A method for treating a root canal using a calcium hydroxide component-based composition as intracanal medication,
- wherein the composition comprises:
- calcium hydroxide or a calcium hydroxide producing component as a powder component;
- and
- at least one of dimethyl sulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP) and diethylene glycol monoethyl ether (DEGEE) as a liquid component,
- wherein the at least one of the DMSO, NMP and DEGEE is included at 70% or more of weight of liquid components of the composition, and
- wherein the method comprises the steps of:
- injecting the composition into a root canal such that the at least one of the DMSO, NMP and DEGEE acts in conjunction with hydroxyl ions produced by the calcium hydroxide to peel off a biofilm or smear layer in the root canal;
- and
- removing the composition from the root canal after a predetermined period of time.
