Abstract
Background Periodontitis is a long-term, multifactorial inflammatory condition that is triggered by bacterial germs and interacts with the host's immune system. The unique attachment of fibrous tissue between the cementum and bone presents a challenge for periodontal regeneration. Aim To achieve the lowest optimum dose of BMP-7 that helps in periodontal regeneration, involving newly formed cementum, PDL and bone. Materials and methods Five healthy mongrel dogs were used for the study. A critical class III furcation defect was created using rotating burs. The bone defects (ten defects for each group) were allocated to one of the subsequent groups: (Group 1) control with the surgical defect only. (Group 2) Surgical defect implanted with hydrogel only (CS/β-GP). (Group 3) Surgical defect implanted with CS/BMP-7 (50 ng/ml). (Group 4) Surgical defect implanted with CS/BMP-7 (100 ng/ml). Results Histomorphometric and H&E analysis revealed a statistically significant difference in bone, PDL, and cementum regeneration defects filled with CS/BMP-7 (100 ng/ml) compared with other groups. Conclusion The standard effective dose for BMP-7 use in periodontal regeneration is 100 ng/ml.

Abstract
Recent investigations into the regulation of the inflammation in the periodontitis have revealed that chronic inflammatory diseases such as periodontitis are characterized by an imbalance in the proinflammatory and proresolution mediators and can be characterized by a failure of the resolution pathways in the late stages of the acute inflammatory response. The proresolution mediators, termed as specialized proresolving mediators (SPMs), comprise the lipoxins, resolvins, protectins, and maresins that are derived from the arachidonic acid or omega-3 polyunsaturated fatty acids. In the animal studies, treatment of the periodontitis with the topical SPMs return the inflammatory lesion to the homeostasis with the regeneration of all the components of the periodontal organ lost to the disease. In this article, the study investigates the immunomodulatory role of SPMs in the periodontal ligament stem cells (PDLSCs). Primary porcine PDLSCs (pPDLSCs) were stimulated with interleukin-1β (IL-1β) and interleukin-17 (IL-17) in vitro to simulate the periodontal inflammation in the presence or absence of SPMs. This study found that IL-1β and IL-17 synergistically activated the proinflammatory genes of pPDLSCs and altered the immune phenotype of pPDLSCs including the key signaling pathways. Addition of SPMs rescued the pPDLSCs phenotype and induced further production of the additional SPMs, which was reflected by upregulation of the requisite enzymes 12- and 15-lipoxygenase by pPDLSCs. This study interrogated the immunomodulatory actions of pPDLSCs on the monocytes/macrophages, focusing on the porcine CD14/CD16/CD163 markers by using flow cytometry. This study utilized the CD14+CD16+/CD14+CD16− ratio and CD163 on the monocytes/macrophages to differentiate between a proinflammation phenotype (lower ratio) and a resolution of the inflammation phenotype (higher ratio). This study also found that the conditioned medium from pPDLSCs treated with the cytokines and Maresin1 increased the CD14+CD16+/CD14+CD16− ratio and had the highest CD163 expression. This study concludes that in an inflammatory environment, pPDLSCs become proinflammatory and exert immunomodulatory functions. Maresin 1 resolves the inflammation by acting on pPDLSCs directly and by shifting the monocytes/macrophages phenotype to the proresolution dominance.

Abstract
Chronic periodontal is a very common infection that instigates the destruction of oral tissue, and for its treatment, it is necessary to minimize the infection and the defects regeneration. Periodontium consists of four types of tissues: (a) cementum, (b) periodontal ligament, (c) gingiva, and 4) alveolar bone. In separated cavities, regenerative process also allows various cell proliferations. Guided tissue regeneration (GTR) is a potential procedure that favors periodontal regrowth; however, some limitations (such as ineffective hemostatic property, poor mechanical property, and improper biodegradation) are also associated with it. This review mainly emphasizes on the following areas: (a) a summarized overview of the periodontium and its immunological situations, (b) recently utilized treatments for regeneration of distinctive periodontal tissues; (c) an overview of GTR membranes available commercially, and the latest developments on the characterization and processing of GTR membrane material; and 4) the function of the different non-polymeric/polymeric materials, which are acting as drug carriers, antibacterial agents, nanoparticles, and periodontal barrier membranes to prevent periodontal inflammation and to improve the strength of the GTR membrane.

