Objectives: The aim of this study was to assess the potential of a smear-layer removing agent (citric acid) vs an accepted gutta-percha-softening agent (xylol) as an alternative substance for removing the root canal filling materials, while investigating the potential for associated demineralization effects.
Materials and methods: Seventy healthy, recently extracted premolars were used, ten as control, with sixty with their canals enlarged, shaped and cleaned and obturated using lateral compaction. Teeth were distributed into 3 groups as follows: 1) no solvent and mechanical removal of the filling materials; 2) 1 ml of Xylol for 1 minute followed by mechanical removal; and 3) 10% citric acid for 1 minute followed by mechanical removal. Two sections of the root were used, one for Raman spectroscopy analysis to evaluate morphological changes i.. View More»
