Abstract
BACKGROUND Oral inflammatory diseases are localized infectious diseases primarily caused by oral pathogens with the potential for serious systemic complications. However, publicly available datasets for these diseases are underutilized. To address this issue, a web tool called OralExplorer was developed. This tool integrates the available data and provides comprehensive online bioinformatic analysis. METHODS Human oral inflammatory disease-related datasets were obtained from the GEO database and normalized using a standardized process. Transcriptome data were then subjected to differential gene expression analysis, immune infiltration analysis, correlation analysis, pathway enrichment analysis, and visualization. The single-cell sequencing data was visualized as cluster plot, feature plot, and heatmaps. The web platform was primarily built using Shiny. The biomarkers identified in OralExplorer were validated using local clinical samples through qPCR and IHC. RESULTS A total of 35 human oral inflammatory disease-related datasets, covering 6 main disease types and 901 samples, were included in the study to identify potential molecular signatures of the mechanisms of oral diseases. OralExplorer consists of 5 main analysis modules (differential gene expression analysis, immune infiltration analysis, correlation analysis, pathway enrichment analysis and single-cell analysis), with multiple visualization options. The platform offers a simple and intuitive interface, high-quality images for visualization, and detailed analysis results tables for easy access by users. Six markers (IL1β, SRGN, CXCR1, FGR, ARHGEF2, and PTAFR) were identified by OralExplorer. qPCR- and IHC-based experimental validation showed significantly higher levels of these genes in the periodontitis group. CONCLUSIONS OralExplorer is a comprehensive analytical platform for oral inflammatory diseases. It allows users to interactively explore the molecular mechanisms underlying the action and regression of these diseases. It also aids dental researchers in unlocking the potential value of transcriptomics data related to oral diseases. OralExplorer can be accessed at https://smuonco.shinyapps.io/OralExplorer/ (Alternate URL: http://robinl-lab.com/OralExplorer ).

Abstract
Introduction Periodontal disease is the inflammation of the periodontium tissues surrounding the teeth, potentially leading to loss of tooth attachment. In individuals with periodontal disease, the presence of Trichomonas tenax, a parasitic protozoan of the oral cavity has been observed and its frequency tends to rise as the disease progresses. Methods A literature search was conducted in the online databases of PubMed, Google Scholar, Web of Science, and Scopus using the combination of keywords: "Trichomonas tenax" AND "periodontal disease" OR "gum disease", OR "oral disease" OR "periodontitis". A total of 9 articles satisfied the inclusion criteria and were included in this study. Results This review highlights the incidence of T. tenax with periodontal diseases, the risk factors that contribute to the infection of T. tenax and available detection methods for the identification of the protozoan. Conclusion The inhabitation of the oral cavity by T. tenax prospers with the severity of periodontal diseases. Extensive research should be conducted to fully understand the potential pathogenic role and damaging effect of T. tenax in the oral cavity.

Abstract
Treating oral diseases remains challenging as API is quickly washed out of the application site by saliva turnover and mouth movements. In situ gels are a class of application forms that present sol-gel transition's ability as a response to stimuli. Their tunable properties are provided using smart polymers responsible for stimuli sensitivity, often providing mucoadhesivity. In this study, antimicrobial in situ gels of thermosensitive and pH-sensitive polymers loaded with silver nanoparticles were prepared and evaluated. The nanoparticles were prepared by green synthesis using Agrimonia eupatoria L. extract. According to the data analysis, the in situ gel with the most promising profile contained 15 % of Pluronic® F-127, 0.25 % of methylcellulose, and 0.1 % of Noveon® AA-1. Pluronic® F-127 and methylcellulose significantly increased the viscosity of in situ gels at 37 °C and shear rates similar to speaking and swallowing. At 20 °C, a behavior close to a Newtonian fluid was observed while being easily injectable (injection force 13.455 ± 1.973 N). The viscosity of the formulation increased with temperature and reached 2962.77 ± 63.37 mPa·s (37 °C). A temperature increase led to increased adhesiveness and rigidity of the formulation. The critical sol-gel transition temperature at physiological pH was 32.65 ± 0.35 °C. 96.77 ± 3.26 % of Ag NPs were released by erosion and dissolution of the gel after 40 min. The determination of MIC showed effect against E. coli and S. aureus (0.0625 mM and 0.5000 mM, respectively). The relative inhibition zone diameter of the in situ gel was 73.32 ± 11.06 % compared to gentamicin sulfate. This work discusses the optimization of the formulation of novel antibacterial in situ gel for oromucosal delivery, analyses the impact of the concentration of excipients on the dependent variables, and suggests appropriate evaluation of the formulation in terms of its indication. This study offers a promising dosage form for local treatment of oral diseases.

