Influence of freeze-dried bone allograft on free gingival graft survival and alveolar ridge maintenance in socket seal procedures: a randomized controlled clinical trial. Oral Maxillofac Surg 2024; 28:1327-1338. [PMID: 38789863 DOI: 10.1007/s10006-024-01262-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 05/19/2024] [Indexed: 05/26/2024]
Abstract
PURPOSE This study aimed to investigate the viability of free gingival grafts (FGG) and assess clinical and radiographic changes in the alveolar ridge following socket seal surgery with or without freeze-dried bone allograft (FDBA). MATERIALS AND METHODS Twenty-eight anterior and premolar tooth extractions were randomly allocated to 2 groups: socket graft of FDBA sealed with FGG (n = 15) and control with empty sockets sealed solely with FGG (n = 13). Photographs taken at 3, 7, 14, and 30 days post-surgery assessed FGG viability. Alveolar ridge volume was clinically evaluated via intraoral scanners before surgery and at 1 and 3 months post-surgery. CBCT scans taken immediately post-surgery and 3 months later assessed alveolar ridge dimensions. RESULTS FGG viability in both groups increased from day 3 and reached the maximum score on day 14. Alveolar ridge volume reduction at 3 months in the FDBA group was comparable to the control group. Buccal alveolar bone height reduction was significantly higher in the FDBA group than the control group, while palatal alveolar bone height was comparable. Alveolar bone width reduction was evident but not statistically significant between the groups. The FDBA group exhibited a significant alteration in bone volume compared to the control group. CONCLUSION Viability of FGG was not affected by graft filling materials. Sealing the socket with FGG effectively preserved socket integrity and ridge volume in minor socket defects using either graft filling material or not. This study was registered on 4 January 2021 on Thai Clinical Trials Registry (TCTR20210104001).

Dipotassium glycyrrhizate prevents oral dysbiosis caused by Porphyromonas gingivalis in an in vitro saliva-derived polymicrobial biofilm model. J Oral Biosci 2024; 66:575-581. [PMID: 38972505 DOI: 10.1016/j.job.2024.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 07/03/2024] [Accepted: 07/04/2024] [Indexed: 07/09/2024]
Abstract
OBJECTIVES Oral microbiome dysbiosis prevention is important to avoid the onset and progression of periodontal disease. Dipotassium glycyrrhizate (GK2) is a licorice root extract with anti-inflammatory effects, and its associated mechanisms have been well-reported. However, their effects on the oral microbiome have not been investigated. This study aimed to elucidate the effects of GK2 on the oral microbiome using an in vitro polymicrobial biofilm model. METHODS An in vitro saliva-derived polymicrobial biofilm model was used to evaluate the effects of GK2 on the oral microbiome. One-week anaerobic culture was performed, in which GK2 was added to the medium. Subsequently, microbiome analysis was performed based on the V1-V2 region of the 16 S rRNA gene, and pathogenicity indices were assessed. We investigated the effects of GK2 on various bacterial monocultures by evaluating its inhibitory effects on cell growth, based on culture turbidity. RESULTS GK2 treatment altered the microbiome structure and decreased the relative abundance of periodontal pathogenic bacteria, including Porphyromonas. Moreover, GK2 treatment reduced the DPP4 activity -a pathogenicity index of periodontal disease. Specifically, GK2 exhibited selective antibacterial activity against periodontal pathogenic bacteria. CONCLUSIONS These findings suggest that GK2 has a selective antibacterial effect against periodontal pathogenic bacteria; thus, preventing oral microbiome dysbiosis. Therefore, GK2 is expected to contribute to periodontal disease prevention by modulating the oral microbiome toward a state with low inflammatory potential, thereby utilizing its anti-inflammatory properties on the host.

Abstract
PURPOSE To evaluate the survival rates of dental implants with a hybrid macrostructure and the surface biomimetically coated with nanohydroxyapatite, placed in horizontally atrophic maxillae previously submitted to the guided bone regeneration (GBR) procedure, associated with the use of a deproteinized bovine bone graft (DBB). METHODS Twenty-five patients who received 196 implants were involved in this study. First, these patients were submitted to GBR procedures and maxillary sinus lift, where DBB was used as the grafting material. The dental implants were placed after a minimum period of 6 months of the grafting procedures. The patients were followed up every six months and clinical/radiographic examinations were performed to assess the implants, using the following indicators as a reference: (1) Absence of mobility; (2) Absence of pain. Data about the age, surgery time, smoking status, implant size, and time between the grafting procedure and implant placement were correlated with implant failures. RESULTS Twelve implants failed, generating a survival rate of 94.23%. None of the variables analysed correlated with the implant failures. CONCLUSION Implants with a hybrid macrostructure and surface biomimetically coated with nanohydroxyapatite present good survival rates in horizontally atrophic maxillae grafted with DBB.

Abstract
BACKGROUND AND OBJECTIVE There is a relative lack of evidence from observational studies of older populations investigating the association between chronic periodontitis and cerebro-cardiovascular diseases. Accordingly, we investigated the risk of cerebro-cardiovascular diseases according to the severity of chronic periodontitis among older adults. METHODS Data on older adults with chronic periodontitis were extracted from the Korea National Health Insurance Service-Senior Cohort Database using diagnosis codes and dental procedures. Participants were divided into two exposure groups. Among 46 737 participants eligible for inclusion, 21 905 (46.9%) had newly diagnosed mild chronic periodontitis, and 24 832 (53.1%) had newly diagnosed severe chronic periodontitis. To determine the risk of cerebro-cardiovascular diseases, including ischemic stroke, haemorrhagic stroke, and myocardial infarction, multivariable-adjusted Cox proportional hazards modelling was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) in this retrospective follow-up study. RESULTS A total of 3453 (7.4%) outcomes were identified during a mean follow-up of 6.1 years. Kaplan-Meier analysis revealed that disease-free probability was lower in the severe group than in the mild group (log-rank P < .001). In the multivariable-adjusted model, the HR for cerebro-cardiovascular diseases in the severe group (relative to the mild group) was 1.16 (95% CI: 1.09-1.25). In individual outcome analysis, ischemic stroke and myocardial infarction were associated with chronic periodontitis severity, but haemorrhagic stroke was not. CONCLUSION The severity of chronic periodontitis could be associated with the risk of cerebro-cardiovascular diseases in older adults.

Abstract
Bone and tooth defects can considerably affect the quality of life and health of patients, and orthopedic implants remain the primary method of addressing such defects. However, implant materials cannot coordinate with the immune microenvironment because of their biological inertness, which may lead to implant loosening or failure. Motivated by the microstructure of nacre, we engineered a biomimetic micro/nanoscale topography on a tantalum surface using a straightforward method. This comprised an organized array of tantalum nanotubes arranged in a brick wall structure, with epigallocatechin gallate acting as "mortar." The coating improved the corrosion resistance, biocompatibility, and antioxidant properties. In vitro and in vivo evaluations further confirmed that coatings can create a favorable bone immune microenvironment through the synergistic effects of mechanochemistry and enhance bone integration. This research offers a new viewpoint on the creation of sophisticated functional implants, possessing vast potential for use in the regeneration and repair of bone tissue.

Abstract
The dental implant market has experienced explosive growth, owing to the widespread acceptance of implants as the core of oral rehabilitation. Clinically, achieving simultaneous anti-infective effects and rapid osseointegration is a crucial but challenging task for implants. The demand for implants with long-term broad-spectrum antibacterial and immune-osteogenic properties is growing. Existing methods are limited by a lack of safety, efficiency, short-lasting anti-infective ability, and inadequate consideration of the immunomodulatory effects on osteogenesis. Herein, a ZnO/black TiO2-x heterojunction surface structure was designed as a near-infrared (NIR) light-responsive nanofilm immobilized on a titanium (Ti) implant surface. This nanofilm introduces abundant oxygen vacancies and heterojunctions, which enhance the photothermal and photoelectric abilities of Ti implants under NIR illumination by narrowing the band gap and improving interfacial charge transfer. The "photo-thermo-electric" implant exhibits excellent broad-spectrum antibacterial efficacy against three dental pathogenic bacteria (Porphyromonas gingivalis, Fusobacterium nucleatum, and Staphylococcus aureus, >99.4%) by destroying the bacterial membrane and increasing the production of intracellular reactive oxygen species. Additionally, the implant can effectively eliminate mature multispecies biofilms and kill bacteria inside the biofilms under NIR irradiation. Meanwhile, this implant can also induce the pro-regenerative transformation of macrophages and promote osteoblast proliferation and differentiation. Moreover, in vivo results confirmed the superior antibacterial and osteoimmunomodulatory properties of this dental implant. RNA sequencing revealed that the underlying osteogenic mechanisms involve activation of the Wnt/β-catenin signaling pathway and bone development. Overall, this versatile "photo-thermo-electric" platform endows implants with anti-infection and bone integration performance simultaneously, which holds great potential for dental implants.

