Embodiment 1

[0032] Methods: 3 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, freshly extracted for orthodontics (the patient gave informed consent, and the residual soft tissue on the root surface was removed with a curette after extraction, 4 ℃ physiological saline and stored for later use, the time shall not exceed 4 weeks), the root of the tooth was embedded with self-setting resin, the enamel of the occlusal surface was ground to expose the dentin, and it was used as a test piece for later use.

[0033] 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) ;

[0034] Materials: self-curing methyl methacrylate base resin (Shanghai Medical Ins...

Abstract

The invention discloses a material for forming mineral substance in a dentinal tubule by use of delayed reaction and application thereof, and belongs to the technical field of dentistry repairing materials. The material is characterized by comprising a reagent A, wherein the reagent A is EDTA-2Na, calcium chloride and sodium fluoride aqueous solution, the pH value is regulated by the sodium hydroxide and the hydrochloric acid; a reagent B is the mixed solution of potassium oxalate aqueous solution and n-butyl alcohol; the reagent A and the reagent B are mixed, continuously and quickly stirred to obtain a reagent C; the reagent C is immediately painted on the dental face for exposing the dentinal tubule, so that the reagent C can smoothly enter the dentinal tubule or a deep layer; the delayed reaction is started, the insoluble calcium oxalate and like mineral substances are gradually generated in the tubule of the dentinal tubule so as to block the dentinal tubule.

Description

technical field [0001] The invention belongs to oral cavity tooth restoration materials, and relates to a material aimed at forming mineral seals in dentin tubules and an application method thereof. Background technique [0002] The opening of dentinal tubules can lead to dentine sensitivity. Dentin sensitivity refers to the short and sharp pain of exposed dentine in response to external stimuli. Typical stimuli include temperature stimulation, air blowing stimulation, mechanical stimulation and chemical stimulation. The mainstream theory to explain the sensitization of stimuli is the hydrodynamic theory, that is, external temperature, mechanical and other stimuli act on the tooth surface with exposed dentinal tubules, resulting in changes in the fluid flow state in the dentinal tubules, stimulating the presence of dentinal tubules Nerve fibers, which in turn lead to dentin sensitivity, resulting in discomfort. [0003] Most of the recent methods of treating dentin sensitiv...