Abstract
OBJECTIVES Method-dependent comparison of antimicrobial agents' efficacy against oral pathogens. MATERIALS AND METHODS Several sodium hypochlorite solutions (NaOCl)-Perisolv®, Carisolv® and Dakin's solution-were equated with chlorhexidine (CHX) and hydrogen peroxide (H2O2) against ten oral micro-organisms related to caries and periodontitis using different minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) techniques. Agents were adjusted to the final 70 mmol/L concentration of active chlorine molecule. RESULTS Apart from H2O2 and the amino acids of Perisolv®, all the agents revealed an antimicrobial effect. Agar diffusion test ranked CHX (p < 0.05) as the most effective against all ten specimens, followed by the NaOCl of Perisolv® and Dakin's solution. Correspondingly, in broth microdilution on agar, CHX was the most effective in eradicating micro-organisms at 0.03 mmol/L compared with 2.2 mmol/L of Dakin's solution. In contrast, the bactericidal concentration of Dakin's solution was the most effective at 0.2 mmol/L, (p < 0.001), followed by Perisolv® (2.14 mmol/L), CHX (2.38 mmol/L) and Carisolv® (3.33 mmol/L) after 5 and 10 min in broth dilution test. In live/dead analysis, 60-min exposure to a 2-fold concentration of agents resulted in two-log Aggregatibacter actinomycetemcomitans inhibition by CHX (35 mmol/L) whilst Streptococcus mutans was more susceptible, in 0.8 and 8.8 mmol/L, after 10 min to CHX and Dakin's respectively. CONCLUSION Replacement of CHX with tested hypochlorite agents showed evident potential and promoted rapid antimicrobial effect. CLINICAL RELEVANCE Effective antimicrobial agents are crucial in controlling pathogen-induced oral infections increasing clinical possibilities to combat oral biofilms. Additionally, CHX substitution with hypochlorite agents could eliminate CHX's adverse effects.

Abstract
IL-33 is a relatively new member of the IL-1 cytokine family, which plays a unique role in autoimmune diseases, particularly some oral diseases dominated by immune factors. The IL-33/ST2 axis is the main pathway by which IL-33 signals affect downstream cells to produce an inflammatory response or tissue repair. As a newly discovered pro-inflammatory cytokine, IL-33 can participate in the pathogenesis of autoimmune oral diseases such as Sjogren's syndrome and Behcet's disease. Moreover, the IL-33/ST2 axis also recruits and activates mast cells in periodontitis, producing inflammatory chemokines and mediating gingival inflammation and alveolar bone destruction. Interestingly, the high expression of IL-33 in the alveolar bone, which exhibits anti-osteoclast effects under appropriate mechanical loading, also confirms its dual role of destruction and repair in an immune-mediated periodontal environment. This study reviewed the biological effects of IL-33 in autoimmune oral diseases, periodontitis and periodontal bone metabolism, and elaborated its potential role and impact as a disease enhancer or a repair factor.

Abstract
Saliva is a versatile biofluid that contains a wide variety of biomarkers reflecting both physiologic and pathophysiologic states. Saliva collection is noninvasive and highly applicable for tests requiring serial sampling. Furthermore, advances in test accuracy, sensitivity and precision for saliva has improved diagnostic performance as well as the identification of novel markers especially in oral disease processes. These include dental caries, periodontitis, oral squamous cell carcinoma (OSCC) and Sjögren's syndrome (SS). Numerous growth factors, enzymes, interleukins and cytokines have been identified and are the subject of much research investigation. This review highlights current procedures for successful determination of saliva biomarkers including preanalytical factors associated with sampling, storage and pretreatment as well as subsequent analysis. Moreover, it provides an overview of the diagnostic applications of these salivary biomarkers in common oral diseases.

Abstract
Background This work performs a literature review of photoacoustic imaging (PAI) in dentistry and discusses the development of PAI in relation to oral health. Methods A search method was used to locate papers published between 2011 and 2023 in Google Scholar and PubMed databases, and 25 studies were selected. Reports on PAI in dentistry were included. Articles not written in English or whose full text could not be accessed were excluded. The remaining publications were checked and evaluated to determine whether they contain supportive materials for PAI in dentistry. Results The majority of articles about PAI in dentistry are associated with caries studies. Photoacoustic microscopy is the most commonly utilized PAI system. PAI studies generally focus on ex-vivo investigations using extracted human teeth. The acoustic signal obtained from carious teeth is greater than that obtained from normal teeth. In addition to imaging oral soft tissues from animal models and the periodontal pocket depth in human volunteers, PAI is applied to evaluate dental implants and oral biofilms. Conclusion There have been numerous investigation on PAI in dentistry, but it is not yet applicable in dental practice. In the future, PAI studies are expected to contribute to the invention of an alternative non-ionizing imaging technology that is comfortable for patients, user friendly, and capable of providing reliable information at a reasonable cost.

Abstract
BACKGROUND Oral health is of fundamental importance to maintain systemic health in humans. Stem cell-based oral tissue regeneration is a promising strategy to achieve the recovery of impaired oral tissue. As a highly conserved process of lysosomal degradation, autophagy induction regulates stem cell function physiologically and pathologically. Autophagy activation can serve as a cytoprotective mechanism in stressful environments, while insufficient or over-activation may also lead to cell function dysregulation and cell death. AIM OF REVIEW This review focuses on the effects of autophagy on stem cell function and oral tissue regeneration, with particular emphasis on diverse roles of autophagy in different oral tissues, including periodontal tissue, bone tissue, dentin pulp tissue, oral mucosa, salivary gland, maxillofacial muscle, temporomandibular joint, etc. Additionally, this review introduces the molecular mechanisms involved in autophagy during the regeneration of different parts of oral tissue, and how autophagy can be regulated by small molecule drugs, biomaterials, exosomes/RNAs or other specific treatments. Finally, this review discusses new perspectives for autophagy manipulation and oral tissue regeneration. KEY SCIENTIFIC CONCEPTS OF REVIEW Overall, this review emphasizes the contribution of autophagy to oral tissue regeneration and highlights the possible approaches for regulating autophagy to promote the regeneration of human oral tissue.

