Description
Technical Field
The invention belongs to the technical field of biomedical materials, and particularly relates to an injectable silicon-phosphorus-calcium-based dental paste with high osteogenesis activity, and a preparation method and application thereof.
Background
Dental pulp diseases and periapical diseases are common and multiple diseases of the oral cavity. According to the periapical lesion of the dental pulp of a patient, the clinical treatment method of the dental pulp disease mainly comprises pulp capping operation, pulp chamber bottom and root canal perforation repair, root canal treatment operation, root tip induction forming operation, root tip barrier operation, root canal filling, blood circulation reconstruction and the like. The factors determining the therapeutic effect of dental pulp diseases are numerous, and dental filling restoration materials are the most critical step. The silicon-calcium-based bioceramic paste is a material with better comprehensive performance in the field of dental pulp at present, and the mineral trioxide aggregate (MTA, mineral Trioxide Aggregate) is the first silicon-calcium-based bioceramic material entering clinical application, and has excellent bioactivity, biocompatibility, bone-like apatite mineralization capacity, sealing capacity, certain antibacterial performance and the like.
However, the MTA materials of the initial version have disadvantages such as poor operability, difficulty in injection, poor anti-collapsibility, insufficient curing properties, and susceptibility to discoloration of the tooth. Early MTA formulations had a strong gritty feel, were difficult to modulate, and were difficult to deliver into the long and narrow curved root canal. In addition, MTA slurries are prone to free particle collapse in aqueous environments, e.g., in revascularization, MTA slurries are often placed on blood clots to seal the root canal and induce dental pulp mineralization. However, the unset paste collapses upon contact with fresh blood clot, which can lead to micro-leakage of free paste particles and potential inflammatory reactions. The curing time of MTA is as long as about 4 hours, and the overlong curing time not only prolongs the treatment time and increases additional operation procedures, but also can improve the slurry collapse and displacement risks.
Researchers have accelerated the hydration of calcium silicate-based materials by doping with inorganic salts (e.g., calcium chloride and calcium carbonate, etc.) to shorten their cure time. In addition, by using organic gelling agents such as sodium alginate, chitosan, gelatin and the like, the anti-collapsibility and the operation characteristics of the silicon-calcium-based paste can be effectively improved, after the organic additive is introduced, an organic gel film can be formed on the surfaces of paste particles, the erosion of external moisture can be effectively resisted, the organic matters have good rheological property and gelling property, and the binding capacity and the flowability of the paste particles can be enhanced. However, the organic matters adhering to the surfaces of the paste particles inevitably hinder the hydration reaction of the calcium silicate-based material, thereby deteriorating the solidification performance thereof. At present, the field mainly uses an organic-inorganic composite strengthening strategy to solve the defects of the method.
CN202111263723.7 discloses an anti-collapsibility silicon-calcium-based root canal filling paste, a preparation method and application thereof, wherein the root canal filling paste takes a silicon-calcium-based compound and calcium formate as solid phases, and a konjac gum solution as a liquid phase, wherein the hydration acceleration effect of the calcium formate and the konjac gum binding effect effectively improve the anti-collapsibility and the solidification characteristic of the silicon-calcium-based material. However, calcium formate itself has no gelling property and cannot be cured by itself, and in addition, konjak gum can form a liquid phase with high viscosity at a lower concentration, and mixing and stirring of the solid phase and the liquid phase are difficult at a slightly higher concentration.
In addition, CN200710047442.1 discloses an in-situ self-curing bioactive material for filling human bone defect and a preparation method thereof, wherein the material takes calcium phosphate and tricalcium silicate as composite powder to prepare the bone repair material with self-curing property, although the solid phase powder of the material relates to calcium phosphate with self-curing gelation property, the calcium phosphate is a complex system with various curing properties, and the curing mechanism and curing behavior of different component combinations are greatly different. In addition, the material is not related to solving the problem of insufficient anti-collapsibility of the calcium silicate-based material.
CN103007340a discloses a self-curing composite bone repairing material for repairing hard tissue of human body and its application, said bone repairing material contains solid phase of tricalcium silicate and calcium phosphate bone cement, and several inorganic substances of monobasic potassium phosphate and magnesium oxide, and its liquid phase contains potassium citrate and chitosan. Although the bone repair material has a short curing time, because the material contains various gelling systems with curing characteristics such as a calcium silicate base, a calcium phosphate, a magnesium phosphate and the like, and the binding performance of organic matters in a liquid phase is insufficient, the material has poor collapsibility, injection performance and operation performance.
When used in root tip induction forming, root tip barrier, root canal filling and other treatments, the dental material with excellent osteogenesis inducing property is favorable for eliminating inflammation of periapical and periodontal membrane, stimulating cementation of root tip, promoting the continuous growth and development of root, and promoting regeneration of bone defect parts such as alveolar bone. For these reasons, there is a strong need in the art of dental pulp therapy to develop a calcium silicate-based bioactive paste material that has good solidifying properties, is injectable, is resistant to collapsibility, and has high osteogenic activity.
However, there has been no report so far on the synergistic use of α -tricalcium phosphate type self-curing material with hydroxypropyl methylcellulose to improve the handleability, collapsibility and osteogenic activity of the calcium silicate-based paste.