Soft-Tissue Phenotype as a Risk Indicator of Peri-Implantitis and Peri-Implant Soft-Tissue Dehiscence-A Cross-Sectional Study. J Clin Periodontol 2024. [PMID: 39189550 DOI: 10.1111/jcpe.14059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 07/23/2024] [Accepted: 08/06/2024] [Indexed: 08/28/2024]
Abstract
AIM To investigate the association, as well as to characterize the associated panel of pro- and anti-inflammatory markers, between the different components of the peri-implant phenotype and the presence of peri-implantitis/peri-implant soft-tissue dehiscence (PISTD). MATERIALS AND METHODS A total of 324 implants in 112 patients were included. The following components of the peri-implant phenotype were clinically measured through the use of a manual periodontal probe or a digital calliper: keratinized mucosa width (PIKM-W), mucosal thickness (MT), attached mucosa (AM) and vestibulum depth (VD). The presence of peri-implantitis and PISTD was assessed through clinical and radiographic examination. Mixed-models logistic regression analyses were performed to analyse the association between peri-implant phenotype and the presence of peri-implantitis or PISTD, adjusting for relevant confounders. Multiplex immunoassays were employed to evaluate the peri-implant crevicular fluid levels of a panel of pro- and anti-inflammatory markers. RESULTS Peri-implant health, peri-implant mucositis and peri-implantitis were diagnosed in 36.6%, 21.4% and 42% of the patients (classified according to their worst implant) and 35.2%, 34.3%, and 30.5% of the implants, respectively. In the multi-level multiple regression model, the absence of PIKM-W (odds ratio [OR] = 9.24; 95% CI: 2.73-31.28), the absence of attached mucosa (OR = 19.58; 95% CI: 6.12-62.56) and a reduced (<4 mm) vestibulum depth (OR = 2.61; 95% CI: 1.05-6.48) were associated with peri-implantitis. Similarly, the absence of PIKM-W (OR = 6.32; 95% CI: 1.67-23.83), a thin (<2 mm) mucosa (OR = 157.75; 95% CI: 14.06-1769.9) and a reduced vestibulum depth (OR = 3.32; 95% CI: 1.02-10.84) were associated with the presence of PISTD. Implants with PIKM-W = 0 mm showed statistically significantly higher levels of interferon-γ in both regular (≥2 maintenance/year) and irregular (<2 maintenance/year) compliers (p = 0.046 and p = 0.012). In irregular compliers, the absence of PIKM-W was also associated with statistically significantly higher levels of interleukin (IL)-1β and IL-21 (p = 0.016, p = 0.046). These associations were independent of the effect of relevant confounders (e.g., plaque, compliance with maintenance, etc.). CONCLUSIONS Within their limits, the present findings indicate that (a) peri-implant soft-tissue phenotype appears to be associated with the presence of peri-implantitis and PISTD, and (b) in the absence of PIKM-W, the inflammatory response seems to be dysregulated and the soft-tissue remodelling up-regulated.

Abstract
PURPOSE The purpose of this study is to describe the oral health status of inmates. The secondary aims were to compare recidivists with first-time offenders and also study the impact of psychoactive drugs on the oral health status. DESIGN/METHODOLOGY/APPROACH This retrospective study included 120 male inmates from a French prison. Data from the medical and the dental questionnaires and examinations were collected and analyzed. FINDINGS The results showed that overall, the inmates had a poor oral health despite their young age. This population was at high risk regarding caries and periodontal diseases due to sedentary behaviors, improper diet, drug, alcohol and tobacco consumption. In total, 93% of inmates had at least one decayed untreated tooth and 95% had periodontal disease. The use of psychoactive drugs seemed strongly related to oral health status degradation. However, the comparison between recidivists and first-time offenders showed few differences. PRACTICAL IMPLICATIONS The need for periodontal and dental care is considerable in this population and increased in this environment where risk factors such as addictive behaviors and poor eating habits are common. The impact of psychoactive drugs on oral health should also be taken into consideration. SOCIAL IMPLICATIONS Unfortunately, even though strategies for the prevention and management of oral health in prisons have been put in place for some years, the results still seem insufficient. ORIGINALITY/VALUE There are still few studies that analyze the impact of this medication on oral health in prisons.

Abstract
The association between periodontal diseases and the risk of gastrointestinal cancers, especially site-specific gastrointestinal cancers, remains unclear. Here, we comprehensively searched PubMed, EMBASE, Web of Science, and Google Scholar from inception to April 2024 to identify relevant studies. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated with a random-effects model. Subgroup analyses and sensitivity analyses were conducted to confirm the robustness of the main findings in different populations. This study was reported according to PRISMA 2020 guidelines. In total, we identified 19 studies, including 16.6 million participants. Individuals with periodontal diseases had an increased risk of overall gastrointestinal cancers compared with those without periodontal diseases (HR 1.31, 95% CI 1.16-1.49). Periodontal diseases significantly increased the risk of esophageal cancer by 39% (HR 1.39, 95% CI 1.15-1.68), gastric cancer by 13% (HR 1.13, 95% CI 1.01-1.26), colorectal cancer by 21% (HR 1.21, 95% CI 1.05-1.39), pancreatic cancer by 35% (HR 1.35, 95% CI 1.00-1.82), and liver cancer by 9% (HR 1.09, 95% CI 1.04-1.13). The risk of gastrointestinal cancers was significantly increased by periodontitis (HR 1.45, 95% CI 1.14-1.85), gingivitis (HR 1.03, 95% CI 1.01-1.04), and periodontitis/gingivitis (HR 1.27, 95% CI 1.07-1.51). Furthermore, severe periodontal diseases showed a significantly increased risk of gastrointestinal cancer (HR 1.79, 95% CI 1.07-2.99). Results of sensitivity analyses for site-specific gastrointestinal cancers were robust with the main findings. In summary, periodontal diseases, especially severe periodontitis, increase the risk of overall and site-specific gastrointestinal cancers. Interventions to prevent and manage periodontal diseases may reduce the risk of developing gastrointestinal cancers.

[PMID: 39187444 DOI: 10.1111/cid.13368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 06/26/2024] [Accepted: 07/17/2024] [Indexed: 08/28/2024]
Abstract
PURPOSE This multicenter cross-sectional clinical study aimed to evaluate the membrane perforation rate during transcrestal sinus floor elevation (TSFE) using osseodensification (OD) burs and assess risk factors associated with the procedure. MATERIALS AND METHODS This study was conducted in six centers, following ethical standards and approved by local committees. It included patients over 18 years old missing maxillary posterior teeth with crestal residual bone height (RBH) ≥2 and ≤6 mm. Preoperative evaluations were done, including CBCT scans, to assess bone dimensions and sinus health. All centers and surgeons followed a standardized surgical protocol for TSFE using OD burs. Surgical complications, particularly sinus membrane perforations, were recorded and analyzed. Factors such as implant site, premolars or molars, as well as, healed or fresh socket, along with initial RBH were evaluated for their impact on membrane perforation rate. Descriptive statistics, χ2, and logistic regression analysis were used to analyze the data. RESULTS A total of 621 subjects with an average age of 57.9 years were included. Sinus lifting was performed at 670 sites, with 621 implants placed in the maxilla. The majority of sinus lifts were done in the molar region (76.87%) and in healed bone sites (74.33%). The average RBH was 5.1 mm (ranging from 2 to 7 mm). Sinus membrane perforation occurred in 49 cases (7.31%). RBH ≤3 mm posed a risk factor for sinus membrane perforations followed by RBH >3 and ≤5 mm. Tooth region and implant site were not associated as risk factors for sinus membrane perforation. CONCLUSION OD drilling used for TSFE resulted in low membrane perforation rate. Challenging scenarios of severe posterior maxillary atrophy presented as risk factors for increased perforation rate.

Abstract
OBJECTIVE To analyze, through a systematic review, the effectiveness of educational tools (ETs) in Oral Health Programs (OHPs) for pregnant women in improving their oral status and that of their babies. METHOD Searches were carried out in 5 electronic databases. Randomized (RCTs) and non-randomized clinical trials (CTs) were selected that included pregnant women exposed or not to ETs in OHPs, whose oral health status, in the pre- or postnatal period, or of their babies were verified. The types of ETs, outcomes, and results were extracted. Bias risk was assessed by ROBINS-I and RoB 2.0; and the certainty of the evidence (CE) by GRADE. RESULTS A total of nine studies were included. Most used more than one ET (n = 8), with verbal guidance used in all (n = 9). Mothers showed a reduction in biofilm (n = 3), caries (n = 4) and periodontitis (n = 4). All studies with babies (n = 3) were successful in preventing caries. RCTs (n = 3) were classified as low risk of bias (n = 1), with concerns (n = 1) and high risk of bias (n = 1). CTs (n = 6) presented risk of bias as low (n = 2), serious (n = 1) and critical (n = 3). Studies about caries in babies showed high CE, and those who evaluated caries and periodontal parameters/biofilm in the mother had moderate and low CE, respectively. CONCLUSION ETs as a strategy of OHPs for pregnant women can be effective in preventing caries in themselves and in their babies. However, despite the improvement of the mothers' oral hygiene and gingival condition, the CE was low considering this parameter.

Abstract
Bone aging and decreased autophagic activity are related but poorly explored in the jawbone. This study aimed to characterize the aging jawbones and jawbone-derived stromal cells (JBSCs) and determine the role of autophagy in jawbone mass decline. We observed that the jawbones of older individuals and mice exhibited similar age-related bone loss. Furthermore, leptin receptor (LepR)-lineage cells served as the primary source for in vitro cultured and expanded JBSCs, referred to as LepR-Cre+/JBSCs. RNA-sequencing data from the jawbones and LepR-Cre+/JBSCs showed the upregulated expression of the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway during aging. Through single-cell transcriptomics, we identified a decrease in the proportion of osteogenic lineage cells and the activation of the PI3K/AKT pathway in LepR-lineage cells in aging bone tissues. Reduced basal autophagic activity, diminished autophagic flux, and decreased osteogenesis occurred in the jawbones and LepR-Cre+/JBSCs from older mice (O-mice; O-JBSCs). Pharmacologic and constitutive autophagy activation alleviated the impaired osteogenesis in O-JBSCs. In addition, the suppression of mTOR-induced autophagy improved the aging phenotype of O-JBSCs. The activation of autophagy in LepR-Cre+/JBSCs using chemical autophagic activators reduced the alveolar bone resorption in O-mice. Therefore, our study demonstrated that ATG molecules and pathways are crucial in jawbone aging, providing novel approaches to understanding age-related jawbone loss.

