Utilization of Silica Nanoparticles from Rice Husks for Improving the Mechanical Properties of Dental Materials: A Literature Review

Rice husk is a waste product whose utilization not optimal in Indonesia. husks contain organic materials the form of cellulose, hemicellulose, and lignin; minerals silica, alkali, trace elements. The silica content rice very high, ranging from 87-97% to other minerals. Silica nanoparticles were synthesized through various methods, including sol-gel method, combustion combination obtain purity size particles up manometer scale. Mixing dental material at certain concentration effective producing better mechanical properties. have potential as fillers reinforcements that can improve properties materials. Besides that, price more economical because raw come Indonesian natural waste. This literature review aims describe method synthesizing their effectiveness improving
