Problems solved by technology

[0003] The harm of dental caries has the following points: (1) it often causes inflammation at the root tip of the tooth and other parts, and local swelling in severe cases: if pus and bacteria are absorbed, it can cause sepsis or bacteremia; (2) the bad tooth root cannot chew food, Increase the burden on the gastrointestinal tract; (3) For the elderly, severe caries can cause most or all of the teeth to be lost, which is not conducive to the health of the elderly
[0004] The bonding strength and compressive strength of the existing dental caries adhesives are poor, and they are easy to fall off after filling treatment, especially after chewing food, requiring secondary treatment, which increases the difficulty of treatment; at the same time, the existing dental caries adhesives are Easy to dissolve in the mouth after use, affecting the therapeutic effect

Abstract

The invention discloses a bonding agent for decayed tooth filling treatment and a preparing method thereof. The bonding agent comprises, by weight, 34-52 parts of epoxy resin, 5-13 parts of sodium hexafluorisilicate, 6-19 parts of glycerophosphoric acid methacrylate, 12-17 parts of hydroxyethyl cellulose, 15-22 parts of talcum powder, 32-43 parts of glycerinum, 3-8 parts of methacrylic acid, 12-25 parts of dibutene and 6-17 parts of triethanolamine. The prepared bonding agent is high in bonding strength, good in compressive property and not prone to being dissolved in saliva.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to an adhesive used for dental caries filling treatment and a preparation method thereof. Background technique [0002] Dental caries, commonly known as tooth decay and tooth decay, is a bacterial disease that can lead to secondary pulpitis and periapical periodontitis, and can even cause alveolar bone and jaw inflammation. If it is not treated in time, the lesion will continue to develop, forming caries, and eventually The complete destruction of the crown disappears, and the final result of its development is the loss of the tooth. Dental caries is characterized by high incidence and wide distribution. It is the main common disease of the oral cavity and one of the most common human diseases. The World Health Organization has listed caries as one of the three major human diseases for prevention and treatment along with tumors and cardiovascular diseases. [0003] The harm of ...
