Embodiment 1
[0033] Embodiment 1: Comprising a self-etching primer composition and an adhesive composition; for the acid resistance of the dentin surface after laser preparation, the self-etching primer composition includes a polymeric monomer containing an acidic group body, adjust the pH value of the self-etching primer composition from 1 to 1.5, and the self-etching pH value of the adhesive composition after the fast machine preparation is 2;
[0034] It can exist stably at room temperature and undergo photoinitiated polymerization; after preparing the adhesive composition, store it in a thermostat at 37 degrees for one month, and the adhesive strength does not change before and after storage;
[0035] For laser preparation of the 8-15 micron thick sub-corrosion layer of the tooth tissue, the resin monomer in the adhesive composition can penetrate into the sub-corrosion layer, polymerize through the light-curing resin monomer, and the bonding material in the adhesive composition Cured t...
Embodiment 2
[0046] Example 2: The double-liquid adhesive composition for laser tooth preparation of the present invention According to preliminary work, with the widespread use of lasers in dental clinics, especially the promotion of lasers in the treatment of dental caries, the current adhesive system will not be able to To meet clinical needs, a new system that can provide reliable and stable bonding effects for laser-prepared dental tissues will be urgently needed. See Table 1:

Embodiment
[0049] The content of the embodiment is mainly divided into 4 parts:
[0050] 1) Observation of the physical and chemical properties of dentin after Er:YAG laser preparation and fast machine cutting
[0051] For the measurement of the hardness and elastic coefficient of the secondary corrosion layer, through the comparative analysis of the distribution of sulfur, phosphorus, and calcium elements in the dentin, discuss the influence of the fast machine and Er:YAG laser on the dentin, and discuss the effect of laser irradiation on the dentin. Influence of physicochemical properties.
[0052] 2) Developed adhesive composition
[0053] In view of the characteristics of dentin after laser preparation, the two-component adhesive composition X for laser preparation of dentin was invented and developed.
[0054] 3) Adhesive strength test
[0055] Compare the adhesive composition X with the 5th generation, the 7th generation fast machine preparation tooth tissue adhesive system with...