Abstract
The average age and obesity prevalence are increasing globally. Both aging and metabolic disease burden increase the risk of oral squamous cell carcinoma (OSCC) through profound effects on the immunological and metabolic characteristics within the OSCC tumor microenvironment. While the mechanisms that link aging and obesity to OSCC remain unclear, there is evidence that the antitumor responses are diminished in both conditions. Remarkably, however, immune checkpoint blockade, a form of cancer immunotherapy, remains intact despite the enhanced immunosuppressive tumor microenvironment in the context of either aging or obesity. Herein, we review the current knowledge of how aging and systemic metabolic changes affect antitumor immunity with an emphasis on the role of tumor-associated macrophages that greatly contribute to tumor immunosuppression. Key aspects discussed include the mechanisms of angiogenesis, cytokine release, phagocytosis attenuation, and immune cell recruitment during obesity and aging that create an immune-suppressive tumor microenvironment by recruitment and repolarization of tumor-associated macrophages. Through a deeper appreciation of these mechanisms, the development of novel therapeutic approaches to control OSCC will provide more refined management of the tumor microenvironment in the context of aging and obesity.

Abstract
The global growth of the aging population has resulted in an increased prevalence of neurodegenerative diseases, characterized by the progressive loss of central nervous system (CNS) structure and function. Given the high incidence and debilitating nature of neurodegenerative diseases, there is an urgent need to identify potential biomarkers and novel therapeutic targets thereof. Apurinic/apyrimidinic endonuclease 1 (APE1), has been implicated in several neurodegenerative diseases, as having a significant role. Abnormal APE1 expression has been observed in conditions including Alzheimer's disease, stroke, amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, and epilepsy. However, whether this dysregulation is protective or harmful remains unclear. This review aims to comprehensively review the current understanding of the involvement of APE1 in neurodegenerative diseases.

Abstract
Several etiologies may contribute to the development of excessive gingival display (EGD). However, little, if any, consideration has been given to the potentially significant role of prominent buccal maxillary exostoses (BMEs) in EGD etiology. Therefore, the aim of this report was to highlight the contribution of BMEs to EGD. Two patients complaining of EGD were evaluated, and BMEs were found associated with a hypermobile upper lip, vertical maxillary excess, and altered passive eruption. Both patients received esthetic crown lengthening (ECL) as the first surgical intervention. The BMEs were removed by osteoplasty performed during ECL. The resulting smile and EGD changes were evaluated 3 to 6 months postoperatively. An extraordinary amount of gingival display reduction was found in both patients (8 mm and 6 mm), a highly atypical outcome for ECL alone. BME removal on its own represented 75% and 67% of the EGD decrease, respectively. The exostoses removal-associated EGD decreases corresponded to observed reductions in lip mobility during smile. Sizeable BMEs can contribute significantly to the etiology of EGD, in part through an effect on lip mobility during smile. Proper management of such BMEs through osteoplasty provides meaningful EGD reduction, resulting in improvements of smile esthetics and patient satisfaction.

Effects of a 4-week free-sugar avoidance during periodontal therapy: An explorative randomized controlled clinical trial. J Periodontol 2024.

Abstract
BACKGROUND This study investigated the effect of a 4-week free-sugar avoidance on periodontal parameters during periodontal therapy. METHODS Twenty-one patients with untreated periodontitis and daily free-sugar intake were allocated to a sugar avoidance group (SAG) and a control group (CG). The SAG received a 45-min dietary consultation and was instructed to avoid free sugars during the following 4 weeks after subgingival instrumentation, while the CG continued with their regular diet. Bleeding on probing (BOP), plaque control record, body weight (BW), visceral fat (FATv), and a food frequency questionnaire (FFQ) were collected at baseline (T1), 4 weeks (T2), and 8 weeks (T3) after subgingival instrumentation. RESULTS The main outcome parameter BOP was significantly reduced at T2 by 40.3% ± 15.54 in the SAG and 34% ± 12.47 in the CG (intra-p value both <0.001, inter-p value 0.361). A linear regression analysis of changes at patient level adjusted for age and FATv revealed a significant group difference for BOP (regression coefficient = -6.8; p = 0.019). Significant reductions were observed in BW, FATv and mean daily intake of free sugars (-14.4 g/day), and a significant increase of vitamin C derived from fruits (75.89 mg/day) at T2 in the SAG only. CONCLUSION This study may indicate additional beneficial effects of a sugar avoidance on periodontal and metabolic parameters, and nutritional intake during periodontal therapy. German Clinical Trials Register (DRKS00026699). PLAIN LANGUAGE SUMMARY The current widespread free-sugar consumption is linked to an increasing incidence of chronic non-communicable diseases. Data indicate a relationship between sugar intake and a higher prevalence of periodontitis and increased gingival inflammation. This study showed that free-sugar avoidance after periodontal therapy had additional beneficial effects on periodontal and metabolic parameters in 10 test and 11 control patients. After 4 weeks of avoiding free sugars like sweets, processed white flour, juice, and so forth, periodontal bleeding was significantly reduced in both groups (-40.3% test group, -34% control group). Further regression analysis revealed a significant difference between groups favoring the intervention. Additionally, body weight and visceral fat were significantly reduced in the intervention group, only. To avoid sugar, patients were allowed to replace it with whole fruit, which led to increased levels of micronutrients such as vitamin C. Therefore, free-sugar avoidance may be of therapeutic benefit in addition to periodontal therapy. Further research is needed to investigate this effect in larger cohorts.

Abstract
Our previous clinical observations showed that platelet rich fibrin (PRF) can be used to deliver antibiotics to attenuate postoperative complications after unilaterally impacted mandibular third molar surgery (IMTMS). In order to begin understanding the mechanism involved in the beneficial in vivo effects of PRF-mediated delivery of antibiotics, in vitro studies were performed, which showed that PRF preparations containing amoxicillin/clavulanic acid or clindamycin significantly inhibited the growth of S. aureus bacteria. In our previous study, comparisons were made between control and treated groups. However, since variations among individual patients could possibly affect the results, the current study included patients with bilaterally symmetric impacted mandibular third molars, allowing us to compare control and antibiotic treatment within each patient. The effects of PRF preparations containing amoxicillin/clavulanic acid or clindamycin on IMTMS was tested in 60 clinical cases. Antibiotic-injected PRF treatment after bilaterally IMTMS resulted in significantly reduced pain, less use of analgesics, and reduced swelling and trismus compared to the control group (PRF without antibiotics) confirming our previous results after unilaterally IMTMS. The in vitro results support the hypothesis that in vivo delivery of antibiotics using PRF produces therapeutic effects after IMTMS by attenuating bacterial infection and inflammation.

Abstract
In vitro models are invaluable tools for deconstructing the biological complexity of the periodontal ligament (PDL). Model systems that closely reproduce the 3-dimensional (3D) configuration of cell-cell and cell-matrix interactions in native tissue can deliver physiologically relevant insights. However, 3D models of the PDL that incorporate mechanical loading are currently lacking. Hence, we developed a model where periodontal tissue constructs (PTCs) are made by casting PDL cells in a collagen gel suspended between a pair of slender, silicone posts for magnetic tensile loading. Specifically, one of the posts was rigid and the other was flexible with a magnet embedded in its tip so that PTCs could be subjected to tensile loading with an external magnet. Additionally, the deflection of the flexible post could be used to measure the contractile force of PDL cells in the PTCs. Prior to tensile loading, second harmonics generation analysis of collagen fibers in PTCs revealed that incorporation of PDL cells resulted in collagen remodeling. Biomechanical testing of PTCs by tensile loading revealed an elastic response at 4 h, permanent deformation by 1 d, and creep elongation by 1 wk. Subsequently, contractile forces of PDL cells were substantially lower for PTCs under tensile loading. Immunofluorescence analysis revealed that tensile loading caused PDL cells to increase in number, express higher levels of F-actin and α-smooth muscle actin, and become aligned to the tensile axis. Second harmonics generation analysis indicated that collagen fibers in PTCs progressively remodeled over time with tensile loading. Gene expression analysis also confirmed tension-mediated upregulation of the F-actin/Rho pathway and osteogenic genes. Our model is novel in demonstrating the mechanobiological behavior that results in cell-mediated remodeling of the PDL tissue in a 3D context. Hence, it can be a valuable tool to develop therapeutics for periodontitis, periodontal regeneration, and orthodontics.

Abstract
BACKGROUND To compare the efficacy of combined treatment of Er:YAG laser (ERL) and low-level laser therapy (LLLT) with single laser applications, and scaling and root planing (SRP) for non-surgical periodontal treatment. METHODS In a randomized controlled trial, 25 non-smoking Stage II or Stage III periodontitis patients were recruited. The four intraoral quadrants were randomly assigned to four different treatments: (1) combined application with ERL plus SRP plus LLLT; (2) ERL plus SRP; (3) SRP plus LLLT; and (4) SRP. We assessed periodontal indexes, including probing depth (PD), clinical attachment level (CAL), bleeding index (BI), and plaque index (PLI), along with three cytokines (IL-1β, TNF-α, IL-10) from gingival crevicular fluid and red complex pathogens from subgingival dental plaque at baseline, 3 months, and 6 months. RESULTS For initial moderate pockets (4 mm ≤ PD ≤ 6 mm), quadrants treated with ERL+SRP+LLLT, ERL+SRP, and SRP+LLLT exhibited greater PD improvement compared to the control (SRP) quadrants at the 3-month follow-up (1.25 ± 1.06, 1.23 ± 1.12, 1.00 ± 1.21 vs. 0.98 ± 1.21 mm) and the 6-month follow-up (1.35 ± 1.06, 1.23 ± 1.17, 1.35 ± 0.98 vs. 0.98 ± 1.23 mm) (p = 0.002). Quadrants treated with ERL+SRP+LLLT and SRP+LLLT showed more CAL gain means than the control quadrants at the 3-month follow-up (0.96 ± 1.42, 0.61 ± 1.39 vs. 0.55 ± 1.57 mm) and the 6-month follow-up (0.84 ± 1.54, 0.89 ± 1.49 vs. 0.48 ± 1.68 mm) (p = 0.008). For initial deep pockets (PD ≥ 7 mm), the ERL+SRP+LLLT quadrants had more PD improvement and CAL gain compared to the control quadrants at follow-up. There were no significant differences in BI, PLI, inflammatory cytokines, and periodontal pathogens among the four groups. CONCLUSION The combined application of ERL and LLLT demonstrated potential efficacy in reducing PD, particularly for deep pockets. PLAIN LANGUAGE SUMMARY To compare the therapy effect of combined use of Er:YAG laser (ERL) and low level laser therapy (LLLT) with single laser applications, and traditional periodontal treatment (SRP). A total of 25 non smoking patients with periodontitis were involved, and their mouths were divided into four sections, each receiving a different treatment: ERL+SRP+LLLT, ERL+SRP, SRP+LLLT, and SRP. Clinical indexes and laboratory indicators were assessed at baseline, 3 months, and 6 months. After six months, for initial moderate pockets, combined laser group and single laser group showed better improvements than traditional group in reducing the depth of periodontal pockets and increasing attachment levels. But for initial deep pockets, only combined laser group showed better improvement than traditional group. There were no significant differences in bleeding, plaque, inflammation, or harmful bacterial levels among the groups. These findings suggest that the integration of Er:YAG laser and low level laser therapy into standard periodontal treatment may enhance the treatment's benefits in reducing pocket depth, especially for severe conditions.

Abstract
Microorganisms play an important role in the pathogenesis of inflammatory bowel disease (IBD). The oral cavity, the second-largest microbial niche, is connected to the gastro-intestinal tract. Ectopic gut colonization by oral microbes is a signature of IBD. Current studies suggest that patients with IBD often report more oral manifestations and these oral issues are closely linked with disease activity. Murine studies have indicated that several oral microbes exacerbate intestinal inflammation. Moreover, intestinal inflammation can promote oral microbial dysbiosis and the migration of oral microbes to the gastro-intestinal tract. The reciprocal consequences of oral microbial dysbiosis and IBD, specifically through metabolic alterations, have not yet been elucidated. In this review, we summarize the relationship between oral bacteria and IBD from multiple perspectives, including clinical manifestations, microbial dysbiosis, and metabolic alterations, and find that oral pathogens increase anti-inflammatory metabolites and decrease inflammation-related metabolites.

Stem Cell Res Ther 2024; 15:270. [PMID: 39183362 PMCID: PMC11346187 DOI: 10.1186/s13287-024-03882-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Accepted: 08/11/2024] [Indexed: 08/27/2024] Open
Abstract
BACKGROUND Periodontal tissue loss is the main reason for tooth mobility and loss caused by periodontal disease. Dental follicle stem cells (DFSCs) have significant therapeutic potential in periodontal regeneration, which maybe mainly depends on their potent immunomodulatory capacity. Consequently, this study aims to elucidate the impact of implanted xenogenous DFSCs on innate immune responses during early and late stages in the periodontal defect repair period. METHODS To trace and investigate the immunomodulation mechanisms of DFSCs in vivo, DFSCs were engineered (E-DFSCs) using lentiviral vectors expressing CD63-enhanced green fluorescent protein (CD63-EGFP) and β-Actin-mCherry protein (ACTB-mCherry) to exhibit green and red fluorescence. The biological characteristics and functions of E-DFSCs were verified by proliferation, differentiation, and co-culture experiments in vitro. In vivo, the periodontal regeneration capacity of E-DFSCs was detected by implantation of murine periodontal defect model, and the response of innate immune cells was detected at the 1st, 3rd, and 5th days (early stage) and 4th week (late stage) after implantation. RESULTS In vitro assessments showed that E-DFSCs retain similar properties to their non-engineered counterparts but exhibit enhanced macrophage immunomodulation capability. In mice models, four-week micro-CT and histological evaluations indicated that E-DFSCs have equivalent efficiency to DFSCs in periodontal defect regeneration. At the early stage of repair in mice periodontal defect, fluorescence tracking showed that implanted E-DFSCs might primarily activate endogenous cells through direct contact and indirect actions, and most of these cells are myeloperoxidase-positive neutrophils. Additionally, compared with the control group, the neutrophilic infiltration and conversion of N2-type were significantly increased in the E-DFSC group. At the late stage of defect regeneration, more M2-type macrophages, fewer TRAP + osteoclasts, and an upregulated OPG/RANKL ratio were detected in the E-DFSC group compared to the control group, which indicated that immune balance tilts towards healing and bone formation. CONCLUSION The xenogenous implanted DFSCs can induce the N2 phenotype of neutrophils in the early stage, which can activate the innate immune mechanism of the host to promote periodontal tissue regeneration.

Abstract
BACKGROUND The collaboration between otolaryngologists and dental providers is crucial for the planning and execution of maxillary sinus elevation (MSE) procedures, which are integral to successful dental implant placements. PURPOSE This article examines the essential role of otolaryngological assessments in identifying potential sinonasal risks that could impact the outcomes of MSE. MATERIALS AND METHODS A comprehensive narrative review of existing literature was conducted. DISCUSSION The review underscores the importance of thorough preoperative evaluations, including patient history, computed tomography (CT) or cone-beam CT (CBCT) scans, and nasal endoscopy, to mitigate sinonasal health risks. It details various clinical scenarios and patient assessments, emphasizing a systematic approach to diagnosing and managing sinonasal conditions proactively. The discussion reveals that while some sinus conditions may not significantly affect MSE success, conditions impacting mucociliary clearance and sinus drainage are critical risk factors requiring otolaryngological intervention. Additionally, the article introduces a grading system to assist clinicians in identifying patients who would benefit from otolaryngological evaluations prior to MSE. CONCLUSION This review highlights the value of interdisciplinary collaboration and standardized protocols in enhancing the predictability and safety of MSE procedures, ultimately improving patient outcomes.

Abstract
BACKGROUND Oral microbiota comprises polymicrobial communities shaped by mutualistic coevolution with the host, contributing to homeostasis and regulating immune function. Nevertheless, dysbiosis of oral bacterial communities is associated with a number of clinical symptoms that ranges from infections to oral cancer. Peri-implant diseases are biofilm-associated inflammatory conditions affecting the soft and hard tissues around dental implants. Characterization and identification of the biofilm community are essential for the understanding of the pathophysiology of such diseases. For that sampling methods should be representative of the biofilm communities Therefore, there is a need to know the effect of different sampling strategies on the biofilm characterization by next generation sequencing. METHODS With the aim of selecting an appropriate microbiome sampling procedure for periimplant biofilms, next generation sequencing was used for characterizing the bacterial communities obtained by three different sampling strategies two months after transepithelial abutment placement: adjacent periodontal crevicular fluid (ToCF), crevicular fluid from transepithelial abutment (TACF) and transepithelial abutment (TA). RESULTS Significant differences in multiple alpha diversity indices were detected at both the OTU and the genus level between different sampling procedures. Differentially abundant taxa were detected between sample collection strategies, including peri-implant health and disease related taxa. At the community level significant differences were also detected between TACF and TA and also between TA and ToCF. Moreover, differential network properties and association patterns were identified. CONCLUSIONS The selection of sample collection strategy can significantly affect the community composition and structure. TRIAL REGISTRATION This research is part of a randomized clinical trial that was designed to assess the effect of transepithelial abutment surface on the biofilm formation. The trial was registered at Trial Registration ClinicalTrials.gov under the number NCT03554876.

Abstract
Treatments to reduce periodontal inflammation and rescue periodontitis bone resorption have been of interest to researchers. Bone tissue engineering materials have been gradually used in the treatment of bone defects, but periodontal bone tissue regeneration still faces challenges. Considering the biocompatibility factor, constructing bionic scaffolds with natural extracellular matrix properties is an ideal therapeutic pathway. Based on the pathological mechanism of periodontitis, in this study, short peptide and nanometer inorganic particles were comingled to construct NapKFF-nano CaF2 supramolecular composite hydrogels with different ratios. Material characterization experiments confirmed that the composite hydrogel had suitable mechanical properties and a three-dimensional structure that can function in the resorption region of the alveolar bone and provide spaces for cell proliferation and adhesion. The release of low concentrations of fluoride and calcium ions has been shown to have positive biological effects in both in vivo and in vitro experiments. Vitro experiments confirmed that the composite hydrogel had good biocompatibility and promoted osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). Microbiological experiments confirmed that the composite hydrogel inhibited the activity of periodontal pathogenic bacteria. In animal studies, composite hydrogel applied to periodontitis rats in vivo can effectively repair alveolar bone resorption. This composite hydrogel has a simple preparation method and is inexpensive to produce, yet it has antibacterial and osteogenesis-promoting incremental effects, which makes it well suited for the treatment of periodontitis bone resorption, providing a new strategy for periodontal bone tissue engineering.

