The Anti-Inflammatory Effect of Nigella sativa Toothpaste on Porphyromonas gingivalis Bacteria Through Decreased TNF-α, MMP-9, PGE-2 Expression in Wistar Rats.

OBJECTIVE: The main principle in preventing periodontal disease is to improve oral hygiene. The bacteria that cause the onset of periodontal disease, one of which is the Porphyromonas gingivalis bacterium, causes inflammation. Persistent inflammation causes tissue damage and alveolar bone resorption by secreting proinflammatory cytokines, matrix metalloproteinase-9 (MMP-9), prostaglandin E2 (PGE-2), and anti-inflammatory cytokines. In this case, preventive treatment is needed, such as using toothpaste that contains anti-inflammatories so that the progression of the disease does not get worse. The traditional ingredient currently being developed is Nigella sativa, which has anti-inflammatory properties. Therefore, this study analyzes the potential of toothpaste containing Nigella sativa on the expression of tumor necrosis factor-α (TNF-α), MMP-9, and PGE-2 in the Wistar rat model induced by Porphyromonas gingivalis bacteria. This study aims to prove the potential of Nigella sativa toothpaste to decrease the expression of PGE-2, TNF-α, and MMP-9 in the gingiva of rats induced by Porphyromonas gingivalis bacteria. MATERIALS AND METHODS: Forty-five healthy male Wistar rats were used, consisting of the negative control group, which was only injected with Porphyromonas gingivalis bacteria ATCC3322. The positive control group was given enzyme toothpaste, and the treatment group was assigned 1 mg of Nigella sativa paste using a microbrush for 30 seconds on the gingiva incisors mandibular with a circular motion, given two times a day for a week. Immunohistochemical to see the expression of TNF-α, PGE-2, and MMP-9. Parametric comparative analysis using a one-way analysis of variance test was performed to analyze differences between groups. RESULTS AND DISCUSSION: Nigella sativa toothpaste significantly reduced proinflammatory cytokines, as seen through the expression of TNF-α, PGE-2, and MMP-9 on days 3, 5, and 7 (p <0.05). CONCLUSION: In the limit of studied animal model, this trial indicates that giving toothpaste with black seed extract (Nigella sativa) could inhibit inflammatory mediators, as seen from the decreased expression of MMP-9, TNF-α, and PGE-2 seen from the 3rd, 5th, and 7th days.

Inhibiting the growth of periopathogenic bacteria and accelerating bone repair processes by using robusta coffee bean extract.

Background: Periodontitis is an inflammatory disease of the teeth-supporting tissues caused by microorganisms. Robusta coffee bean extract has antibacterial properties due to its caffeine, flavonoids, trigonelline, and chlorogenic acid contents. The robusta coffee bean extract also regulates alveolar bone healing through bone remodelling. Aim: The study aimed to investigate robusta coffee bean extract to inhibit bacterial growth and accelerate bone repair in vitro and in vivo. Methods: This study used the paper disc diffusion method with the research group of robusta coffee bean extract with concentrations of 50%, 25%, 12.5%, 6.25%, and negative control, as much as 20 and dripped onto the disc paper then placed on the surface of the agar media that had been inoculated with bacteria. The diameter of the inhibition zone was measured. Twenty periodontitis rat models were given 0.05 ml of the robusta coffee bean extract on the molars and put in a periodontal pocket for seven days. Rats were decapitated, and alveolar bone tissues were stained with HE and IHC staining. The number of osteoclasts, osteoblasts and BMP-2 was counted using a microscope. Statistical test with Kruskal Wallis followed by Mann Whitney showed a p-value of <0.05. Results: The average diameter of the inhibitory zone of robusta coffee bean extract showed that the P. gingivalis group of bacteria was higher than that of A. actinomycetemscomitans and S. viridans (p < 0.05) with a concentration of 50%. The average number of osteoblast cells increased, and the average number of osteoclast cells decreased in the 50% concentration group compared to the other groups (p < 0.05). BMP-2 expression in the robusta coffee bean extract group was 50% higher than in the other groups. Conclusion: Robusta coffee bean extract has a periopathogenic antibacterial and accelerates alveolar bone repair.

Accelerating Wound Healing of Traumatic Ulcer with Topical Application of Dental Pulp Mesenchymal Stem Cell Secretome and Robusta Green Coffee Bean Extract Combination in vivo

ABSTRACT Objective: To investigate the ability of a combination dental pulp mesenchymal stem cell secretome (DPMSCS), robusta green coffee bean extract (RGCBE), and Carboxymethylcellulose-Natrium (CMC-Na) in a Wistar rats model of traumatic ulcers. Material and Methods: Twenty-eight young, male, healthy Wistar rats (Rattus norvegicus) were divided into seven groups randomly: Group K0, group K1-3 (traumatic ulcer rats that received CMC-Na gel for three days), group K1-7 (traumatic ulcer rats that received CMC-Na gel for seven days), group K2-3 (traumatic ulcer rats that received RGCBE for three days), group K2-7 (traumatic ulcer rats that received RGCBE for seven days), group K3-3 (traumatic ulcer rats that received DPMSCS for three days), and group K3-7 (traumatic ulcer rats that received DPMSCS for seven days). An ulcer was made with an amalgam stopper on the right buccal mucosa of the rats. DPMSCS 50% gel was applied to the ulcer on the left buccal mucosa. The ulcer diameter was measured on day 3 and day 7. Results: There was a significant difference in the diameter of the ulcer, the number of neutrophils, and fibroblasts in the treatment group compared to the control group on day 7. Conclusion: A combination of DPMSCS and RGCBE 50% accelerates traumatic ulcer wound healing by lowering ulcer diameter, decreasing neutrophil counts, and increasing fibroblast proliferation in vivo.

Nigella sativa toothpaste promotes anti-inflammatory and anti-destructive effects in a rat model of periodontitis.

OBJECTIVE: Periodontitis is an infectious disease that results in gingiva tissue damage. This study aimed to evaluate the effects of Nigella sativa (N. sativa) toothpaste in a periodontitis tissue repair based on inflammation and periodontal extracellular matrix in vivo. DESIGN: The periodontitis disease model was developed using Wistar rats infected with Porphyromonas gingivalis (P. gingivalis). The rats were divided into three main groups as follows: those that did not receive any toothpaste treatment; those that were treated with N. sativa toothpaste twice a day (simultaneously with P. gingivalis induction); and normal healthy rats. The rats were sacrificed after 1 and 7 days of animal modeling. The number of inflammatory cells, matrix metalloproteinase (MMP)1 + and MMP8 + cells, levels of cytokines (interleukin-1ß (IL-1ß) and prostaglandin E2 (PGE2)) and density of collagen type 1 were determined in the gingival tissues of the rats. RESULTS: The rats treated with N. sativa toothpaste had significantly lower numbers of neutrophils, macrophages and lymphocytes than the non-treated rats after 1 and 7 days of treatment; likewise, the levels of IL-1ß and PGE2 were lower in the treated experimental rats. In addition, the group treated with N. sativa toothpaste had fewer numbers of MMP1 + and MMP8 + cells and higher collagen density after 1 and 7 days of administration. CONCLUSIONS: N. sativa toothpaste exhibited anti-inflammatory effects by reducing both inflammatory cell count and activity. Additionally, N. sativa toothpaste demonstrated anti-destructive effects on the periodontal extracellular matrix. Thus, N. sativa toothpaste might be potentially used for the management of periodontitis.

Osteogenic Differentiation and Biocompatibility of Bovine Teeth Scaffold with Rat Adipose-derived Mesenchymal Stem Cells.

OBJECTIVE: Adipose-derived mesenchymal stem cells (ADMSCs) have great potential for regenerative medicine. These have been combined with biomaterials such as Bovine teeth that are preferred as a periodontal regeneration material. The main purpose of this study is to evaluate and analyze a biocompatibility test and osteogenic differentiation of bovine teeth scaffold seeded with ADMSCs in vitro. MATERIALS AND METHODS: A true experimental study with post-test only group design was conducted. Random sampling and Lameshow's formula were used to determine the sample. The scaffold, obtained from bovine teeth as the bone graft material, was analyzed using 3- (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and its attachment was evaluated by scanning electron microcopy (SEM) and micro-computed tomography with ADMSCs. ADMDSCs attachment present in the bovine teeth scaffold was assessed using SEM at 1-hour, 12-hour, and 24-hour intervals. STATISTICAL ANALYSIS: Analysis of variance was used to analyze the MTT assay results (p < 0.05) based on normality and homogeneity test (p > 0.05). RESULTS: The highest viability of cells (97.08%) was found at a concentration of 10% by means of an MTT test (p < 0.05). The results of three-dimensional bovine teeth scaffold showed the average particle size to be 500 µm. ADMSCs cell attachment to the scaffold bovine teeth showed a significant increase in the number of cells attached after 24 hours compared with those at 1 and 12 hours. Alizarin red staining showed an increase in ADMSC osteogenic differentiation after it was combined with bovine teeth scaffold. CONCLUSION: The scaffold from bovine teeth is biocompatible and accelerates osteogenic differentiation of ADMSC.