Abstract
Oral health is an essential part of overall health. Matrix metalloproteinase-2 (MMP-2) is a potential biomarker for diseases. The ability to accurately detect MMP-2 in vivo and in vitro is of great importance for the early diagnosis and prognosis, as well as the treatment evaluation, of oral diseases. In this study, cyanine 3 (Cy3) polypeptide containing the specific peptide substrate (PLGVR) of MMP-2 was modified onto SiO2-coated upconversion nanoparticles to fabricate a fluorescence resonance energy transfer (FRET)-based ratiometric fluorescent nanoplatform (UCNPs@SiO2@Cy3-pep). The green upconversion luminescence of UCNPs@SiO2 is quenched by Cy3, while its red upconversion luminescence is undisturbed. After Cy3 is cleaved at the PLGVR peptide by MMP-2, it is detached from the surface of UCNPs@SiO2, resulting in the recovery of green luminescence. Based on this principle, we applied UCNPs@SiO2@Cy3-pep to detect MMP-2 activity in different oral disease samples and models. We found that the level of MMP-2 in saliva of patients with oral cancer was 10 times higher than that of healthy individuals. In addition, the MMP-2 level in patients with periodontitis and severe dental caries also increased to varying degrees compared with that in healthy patients. Finally, in vitro and in vivo imaging experiments revealed that the nanoplatform was effective in monitoring MMP-2 level. Together, the developed nanoplatform can be an ideal tool for medical diagnosis of MMP-2-related diseases.

Abstract
Since dental pulp stem cells (DPSCs) were first reported, six types of dental SCs (DSCs) have been isolated and identified. DSCs originating from the craniofacial neural crest exhibit dental-like tissue differentiation potential and neuro-ectodermal features. As a member of DSCs, dental follicle SCs (DFSCs) are the only cell type obtained at the early developing stage of the tooth prior to eruption. Dental follicle tissue has the distinct advantage of large tissue volume compared with other dental tissues, which is a prerequisite for obtaining a sufficient number of cells to meet the needs of clinical applications. Furthermore, DFSCs exhibit a significantly higher cell proliferation rate, higher colony-formation capacity, and more primitive and better anti-inflammatory effects than other DSCs. In this respect, DFSCs have the potential to be of great clinical significance and translational value in oral and neurological diseases, with natural advantages based on their origin. Lastly, cryopreservation preserves the biological properties of DFSCs and enables them to be used as off-shelf products for clinical applications. This review summarizes and comments on the properties, application potential, and clinical transformation value of DFSCs, thereby inspiring novel perspectives in the future treatment of oral and neurological diseases.

Abstract
PURPOSE Periodontal diseases and caries are common oral diseases that predispose to tooth loss if untreated. In this study, we investigated whether loss of teeth or caries associate with intracranial aneurysm (IA) pathology similar to periodontal diseases. METHODS A total of 166 patients with either IA or aneurysmal subarachnoid hemorrhage (aSAH) underwent oral examination in Kuopio University Hospital and Tampere University Hospital. Findings were compared to geographically matched controls acquired from cross-sectional Health2000 survey. This study consisted of three sequential steps. First, we compared the number of missing teeth and prevalence of caries in IA and aSAH patients and geographically matched control population, second step was a multivariate analysis including other risk factors, and third step was a 13-year follow-up of the Health2000 survey participants with missing teeth or caries at baseline. RESULTS Loss of teeth did not significantly differ between IA patients and controls. In logistic regression model adjusted for known risk factors and demographic data, 1-4 caries lesions (OR: 0.40 95%Cl 0.2-0.9, p = 0.031) was associated with lack of IAs, while age (OR: 1.03 95%Cl 1.01.1 p = 0.024), current smoking (OR: 2.7 95%Cl 1.4-5.1, p = 0.003), and severe periodontitis (OR: 5.99 95%Cl 2.6-13.8, p < 0.001) associated to IA formation. In the cox-regression, severe periodontitis at baseline increased the risk of aSAH (HR: 14.3, 95%Cl 1.5-135.9, p = 0.020) during a 13-year follow-up, while caries or missing teeth did not. CONCLUSION Unlike severe periodontitis, caries does not increase the risk of IAs and aSAHs. However, cariogenic bacteria may participate to IA pathology by disseminating to circulation via inflamed gingival tissue.