Abstract
OBJECTIVE The systematic review aimed to review the existing evidence, to identify and appraise the effectiveness of periodontal prevention and treatment modalities in individuals diagnosed with Down syndrome (DS) and to determine the estimates of the effects of implemented periodontal prevention and treatment strategies compared to chromosomally normal (CN) individuals. METHODOLOGY The systematic review was conducted and reported in conformity with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. The study protocol was registered in the Open Science Framework. Electronic and manual searches, in accordance with PICO framework and delineated inclusion/exclusion criteria, were conducted in multiple databases. RESULTS The initial search identified 11,704 studies. After removing duplicates, 9,048 remained. Title and abstract screening narrowed these to 281 for full-text review. Ultimately, 16 studies met the inclusion criteria, with 4 eligible for quantitative data synthesis. Results of the meta-analysis indicated that professional tooth cleaning in combination with oral hygiene reinforcement was less effective in the reduction of PPD in patients with DS compared to those without DS (Mean difference (MD): 0.23; 95% Confidence Interval (CI): 0.14 to 0.32; p < 0.001). DISCUSSION These findings suggest that conventional periodontal treatment is less effective in managing periodontitis in patients with DS. Thus, tailored periodontal care strategies that address the specific needs of individuals with DS should be implemented to improve treatment outcomes for this population The presence of moderate to high risk of bias in the included studies underscores the need for rigorously designed research that minimizes bias through effective blinding, randomization, control of confounding factors, and inclusion of diverse treatment outcomes to further investigate these associations. CONCLUSION Based on the best available evidence, professional tooth cleaning combined with oral hygiene instructions appears to be less effective in reducing pocket depths in individuals with DS compared to those without DS. https://doi.org/10.17605/OSF.IO/UXTCG.

Abstract
OBJECTIVES To investigate the effect of osteoblast-derived extracellular vesicles (OB-EVs) on the proliferation and differentiation of osteoclasts, and to explore the possible molecular mechanism of extracellular vesicles involved in the communication between osteoblasts and osteoclasts. METHODS Primary osteoblasts were isolated from newborn mouse calvarial bone and induced by β-glycero phosphate, ascorbic acid and dexamethasone. Osteogenic feature was tested by alkaline phosphatase (ALP) and alizarin red S staining. Extracellular vesicles were isolated by ultracentrifugation from the cell culture supernatant. Vesicle morphology was observed by transmission electron microscopy, and the characteristic markers of tumor susceptibility gene 101 (TSG101), ALG-2 interacting protein X (Alix) and cluster of differentiation 9 (CD9) on the surface of extracellular vesicles were identified by Western blotting. Cell counting kit 8 (CCK-8) assay was used to determine the proliferation effect of OB-EVs on mouse mononuclear macrophage RAW264.7 cells. Furthermore, the expression level of specific markers of osteoclast differentiation in RAW264.7 cells was detected by Western blotting after the combined effect of OB-EVs and receptor activator for nuclear factor κB ligand (RANKL). The number of osteoclasts was observed and compared with OB-EVs-treated mouse bone marrow-derived macrophages (BMMs) by tartrate-resistant acid phosphatase (TRAP) staining, and the effect of OB-EVs on osteoclast differentiation was determined. RESULTS The extracted OB-EVs showed a double-layer cup-like structure with a diameter of 30-150 nm, and TSG101, Alix and CD9 were expressed. RAW264.7 cells were stimulated with OB-EVs, and the results of CCK-8 assay showed that high concentration of OB-EVs (more than 20 μg/mL) inhibited cell proliferation (P<0.05). Western blotting analysis showed that the expression of osteoclast differentiation marker proteins such as c-Fos, activated T cell nuclear factor (NFATc1) and c-Jun N-terminal kinase (JNK) in RAW264.7 cells were significantly increased, and the promoting effect was enhanced with increasing of OB-EVs concentration (P<0.05). In addition, the combination of OB-EVs and RANKL on BMMs showed that the number of TRAP-positive cells was significantly higher than that of the RANKL induction group alone (P<0.05). CONCLUSIONS OB-EVs can promote the differentiation of osteoclast precursor cells into osteoclasts, but high concentration of OB-EVs can inhibit proliferation of RAW264.7 cells.

Int Immunopharmacol 2024; 141:112933. [PMID: 39186834 DOI: 10.1016/j.intimp.2024.112933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2024] [Revised: 07/27/2024] [Accepted: 08/11/2024] [Indexed: 08/28/2024]
Abstract
Periodontitis is a chronic inflammatory disease that affects about 45 %-50 % of adults worldwide, but the efficacy of current clinical therapies is unsatisfactory due to the complicated periodontal immune microenvironment. Thus, developing drugs that can regulate innate immune cells (e.g., macrophages) is a potent strategy to treat periodontitis. Here, we report that phloretin, a food plant-derived natural compound, is sufficient to alleviate periodontitis through immune regulation. In vivo, phloretin treatment could significantly reduce alveolar bone resorption and periodontal inflammation in mouse periodontitis models. In vitro, phloretin could suppress proinflammatory (M1-like) polarization and cytokine release in macrophages induced by LPS. Mechanistically, the immune regulatory role of phloretin in macrophages may be due to its metabolic regulation effect. Phloretin might restore the balance of M1/M2 macrophage transition in periodontitis by inhibiting HIF-1α-mediated glycolysis and PI3k/Akt pathways, thereby reducing the proinflammatory effect and immune disorder caused by over-activated M1 macrophages. Together, this study highlights that natural compound, such as phloretin, can restore periodontal immune homeostasis by metabolic regulation of macrophages, which may provide novel insight into the treatment of periodontitis.

Abstract
OBJECTIVE Dental implants show impressive survival and like rates, but peri-implantitis is a frequent inflammatory disease which affects the implant-surrounding tissues. While biofilms on the implant surface is considered its etiologic reason, several risk factors determine the pace of progression of peri-implant bone loss. Some risk factors are generally accepted while others are still unconfirmed and a matter of ongoing discussion. Among the latter, tissue macrophage sensitization on TiO2 has gained scientific interest in recent years. The aim of the present case-control study was to test for potential associations between clinically manifest peri-implantitis and MS related parameters. MATERIALS AND METHODS In patients with implants affected by peri-implantitis in the test group and healthy implants in the control group clinical parameters (peri-implant pocket depths (PPD) and bleeding on probing (BOP) were measured. Samples of aMMP-8 were taken from the entrance of the peri-implant sulcus and bacterial samples were collected from the sulcus. Blood samples were obtained from the basilic vein to assess MA-related laboratory parameters. Potential correlations between clinical and laboratory parameters were tested by multiple regression (p < 0.05). RESULTS No statistically significant correlations were found between clinical or bacteriological findings and laboratory parameters were found. CONCLUSIONS Based on the findings of this study elevated MA-related laboratory parameters do not appear to be linked to peri-implantitis. CLINICAL RELEVANCE Sensitization on TiO2 is not associated with clinical symptoms of peri-implantitis.

Abstract
BACKGROUND Bone loss of residual alveolar ridges is a great challenge in the field of dental implantology. Deproteinized bovine bone mineral (DBBM) is commonly used for bone regeneration, however, it is loose and difficult to handle in clinical practice. Hyaluronic acid (HA) shows viscoelasticity, permeability and excellent biocompatibility. The aim of this study is to evaluate whether high-molecular-weight (MW) HA combined with DBBM could promote new bone formation in rat calvarial critical size defects (CSDs). MATERIALS AND METHODS Rat calvarial CSDs (5 mm in diameter) were created. Rats (n = 45) were randomly divided into 3 groups: HA-DBBM compound grafting group, DBBM particles only grafting group and no graft group. Defect healing was assessed by hematoxylin-eosin staining and histomorphometry 2, 4 and 8 weeks postop, followed by Micro-CT scanning 8 weeks postop. Statistical analyses were performed by ANOVA followed by Tukey's post hoc test with P < 0.05 indicating statistical significance. RESULTS All rats survived after surgery. Histomorphometric evaluation revealed that at 2, 4 and 8 weeks postop, the percentage of newly formed bone was significantly greater in HA-DBBM compound grafting group than in the other two groups. Consistently, Micro-CT assessment revealed significantly more trabecular bone (BV/TV and Tb.N) in HA-DBBM compound group than in the other two groups, respectively (P < 0.05). Moreover, the trabecular bone was significantly more continuous (Tb.Pf) in HA-DBBM compound group than in the other two groups, respectively (P < 0.05). CONCLUSION HA not only significantly promoted new bone formation in rats calvarial CSDs but also improved the handling ability of DBBM.

Abstract
Regenerating inflamed bone defects represents a severe clinical challenge due to the undesirable inflammatory microenvironment. The inflammatory stimulus poses a weighty threat to the regenerative capacity of endogenously derived mesenchymal stem cells (MSCs), which are mainly responsible for osteogenic differentiation, thereby resulting in compromised endogenous bone formation. Consequently, alleviating the biological characteristics of inflammatory-impaired MSCs is crucial for promoting inflamed bone regeneration. Nano-sized small extracellular vesicles (sEVs) have emerged as promising therapeutic tools to orchestrate MSCs fate due to their intrinsic biocompatibility and encapsulated bioactive contents. In the present study, we extracted sEVs from youthful and adult dental pulp MSCs and explored their ability to recover inflammation-compromised periodontal ligament stem cells (IPDLSCs). The results indicated that both types of sEVs were capable of facilitating IPDLSCs osteogenesis. However, young sEVs exhibited a more robust potential at a lower concentration compared to adult sEVs. Mechanically, young sEVs enhanced the expression of bone morphogenetic protein 4 (BMP4) via delivering the protein Biglycan, which correspondingly promoted the osteogenic capability of IPDLSCs. Collectively, our findings emphasized that young sEVs hold enormous potential to rescue the inherent function and regenerative competence of inflammation-impaired MSCs, shedding light on their promising therapeutic prospects for infected bone regeneration.

Abstract
BACKGROUND Periodontitis is the sixth-most common disease worldwide. The oral microbiome composition and its association with Periodontal disease (PD) have been largely explored; however, limited studies have explored the microbial profiles of both oral and toothbrushes in patients with PD. Thus, this study aimed to ascertain the oral and toothbrushes microbial composition in high-altitude populations, hypothesizing that their correlation with periodontal health would differ from those at lower altitudes, potentially indicating links between environmental factors, microbial colonization patterns, and periodontal health in distinct geographic contexts. METHODS In the present study, we enrolled 35 individuals including 21 healthy and 14 diagnosed with PD from the Lhasa region of Tibet, China. Saliva and toothbrush samples were collected from each participant to assess the association between toothbrush usage and oral microbiome with PD using 16 S rRNA gene-specific V3-V4 regions sequencing. To assess the oral and toothbrush microbiome composition and diversity and its possible link to PD. RESULTS Significantly higher Alpha diversity (Shannon index) was observed between the PD group and PD toothbrushes (p = 0.00021) and between the PD group and Healthy toothbrushes (p = 0.00041). The predominant species were Proteobacteria, Bacteroidota, Firmicutes, Actinobacteria, and Fusobacteria, with genera Pseudomonas, Veillonella, Neisseria, Acinetobacter, and Haemophilus. In addition, PICRUST2 analysis unveiled 44 significant pathways differentiating the disease and healthy groups, along with 29 pathways showing significant differences between their respective toothbrush microbial profiles. The distinct oral and toothbrush microbial composition among high-altitude populations suggests potential adaptations to the challenges of high-altitude environments. CONCLUSION This study emphasizes the importance of tailored dental care strategies, accounting for altitude and racial factors, to effectively manage periodontal health in these communities. Further research is warranted to investigate the specific microbial mechanisms and develop targeted interventions for optimizing oral health in populations across varying altitudes.

Abstract
Autogenous dentin matrix (ADM), derived from a patient's extracted tooth, can be repurposed as an autologous grafting material in reconstructive dentistry. Extracted teeth provide a source for ADM, which distinguishes itself with its low rejection rate, osteoinductive capabilities and ease of preparation. Consequently, it presents a viable alternative to autogenous bone. Animal studies have substantiated its effective osteoinductive properties, while its clinical applications encompass post-extraction site preservation, maxillary sinus floor augmentation, and guided bone tissue regeneration. Nevertheless, the long-term efficacy of ADM applied in bone regeneration remains underexplored and there is a lack of standardization in the preparation processes. This paper comprehensively explores the composition, mechanisms underlying osteoinductivity, preparation methods, and clinical applications of ADM with the aim of establishing a fundamental reference for future studies on this subject.

Abstract
OBJECTIVE The aim of this non-inferiority randomized clinical trial was to compare the surgical and healing complications, vertical bone gain, and volumetric bone changes after vertical ridge augmentation using two different approaches: customized Ti-reinforced d-PTFE mesh versus customized CAD/CAM Ti-mesh. MATERIALS AND METHODS Fifty patients with vertical bone defects were randomly treated with Ti-reinforced d-PTFE mesh (control group) or CAD/CAM Ti-mesh (test group) and a mix of autogenous bone and deproteinized bovine bone matrix. Surgical and healing complication rates (SCR-HCR), vertical bone gain (VBG), regenerated bone volume (RBV), and regeneration rates (RR and ERR) were recorded and analysed [significance level (α) of 0.05]. RESULTS Of the 50 patients, 48 underwent bone augmentation surgery. SCR were 4% and 12% in PTFE and Ti-mesh, whereas HCR were 12.5% and 8.3%. VBG were 5.79 ± 1.71 mm (range: 3.2-8.8 mm) in the PTFE group and 5.18 ± 1.61 mm (range: 3.1-8.0 mm) in the Ti-mesh group (p = .233), whereas RBV were 1.46 ± 0.48 cc and 1.26 ± 0.55. RR was 99.5% and 87.0%, demonstrating a statistically significant difference (p = .013). Finally, the values related to pseudo-periosteum, bone density, and implant stability were similar in the two study groups. Osseointegration rates were 98.2% and 98.3%. CONCLUSIONS This study confirmed the non-inferiority of customized CAD/CAM titanium meshes with respect to reinforced PTFE meshes in terms of surgical and healing complications. Although PTFE meshes showed higher vertical bone gain and regeneration rates than Ti-meshes, no significant differences were found.

Abstract
An aged immune system undergoes substantial changes where myelopoiesis dominates within the bone marrow. Monocytic-MDSCs (M-MDSCs) have been found to play an important role in osteoclastogenesis and bone resorption. In this study, we sought to provide a more comprehensive understanding of the osteoclastogenic potential of bone marrow M-MDSCs during normal aging through transcriptomic and metabolic changes. Using young mature and aged mice, detailed immunophenotypic analyses of myeloid cells revealed that the M-MDSCs were not increased in bone marrow, however M-MDSCS were significantly expanded in peripheral tissues. Although aged mice exhibited a similar number of M-MDSCs in bone marrow, these M-MDSCs had significantly higher osteoclastogenic potential and greater demineralization activity. Intriguingly, osteoclast progenitors from aged bone marrow M-MDSCs exhibited greater mitochondrial respiration rate and glucose metabolism. Further, transcriptomic analyses revealed the upregulation of mitochondrial oxidative phosphorylation and glucose metabolism genes. Interestingly, there was 8-fold increase in Cd38 mRNA gene expression, consistent with the Mouse Aging Cell Atlas transcriptomic database, and confirmed by qRT-PCR. CD38 regulates NAD+ availability, and 78c, a small molecule inhibitor of CD38, reduced the mitochondrial oxygen consumption rate and glucose metabolism and inhibited the osteoclastogenic potential of aged mice bone marrow-derived M-MDSCs. These results indicate that the age-related increase in Cd38 expression in M-MDSCs bias the transcriptome of M-MDSCs towards osteoclastogenesis. This enhanced understanding of the mechanistic underpinnings of M-MDSCs and their osteoclastogenesis during aging could lead to new therapeutic approaches for age-related bone loss and promote healthy aging.

Abstract
OBJECTIVE Estimate the impact of Adiponectin receptors agonist (AdipoRon) on dental implant osseointegration in alveolar bone and explore the possible mechanism between saliva microbiota and AdipoRon in diabetic mice. MATERIALS AND METHODS Sixty C57BL/6 mice (male, 8 weeks old) were divided randomly into four groups according to different doses of AdipoRon: normoglycemic control group; DM control group; DM with a low dose of AdipoRon (5 mg/kg/day); and DM with a high dose of AdipoRon (50 mg/kg/day). Then, dental implants were placed in the palatal root socket in the first molar extraction mouse model. Micro-computed tomography, histology examination, immunohistochemical staining, and oral microbiota were explored to evaluate implant osseointegration. RESULTS AdipoRon treatment at 50 mg/kg markedly promoted dental implant osseointegration in diabetic mice, but AdipoRon treatment at 5 mg/kg was not effective. Moreover, distinct differences in the oral microbiota composition were shown between the diabetic mice and diabetic mice treated with AdipoRon at 50 mg/kg. CONCLUSION AdipoRon treatment at 50 mg/kg in diabetic mice could significantly increase dental implant osseointegration. The salivary microbiota might participate in the accelerated osseointegration progress of dental implants in AdipoRon treatment.

Investigation of the mechanism of baicalein in the treatment of periodontitis based on network pharmacology, molecular docking and experimental validation. BMC Oral Health 2024; 24:987. [PMID: 39180042 PMCID: PMC11344467 DOI: 10.1186/s12903-024-04740-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 08/13/2024] [Indexed: 08/26/2024] Open
Abstract
PURPOSE To verify the effect and mechanism of baicalein in the treatment of periodontitis through network pharmacology, molecular docking and in vitro experiments. METHODS Firstly, multiple databases were used to predict targets of baicalein and periodontitis. And the screened key target genes of baicalein for treating periodontitis were subjected to GO and KEGG analysis; then these targets were analyzed by molecular docking techniques. In vitro experiments including CCK-8, RT-qPCR, ELISA and Immunofluorescence were conducted to validate the efficacy of baicalein in treating periodontitis. RESULTS Seventeen key targets were screened from the databases, GO and KEGG analysis of these targets revealed that baicalein may exert therapeutic effects through regulating TNF, PI3K-Akt, HIF-1 and other signaling pathways. Molecular docking analysis showed that baicalein has good binding potential to several targets. In vitro cellular assays showed that baicalein inhibited the expression of TNF-α, MMP-9, IL-6 and MCP1 in P.g-LPS-induced macrophages at both the mRNA and protein level. And the immunofluorescence intensity of iNOS, a marker of M1 type macrophages, which mainly secretes inflammatory factors, was significantly reduced. CONCLUSION Baicalein has the characteristics and advantages of "multicomponent, multitarget, and multipathway" in the treatment of periodontitis. In vitro cellular assays further confirmed the inhibitory effect of baicalein on the secretion of inflammatory factors of macrophages in periodontitis models, providing a theoretical basis for further study of the material basis and molecular mechanism of baicalein in the treatment of periodontal diseases.

Abstract
Alzheimer's disease (AD) stands as the predominant form of dementia, presenting significant and escalating global challenges. Its etiology is intricate and diverse, stemming from a combination of factors such as aging, genetics, and environment. Our current understanding of AD pathologies involves various hypotheses, such as the cholinergic, amyloid, tau protein, inflammatory, oxidative stress, metal ion, glutamate excitotoxicity, microbiota-gut-brain axis, and abnormal autophagy. Nonetheless, unraveling the interplay among these pathological aspects and pinpointing the primary initiators of AD require further elucidation and validation. In the past decades, most clinical drugs have been discontinued due to limited effectiveness or adverse effects. Presently, available drugs primarily offer symptomatic relief and often accompanied by undesirable side effects. However, recent approvals of aducanumab (1) and lecanemab (2) by the Food and Drug Administration (FDA) present the potential in disrease-modifying effects. Nevertheless, the long-term efficacy and safety of these drugs need further validation. Consequently, the quest for safer and more effective AD drugs persists as a formidable and pressing task. This review discusses the current understanding of AD pathogenesis, advances in diagnostic biomarkers, the latest updates of clinical trials, and emerging technologies for AD drug development. We highlight recent progress in the discovery of selective inhibitors, dual-target inhibitors, allosteric modulators, covalent inhibitors, proteolysis-targeting chimeras (PROTACs), and protein-protein interaction (PPI) modulators. Our goal is to provide insights into the prospective development and clinical application of novel AD drugs.

