Dental cement composition comprising a polymerizable polyacidic polymer having repeating units in the polymer backbone, which are represented by the following formula (I), (II), and/or (III):
wherein
X
represents O, S, or NR', whereby R' represents a hydrogen atom or a straight or branched C1-C6 alkyl group, C3-C6 cycloalkyl group, or C4-C8 cycloalkylalkyl group,
Y
a group of the following formula (IV)
wherein each of L1, L2, L3 and L4,
which are independent from each other represents a single bond, a straight or branched C1-C6 alkylene group, a straight or branched C1-C6 alkenylene, or a straight or branched C1-C20 alkylene group which includes 1 to 8 atoms selected from oxygen and sulfur atoms,
X'
represents O, S, or NR", whereby R" represents a hydrogen atom or a straight or branched C1-C6 alkyl group, C3-C6 cycloalkyl group, or C4-C8 cycloalkylalkyl group,
m is 0 to 3, and
n is 0 to 3,
provided that X' is O when n is 0.
