The Effectiveness of the Organic Volatile solvents in Retreatment of Root Canal System( in vitro Study)

Abstract

This study tested the hypothesis that root canal sealer cements insoluble in the volatile solvents chloroform and eucalyptol. Forty samples were prepered for each material ( AH26, Endofil sealers) these were divided into eight groups of five; for immersion in chloroform or eucalyptol for 30 s, 1 min, 5 min, 10 min. Clear differences were shown in the solubility profile of major classes of root canal sealer cements in two common volatile solvents. The resulte of this study shows that the AH 26 was significantly more soluble than the other material in both chloroform and eucalyptol in all immersion times. Also shows that the chlorofom is more soluble than eucalyptol for both sealer cements.
