Problems solved by technology

[0004] In summary, the problems in the prior art are: the existing deciduous tooth root canal filling materials cannot meet all the characteristics of the ideal deciduous tooth root canal filling drug; the absorption rate of the compound preparation of iodoform and calcium hydroxide or zinc oxide eugenol often has Root dyssynchrony; zinc oxide eugenol preparations, absorption rate often slower than deciduous roots
If the material absorption is earlier than the physiological absorption of the deciduous teeth itself, then it will cause "root filling" to form an infection focus; if the material absorption is later than the physiological absorption of the deciduous teeth themselves, then the eruption of the inherited permanent teeth will be affected

preparation example Construction

[0026] Such as figure 1 As shown, the preparation method of the deciduous root canal filling material provided by the embodiment of the present invention specifically includes:

[0027] S101, weigh calcium hydroxide and iodoform powder according to the volume ratio.

[0028] S102, weighing the quantitative medicine vaseline.

[0029] S103, mixing calcium hydroxide, iodoform powder and medical vaseline into a paste at room temperature, and stirring evenly, to obtain the root canal filling material for deciduous teeth.

[0030] The method for preparing the root canal filling material for deciduous teeth provided by the embodiment of the present invention further includes: the prepared root canal filling material for deciduous teeth should be stored at room temperature, avoiding direct sunlight.

Embodiment 1

[0033] The composition of the deciduous tooth root canal filling material provided by the embodiment of the present invention:

[0034] 1. Calcium hydroxide, molecular formula: Ca(OH) 2 . CAS accession number: 1305-62-0. The main component of the material, calcium hydroxide, has antibacterial and antibacterial properties, can promote cementum hyperplasia at the root tip, and induce the continued development and formation of hard tissue at the root tip.

[0035] 2. Iodoform, also known as triiodomethane Molecular formula: CHI3. CAS registration number: 75-47-8 Main ingredients of the material. When iodoform is applied to local tissues, elemental iodine can be gradually released, and iodine element has a good disinfection and antiseptic effect. Iodoform has X-ray opacity, and its filling condition and changes in the future can be observed.

[0036] 3. Vaseline, molecular formula: C(n)H(2n+2). CAS accession number: 8009-03-8. It is mainly a chemically inert hydrocarbon, an...

Abstract

The invention belongs to the technical field of dental preparations, and discloses a deciduous tooth root canal filling material and a preparation method thereof. The deciduous tooth root canal filling material is composed of 30-50% by volume of calcium hydroxide, 10-20% by volume of iodoform and 30-50% by volume of Vaseline. The preparation method specifically comprises the following steps: weighing and extracting calcium hydroxide and iodoform powder according to a volume ratio; weighing the certain amount of medical Vaseline; and uniformly mixing the calcium hydroxide, the iodoform powder and the medical Vaseline at normal temperature, fully stirring to form a paste, and uniformly stirring the paste to obtain the deciduous tooth root canal filling material. The deciduous tooth root canal filling material belongs to an iodoform and calcium hydroxide composite preparation; and the adhesion of the root canal wall is further improved through material proportioning, and the material absorption rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of dental preparations, and in particular relates to a deciduous root canal filling material and a preparation method. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the ideal medicine for root canal filling of deciduous teeth should have the following characteristics: insoluble in water; The tube wall should be adhesive and non-shrinking; stable anti-infection ability; no stimulation to the root tip tissue, no coagulation effect on the residual tissue in the root; superfilling material is easy to be absorbed; no hard tissue that affects the inheritance of permanent tooth germ Agglomerate; can promote calcification and hard tissue formation of apical tissue, and close apical foramen; harmless to gingival tissue. [0003] At present, there are many kinds of root canal filling medicines used clinically, including calcium hydroxide preparations, z...