Abstract
Background Caries and periodontitis are amongst the most prevalent diseases worldwide, leading to pain and loss of oral function for those affected. Prevention relies heavily on mechanical removal of dental plaque biofilms but for populations where this is not achievable, alternative plaque control methods are required. With concerns over undesirable side-effects and potential bacterial resistance due to the use of chlorhexidine gluconate (CHX), new antimicrobial substances for oral use are greatly needed. Here we have investigated the antimicrobial effect of hypochlorous acid (HOCl), stabilized with acetic acid (HAc), on oral biofilms and compared it to that of CHX. Possible adverse effects of stabilized HOCl on hydroxyapatite surfaces were also examined. Methods Single- and mixed-species biofilms of six common oral bacteria (Streptococcus mutans, Streptococcus gordonii, Actinomyces odontolyticus, Veillonella parvula, Parvimonas micra and Porphyromonas gingivalis) within a flow-cell model were exposed to HOCl stabilized with 0.14% or 2% HAc, pH 4.6, as well as HOCl or HAc alone. Biofilm viability was assessed in situ using confocal laser scanning microscopy following LIVE/DEAD® BacLight™ staining. In-situ quartz crystal microbalance with dissipation (QCM-D) was used to study erosion of hydroxyapatite (HA) surfaces by stabilized HOCl.
Results Low concentrations of HOCl (5 ppm), stabilized with 0.14% or 2% HAc, significantly reduced viability in multi-species biofilms representing supra- and sub-gingival oral communities, after 5 min, without causing erosion of HA surfaces. No equivalent antimicrobial effect was seen for CHX. Gram-positive and Gram-negative bacteria showed no significant differential suceptibility to stabilized HOCl. Conclusions At low concentrations and with exposure times which could be achieved through oral rinsing, HOCl stabilized with HAc had a robust antimicrobial activity on oral biofilms, without causing erosion of HA surfaces or affecting viability of oral keratinocytes. This substance thus appears to offer potential for prevention and/or treatment of oral biofilm-mediated diseases.

Abstract
Oral lichen planus (OLP) is a T-cell-mediated inflammatory disease of the oral mucosa that has been extensively researched over many years but as yet the mechanisms of pathogenesis are still not fully understood. Whilst the specific etiologic factors driving OLP remain ambiguous, evidence points to the development of a chronic, dysregulated immune response to OLP-mediating antigens presented by innate immune cells and oral keratinocytes leading to increased cytokine, chemokine and adhesion molecule expression. These molecules recruit T-cells and mast cells to the diseased site and orchestrate a complex interplay between cells that culminates in keratinocyte cell death, mucosal basement membrane destruction and long-term chronicity of the disease. The main lymphocytes involved are thought to be CD8+ cytotoxic and CD4+ Th1 polarised T-cells although recent evidence indicates the involvement of other Th subsets such as Th9, Th17 and Tregs, suggesting that a more complex immune cell relationship exists during the disease process. This review provides an overview of the immune mechanisms at play in OLP pathogenesis with particular emphasis on the role of the different Th subsets and how these recent discoveries may guide research toward identifying potential therapeutic targets.

Abstract
OBJECTIVE To study the relationship between oral disease and depressive symptoms in middle-aged and older adult populations in China. METHODS The data from the China Health and Retirement Longitudinal Study (CHARLS) done between 2013 and 2015 were analyzed. A total of 3828 middle-aged and older adults showing no depressive symptoms in an assessment with the 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) were selected as the subjects of observation, and oral disease was taken as the dependent variable. Changes in depressive symptoms in the population were tracked in 2015, and the Cox proportional hazards model was used to estimate the relationship between oral diseases and depressive symptoms. RESULTS The detection rate of depressive symptoms was 29.3% in middle-aged and older adults with oral diseases, and that of middle-aged and older adults without oral diseases was 20.4%, the difference being statistically significant ( P<0.001). After controlling for confounding factors, Cox proportional hazards model analysis found an association between oral diseases and depressive symptoms (hazard ratio [ HR]=0.683, 95% confidence interval [ CI]: 0.583-0.800). It was more likely for middle-aged and older women ( HR=0.708, 95% CI: 0.573-0.874) with oral diseases to develop depressive symptoms than men ( HR=0.644, 95% CI: 0.506-0.819) did ( P<0.05). CONCLUSION Oral diseases in the middle-aged and older adult populations tended to lead to depressive symptoms, and women showed higher rate than men did. Prevention and control measures should be taken actively in the course of oral disease treatment to promote mental health of middle-aged and older adults.

Abstract
The link between smoking and the expression of SARS-CoV-2 key entry genes is discussed. Smoking-related cardiac and respiratory diseases are risk factors for COVID-19. The impact of smoking on ACE-2 and TMPRSS2 receptors expression is controversial.
Susceptibility to severe illness from COVID-19 is anticipated to be associated with cigarette smoking as it aggravates the risk of cardiovascular and respiratory illness, including infections. This is particularly important with the advent of a new strain of coronaviruses, the severe acute respiratory syndrome coronavirus (SARS-CoV-2) that has led to the present pandemic, coronavirus disease 2019 (COVID-19). Although, the effects of smoking on COVID-19 are less described and controversial, we presume a link between smoking and COVID-19. Smoking has been shown to enhance the expression of the angiotensin-converting enzyme-2 (ACE-2) and transmembrane serine protease 2 (TMPRSS2) key entry genes utilized by SARS-CoV-2 to infect cells and induce a ‘cytokine storm’, which further increases the severity of COVID-19 clinical course. Nevertheless, the impact of smoking on ACE-2 and TMPRSS2 receptors expression remains paradoxical. Thus, further research is necessary to unravel the association between smoking and COVID-19 and to pursue the development of potential novel therapies that are able to constrain the morbidity and mortality provoked by this infectious disease. Herein we present a brief overview of the current knowledge on the correlation between smoking and the expression of SARS-CoV-2 key entry genes, clinical manifestations, and disease progression.

