Preparation of Chemical Solution for the Provisional Cement Remnant Cleaning in Dental Crown

It is important in dentistry that the provisional cement should be cleaned thoroughly from the crown before definitive cementation. The provisional cement has been removed by physical means such as curette, scaler, pumice, or sand-blasting with alumina particles, which is time-consuming, irritating, tedious, even causing crack. To avoid such troubles occurring through such physical cleaning means, the chemical solutions for dissolving the provisional cement remaining in dental crown were prepared, and solubilizing power of the solutions was measured and compared. The solution composed of MEA, NaOH, chloride chemicals (CHCl 3 , CCl 4 , CH 2 Cl 2 ), surfactants (Igepal, Tween20), chelating agent (EDTA), and Ethyl cellosolve was most effective for dissolving the provisional cement.
