Material restorasi idealnya selain harus mampu beradaptasi baik dengan kavitas, estetik, tidak mengiritasi, juga harus dapat berikatan baik dengan struktur gigi. Material restorasi Alkasite mulai dikembangkan tahun 2016 memiliki warna yang sama dengan gigi juga diklaim memiliki kekuatan mekanik yang lebih baik jika dibandingkan dengan Glass Ionomer Cement (GIC). Penelitian ini bertujuan untuk menganalisis interface antara material restorasi GIC dan Alkasite dengan struktur gigi menggunakan uji Scanning Electron Microscope (SEM) dan uji Energy Dispersive X-ray Spectroscopy (EDX) Mapping. Spesimen pada penelitian ini menggunakan gigi premolar rahang atas yang direstorasi dengan GIC dan Alkasite pada kavitas kelas V G.V Black dan disimpan di dalam inkubator selama 1 bulan dengan suhu 37°C. Spesimen dipotong secara longitudinal dari arah bukopalatal, kemudian dianalisis pada bagaian interface restorasi dengan menggunakan SEM dan EDX mapping merek Thermo Scientific Prisma E. Hasil SEM dianalisis menggunakan perangkat lunak imageJ menunjukan rata-rata celah interfasial yang terbentuk antara GIC dan enamel (6.923 µm), sedangkan antara GIC dengan dentin (13.160 µm). Selain itu, pada Alkasite tidak ditemukan adanya celah interfasial. Hasil EDX antara GIC dengan struktur gigi didapatkan adanya unsur fosfor (P), kalsium (Ca) dan fluor (F) lebih tinggi dibanding antara Alkasite dengan struktur gigi. Keberdaan unsur P, Ca, dan F mampu memberikan potensi remineralisasi pada gigi di sekitar restorasi. Kesimpulan penelitian ini material Alkasite dengan pengaplikasian bonding agent menunjukkan adaptasi marginal yang lebih baik dibandingkan material restorasi GIC, namun Alkasite dengan pengaplikasian bonding agent kurang baik dalam hal memberikan potensi remineralisasi ke struktur gigi dibanding GIC.

Ideally, restorative materials must not only be able to adapt well to the cavity, be aesthetic, not irritate, but also must be able to bond well with the tooth structure. Alkasite restoration materials began to be developed in 2016 which have the same color as teeth and are claimed to have better mechanical strength when compared to Glass Ionomer Cement (GIC). This study aims to analyze the interface between GIC and Alkasite restoration materials and tooth structure using the Scanning Electron Microscope (SEM) test and the Energy Dispersive X-ray Spectroscopy (EDX) Mapping test. Specimens in this study used maxillary premolars restored with GIC and Alkasite in class V G.V Black cavities and stored in an incubator for 1 month at 37°C. The specimen was cut longitudinally from the bucopalatal direction, then analyzed at the interface of the restoration using SEM and EDX mapping of the Thermo Scientific Prisma E brand. SEM results were analyzed using the ImageJ software showing the average interfacial gap formed between GIC and enamel (6,923 µm), while between GIC and dentin (13,160 µm). In addition, in Alkasite no interfacial gaps were found. The EDX results between GIC and tooth structure found that the elements phosphorus (P), calcium (Ca) and fluorine (F) were higher than those between Alkasite and tooth structure. The presence of elements P, Ca, and F can provide potential for remineralization of the teeth around the restoration. The conclusion of this study was that the Alkasite material with the application of a bonding agent showed better marginal adaptation than the GIC restorative material, but the Alkasite with the application of a bonding agent was less good in terms of providing remineralization potential to the tooth structure compared to GIC.