Abstract
OBJECTIVES Dental patient-reported outcome measures (dPROMs) can be differentiated into outcome measures for all oral diseases, so-called disease-generic dPROMs, and measures for specific oral diseases, so-called disease-specific dPROMs. The aim of this systematic review was to identify the psychometrically validated nonmalignant disease-specific dPROMs for adult patients and the dental patient-reported outcomes (dPROs) they measure. METHODS This systematic review searched Ovid MEDLINE, Embase, PsycINFO, and the Cochrane databases along with hand searching, through July 28, 2020, to identify original articles of English language, multi-item dPROMs for adult dental patients with a specific oral disease, condition, or oral manifestations of systemic diseases. We analyzed the questionnaires for content commonalities, the reference or recall period, and the dimensionality. RESULTS We retrieved 4228 unique references and identified 34 questionnaires; of which, 31 questionnaires captured impacts from oral diseases or conditions and three from oral manifestations of systemic diseases. All questionnaires together contained 102 dPROMs, measuring 75 dPROs. Oral health-related quality of life was a broader dPRO, which was measured by 24 dPROMs. The 74 narrower dPROs were measured by 78 dPROMs. The dPRO names suggested that essentially four dPROs were measured: Oral Function (N = 19), Orofacial Pain (N = 7), Orofacial Appearance (N = 11), and Psychosocial Impact (N = 37). CONCLUSIONS Many psychometrically validated tools (N = 102) are available to measure the impact of specific nonmalignant oral disease on patients. While these tools intend to measure the particular patient-perceived impact profile of the oral disease, all tools measure in essence only four, more general concepts - the dimensions of oral health-related quality of life.

Abstract
The pandemic of COVID-19 in early 2020 is a big challenge to the mechanism of major epidemic prevention and control, the national public health management system, as well as medical and health resources in China. Going through the COVID-19 crisis, we should fully understand the problems and vulnerabilities of the current public health system in China, and it is imperative to deepen and strengthen the public health system which should be throughout whole life cycle and whole process. Oral cavity is the first portal of human body, while illness finds its way in by the mouth. Oral health is highly related to general health and quality of life. The outbreak has drawn the public's attention to the public health system. The establishment and improvement of the oral public health system with the concept of "public health with Chinese characteristics" should also attract people's attentions and thoughts. Furthermore it is urgent to recognize the importance of oral public health.

Abstract
The heavy burden of oral diseases such as oral cancers, dental caries, periodontitis, etc. and their consequence on the patient's quality of life demonstrated an urgent demand for developing effective therapeutics. Quercetin as a natural derived flavonoid, could be utilized in the therapeutic formulation of various diseases such as diabetes, breast cancer and asthma, owing to its prominent pharmacological values. In the last decade, the applications of quercetin as a natural compound in oral treatment have attracted increasing interest due to its multifunction including antioxidant, antibacterial, anti-inflammatory and antineoplastic activities. Besides, considering the low bioavailability of quercetin, great efforts have been made in its drug delivery systems to address the problem of limited application. Therefore, this review summarized the cutting-edge researches on versatile effects and enhanced bioavailability of quercetin resulting from innovative drug delivery systems, particularly focused on its potential against oral diseases. The application of quercetin would provide novel and promising therapeutic approach for clinical treatment, promoting the development of global dental public health.

Abstract
Allergic reactions sometimes participate in the development of perioral and oral diseases, indicating the need for appropriate allergen assessment. This review discusses current knowledge on the potential allergic reactions to different dental materials in patients with oral and perioral diseases. Aside from allergies to various dental materials, similar non-allergic, non-immune contact reactions (irritant or toxic) can occur. Among dental materials, the most frequent allergens are alloys, followed by rubber materials, polymers and acrylates. Allergic reactions to dental alloys that contain nickel, cobalt and amalgam are especially frequent since dentists use them for prosthetic and other restorations. There is a broad spectrum of clinical presentations of oral and perioral diseases possibly related to allergies, such as lichenoid reactions, cheilitis, perioral dermatitis, burning sensations, etc. Despite some limitations, patch test is crucial in the diagnosis and recognition of causative allergens because it reveals contact allergies, and is still superior in differentiating allergic and irritant contact reactions. It is important to examine patient medical histories (e.g., occurrence of symptoms after dental therapy or food consumption), and in consultation with their dentist, carry out allergy tests to specific dental allergens which are used or planned to be used in subsequent treatment.

Abstract
Exosomes are cell-derived membranous vesicles of endosomal origin secreted by all type of cells and present in various body fluids. Exosomes are enriched in peptides, lipids, and nucleic acids, emerging as vital modulators in intercellular communication. Exosomes are increasingly being evaluated as biomarkers for diagnosis and prognosis of diseases, because the constituents of exosomes could be reprogrammed depending on the states of diseases. These features also make exosomes a research hotspot in oral diseases in recent years. In this review, we outlined the characteristics of exosomes, focused on the differential expressions and altered biological functions of exosomes in oral diseases, including oral squamous cell carcinoma, oral leukoplakia, periodontitis, primary Sjögren’s syndrome, oral lichen planus, as well as hand foot and mouth disease. Besides, accumulated evidence documents that it is implementable to consider the natural nanostructured exosomes as a new strategy for disease treatment. Herein, we highlighted the therapeutic potential of exosomes in oral tissue regeneration, oncotherapy, wound healing, and their superiority as therapeutic drug delivery vehicles.

