Adhesive Qualities of Different Dental Cements

Abstract

Orthodontic bands were cemented to extracted teeth with four types of dental cement. The force values required to dislodge the bands after storage in water for 24 hours were recorded and a comparison of the cements was made. The amount of residual cement remaining on the enamel surface and the band was also recorded to determine whether the fracture was in the cementing agent or at the enamel surface. The silico-phosphate and the resin cements required a greater force for dislodgment than did the zinc phosphate and polycarboxylate cements. They also were found to have a higher percentage of residual cement still adhering to the enamel surface after the bands had been dislodged.
