Embodiment 1
[0019] The concrete method that embodiment one proposes is as follows:
[0020] Before composite resin bonding and filling, the surface of hardened dentin was pretreated with 35% phosphoric acid gel for 30 seconds; 2 Rinse with O for 30 s; after drying, pretreat the surface of hardened dentin with 5% or 10% NaClO solution for 60 s, and rinse with H 2 O Rinse for 30 s, and after drying, complete the pretreatment of the hardened dentin surface.
[0021] After pretreatment of the hardened dentin surface, one-step self-etching adhesive (AdperTM Easy One, 3MESPE, USA) was selected for routine rubbing, and then composite resin (3M Filtek Z250A3, 3M ESPE, USA) was used for filling and curing.
Embodiment 2
[0022] The specific method that embodiment two proposes is as follows:
[0023] The hardened dentin surface was pretreated with 35% phosphoric acid gel for 30 s. Rinse for 30s and dry. The surface of hardened dentin was pretreated with 5% NaClO solution for 60s, rinsed for 30s, and dried to complete the pretreatment of hardened dentin surface. Then, choose AdperTM Easy One one-step self-etching adhesive, 3M Filtek Z250A3 composite resin for filling and curing.
[0024] The feasibility and correctness of the method proposed in the embodiment are verified through the following experiments. For isolated teeth, the following pretreatment methods were used:
