Background

Conventional methods of tooth restoration have many limitations. For example, many animal dental restoration procedures involve expensive, stressful, and dangerous surgical procedures. Other dental restorative procedures require biomineralization and remineralization, which takes a long time to become effective. Methods of addressing tooth discoloration also have many limitations, such as potential damage to enamel. Therefore, alternative materials and methods are needed to restore and whiten teeth. Many embodiments of the present disclosure address the above-mentioned needs.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the subject matter claimed. In this application, the use of the singular includes the plural, the words "a" or "an" mean "at least one" and the use of the word "or" means "and/or" unless specifically stated otherwise. Furthermore, the use of the term "including" as well as other forms, such as "includes" and "including," is not limiting. Meanwhile, unless specifically stated otherwise, terms such as "element" or "component" include an element or component of one unit and an element or component including more than one unit.

The section headings used herein are for organizational purposes and are not to be construed as limiting the subject matter described. All documents, or portions of documents, cited in this application, including but not limited to patents, patent applications, articles, books, and treaties, are hereby incorporated by reference in their entirety for any purpose. The definition of a term in one or more of the incorporated documents and similar materials is to be contrasted with the definition of that term in the present application, which controls the present application.

Enamel is the hardest, most dense structure in the body. Tooth enamel is capable of grinding food prior to swallowing it, protecting the interior of the teeth from normal oral bacteria and other harmful oral substances.

Dental damage is a major health threat and may deteriorate quality of life. In extreme cases, tooth damage can be life threatening. Although teeth are the hardest tissues of the body, they are still subject to mechanical wear and acid erosion. Untreated, these lesions may lead to tooth loss or infection.

Furthermore, when the enamel layer is removed, sensitive dentin is exposed to environmental factors. This in turn can lead to toothache and infection.

Reasons for dentin exposure or enamel layer rupture include, but are not limited to: trauma, periapical inflammation, dysplasia of enamel, dysplasia (dysplasia), hypermineralization, genetic diseases (such as incomplete starch formation or incomplete dentinal development) or dental diseases. In fact, dental disease has been a ubiquitous disease in dogs and cats.

In animals such as dogs, extensive chewing is closely associated with dental damage. In fact, dogs have a much thinner enamel layer than humans and are therefore more prone to excessive wear. This wear in turn can result in exposure of dentin and pulp, causing pain. For example, american pet owners report that the process of correcting teeth is very painful, and that about 92% of the cases require administration of pain killers.

Conventional dental restoration procedures involve surgery to apply a restorative material. However, this procedure can be costly and stressful. In addition, the restorative material may cause occlusal wear of the treated teeth.

In addition, general anesthesia is often required for dental restoration or repair of damaged enamel in veterinary medicine. However, administration of general anesthesia can subject the animal to anesthesia-related deaths, causing emotional and economic problems for the owner of the animal.

An alternative to the currently used process of tooth restoration is remineralization of damaged enamel. In particular, the biomineralization process is used to apply hydroxyapatite nanoparticles to teeth and form hard enamel tissue in vitro or in vivo. Other remineralizing precursors include casein phosphopeptide stabilized amorphous calcium phosphate, fluoride containing amelogenin and Hydroxyapatite (HAP) containing polydopamine. Unlike conventional dental treatments, the above-described method can restore teeth with almost the same material as the teeth themselves.

However, the biomineralization and remineralization processes take a long time to be effective. This presents a significant challenge for clinical application of this extended procedure, as it is often not matched to the rate of tooth wear. Furthermore, many materials used in biomineralization and remineralization processes are not resistant to high bite forces, especially when chewing hard materials.

Another problem associated with teeth is tooth discoloration. Dentists and individuals use a number of materials and methods to whiten teeth. However, many of the above materials and methods are detrimental to enamel and tooth health. Adverse reactions associated with these materials and methods include: tooth sensitivity, gingival or mucosal irritation, enamel or dentin oxidation, restorative material destruction, reduced shear and tensile bond strength, localized inflammation, and tooth sensitivity (tooth sensitivity).

Therefore, alternative materials and methods are needed to restore and whiten teeth. Many embodiments of the present disclosure address the above-mentioned needs.

In some embodiments, the present disclosure relates to methods of modifying teeth. In some embodiments illustrated in fig. 1A, the methods of the present disclosure comprise: an object is applied to the teeth, the object comprising a tooth-altering composition (step 10). The composition is then released from the object onto the teeth (step 12). The composition may have various tooth-altering effects including: tooth whitening (step 16), tooth restoration (step 17), and tooth maintenance (step 18).

Other embodiments of the present disclosure relate to objects comprising a tooth-altering composition. In some embodiments, shown in fig. 1B, an object of the present disclosure comprises: an object 20 comprising a tooth-altering composition 22, the composition being released from the object 20 onto the teeth. The composition 22 may have various dental modifying effects including: tooth whitening, tooth restoration and tooth maintenance.

As set forth in greater detail herein, the methods and objects of the present disclosure can have many embodiments. In particular, various objects and various compositions can be applied to various teeth in various ways to have various tooth-modifying effects.

Reference will now be made to more specific embodiments of the disclosure, and experimental results that provide support for such embodiments. Applicants, however, point out that the following disclosure is for illustrative purposes only and is not intended to limit the scope of the claimed subject matter in any way.

Example 1: nanomaterial for restoration of teeth

In this example, applicants have demonstrated that various ingredients are effective in restoring teeth. Applicants' previous studies found that alpha-zirconium phosphate (alpha-ZrP) is an effective additive for forming tribofilms (Dai et al, Lubricants (Lubricants), 2016, 4(3), 28; Xiao et al, appl. Surf. Sci.2015,329, 384-389; He et al, Colloids Surf. physiochem. Eng. Asp.2014,452, 32-38; Chen et al, J. Tribol.2018,141 (3)). In particular, applicants have found that the α -zirconium phosphate nanoparticles have a unique layered structure. In addition, van der waals forces exist between the layers that hold the layers together. Under shear, these particles flake off, resulting in low friction.

The chemical reaction between the particle and the surface is triggered by mechanical forces. To date, no report has been made on restoration or surface modification of teeth using the concept of a rubbing film. In this example, applicants report a new method of using functionalized nanoparticles to repair, modify and protect dental enamel. The inspiration of this new approach comes from the effectiveness of tribochemical interactions between the rubbing surfaces. Applicants designed dental restorative materials by forming tribofilms and nanoparticle polymer biomineralization. The results show that a solid film of phosphorus mineral was successfully rubbed onto the abraded teeth to a thickness of up to 1 μm. The film is also effective in filling cracks in the tooth surface and improving surface integrity.

Example 1.1. materials

All inorganic reagents used in this example were purchased from Sigma Aldrich (Sigma Aldrich). The organic amine M-600 used in this study was supplied by Henschel Corporation (Huntsman Corporation). The synthesis of the materials in this study employed the following steps. alpha-ZrP nano-particles and HAP nano-particles are synthesized by a hydrothermal method. For alpha-ZrP, 50ml of food grade 12M phosphoric acid and 5g of zirconium chloride octahydrate (ZrOCl) were mixed under constant stirring2·8H2O). The mixture was then sealed in a PTFE lined autoclave and transferred to a 200 ℃ oven for 24 hours.

The HAP precursor was prepared using the following procedure: under constant stirring and 50-60 deg.C, 12 ml of 0.25M calcium nitrate solution (Ca (NO)3)2) Added dropwise to 20 ml of 0.15M disodium hydrogen phosphate (Na)2HPO4) In solution. The pH of the mixture was then adjusted to 8-10 with ammonium hydroxide. The mixture was then placed in a PTFE lined autoclave and placed in an oven at 160 ℃ for 12 hours. After the hydrothermal reaction, the product was washed with deionized water and recovered by centrifugation three times.

The washed nanoparticles were dried in a vacuum oven at 70 ℃ for 12 hours. The synthesized alpha-ZrP is inserted with polyetheramine M-600. The synthesized 1mmol α -ZrP was first dispersed in 5ml deionized water for 1 hour with an ultrasonic bath. Next, a 0.4M-600 solution was added dropwise to the dispersion.

The friction repair paste is a mixture of HAP nanoparticles and M-600 amine intercalated α -ZrP. First, the synthesized intercalated alpha-ZrP dispersion is mixed with HAP nanoparticles. The mass ratios of HAP nanoparticles to α -ZrP used before intercalation were 0:1, 0.25:1, and 0.5:1 (the resulting repair agents were labeled S0, S2.5, and S5, respectively). The product was centrifuged for 10 min. After the centrifugation process, the supernatant was removed by tilting the tube, and the precipitate was recovered. These precipitates are then used in the frictional chewing process described below.

The canine teeth were from Texas A for all dogs&M veterinary medical teaching Hospital (Texas A)&M veterinary media mining hospital). Before the experiment, hydrogen peroxide (H) was used2O2) And deionized water to clean the teeth. The remaining soft tissue was removed with a knife.

The "disc" samples were prepared from canine teeth for the experiments. To make the sample, the canine teeth were first sealed in an epoxy pan with the distal surface facing upward. Then, the enamel of the surface was carefully exposed, sanded, and polished with diamond gypsum of 3 μm size.

Bovine bone grinders were used to simulate the chewing process when eating hard foods. The split bovine femoral bones (beef split femur bone) were cooked in an autoclave for 4 hours and air dried. The cooked bone was then ground with a mortar and pestle and then mixed with deionized water at a 1:1 mass ratio.

Example 1.2 Experimental protocol

To simulate the chewing and grinding motion of the teeth, a friction chewing process is employed. This process was carried out on a pin-on-disc tribometer (CSM instruments). The setup for the friction chewing experiment is shown in figure 2. Two dog teeth were used in this setup. One of the teeth acts as a pin and the other acts as a disk. The normal force on the pin is 1N. The pin teeth do sinusoidal reciprocating motion on the disc teeth, the amplitude is 2mm, and the maximum speed is 1 cm/s.

Prior to the frictional chewing process, a restorative is placed between the teeth friction pair (tooth triboair). The movement was terminated after 100 cycles. After this process, the sample was rinsed with deionized water and air dried.

Scratch tests were then performed on the samples to qualitatively evaluate the mechanical properties of the films. The scratch test uses the same tribometer with a steel needle. The needle was pressed against the fluted disc sample with a force of 1N and manually stroked across the formed tribofilm.

The effect of the repair agent was characterized after tribofilm deposition. The morphology and microstructure of the tribofilm formed were characterized by the interferometer (Zygo NewView 600, Zygo Corp.) and AFM (Nano-R2, Pacific Nanotechnology) in close contact mode. The raman spectra of the rubbed film were collected using an iHR550 spectrometer (HORIBA Scientific, Edison, NJ) with a 532nm laser. Two spectra were collected, one from the rubbing film and the other from the polished tooth surface.

The pin teeth that underwent the frictional chewing process were analyzed using synchrotron radiation micro X-ray CT (μ -XCT). These experiments were carried out on the Beam line 8.3.2 instrument of the Lawrence Berkeley National Laboratory. All samples were imaged using a LuAG: Ce scintillation counter. Tomographic reconstruction was performed using the Xi CAM and tomopy tomographic insert.

Imaging of the coating is accomplished by a dual energy k-edge technique. Prior to testing, the illumination x-ray energy was calibrated to the x-ray absorption edge of Zr using a pure α -ZrP nanoparticle sample. As shown in fig. 3, the absorption of x-rays by zirconium element jumps around 18 KeV. Two separate tomographic images of the same sample were taken using two illumination energies: 18.2KeV and 17.8 KeV.