Abstract
Periodontitis is a prevalent disease characterized by the loss of periodontal supporting tissues, bone, periodontal ligament, and cementum. The application of a bone tissue engineering strategy with Decellularized Human Amniotic Membrane (DAM) with adipose-derived stromal cells (ASCs) has shown to be convenient and valuable. This study aims to investigate the treatments of a rat periodontal furcation defect model with DAM, ASCs, and a mineralized extracellular matrix (ECM). Rat ASCs were expanded, cultivated on DAM, and with a bone differentiation medium for four weeks, deposited ECM on DAM. Periodontal healing for four weeks was evaluated by micro-computed tomography and histological analysis after treatments with DAM, ASCs, and ECM and compared to untreated defects on five consecutive horizontal levels, from gingival to apical. The results demonstrate that DAM preserves its structure during cultivation and healing periods, supporting cell attachment, permeation, bone deposition on DAM, and periodontal regeneration. DAM and DAM+ASCs enhance bone healing compared to the control on the gingival level. In conclusion, DAM with ASC or without cells and the ECM ensures bone tissue healing. The membrane supported neovascularization and promoted osteoconduction.

Abstract
AIM To evaluate whether treatment with resiniferatoxin (RTX) is capable of lowering the plasma levels of PGE2 and TNF-α, as well as histopathological parameters in inflammation of pulp tissue in a mouse experimental model. METHODOLOGY Ten groups of six BALB/c mice were formed as follows: healthy group (HC ), healthy group treated with RTX (HRTX ), two groups with pulp inflammation at 14 and 18 hours (PI14 /PI18 ), six groups with pulpal inflammation plus treatment with Ibuprofen (IBU14 /IBU18 ), dexamethasone (DEX14 /DEX18 ) and resiniferatoxin (RTX14 /RTX18 ) at 14 and 18 hours, respectively. Pulpal inflammation was induced through occlusal exposure of the pulp of the maxillary first molar. The plasma levels of PGE2 and TNF-α and the histological parameters of the pulp tissue of the HC and HRTX groups were evaluated at the time of acquiring the animals. In the other groups, the plasma levels of PGE2 and TNF-α and the histopathological parameters were evaluated at 14 and 18 hours after pulp damage. Plasma levels of PGE2 and TNF-α were quantified by ELISA, and the histopathological parameters were evaluated by H/E staining. Statistical significance was determined by one-way analysis of variance (ANOVA) to test for overall differences between group means. RESULTS A significant increase (*p < .05) in plasma levels of PGE2 and TNF-α occurred 14 and 18 hours after pulp damage. In addition, treatment with RTX significantly decreased (*p < .05) the plasma levels of PGE2 and TNF-α at 14 and 18 hours after pulp damage, as well as the infiltrate of inflammatory cells at 18 hours after pulp damage, similarly to treatment with ibuprofen and dexamethasone. CONCLUSION It was possible to detect systemic levels of PGE2 and TNF-α at 14 and 18 hours after pulp damage. Likewise, treatment with RTX was associated with an anti-inflammatory effect similar to treatment with ibuprofen and dexamethasone. These findings place resiniferatoxin as a therapeutic alternative in the treatment of inflammatory diseases in Dentistry.

Abstract
Periodontitis is an inflammatory disease that affects tooth-supporting tissues. Chronic inflammation can progress to periodontitis, which results in loss of alveolar bone. Asarylaldehyde is a potential substance for bone metabolism present in natural compounds. Here, we propose the application of asarylaldehyde in the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) to prevent bone loss. We investigated the effect of asarylaldehyde on hPDLSCs together with bone differentiation media in vitro. The osteogenic differentiation effect was observed after treatment of hPDLSCs with several concentrations of asarylaldehyde. After 21 days, osteogenic cells were identified by mineralization. We also observed that asarylaldehyde increased the mRNA expression of osteoblast-specific markers in hPDLSCs. Interestingly, asarylaldehyde regulated the levels of alkaline phosphatase (ALP) transcriptional activity through the p38/extracellular-signal-regulated kinase (ERK) signaling pathway. Notably, asarylaldehyde induced hPDLSCs to promote osteogenic differentiation. These results suggest that asarylaldehyde plays a key role in the osteogenic differentiation of hPDLSCs. Asarylaldehyde may be a good candidate for the application of natural compounds in future in periodontal regeneration.

