N ‐Substituted 3‐amino‐2‐hydroxypropyl methacrylates have been evaluated as adhesives for calcium metaphosphate crystalline glass‐ceramic, a potential esthetic dental restoration material. Although the adhesion to the ceramic was found to be much more difficult and dependent on the kinds of substituents than that of tooth enamel, monomers having a carboxyl group showed specifically high adhesive tensile strength. The strength tended to decrease as the hydrophobicity and molecular bulkiness increased. Surface treatment of the ceramic, especially with sodium hydroxide, proved effective in terms of both strength and durability for the carboxyl‐containing monomers. Scanning electron microscopy analysis confirmed the importance of surface irregularity due to the alkaline treatment.
