than GIC Fuji IX GP Extra for GT and AT.

Evaluasi Perubahan Warna Semen Ionomer Kaca dengan Penambahan Ekstrak Etanol Propolis Trigona spp.

“…3 Semen ionomer kaca merupakan bahan pilihan karena bersifat biokompatibel, mampu berikatan secara kimiawi dengan struktur gigi, memiliki kekuatan lentur yang baik, dan melepaskan fluor secara perlahan dalam periode waktu yang lama. 4,5 Secara in vitro, ion fluor ditemukan memiliki efek antikariogenik melalui penurunan demineralisasi dan peningkatan remineralisasi melalui konversi hidroksiapatit menjadi fluorapatit yang lebih tahan terhadap asam, dan dengan menghambat pembentukan dan metabolisme bakteri. 6,7 Akan tetapi, relevansi klinis restorasi yang melepaskan fluor masih diperdebatkan.…”

“…Di sisi lain, faktor eksternal dikaitkan dengan adsorpsi atau absorpsi dari bahan-bahan eksternal. 4 Penelitian ini memodifikasi komposisi kimiawi semen ionomer kaca (SIK) dengan menambahkan ekstrak etanol propolis (EEP). Manipulasi ini menyebabkan perubahan warna intrinsik dari bahan semen ionomer.…”

In Vitro Evaluation of Mechanical, Surface, and Optical Properties of Restorative Materials Applied with Different Techniques

“…A limited number of studies in the literature have evaluated various optical, surface, and mechanical properties of resin composite materials and high-viscosity GICs after placement using different techniques [12][13][14][15][16][17][18][19]. This study aimed to evaluate the effects of applying different techniques on the optical, surface, and mechanical properties of three different restorative materials, which have recently begun to be used frequently in clinics owing to their advantages, such as advanced chemical and mechanical properties and ease of application.…”