The following performance characterization was performed for each example and comparative example:
injectability determination: the prepared paste material was loaded into a syringe, and then placed in a universal tester to determine the variation of its injection force and displacement, and the injectability, expressed as the weight of paste injected as a percentage of the total weight of the raw paste, was expressed by measuring the weight of the paste before and after injection.
The injection performance test of comparative examples 1-2 and examples 1-6 showed that the paste of comparative example 1 had a gritty feel, low inter-particle viscosity, difficulty in injection, and severe pressure filtration phenomenon, whereas the paste of comparative example 2 had an injectability of 93%, showing excellent injectability, and the results showed that the incorporation of hydroxypropyl methylcellulose in the paste slurry could improve injectability. As can be seen from fig. 1, the injection force required for the pastes of examples 1-3 is significantly reduced compared to comparative example 2, i.e., the pastes are easier to inject and have better injectability, which results indicate that the injectability can be enhanced after the incorporation of the α -tricalcium phosphate self-curing material into the paste. In addition, the pastes of examples 4, 5 and 6 were easy to inject, and had excellent injectability.
Determination of anti-collapsibility: the blended paste material was placed in a syringe, and injected into a water glass dish, and after shaking in a shaker for 10 minutes, the free collapse of the paste particles was observed.
As a result of the anti-collapse property test of comparative examples 1 to 2 and examples 1 to 6, as shown in FIG. 2, the paste of comparative example 1 was exposed to water to cause a particle release phenomenon, and after shaking for 10 minutes, the paste was not collapsed and the particles were scattered over the entire liquid surface. In contrast, in comparative example 2, no particle release phenomenon occurred before and after vibration of the paste, and excellent anti-collapse properties were exhibited. Similarly, the pastes of examples 1-3 maintained the original slurry shape after vibration, without particle collapse. From the above results, it is clear that hydroxypropyl methylcellulose and α -tricalcium phosphate effectively improve the anti-collapse ability of the paste material. In addition, as can be seen from fig. 3, the pastes of examples 4 to 6 all maintained the initial injection shape after vibration, and the particles in the slurry did not collapse and leak, showing excellent anti-collapse properties.
Curing time measurement: the freshly prepared paste material was placed into a mold, and then placed into an environment at 37 ℃ for curing, and the curing time of the paste was measured by a vicat.
The results of the tests conducted in examples 1 and 3 and comparative example 2, as shown in FIG. 4, show that the initial setting and final setting times of the paste in comparative example 2 are 79 and 190 minutes, respectively, and the initial setting and final setting times of the paste in example 1 are 64 and 182 minutes, respectively, and the paste setting time is shortened, and the results indicate that the introduction of 10% α -tricalcium phosphate into the paste can accelerate the hardening of the paste, and that the paste setting time is prolonged when the α -tricalcium phosphate content is further increased to 50%.
Alkaline formation ability test: placing the newly prepared paste material into a mold, curing at 37deg.C to obtain a cured product, soaking the sample in Tris-HCl solution (pH=7.4, 37deg.C) to obtain a ratio of surface area of the sample to volume of Tris-HCl solution of 0.1cm 2 /mL. After soaking for different time, the solution of the soaked sample is measured by a pH meterIs a pH value of (c).
As shown in FIG. 5, the test results of examples 1-3 show that after the sample is soaked for 1 day, tris-HCl solution can be alkaline, the pH is up to 8.97, when the soaking time is longer than 5 days, the pH of the Tris-HCl solution after all the samples are soaked exceeds 10, the strong alkaline forming capability is shown, and a certain sterilization effect can be shown in an environment with the pH being greater than 9.
Cell activity and osteogenic gene expression test: grinding the cured paste sample into fine powder, adding the powder into a DMEM (Hyclone, USA) cell culture medium for leaching, and centrifugally collecting supernatant to obtain a sample leaching solution for subsequent testing. The osteoblast (ATCC) is taken as an experimental cell, the cell activity of different pastes is evaluated by a cell Counting Kit (Counting Kit-8, CCK-8, beyotidme, china), firstly, the osteoblast is added into a DMEM culture medium containing the prepared dental paste extract for culture, then the CCK-8 reagent is added, the incubation is carried out at 37 ℃ in a dark place, and then the OD value at 450nm is measured by an enzyme-labeling instrument.
Cell viability (%) = sample group corrected OD value/control group corrected OD value x 100%.
And detecting the influence of different samples on the expression conditions of the osteogenic related genes ALP and OPN in the cells by using an RT-PCR test method. Osteoblasts were cultured in a medium containing the sample extract, then total RNA was extracted with an RNA kit (Omega, china), and the obtained RNA was converted into cDNA using a reverse transcription kit (Takara, japan). Finally, the expression of ALP and OPN osteogenesis-related genes was detected by quantitative real-time reverse transcription polymerase chain reaction (PCR apparatus, bio-Rad, USA), and the sequences of the synthesized primer genes were as shown in Table 1, with GAPDH as a reference.
PCR reaction procedure: 10. Mu.L of the reaction system contained PSYBR Premix Ex Taq II (2X) 5. Mu.L, 0.4. Mu.L each of the forward and reverse primers, 1. Mu.L of RT reaction solution (cDNA solution), dH 2 O (sterilized distilled water) 4.2. Mu.L was added to the eight-way tube.

ALP and OPN gene expression is shown in FIGS. 7 and 8, wherein the paste extract solutions of examples 1-3 were effective in up-regulating ALP and OPN gene expression, showing excellent bone-promoting ability.
