Hydrophobic composite restorative materials and their use in tooth treatment

摘要

Penetration of fluids between a tooth and a restoration is prevented, without chemical adhesive of the restorative material to the tooth by forming the restoration from a dental composition which is hydrophobic to the extent that the advancing contact angle of water or saliva on the restorative material is at least about 130 DEG . The hydrophobic nature of the contoured surface of the composite also minimizes staining by soluble dyes and accretion of hydrophilic gelatinous surface films.