Abstract
OBJECTIVES Oral diseases, such as dental caries, periodontitis, and oral cancers, are highly prevalent worldwide. Many oral diseases are typically associated with bacterial infections or the proliferation of malignant cells, and they are usually located superficially. MATERIALS AND METHODS Articles were retrieved from PubMed/Medline, Web of Science. All studies focusing on stimuli-responsive materials in oral diseases were included and carefully evaluated. RESULTS Stimulus-responsive materials are innovative materials that selectively undergo structural changes and trigger drug release based on shifts at the molecular level, such as changes in pH, electric field, magnetic field, or light in the surrounding environment. These changes lead to alterations in the properties of the materials at the macro- or microscopic level. Consequently, stimuli-responsive materials are particularly suitable for treating superficial site diseases and have found extensive applications in antibacterial and anticancer therapies. These characteristics make them convenient and effective for addressing oral diseases. CONCLUSIONS This review aimed to summarize the classification, mechanism of action, and application of stimuli-responsive materials in the treatment of oral diseases, point out the existing limitations, and speculate the prospects for clinical applications. CLINICAL RELEVANCE Our findings may provide useful information of stimuli-responsive materials in oral diseases for dental clinicians.

Abstract
BACKGROUND The presence of a polymicrobial dysbiotic film in direct and constant contact with periodontal tissues initiates the host immune response. Interleukin 18 (IL-18) triggers up-regulates the production of other proinflammatory cytokines (TNF-α, IL-1β, IL-6), creating a vicious cycle that expands the inflammatory and destructive process in the periodontal tissue. A systematic review and meta-analysis was carried out with the main propose to investigate IL-18 expression in different biological samples from subjects with chronic periodontitis. METHODS The protocol followed PRISMA guidelines and was registered in Open Science Framework (OSF): https://doi.org/10.17605/OSF.IO/BS9GM . A digital search was conducted in the databases PubMed, ScienceDirect, Google Scholar, Web of Science and Dentistry & Oral Sciences Source databases were consulted from March 15th, 2005 to February 10th, 2023. Study quality was assessed using the JBI tool for cross-sectional studies and clinical trials. A meta-analysis was performed using a random/fixed effects model to evaluate the concentration of IL-18 in serum, plasma, saliva, gingival tissue and GCF of exposure group compared to control group. RESULTS The search strategy provided a total of 3,156 articles, of which 18 investigations met the inclusion criteria and 15 articles were quantitatively analyzed. The total number of patients studied was 1,275 (682 cases and 593 controls). The meta-analysis revealed significantly elevated IL-18 levels of serum, saliva and GCF of subjects with chronic periodontitis compared to healthy subjects (Serum: SMD = 62.73, 95%CI: 25.43-100.03, Z = 3.29, p = 0.001*; Saliva: SMD = 243.63, 95%CI: 8.68-478.59, Z = 2.03, p = 0.042*; GCF: SMD = 150.26, 95%CI: 56.86-243.66, Z = 3.15, p = 0.02*). CONCLUSION IL-18 levels in serum, saliva and GCF could have the potential to be used as complementary diagnostic tools to the clinical and radiographic parameters in subjects with periodontitis.

Abstract
Periodontitis is a chronic inflammatory oral disease that impaired the tooth-supporting apparatus, including gingival tissue destruction and alveolar bone resorption. The initiation of periodontitis is linked to the presence of oral bacteria, particularly P. gingivalis within pathogenic biofilms. Here, we demonstrated the central role of the autophagy regulator Transcription Factor EB (TFEB) in orchestrating autophagy activation and modulating the host immune response against P. gingivalis in periodontitis. Upregulation of TFEB expression at the protein level and heightened nuclear localization occurred during the progressive stages of periodontitis. Functionally, TFEB overexpression emerges as a potent alleviator of periodontitis-associated phenotypes, operating through the activation of autophagy and the inhibition of the NF-κB pathway in both in vivo and in vitro models. In addition, TFEB knockdown exacerbates the inflammatory response by upregulating pro-inflammatory cytokines. The dual regulatory role of TFEB in governing both autophagy and inflammatory responses unveils novel insights into periodontitis pathogenesis, positioning TFEB as a promising therapeutic target for periodontitis intervention.

Abstract
Endoscopic tattooing is a localization technique that is particularly important for identifying gastrointestinal lesions for follow-up and subsequent treatment. However, the dyes currently used for endoscopic tattooing have a short tattooing time, high cost, and many side effects. Herein, we designed and prepared polydopamine (PDA) nanoparticles modified with polyvinylpyrrolidone (PVP) for endoscopic tattooing using a physical encapsulation method. PDA has good stability and high adhesion properties, and its stability was further enhanced after PVP modification. In vitro and in vivo tests demonstrated that PDA/PVP has good biosafety. Endoscopic tattooing with PDA/PVP in a porcine model showed that the dye could be stabilized in the digestive tract for at least 60 days. Furthermore, our research results demonstrated that PDA/PVP has excellent reactive oxygen species (ROS) and reactive nitrogen species (RNS) scavenging ability and can promote wound healing. Overall, the strategy proposed herein will lead to the use of an innovative dye for endoscopic tattooing of gastrointestinal lesions.

Abstract
OBJECTIVES The present parallel randomized clinical trial aimed to assess, after a 3-year follow-up period, whether the choice of surgical technique-either manual or digitally static guided-and of the operator - non-expert operator or skilled operator- affects the stability of peri-implant marginal bone levels in implants placed 1 mm sub-crestal. MATERIALS AND METHODS Patients received platform-switched implants (Anyridge, MegaGen Implant Co., Gyeongbuk, South Korea) featuring a 5-degree internal conical connection and supporting single screw-retained fixed crowns. The implants were randomly assigned to be placed through a digitally static guided surgery procedure (Test group - GS) or a freehand surgical technique (Control Group - FH). A non-expert operator (fewer than 20 implants placed in their professional activity) was selected to perform procedures for the GS Group, while a skilled operator (with over 1000 implants placed in their professional activity) was chosen for the FH Group. Marginal bone level (MBL) was measured at prosthesis installation (t0) and 1 (t1), 2 (t2) and 3 years (t3) of follow-up. Changes in MBL from t0 to t3 were analyzed through periapical radiographs. Moreover, MBL changes at all time points were correlated to different supra-crestal soft tissue heights (STH): less than 3 and ≥ 3mm, respectively. RESULTS 60 implants in 18 patients were examined, with 30 implants allocated to the GS group and 30 to the FH group. The difference in MBL change between the two groups was 0.11 ± 0.22 mm, which was not statistically significant (p=0.61). At the time of prosthetic loading, the mean MBL for implants with STH less than 3mm was 0.33mm higher than implants with STH ≥ 3mm, though this difference was not statistically significant (P=0.065). CONCLUSIONS Digitally static guided implant placement, performed by a non-expert operator, does not limit marginal bone remodeling, when compared to a freehand procedure performed by an experienced operator. CLINICAL SIGNIFICANCE After correct and careful planning, early marginal bone levels (MBL) around conical connection, platform-switched implants placed sub-crestally may be stable in time. Digital planning and surgery have the potential to assist non-expert clinicians in achieving implant placements with comparable outcomes to those performed by experts.

Abstract
OBJECTIVES To investigate the effect of adiposity status, salivary physicochemical parameters, and inflammatory biomarkers on the salivary abundance of the two main cariogenic bacteria Streptococcus mutans and Streptococcus sobrinus among Hong Kong adolescents. SUBJECTS AND METHODS This study included 180 adolescents aged 12-15 years from Hong Kong local secondary schools. Anthropometric measurements and oral health examinations were performed. Saliva samples were collected to measure salivary physicochemical parameters, protein biomarker levels, and salivary abundance of Streptococcus mutans, Streptococcus sobrinus, and total bacteria. RESULTS Adolescents with general overweight/obesity or central obesity had significantly higher salivary Streptococcus mutans abundance and total bacterial load, lower stimulated salivary flow rate, and lower secretory phospholipase A2 group IIA levels than the lean controls. Adolescents with general overweight/obesity (OR = 3.33; 95% CI: 1.28-8.65) and those with central obesity (OR = 2.47; 95% CI: 1.02-6.00) had a significantly higher chance of having high salivary abundance of Streptococcus mutans than the lean controls after adjusting for confounders, with a similar detection rate of salivary Streptococcus sobrinus. CONCLUSION General overweight or obesity and central obesity were associated with a high salivary abundance of Streptococcus mutans but had no significant effect on salivary Streptococcus sobrinus.

