For example, if a particular element or component in a composition or article is said to have 5 wt. %, it is understood that this percentage is in relation to a total compositional percentage of 100 wt. %.
(45) Aspects of the present disclosure are directed to biodegradable dental gum comprising organic sources, including date seed, black palm seed, corn, olive seed, fish bone, oyster shell, coconut shell-based nano-starch, and sheep bone powder. The subject matter discussed herein provides using biodegradable materials to form a moldable composition, and the dental gums prepared from this moldable composition. The formed organic dental gum pad obtained has increased mechanical strength, durability, and aesthetic appearance making it a superior option to traditionally manufactured dental gum pads.
(46) According to an aspect of the present disclosure, an organic dental gum pad formed from a moldable composition is described. In some embodiments, the organic dental gum pad comprises a nanostarch-based biomaterial.

In a specific embodiment, the nanocomponent comprises bio-based materials of plant and animal origin. In a specific embodiment, the nanocomponent comprises at least one selected from a group consisting of fish bone powder, oyster shell powder, coconut shell powder, and sheep bone powder. Fish bone, oyster shell, and sheep bone may serve as useful components of the organic dental gum pad due to their inclusion of hydroxyapatite.
(48) Hydroxyapatite may be important in dental implants, such as dental gum pads, because it may aid in the integration of the dental gum pad with the surrounding bone, leading to faster healing and a stronger bond in a mouth of a subject. Hydroxyapatite may, therefore, aid in increasing the success rate of a dental implant by facilitating osseointegration (i.e., bone growth around the implant) due to its similar composition to natural bone mineral. Moreover, because hydroxyapatite is naturally found in teeth and bones, it is well-tolerated by the body, minimizing the risk of rejection when a dental implant is placed.

(54) In one embodiment, the nanocomponent comprises graphene. Graphene may improve the integration of a dental implant with the surrounding bone tissue by promoting the differentiation of mesenchymal cells into osteoblasts, which lay down new bone matrix. Further, graphene may help reduce microbial adhesion and risk of complications derived from bacterial infections, such as peri-implantitis and dental caries, upon placement of the dental gum pad. Graphene may also aid in the reduction of inflammation and promote tissue regeneration, which can lead to better healing and more aesthetically pleasing results when the dental gum pad is placed in a mouth of a subject. Incorporation of graphene into the dental gum pad may also help increase the longevity of the implant due to graphene's slow oxidation, decreasing the need for frequent replacement of the dental gum pad. In an embodiment, the graphene may be at least one selected from the group consisting of graphene oxide, graphene quantum dots, graphene nanoparticles, reduced graphene oxide, chemical vapor deposition (CVD) graphene, and/or combinations thereof.

Further, starch and cellulose may aid in improving mechanical properties of the dental gum pad, particularly when combined with hydroxyapatite. When combined with hydroxyapatite, starch and cellulose may help bind the materials of the dental gum pad together, creating a more stable dental gum pad with increased biomechanical strength. Starch and cellulose are also tolerated well by the human body, minimizing the risk of rejection when the dental gum pad is placed within the mouth of a subject.

(63) In some embodiments, the organic composition comprises waste jackfruit latex from jackfruit trees (Artocarpus heterophyllus). Jackfruit trees can be found in tropical areas including Thailand. Waste jackfruit latex is a sticky, white, milky latex that is excreted by jackfruit trees. Waste jackfruit latex is in the form of an aqueous emulsion and comprises many ingredients including, but not limited to, lipids, rubbers, and resins. Waste jackfruit latex can be used as a adhesive or as a natural replacement for synthetic resins, aiding in the production of the disclosed the curable organic moldable composition having increased mechanical strength to form the dental implant pad. Further, waste jackfruit latex has antimicrobial properties, making it a useful addition in dental gum pads, to help avoid complications caused by bacterial infections.

(64) In some embodiments, the organic composition comprises a natural glue. In some embodiments, the organic composition comprises a Lannea sp. glue. Trees of the Lannea genus are found in tropical areas and produce a sap that is sticky due to the presence of sugars produced by photosynthesis, similar to other tree saps. Lannea sp glue may aid in creating a dental gum pad having increased mechanical strength and curing properties, while also providing an organic alternative to synthetic adhesives and resins that are often utilized in other dental implants. In one embodiment, the organic composition comprises a Lannea sp. glue in an amount of 1 to 10 wt. % relative to a total weight of the organic composition, preferably 2 to 9 wt. %, preferably 3 to 8 wt. %, preferably 3 to 7 wt. %, preferably 3 to 6 wt. %, preferably 3 to 5 wt. %, preferably 3 to 4 wt. %, most preferably 3 wt. % relative to a total weight of the organic composition. In some embodiments, the organic composition comprises Acacia nilotica glue. Acacia nilotica (Babul tree) is a gum-yielding Acacia species found in the Indian subcontinent. Acacia nilotica glue may aid in creating a dental gum pad having increased mechanical strength, while providing an organic alternative to synthetic adhesives often utilized in other dental implants. Moreover, Acacia nilotica glue has antimicrobial, antioxidant, and anti-inflammatory properties, making it a suitable additive to maintain tooth mineralization and avoid dental caries. Acacia nilotica glue may also help increase the longevity of the implant due to the compounds increase antioxidant and antimicrobial properties, decreasing the need for frequent replacement of the dental gum pad.

(65) In some embodiments, the organic composition comprises sheep gut oil-based glycerin. Glycerin can be obtained from animal fat, such as pork fat beef fat, sheep fat, and the like. In an embodiment, the glycerin is obtained from sheep gut, particularly sheep gut oil. Glycerin is highly soluble in water and enhances the degradability of a polymer when added as a plasticizing agent. Further, when a curable composition is cured, oxygen in the air may cause an interference in the polymerization resulting in the formation of an oxygen inhibition layer on the surface of the composition. The oxygen-inhibited layer may then result in a sticky, resin-rich uncured layer that is left on the surface of the composition.

In one embodiment, the molded structure is cured via photocuring or thermal curing to form the dental crown. Thermal curing is the process of temperature-induced chemical change in a material, such as the polymerization of a thermoset resin.

EXAMPLES
(80) The following examples illustrate an organic dental gum pad. The examples are provided solely for illustration and are not to be construed as limitations of the present disclosure, as many variations thereof are possible without departing from the spirit and scope of the present disclosure.
Example 1: PH and Starch Determination
(81) The pH and cellulose content of the starch of the organic dental gum pad of the present disclosure were determined, and their values were compared to those of surgical synthetic dental gums available in the market. The quantitative determination of starch was carried out using methods known in the art. The results of this study are depicted in Table 1.

Example 2: Nanostarch and Nanocellulose Measurement
(83) The particle size of the nanostarch and nanocellulose was measured by Scanning Electron Microscopy (SEM), and the results indicate that the nanoparticle size of the moldable composition forming the organic dental gum pad was 18 nm. In comparison, the nanoparticle size range for standard synthetic dental gums typically falls between 1 and 100 nm. This illustrates that the moldable composition forming the organic dental gum pad of the present disclosure has a finer particle size, allowing for the enhancement of the tensile strength, an increase in the flexural strength, a high fracture toughness, and an increase in the shear bond strength of the organic dental gum pad.

Example 3: Absorption Test (as ASTM D570)
(85) The dental gum pad prepared was further evaluated for its ability to absorb moisture. The tests to determine water absorption were carried out in accordance with ASTM D570. The purpose of ASTM D570 is to determine the rate of water absorption by immersing the specimen in water for a specific period. In this test, the dental gum pad absorbed 0.03% water. Water absorption was calculated by determining the percentage increase in weight of the sample following the experiment to characterize this attribute. The results of this study are depicted in Table 3. It can be observed that the water absorption for the dental gum pad prepared by the present disclosure is very low compared to surgical dental gum, illustrating their water-resistant property which may provide for a more stable and durable dental gum pad.
