A dental adhesive material kit may have desirable adhesive properties for tooth structure, and, while ensuring appropriate strength, may allow easy removal of excess cement in a semi-cured state created by temporarily applying light to excess portions of cement with a photoirradiator. Such a dental adhesive material kit may include a dental aqueous adhesive composition (A) and a dental curable composition (B), satisfying the inequality (I)0≤t2−t1≤3.0  (I),wherein t1 (min) is a contactual polymerization start time of the dental aqueous adhesive composition (A) and the dental curable composition (B), and t2 (min) is a polymerization start time of the dental curable composition (B).

The present invention relates to a method of marking a tooth or teeth for identification purposes by adhering a product to the tooth that is visible to the practitioner under UV (black) light. This disclosure provides a dental bonding agent containing a resin and a component that allows the material to glow under UV black light. In order to prevent wrong-site tooth extraction, the referring dentist, for example, can apply the inventive product to a particular tooth to mark and identify the tooth to be treated by another practitioner. This mark is not visible under normal circumstances (under normal lighting conditions) and therefore would not be noticeable, but identifies the particular tooth by glowing under black light.
