| 1-10. GENERAL Dental cements are generally low strength materials prepared by mixing a powder with a liquid. These cements vary in their chemical composition, properties, and uses. Dental cements have lower heat conductivity than do metallic restorative materials. Dental cements, however, have the disadvantages of relatively low strength, varying degrees of solubility in mouth fluids, and setting shrinkage. As a group, they are more natural in appearance and are easier and faster to use. Although they are widely used in restorative dentistry, dental cements are considered to be among the least permanent of restorative materials. Four types of cement used in dentistry are zinc phosphate cement, polycarboxylate cement, glass ionomer cement, and zinc oxide and eugenol cement. |
