Abstract

Amalgam merupakan bahan restorasi gigi yang umum digunakan, namun mengandung merkuri hingga 43–54%, penggunaannya berisiko bagi kesehatan sehingga mulai digantikan oleh komposit resin. Kombinasi silika dan mikroselulosa serat daun nanas masih belum dikembangkan sebagai alternatif bahan restorasi gigi. Oleh karena itu, penelitian ini dilakukan untuk mengetahui pengaruh kombinasi cellulose mikrocrystals serat daun nanas dan silika termodifikasi melalui variasi rasio penambahan kedua material tersebut sehingga didapatkan bahan restorasi gigi dengan filler alami sebagai pengganti filler amalgam yang mengandung merkuri. Penelitian ini akan dilakukan dengan tiga tahap yaitu sintesis, silanisasi, dan polimerisasi. Variabel rasio mikroselulosa dan silika yang digunakan adalah 30%:0% ; 20%:10% ; 15%:15%; 10%:30% ; 0%:30%. Analisa dilakukan menggunakan FTIR, SEM, XRD, dan Fracture Test.

Amalgam is a commonly used dental restorative material; however, it contains mercury up to 43–54%, posing health risks, which has led to its gradual replacement by resin composites. The combination of silica and pineapple leaf fiber-based microcrystalline cellulose has not yet been widely developed as an alternative dental restorative material. Therefore, this research was conducted to investigate the effect of combining microcrystalline cellulose from pineapple leaf fiber and modified silica through variations in their composition ratios, aiming to develop dental restorative material with natural fillers as a substitute for mercury-containing amalgam. The study consists of three stages: synthesis, silanization, and polymerization. The composition ratios of microcellulose to silica used were 30%:0%, 20%:10%, 15%:15%, 10%:20%, and 0%:30%. Analyses were conducted using FTIR, SEM, XRD, and fracture testing.
