| Research Abstract |
Components of mastication mediums; fiber and abrasive particle, affected on wear of dental porcelain which is the hardest material in dental materials. Wear of porcelain increased substantially when abrasive particle was combined with 5 % cellulose which was expected to reduce wear by increasing a viscosity of medium. On the contrary, wear of porcelain decreased by increasing of abrasive particle according to experimental condition. Thus components of mastication medium showed inverse effect on wear of porcelain in some situation.
