Glass ionomer cement merupakan bahan restorasi gigi. Penggunaan GIC memiliki kelebihan berupa kemampuan pelepasan ion fluorida, namun GIC juga memiliki kekurangan. Upaya mengatasi kekurangan GIC salah satunya adalah dengan penambahan filler berupa nanoselulosa kulit durian (Durio zibethinus Murr.). Tujuan penelitian ini untuk mengetahui pengaruh penambahan nanoselulosa kulit durian terhadap kemampuan pelepasan fluorida pada GIC tipe II. Jenis penelitian berupa eksperimental laboratoris dengan rancangan penelitian post-test only control group design. Nanoselulosa kulit durian diisolasi dengan metode hidrolisis asam H2SO4, Bentuk partikel nanoselulosa adalah whiskers dengan rerata panjang 87.32 nanometer dan rerata diameter 6.66 nanometer. Sebanyak 32 sampel dibagi dalam 4 kelompok, yaitu GIC tipe II dengan penambahan nanoselulosa kulit durian konsentrasi 0,5%, 1%, 1,5%, dan tanpa penambahan nanoselulosa sekam kulit durian. Sampel direndam dalam saliva buatan dan di uji menggunakan metode spektrofotometri. Analisis data menggunakan One-Way ANOVA diikuti dengan uji post-hoc LSD. Hasil analisis statistik menunjukkan rerata kadar pelepasan fluorida paling tinggi terdapat pada kelompok GIC dengan penambahan nanoselulosa kulit durian konsentrasi 1,5% yaitu 13.67 ± 0.12 ppm dan yang paling rendah terdapat pada kelompok kontrol sebesar 10.03 ± 0.09 ppm. Simpulan dari penelitian ini adalah terdapat pengaruh penambahan nanoselulosa kulit durian (Durio zibethinus Murr.) terhadap jumlah pelepasan ion fluorida pada GIC tipe II.

Glass ionomer cement is a dental restorative material. The use of GIC has advantages in the form of the ability to release fluoride ions, but GIC also has disadvantages. One of the efforts to overcome the shortage of GIC is by adding filler in the form of durian (Durio zibethinus Murr.) skin nanocellulose. The purpose of this study was to determine the effect of adding durian peel nanocellulose on the ability to release fluoride in type II GIC. This type of research is a laboratory experimental study with a post-test only control group design. Durian peel nanocellulose was isolated by the H2SO4 acid hydrolysis method. The shape of the nanocellulose particles was whiskers with an average length of 87.32 nanometers and an average diameter of 6.66 nanometers. A total of 32 samples were divided into 4 groups, namely GIC type II with the addition of nanocellulose durian skin concentrations of 0.5%, 1%, 1.5%, and without the addition of nanocellulose durian skin husks. Samples were immersed in artificial saliva and tested using the spectrophotometric method. Data analysis used One-Way ANOVA followed by LSD post-hoc test.The results of statistical analysis showed that the highest average level of fluoride release was found in the GIC group with the addition of 1.5% durian peel nanocellulose, namely 13.67 ± 0.12 ppm and the lowest was in the control group, which was 10.03 ± 0.09 ppm. The conclusion from this study is that there is an effect of adding nanocellulose from durian peel (Durio zibethinus Murr.) to the amount of fluoride ion released in GIC type II.
