Specifically, the bonding material was applied, air blown, and then light was irradiated using a dental LED light irradiator G Light Prima II (manufactured by GC) to cure the bonding material. At this time, after irradiating the light for 10 seconds, the operation of shifting the diameter of the irradiation window by half was repeated until the entire bonding material was irradiated with the light.
- the composite resin was cured by irradiating with light using a dental LED light irradiator G Light Prima II (manufactured by GC). At this time, after irradiating the composite resin with light for 10 seconds, the operation of shifting the diameter of the irradiation window by half was repeated until the entire composite resin was irradiated with light to obtain a test piece. Next, after taking out the test piece from the mold, the test piece was stored in water at 37 ° C.

Specifically, using an autograph (manufactured by Shimadzu Corporation), a load in the shearing direction is applied to the joint surface between the hardened glass ionomer cement and the hardened composite resin to break it, and then break it. The cross section was observed to evaluate the adhesiveness of the cured composite resin to the cured cement of glass ionomer cement. The adhesiveness of the cured composite resin to the cured glass ionomer cement was determined according to the following criteria.