As shown in FIG. 3, the Zr element was brighter when the sample was irradiated with 17.8KeV than when the sample was irradiated with 18.2 KeV. Thus, the difference between the two data sets can reveal the distribution of the Zr element, i.e., the distribution of applicants' repair tribofilm. Data collected from the experiments were then presented using Avizo software.

Example 1.3 results and discussion

The enamel wears as the tooth sample undergoes the abrasive chewing process with the simulated food. Interferometer images of the wear track are shown in fig. 4A-B. Within the wear track, the enamel rod protrudes. It appears that the soft tissue is removed by abrasion of the bone grind particles. Despite having a similar chemical composition (HAP), bone grinders cannot attach to the enamel surface by this process.

All of the restoratives formed a tribofilm after the tribological chewing process. An interferometer topographic image is shown in FIGS. 5A-D. The films shown centrally in fig. 5A-D are the result of a rubbing chewing process using a restorative.

Without the additive, friction pin-disc wear would result in the disc surface being grooved. But instead a thin film with a thickness in the range of 100nm to 1 μm is produced here. The pressure range at which the membrane is produced is calculated to be 100 MPa. The creation of such a film prevents wear of the teeth.

The thickness and coverage of the tribofilm can be controlled by the amount of HAP nanoparticles. As the amount of HAP used increases, the thickness of the resulting friction film increases. The film thickness was only about 100nm using the repair agent S0, but in the case of S10, when the HAP: ZrP mass ratio was increased to 1:1, the film thickness was increased to 2 μm. This mass ratio also changes the coverage of the tribofilm.

In the case of S0, a continuous film was produced, and samples S2.5 and S5 were also able to produce a tribofilm that almost completely covered the wear track. Further, when the mass ratio of ZrP and HAP is increased to 1:2, a tribofilm cannot be formed at all. Too much HAP nanoparticles added can also cause the repair agent to lose its tribo-filming properties. Thus, applicants believe that S5 is a good compromise between film coverage and film thickness.

As shown in fig. 6A-D, Atomic Force Microscope (AFM) images show the microstructure of the intercalated α -ZrP tribofilm. The AFM height map and phase map of the tribofilm are shown in fig. 5A and 5C. The tribofilm produced by S0 consisted of a number of plate-like particles with a size of about 200nm (FIGS. 6A-B). The results show that the deposition is not a direct deposition of ZrP particles with a size of about 1 μm. The ZrP layer is more easily exfoliated by shear forces during friction chewing, since the intercalation process reduces van der waals forces between the ZrP layers. The exfoliated and functionalized two-dimensional flakes thus become building blocks of the tribofilm.

The addition of HAP nanoparticles changes the microstructure of the resulting tribofilm. A more regular cellular structure is formed (fig. 6C-D), rather than a platelet-like aggregation of particles. The cellular structure consists of particles (most likely HAP nanoparticles) of almost the same size. HAP nanoparticles survived the abrasive chewing process and were adhered together by M600 attached to ZrP.

The above results further explain why the addition of HAP nanoparticles increases the thickness of the film, but decreases the coverage. In this example, HAP cannot form a tribofilm if no α -ZrP is intercalated. Thus, the higher the HAP concentration, the less likely the intercalated α -ZrP will be in contact with the tooth surface.

The resulting film does not introduce any foreign inorganic functional groups on the tooth surface. It is well known that tribochemical processes chemically alter phosphate groups. Raman spectroscopy results showed only two peaks for enamel and tribofilm (figure 7). Two peaks are from-PO4A group. No other chemical species were detected in the raman spectrum.

To characterize the restorative ability of the restorative agent to the entire tooth, not just the surface, micro X-ray CT was used. As shown in fig. 10A-B, the density distribution of the Zr element was overlaid on the reconstructed tooth image. After the frictional chewing process using the S5 reagent, the teeth were the tips of needle-shaped canine teeth. In this example, a tooth with a crack at its tip was selected. In the contact area, a film is formed which wraps around the tip of the tooth. Further, the applicant found that Zr element appears inside the tip crack.

