HISTORY
 Luting is derived from a
greek word LUTUM –
meaning mud. Primarily
cements were used to fill the
gap between restoration and
tooth structure. There was
no bonding.

as high as possible
 Modulus of elasticity should be as much
as dentine ie 13.7 Gpa.

 Solubility : should be as low as possible
according to ANSI /ADA specification it
should be maximum of .2 % of weight in
water.
 Adhesion to tooth structure and