An integrated preventive and therapeutic magnetic nanoparticle loaded with rhamnolipid and vancomycin for combating subgingival biofilms. Dent Mater 2024:S0109-5641(24)00253-7. [PMID: 39174419 DOI: 10.1016/j.dental.2024.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 08/05/2024] [Accepted: 08/15/2024] [Indexed: 08/24/2024]
Abstract
OBJECTIVES Mechanical debridement supplemented with antibacterial agents effectively eradicates subgingival biofilms formed in the periodontal pockets of severe periodontitis patients. However, the available antimicrobial agents have limited penetrating ability to kill the bacteria encased in the deep layers of biofilms. This study aimed to fabricate a novel magnetic nanoparticle (MNP) loaded with rhamnolipid (RL) and vancomycin (Vanc, Vanc/RL-Ag@Fe3O4) to combat subgingival biofilms. METHODS The multispecies subgingival biofilm was formed by periodontal pathogens, including Streptococcus oralis (S. oralis), Streptococcus sanguinis (S. sanguinis), Actinomyces naeslundii (A. naeslundii), Porphyromonas gingivalis (P. gingivalis) and Fusobacterium nucleatum (F. nucleatum). Scanning electron microscope (SEM), confocal laser scanning microscopy (CLSM), and quantitative real-time polymerase chain reaction (qRT-PCR) were used to determine the anti-biofilm efficacy of Vanc/RL-Ag@Fe3O4 with or without a magnetic field on multispecies subgingival biofilms. RESULTS The minimal inhibitory concentration (MIC) values of Vanc/RL-Ag@Fe3O4 on S. oralis, S. sanguinis, A. naeslundii, P. gingivalis, and F. nucleatum were 25, 50, 100, 50, and 25 μg/mL, respectively. Vanc/RL-Ag@Fe3O4 (200 μg/mL) reduced the 7-d biofilm thickness from 22 to 13 µm by degrading extracellular polymeric substance (EPS) and killing most bacteria except for tolerant F. nucleatum. A magnetic field enhanced the anti-biofilm effect of Vanc/RL-Ag@Fe3O4 by facilitating its penetration into the bottom layers of biofilms and killing tolerant F. nucleatum. SIGNIFICANCE Vanc/RL-Ag@Fe3O4 MNPs can release RL, Vanc, and Ag and eradicate subgingival biofilms by disrupting EPS and killing bacteria. Vanc/RL-Ag@Fe3O4 combined with a magnetic force is a promising approach for combating periodontal infection.

Abstract
OBJECTIVES The aim of this study was to quantitatively and comprehensively investigate the combined effects of arginine and fluoride on the suppression of pathogenicity using an in situ biofilm model and next-generation sequencing (NGS). METHODS Using the in situ model, dental biofilms were formed and the viable bacterial counts and arginine activity in the arginine- and fluoride-containing dentifrice and control groups were measured. We also compared their effects on the bacterial microbiota and predictive functional factors in the control, arginine (arg), and arginine + fluoride (argF) groups using NGS analysis. RESULTS Compared to the control treatment, the use of 8 % arginine and 1450 ppm fluoride toothpaste resulted in significantly high oral NH4+ concentrations without affecting the number of viable bacteria (P < 0.05). NGS analysis revealed that the oral microbiota of the control, arg, and argF groups were significantly different. Heat map analysis of the predicted functional factors revealed that the arg group had different properties from the other groups and activated specific substrate metabolic pathways; contrastingly, argF treatment inhibited the activity of these pathways and prevented an increase in the abundance of bacterial genera that utilize substrates such as sucrose, suggesting the synergistic effect of arginine and fluoride. CONCLUSIONS This study indicates that the combination of arginine and fluoride has a synergistic effect on the bacterial microbiota and pathogenicity of dental biofilms compared with arginine alone. CLINICAL SIGNIFICANCE Our findings suggest that the combination of arginine and fluoride could be used as an effective prebiotic and may inhibit the growth of bacteria associated with dental diseases.

Abstract
Biomineralization is a natural process in which organisms regulate the growth of inorganic minerals to form biominerals with unique layered structures, such as bones and teeth, primarily composed of calcium and phosphorus. Tooth decay significantly impacts our daily lives, and the key to tooth regeneration lies in restoring teeth through biomimetic approaches, utilizing mineralization strategies or materials that mimic natural processes. This review delves into the types, properties, and transformations of calcium and phosphorus minerals, followed by an exploration of the mechanisms behind physiological and pathological mineralization in living organisms. It summarizes the mechanisms and commonalities of biomineralization and discusses the advancements in dental biomineralization research, guided by insights into calcium and phosphorus mineral biomineralization. This review concludes by addressing the current challenges and future directions in the field of dental biomimetic mineralization.

Abstract
Guided bone regeneration (GBR) membranes play an important role in oral bone regeneration. However, enhancing their bone regeneration potential and antibacterial properties is crucial. Herein, silk fibroin (SF)/polycaprolactone (PCL) core-shell nanofibers loaded with epigallocatechin gallate (EGCG) were prepared using emulsion electrospinning. The nanofibrous membranes were characterized via scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, water contact angle (CA) measurement, mechanical properties testing, drug release kinetics, and 1,1-diphenyl-2-picryl-hydrazyl radical (DPPH) free radical scavenging assay. Mouse pre-osteoblast MC3T3-E1 cells were used to assess the biological characteristics, cytocompatibility, and osteogenic differentiation potential of the nanofibrous membrane. Additionally, the antibacterial properties againstStaphylococcus aureus (S. aureus)andEscherichia coli (E. coli)were evaluated. The nanofibers prepared by emulsion electrospinning exhibited a stable core-shell structure with a smooth and continuous surface. The tensile strength of the SF/PCL membrane loaded with EGCG was 3.88 ± 0.15 Mpa, the water CA was 50°, and the DPPH clearance rate at 24 h was 81.73% ± 0.07%. The EGCG release rate of membranes prepared by emulsion electrospinning was reduced by 12% within 72 h compared to that of membranes prepared via traditional electrospinning.In vitroexperiments indicate that the core-shell membranes loaded with EGCG demonstrated good cell compatibility and promoted adhesion, proliferation, and osteogenic differentiation of MC3T3-E1 cells. Furthermore, the EGCG-loaded membranes exhibited inhibitory effects onE. coliandS. aureus. These findings indicate that core-shell nanofibrous membranes encapsulated with EGCG prepared using emulsion electrospinning possess good antioxidant, osteogenic, and antibacterial properties, making them potential candidates for research in GBR materials.

Abstract
Fermented food consumption is recommended for health and environmental purposes. While it is known to impact gut microbiota, further investigation is needed to establish connections with the oral microbiota. For this purpose, we investigated the effect of daily consumption of a model cheese containing 3 Lactic Acid Bacteria (LAB) species on the oral microbiota of rats following a 3-week diet. Cheese consumption transiently modifies the oral microbiota and leads to a transient persistence of LAB in the oral cavity of 1/3 of the animals. The origin of this variability was partly explained by an overrepresentation of salivary proteins involved in the response to oxidative stress in animals without LAB persistence. These findings highlight the significance of fermented foods in shaping the diversity of the oral microbiota. Additionally, they suggest that variations in the salivary proteome among individuals may influence the permissiveness of the oral microbiota towards exogenous microorganisms.

Abstract
OBJECTIVES Toll-like receptor (TLR)-9, may play a role in periodontal disease inflammation. This study measured TLR-9 and its related molecules, absence in melanoma-2 (AIM-2) and Z-DNA-binding protein-1 (ZBP-1), in gingival crevicular fluid (GCF) from patients with varying stages of periodontal disease to assess the role of pathogen-derived nucleic acids in inflammation. MATERIALS AND METHODS The study comprised 80 participants: 20 with Stage III Grade C periodontitis, 20 with Stage III Grade B periodontitis (P-Stage III-B), 19 with gingivitis, and 21 with periodontal health. Parameters including probing depth (PD), clinical attachment level (CAL), plaque index (PI), and bleeding on probing (BOP) were recorded. ELISA was used to analyze TLR-9, AIM-2, and ZBP-1 levels in GCF. Nonparametric tests were used for statistical comparisons. RESULTS The total amount of TLR-9 was higher in P-Stage III-B than in the healthy group (p < 0.05). Similarly, the gingivitis group exhibited elevated GCF TLR-9 levels compared to the healthy group (p < 0.05). GCF AIM-2 and ZBP-1 levels remained consistent across groups (p > 0.05). Significant correlations were found between GCF TLR-9 and CAL (p < 0.05), BOP (p < 0.05), PI (p < 0.01), and GCF volume (p < 0.001). CONCLUSION These findings suggested that the TLR-9-mediated inflammatory process plays a role in periodontal disease, as evidenced by the increased levels of TLR-9 in GCF.

Abstract
AIMS Periodontitis and cardiovascular diseases (CVD) are highly prevalent non-communicable diseases, sharing an inflammatory pathogenesis and common risk factors. The objective of the present research is to assess the association between periodontitis and cardiovascular disease risk in a representative sample of the Spanish-employed population. METHODS Cross-sectional data were obtained between 2008 and 2011 in the Workers' Oral Health (WORALTH) epidemiological study. Periodontal examinations were based on the evaluation of clinical attachment loss (CAL) and community periodontal index (CPI). Participants also underwent a medical check-up and answered a comprehensive health questionnaire. With this information, participants were categorized into three levels of CVD risk using the systemic coronary risk estimation (SCORE) algorithm for low-risk European countries. Crude and adjusted odds ratios (ORs) were determined with multiple logistic regression models for the association between periodontal status and CVD risk. RESULTS Data from 4224 individuals were analyzed. The overall prevalence of high CVD risk (SCORE ≥ 5%) was 5.1%. The prevalence of SCORE ≥ 5% was 3.4%, 9.4%, and 15.2% for CAL 0-3 mm, 4-5 mm, and ≥6 mm, respectively (p < .001), and 6.2%, 6.5%, and 14.6% for CPI ≤2, 3, and 4, respectively (p < .001). Individuals with CPI = 4 presented an OR of 1.50 (95% confidence interval, CI [1.04; 2.17]) for high SCORE values, after adjusting for confounders (age, sex, and smoking habit). CONCLUSIONS Periodontitis, defined by the presence of deep periodontal pockets (≥6 mm), was significantly associated with high CVD risk (SCORE ≥ 5%) in a representative sample of the employed population in Spain.