Abstract
Background Matrix metalloproteinases (MMPs) play an important role in tooth formation and the mineralization of dental tissue. The aim of the study was to analyse Czech children with primary/permanent dentition polymorphisms in those genes encoding MMP2, MMP3, MMP9, MMP13, MMP16, and MMP20, which had been previously associated with dental caries in other populations. Methods In total, 782 Czech children were included in this case-control study. DNA samples were taken from 474 subjects with dental caries (with decayed/missing/filled teeth, DMFT ≥ 1) and 155 caries free children (DMFT = 0) aged 13–15 years, as well as 101 preschool children with early childhood caries (ECC, dmft ≥ 1) and 52 caries free children (dmft = 0), were analyzed for nine MMPs single nucleotide polymorphisms (SNPs) using real time polymerase chain reaction TaqMan assays. Results There were no significant differences in the allele and/or genotype frequencies of all the studied MMPs SNPs among children with dental caries in primary/permanent dentition and the healthy controls (P > 0.05). In addition, similar allele or genotype frequencies of the studied MMPs SNPs were found in children with severe dental caries in their permanent teeth (children with DMFT ≥ 6) and the healthy controls (DMFT = 0, P > 0.05). Conclusions This study demonstrated the lack of association between the selected SNPs in candidate genes of MMPs and the susceptibility to or severity of dental caries in both primary and permanent dentitions in Czech children.

Abstract
Background Oral health problems may have numerous effects on general health, including physical fitness and performance. In this review, we aimed to systematically review the available evidence to assess the effect of oral health on general physical fitness. Methods We systematically performed a literature search in two different databases (PUBMED and EMBASE) without restriction to the year of publication. Articles were included if the subjects were humans and the primary aim was to assess the effects of dental and/or oral health problems on physical activity using either objective physical measurements or physical performance tests. The quality of the studies was then assessed using a Joanna Briggs Institute (JBI) Critical Appraisal tool. Results A total of 2651 articles were initially retrieved from the systematic search of the literature. Of these, a final total of 11 articles following the inclusion criteria were included in the review. All of the 11 articles included in the review had good methodological quality. Of the 11 articles, ten articles suggested a correlation between dental and oral condition toward physical fitness, body balance, cardiorespiratory function, and also cognitive function. Only one article found contradictory results, which showed that periodontal conditions did not correlate with the cardiorespiratory function. Malocclusion, including the number of remaining teeth, was reported in five studies (45.4%), periodontal disease was evaluated in six studies (54.5%), along with slight evaluation of periapical inflammation. Conclusion This review suggests that there is a negative effect of poor dental and/or oral health on physical fitness and performance.

Abstract
BACKGROUND Impaired oral health affects oral health-related quality of life (OHrQoL) in orthogeriatric hospitalized patients, and both might be associated with potential risk factors for functional impairment, based on the comprehensive geriatric assessment (CGA) and related blood laboratory values. As data on this field are scarce, we investigated possible associations between oral health, items of the geriatric oral health assessment instrument (GOHAI), CGA assessment tools, and relevant laboratory values. METHODS Explorative cross-sectional pilot study investigating oral and general health, OHrQoL, and functionality based on objective oral health, GOHAI, CGA, and routinely assessed laboratory parameters of orthogeriatric patients. Correlations (Spearman's rho and Pearson's) and regression analysis were performed for the dependent variables functionality, cognition, Mini-Nutritional Assessment, Falls Efficacy Scale (FES), and the 15-item geriatric depression scale (GDS). RESULTS Among all participants (N = 40), several GOHAI single items (GOHAI 1,4,5,7,10,11) correlated with certain CGA assessment results (fear of falling, Barthel index, handgrip power). Reduced subjective oral health (GOHAI, xerostomia) and objective oral health (oral hygiene index, root caries index, unstimulated salivation rate) correlated with reduced general health and CGA results (polypharmacy, handgrip power, FES, GDS). Anemia was seen in all participants, but no associations between reduced oral health and laboratory blood values were detected. CONCLUSION Our results demonstrate the association between impaired subjective and objective oral health, OHrQoL, and physical functional impairment among orthogeriatric patients. Impaired GOHAI item results at the dentist, and the association between GOHAI values and CGA results that implies an association between physical and oral health, should encourage a geriatric check based on CGA, and vice versa. Results encourage interdisciplinary cooperation between geriatricians and dentists, but also indicate the need for further research in this field. TRIAL REGISTRATION DRKS00013230.

Abstract
PURPOSE The aim of this study was to check the pro-apoptotic mechanism of prosthetic reconstruction on epithelial cells of the oral mucosa. PATIENTS AND METHODS The research was carried out on the saliva of healthy patients using prostheses. The sample swabs were stained using the May-Grünwald-Giemsa method and processed by immunohistochemistry for nuclear factor kappa B (NF-κB; p65) and caspase-3. Western blots were used to detect caspase-3, NF-κB, p53 and COX-2 expression. RESULTS We found an increased expression of caspase-3, NF-κB and p53 in the oral epithelial cells of patients using prosthetic restorations compared to the subjects from the control group. No differences in COX-2 expression were found between the groups. The strongest immunoreactivity and expression of caspase-3, NF-κB and p53 were observed in patients using full prosthesis for less than two years. CONCLUSIONS The results of the conducted research indicate that prosthetic restorations may affect the process of apoptosis of oral mucosa epithelial cells. Lack of difference in expression of COX-2 in the saliva of the studied patients suggests that apoptosis is not caused by inflammatory factors.