Based on the above results, the applicant proposed a mechanism for friction film formation of the pure intercalated α -ZrP dental restorative in this example. The nanoparticles are exfoliated and disintegrated by the abrasive mechanical forces. Thereafter, the polymer chains attached to the exfoliated nanoparticles reattach to those exfoliated layers under shear.

The polymerization process may occur when the polymer chains are ground under mechanical force. This mechanochemical polymerization process may be the driving force for tribofilm growth.

When HAP nanoparticles are introduced, the polymer chains further interact with the HAP crystals and adhere to the HAP crystals on the tooth surface, thereby forming a thick coherent tooth restoration friction film. In the scratch test, the scratch resistance of the resulting film was equal to or higher than the performance of the tooth itself (fig. 9A-B). Steel needle scraping results in material loss from the tooth surface and tribofilm surface. However, despite the scratch, the tribofilm was not removed or peeled off from the sample surface. The tribofilm exhibits good hardness and wear resistance compared to deep grooves on the unprotected enamel surface.

EXAMPLE 1.4 conclusion

In this embodiment, applicants provide a simple one-step method to restore and maintain the teeth of humans and pets. Repairing and forming a protective film is made possible by mechanical friction (chewing) of a material consisting of nanoparticles, polymers and biomineralization materials. After simulating frictional chewing between two teeth, the tooth restoration agent can form a friction film with a thickness of up to 2 μm. The repair film formed had a hardness comparable to the enamel surface. In addition to surface restoration, the new agents can also enter cracks in the enamel surface.

Furthermore, applicants have found that polyether modified nanoparticles can induce the formation of tribofilms in aqueous solutions. The formation of this protective film may be attributed to the affinity between polyethers and HAPs within the tooth enamel.

Example 2: composition for self-restoration of teeth

In this embodiment, applicants provide a chewable object comprising a composition associated with the chewable object, wherein the composition is released onto the teeth when the chewable object is chewed. In this example, the composition is an aqueous paste of HAP nanoparticles and M-600 amine intercalated ZrP nanoparticles. In this embodiment, applicants further provide a method of applying a material to a tooth, comprising: chewing a chewable object comprising a composition that is released onto teeth when the chewable object is chewed.

This example describes the design and fabrication of nanomaterials which can heal the wear points on the teeth by chewing. The self-repairing or self-protecting function is based on the mechanical catalysis, tribochemical or mechanochemical properties of the nano material. Self-restoration of teeth can be achieved by chewing to initiate a chemical reaction between the nanoparticles, enamel, bone and the calcium-containing compound. During chewing, a thick coating that is strong, durable and highly abrasion resistant can be produced without any subsequent steps (such as shaping, grinding or polishing).

As shown in fig. 10A-B, canines were repaired by rubbing the composition of the present disclosure for several minutes. The image was obtained by microscopic tomography and the orange color was a trace of zirconium in the film. The element penetrated cracks and grooves in the canine teeth and uniformly covered them.

The repair film is durable and scratch resistant. Fig. 11A-B show images of the morphology of the canine teeth after the restoration. The rubbing direction was performed by applying up and down. The surface is formed by friction. Thereafter, a scratch test was performed in the rubbed area. The scratch test showed that the bare teeth were scratched while the film remained in place.

Fig. 12A-B show the generation of a prosthetic film on the canine teeth. Red indicates high surface area. Fig. 13 shows the curves of the canine teeth. Fig. 14A-B show that scratching does not remove the film. Figure 15 shows the creation of a prosthetic film on a human tooth. Fig. 16 shows the area covered by the film. Fig. 17 shows that scratching does not remove the film. Fig. 18 shows a film image built on a tooth. Figure 19 shows a proposed material with better wear resistance and hardness.
