Embodiment 1

[0026] 1. A chemical dissolution compound preparation method for dental gutta-percha root canal fillings, comprising the following steps:

[0027] A: Take commercially available D-limonene, distill under reduced pressure at a vacuum of 1.2×10Pa and 60°C to obtain D-limonene with a purity greater than 95% for use (rotary evaporator, RE-52A, Shanghai Zhenjie Experimental Equipment limited company);

[0028] B: Take 70 mL of the purified D-limonene obtained in step A, add 70 mg of egg yolk, and dissolve it completely;

[0029] C: take by weighing 2.572g sorbitan fatty acid ester, be dissolved in the B step solution;

[0030] D: Weigh 3.36g of sodium edetate, dissolve it in 20mL of distilled water, adjust the pH value to 8 with sodium hydroxide, and obtain a 0.5M sodium edetate solution;

[0031] E: Weigh 2.556g of sodium dodecyldiphenyl ether disulfonate, and dissolve 2.092g of sodium dodecylbenzenesulfonate in 10mL of distilled water;

[0032] F: the solution obtained in step...

Abstract

The invention relates to a dental chemical removal compound formula for root-canal filling of gutta pertscha and a preparation technique. The preparation technique is characterized by comprising the following steps: (1) dissolving 2.572g of sorbitan aliphatic ester (Span40) and 70mg of protein lututrin in 70mL of D-limonene to obtain a D-limonene oily matter; (2) dissolving 3.36g of sodium ethylene diamine tetracetate (EDTA), 2.556g of dodecyl diphenyl ether sodium disulfonate and 2.092g of sodium dodecyl benzene sulfonate in deionized water (pH=8) to obtain an EDTA aqueous phase compound; and (3) slowly dropwise adding the aqueous phase liquid obtained in the step (2) into the oil phase liquid obtained in the step (1), simultaneously emulsifying by using an ultrasonic or high-shear force emulsifying machine, centrifugalizing an emulsion and abandoning precipitate to obtain the required emulsion compound. The clinical effect of the product obtained by the invention is similar to that of removing root-canal gutta pertscha by clinically using chloroform but has the biosafety which is uncomparable with chloroform.

Description

technical field [0001] The invention belongs to biomedical material technology, and is used for a chemical compound preparation technology for removing gutta-percha fillings in original root canals in oral clinical root canal treatment. Background technique [0002] Root canal therapy is currently the most effective treatment method to completely solve irreversible pulp inflammation, necrosis and other diseases in oral clinical practice. With the development of standardized root canal treatment technology, root canal treatment has been popularized in hospitals at all levels in our country. With the increase in the number of root canal treated teeth, and the continuous improvement of tooth defect restoration technology for root canal treatment quality, the number of re-treatment cases of original incomplete root canal treatment has gradually increased. The removal of the filling in the original root canal treatment is one of the most time-consuming, difficult, and most prone...
