Problems solved by technology

For improving the bonding effect, from full acid etching to self-etching, adhesives have also been updated and have made significant progress, but they have been facing many problems, such as demineralization caused by acid etching and exposure of collagen fibers, affecting Antiaging Properties of Dentin Bonds

Embodiment 1

[0013] Methods: Human premolars with intact crowns, no caries and cracks were selected from the Department of Oral and Maxillofacial Surgery of the School of Stomatology, Capital Medical University. The salt water is stored for later use, and the time is not more than 4 weeks), and the root is embedded with self-setting resin, the enamel is ground away, and the dentin is exposed, and it is used as a test piece for later use.

[0014] Equipment: scanning electron microscope (Phenom proX, Phenom-World B.V., Netherlands), metallographic sample pre-grinding machine (YM-2A, Shanghai Metallographic Machinery Equipment Co., Ltd.), low-speed cutting machine (Isomet 4000Linear Precision Saw, Buehler, USA) , Universal testing machine.

[0015] Materials: self-curing methyl methacrylate base resin (Shanghai Medical Instrument Co., Ltd. Dental Material Factory, referred to as: self-curing resin), composite resin (Z250, 3M, the United States), adhesive (singlebond, Japan), Acid etchant (G...

Abstract

The invention discloses an acid etching mineralizer for increasing adhesion of dentin, and belongs to the technical field of dental restoration agents. A certain proportion of a soluble fluoride saltis added into an acid etching agent phosphoric acid. 0.5-5 g of the fluoride salt is correspondingly added into every 100 ml of 5-50% phosphoric acid. Fluoride is used as a part of a treating agent and acts on the dentin bonding surface together with phosphoric acid, and after conventional water washing is performed, fluoride is generated and deposited on the surface of dentin and blocks dentinaltubules while acid etching demineralization is performed, so that exposure of collagen fibers on the surface of the acid etched dentin is reduced, the influence of liquid in dentin tubules on adhesionis reduced, the sensitivity of teeth to external stimulation is reduced, mineralization of the dentin is promoted, and the adhesion and the anti-aging performance are improved.

Description

technical field [0001] The invention belongs to the technical field of oral tooth restoratives, and relates to the application of acid erosion mineralization before dentin bonding, forming fluoride on the surface of dentin or in dentin tubules to isolate tubule fluid, hardening dentin, and improving adhesion. Relay and improved anti-aging properties. Background technique [0002] Dentin bonding has always been a problem in the field of oral cavity, because dentin is different from enamel, and there are large differences in structure and physical and chemical properties. Dentin contains more organic matrix, which has a negative impact on the bonding force. influences. Moreover, there are many dentine tubules extending from the pulp cavity to the surface of the dentin, and there is dentine fluid in the dentine tubules. External stimuli to the dentin will be transmitted to the pulp cavity through the dentine tubules, which will bring discomfort to the human body. Since Buonoc...
