Abstract
This study evaluated the wear resistance and sealing property of endodontic temporary restoratives by means of functional stressing using a wear simulator. The pulp chamber of 28 extracted molars was opened and filled with cotton, and then the cavity was filled with a temporary material — Caviton, Temporary Pack, Neodyne-α, or TERM. Specimens were subjected to a wear test, and data for wear and dye penetration were analyzed by one-way ANOVA independently (p<0.05) . Wear values of Neodyne-α (0.09±0.05 mm) and TERM (0.24±0.06 mm) were significantly less than those of Caviton (1.79±0.15 mm) and Temporary Pack (1.02±0.40 mm) . In terms of dye penetration, Neodyne-α leaked significantly less than the other materials at 0.40±0.32 mm. On the other hand, there were no significant differences between TERM (1.30±0.57 mm) and Temporary Pack (2.10±0.12 mm) , and between Caviton (2.60±0.41 mm) and Temporary Pack.