Abstract
Periodontal disease (PD) is one of the most common inflammatory oral diseases, affecting approximately 47% of adults aged 30 years or older in the United States. If not treated properly, PD leads to degradation of periodontal tissues, causing tooth movement, and eventually tooth loss. Conventional clinical therapy for PD aims at eliminating infectious sources, and reducing inflammation to arrest disease progression, which cannot achieve the regeneration of lost periodontal tissues. Over the past two decades, various regenerative periodontal therapies, such as guided tissue regeneration (GTR), enamel matrix derivative, bone grafts, growth factor delivery, and the combination of cells and growth factors with matrix-based scaffolds have been developed to target the restoration of lost tooth-supporting tissues, including periodontal ligament, alveolar bone, and cementum. This review discusses recent progresses of periodontal regeneration using tissue-engineering and regenerative medicine approaches. Specifically, we focus on the advances of biomaterials and controlled drug delivery for periodontal regeneration in recent years. Special attention is given to the development of advanced bio-inspired scaffolding biomaterials and temporospatial control of multi-drug delivery for the regeneration of cementum-periodontal ligament-alveolar bone complex. Challenges and future perspectives are presented to provide inspiration for the design and development of innovative biomaterials and delivery system for new regenerative periodontal therapy.

Abstract
The manifestation of periodontitis-related inflammatory reaction is inevitably bound to the production of prostaglandins E2 and D2 which have been suggested to mediate osteoclastic and osteogenic effects within the affected tissue. We demonstrated the presence of PGE2 and PGD2 receptors on hMSCs on RNA level and with immunofluorescence. For each Prostaglandin, three concentrations were studied: 0.1; 0.5 or 1.0 µg/ml. A lower expression of EP1 and EP4 (PGE2 receptors 1 and 4) after stimulation with PGE2 was shown, thus a tendency to compromise osteogenic differentiation and metabolism. PGE2 induced a higher growth-rate during the first week, while a continuous inflammatory challenge determined a decrease of the proliferation of hMSCs. PGD2 inhibited cell growth irrespective of the duration of the stimulation. PGE2 and PGD2 have also negative effects on calcium deposition osteogenic, thus on differentiation of hMSCs. PGE2 and PGD2 seem to induce bone resorption also having indirectly a negative impact on the osteogenic differentiation of hMSCs. Thus, inhibitors of PGE2 and PGD2 can be used as adjunct to mechanical periodontal treatment.

Abstract
Abstract Prostaglandin E2 (PGE2) is a lipid mediator usually released during inflammation. This study aimed to investigate the potential of soluble or microsphere-loaded PGE2 on inducing differentiation of dental pulp stem cells. PGE2-loaded microspheres (MS) were prepared using an oil-in-water emulsion solvent extraction-evaporation process and were characterized. Mouse dental pulp stem cells (OD-21) were stimulated with soluble or PGE2-loaded MS (0.01 and 0.1 µM). Cell viability was determined by MTT colorimetric assay. Ibsp, Bmp2 and Runx2 expression was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) after 3, 6, and 24 h. The results showed that the soluble PGE2 reduced dental pulp stem cells viability after 24 h of stimulation whereas PGE2-loaded MS did not. Soluble PGE2 up-regulated Ibsp and Bmp2 at 3 h, differently from PGE2-loaded MS. On the other hand, PGE2-MS induced Bmp2 and Runx2 at 6 h and Ibsp at 24 h. In conclusion, our in vitro results show that PGE2, soluble or loaded in MS are not cytotoxic and modulateIbsp,Bmp2, andRunx2gene expression in cultured OD-21 cells.

Abstract
PGE2 is found to attenuate the bactericidal effects of kanamycin or ampicillin in Staphylococcus aureus, as well as the methicillin-resistant S. aureus (MRSA). Co-treatment with cyclooxygenase (COX) inhibitors (celecoxib, aspirin or naproxen) synergistically enhances kanamycin or ampicillin-induced cell death of S. aureus and MRSA. COX inhibitors repressed bacterial multidrug resistance through down-regulating efflux pump activity in antibiotics-treated S. aureus and MRSA. However, this synergistic bactericidal effects are reduced by the treatment with PGE2. PGE2 restores the efflux pump activity as well as increases biofilm formation in S. aureus and MRSA. Collectively, the enhancement of efflux pump activity and biofilm formation with PGE2 might partially explain the resistance to synergistic bactericidal effects between COX inhibitors and antibiotics in PGE2-treated S. aureus.
