Effect of Storage Temperature on the Shelf Life of Self-adhesive Resin Cements.

Purpose: To compare the bonding performance of three new self-adhesive resin cements to human dentin after storage under two different conditions.

Materials And Methods: Buccal, lingual, mesial, and distal dentin surfaces of 36 human molars were abraded to directly below the enamel with #600 SiC papers. The teeth were divided into two main test groups.