Abstract
Oral health practitioners routinely perform oral health assessments for the dental patient to determine if oral disease is present. Systemic health is often a contributor to oral health concerns. One area in particular that has a direct effect on oral structures and oral health is poor sleep quality and open mouth breathing. Sleep is a fundamental process of the human body, which regulates core biological functions. Sleep quality reflects a person's ability to fall asleep, stay asleep, and enter into the various rejuvenating sleep cycles for the full duration. A person who does not obtain quality sleep can exhibit a wide range of oral, systemic, and cognitive health problems. Obstructive sleep apnea, which historically has been considered an adult male disease, is being recognized more often in women children. Research suggests various oral malformations found in newborns and young children can manifest as obstructive sleep apnea in adults. Oral health professionals are in a position to recognize the relationship between sleep and health, identify sleep quality concerns in relation to oral health assessments, administer sleep quality assessments, and determine appropriate referrals for further sleep quality evaluation.

Abstract
OBJECTIVE In the era of personalized medicine, it is imperative that oral health is integrated into this concept. The oral cavity fosters a highly individualized microbiome that has evolved to promote oral health, and which exists in a dynamic balance with the host. Microecological changes to the biology of the mouth [e.g. in the host diet and lifestyle, or status of the immune system] may drive deleterious shifts in the composition or metabolic activity of the oral microbiome ['dysbiosis']. This review aims to explore how knowledge of the oral microbiome may be utilized for personalized dentistry at the point-of-care. DESIGN This is a comprehensive narrative review of the literature, summarizing the perspectives of the authors. RESULTS The huge increase in recent knowledge on the ecology and microbiology of the oral cavity generated by 'OMIC' technologies may indeed be clinically translated to support patient care, in terms of prevention, monitoring, risk classification or early diagnosis. The identified clinical applications may not only include dental caries and periodontal disease, but also dental implants and orthodontics. Population-based applications may include systemic health, pregnancy and elderly populations. CONCLUSIONS Applications of selected oral microbiome and host-related biochemical parameters [e.g. the saliva proteome] for personalized dentistry can be customized for different clinical applications or individual populations, at point-of-care hubs.

Abstract
Kampo medicine is a medical system that has been systematically organized based on the reactions of the human body. At present, in Western, herbal medicines means the whole herbal product. It is being called Kampo medicine as a medicinal drug in Japan. Since 2012, the “National Health Insurance Drug Price Standards Related to Dental Treatment” published by the Japan Dental Association have included seven Kampo formulations. In 2015, the Japan Dental Association sent a “Kampo Education Plan for Dentistry” to all dental universities in Japan. Furthermore, the Japanese Society of Oral Therapeutics and Pharmacology compiled a summary of “Evidence for Kampo Treatment in the Field of Oral Surgery.” In addition, the phrase “including wakan-yaku” was included in the draft core model curriculum for dental education in 2016. Thus, Kampo medicine is expected to rapidly spread to the field of dental care and dental medical education. Therefore, the training of dentists with knowledge of both Western and Oriental medicine is required for the treatment of oral pain, periodontal disease, stomatitis, xerostomia, and other complaints concerning oral health. It is our hope that this paper provides a footing for dentists who wish to learn about Kampo medicine and incorporate it into clinical practice.

Abstract
Studies have shown a relationship between maternal periodontal diseases (PDs) and premature delivery. PDs are commonly encountered oral diseases which cause progressive damage to the periodontal ligament and alveolar bones, leading to loss of teeth and oral disabilities. PDs also adversely affect general health by worsening of cardiovascular and metabolic diseases. Moreover, maternal PDs are thought to be related to increasing the frequency of preterm-birth with low birth weight (PBLBW) in new-borns. Prematurity and immaturity are the leading causes of prenatal and infant mortality and is a major public health problem around the world. Inflamed periodontal tissues generate significantly high levels of proinflammatory cytokines that may have systemic effects on the host mother and the fetus. In addition, the bacteria that cause PDs produce endotoxins which can harm the fetus. Furthermore, studies have shown that microorganisms causing PDs can get access to the bloodstream, invading uterine tissues, to induce PBLBW. Another likely mechanism that connects PDs with adverse pregnancy outcome is maternal vitamin D status. A role of inadequate vitamin D status in the genesis of PDs has been reported. Administration of vitamin D supplementation during pregnancy could reduce the risk of maternal infections and adverse pregnancy outcomes. As maternal PDs are significant risk factors for adverse pregnancy outcome, preventive antenatal care for pregnant women in collaboration with the obstetric and dental professions are required.

This study focused on the search for new biomarkers based on liquid chromatography-multiple reaction monitoring (LC-MRM) proteomics profiling of whole saliva from patients with periodontitis compared to healthy subjects. The LC-MRM profiling approach is a new and innovative method that has already been validated for the absolute and multiplexed quantification of biomarkers in several diseases. The dataset for this study was produced using LC-MRM to monitor protein levels in a multiplex assay, it provides clinical information on salivary biomarkers of periodontitis. The data presented here is an extension of our recently published research article (Mertens et al., 2017) [1].

