Anterior composite is a dental restorative use to restore damage anterior teeth due to caries or trauma. Their colour that mimics the natural tooth colour has resulted in a high demand by patients. Resin composite that normally used for dental restorative can be classified into different types which are depended on their filler sizes, such as micro composite, macro composite and hybrid composite. However those particular classifications of the resin composite have less aesthetic and low strength values. With a nanotechnology, systhesis of filler at nano size level can be achieved, resulted a nanocomposite with high aesthetic values and high strength. However, Commercial nanocomposite in the market is quite limited and also at a high price. For this reason, a group of researches at School of Dental Sciences, USM took the initiative and has successfully developed an anterior nanocomposite for dental filling known as KeLFiL. KeLFiL is an anterior resin composite where monodispered spherical silica nanoparticles synthesized via sol-gel process has been used as fillers. The product was nontoxic with properties such as flexural, compressive and hardness, water sorption and solubility that complied with the ISO standard of dental filling composites.
