The propose of this dye and SEM study was to evaluate the cleansing capabilities of two solvents ethyl alcohol and chloroform, prior to dentin bonding in the coronal chambers of endodontically treated teeth obturated with either a eugenol or resin-based sealer. A total of 156 extracted human molar teeth were divided into 6 groups and obturated with either a eugenol-based (Roth's, Grossman), or a resin-based (AH Plus, Kerr) endodontic sealer. Samples were thermocycled and placed into India Ink or silver nitrate for (SEM samples). All teeth were cleared and evaluated for coronal microleakage. A significant difference was found between the six groups p = 0.002 (Legistic linear analysis). Conclusion. When using eugenol-based endodontic sealer it is imperative to clean the coronal chamber with either ethyl alcohol or chloroform prior to dentin bonding. When using a resin-based endodontic sealer it is not necessary to use a solvent to clean the coronal chamber.
