IN VITRO EVALUATION OF THE EFFECTS OF DIFFERENT CHEMICAL SOLVENT AGENTS ON SHEAR BOND STRENGTH OF CERAMIC ORTHODONTIC BRACKETS

Objective:In this study, the effects of different chemical solvents such as acetone, ethanol, dimethyl sulfoxide (DMSO), peppermint oil, and hot water on the shear bond strength (SBS) of mechanically and chemically bonded ceramic brackets were examined.Their use for facilitation of the debonding process in practice was evaluated regarding Laundry D