Abstract
Background The aim of this study is to identify the oral health status and treatment needs of Special Olympics athletes with intellectual disabilities from 181 countries by the assessment of oral health parameters and differences between world regions. Material and methods Data were collected through interview and oral examinations within the Healthy Athletes Screening. These data were analysed with descriptive statistics of oral health parameters of athletes from Africa, Asia Pacific, East Asia, Europe/Eurasia, Latin America, Middle East North Africa (MENA) and North America. Mean differences of untreated visible dental caries, gingival signs and missing teeth were tested between regions by one-way ANOVA test and between age groups (8–11, 12–18, 19–39 and 40+) by chi-square tests for multiple comparisons with Hochberg-adjusted p value. The level of significance for all tests was set at a p value < 0.05. Results A total of 149,272 athletes with intellectual disabilities were screened. More than 80% of the athletes reported that they cleaned their mouths at least once a day. Athletes in Europe/Eurasia, Latin America, and MENA presented higher rates of signs of gingival disease than other regions. The prevalence of untreated dental caries was significantly higher in Latin America and the group of 8–11-year-olds from Latin America, Europe/Eurasia and Asia Pacific. Conclusions The data provided by this study demonstrate that continuous efforts for preventive and restorative oral health care are needed for the oral health of these athletes with ID especially in Latin America, MENA and Europe/Eurasia regions.

Abstract
BACKGROUND Despite the standard approach towards denture-induced hyperplasia being surgery, as elderly population increases the systemic problems are carried along. Thus, surgery might be risky for patients with medical conditions. OBJECTIVE In this report, a patient with severe inflammatory papillary hyperplasia, medical problems and dental fear was treated with a 5-week nonsurgical protocol. METHOD Once in a week, the upper denture was relined with a zinc enolic paste, for four weeks. In the fifth week, the denture was relined with fast set polymethyl methacrylate resin instead of zinc enolic paste so that the material would last longer than only a week until the new pair of dentures was manufactured. RESULTS AND CONCLUSION The generated pressure combined with antioxidant and anti-inflammatory properties of the paste led to the elimination of the inflammatory papillary hyperplasia completely, satisfying the patient and allowing the manufacturing of a new set of complete dentures.

Abstract
Background Premastication, the transfer of pre-chewed food, is a common infant and young child feeding practice among the Tsimane, forager-horticulturalists living in the Bolivian Amazon. Research conducted primarily with Western populations has shown that infants harbor distinct oral microbiota from their mothers. Premastication, which is less common in these populations, may influence the colonization and maturation of infant oral microbiota, including via transmission of oral pathogens. We collected premasticated food and saliva samples from Tsimane mothers and infants (9–24 months of age) to test for evidence of bacterial transmission in premasticated foods and overlap in maternal and infant salivary microbiota. We extracted bacterial DNA from two premasticated food samples and 12 matched salivary samples from maternal-infant pairs. DNA sequencing was performed with MiSeq (Illumina). We evaluated maternal and infant microbial composition in terms of relative abundance of specific taxa, alpha and beta diversity, and dissimilarity distances. Results The bacteria in saliva and premasticated food were mapped to 19 phyla and 400 genera and were dominated by Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes. The oral microbial communities of Tsimane mothers and infants who frequently share premasticated food were well-separated in a non-metric multi-dimensional scaling ordination (NMDS) plot. Infant microbiotas clustered together, with weighted Unifrac distances significantly differing between mothers and infants. Infant saliva contained more Firmicutes (p < 0.01) and fewer Proteobacteria (p < 0.05) than did maternal saliva. Many genera previously associated with dental and periodontal infections, e.g. Neisseria, Gemella, Rothia, Actinomyces, Fusobacterium, and Leptotrichia, were more abundant in mothers than in infants. Conclusions Salivary microbiota of Tsimane infants and young children up to two years of age do not appear closely related to those of their mothers, despite frequent premastication and preliminary evidence that maternal bacteria is transmitted to premasticated foods. Infant physiology and diet may constrain colonization by maternal bacteria, including several oral pathogens.

Abstract
Exotic companion carnivores such as ferrets, skunks, fennec foxes, coatimundis, raccoons, and kinkajous presented in clinical practice share similar dental anatomy, function, and diseases. The domestic ferret serves as the representative species for this group with its anatomy, diseases, and conditions described in detail. Dog and cat guidelines for veterinary and home care seem to be relevant and applicable, including dental endodontic procedures. Annual or biannual dental examinations and prophylaxis are recommended. The most common dental and oral problems are tooth wear, plaque and calculus, teeth fractures, gingivitis and periodontitis, tooth loss, abscesses, oral ulceration, tonsillitis, and neoplasia.

Abstract
OBJECTIVES Secretory leukocyte protease inhibitor (SLPI) is an innate-immunity protein displaying antimicrobial and anti-inflammatory properties that is found in high concentrations in saliva. The role of extracellular salivary SLPI in head and neck squamous cell carcinoma (HNSCC) remains unclear. Thus, we aimed to evaluate the association between SLPI and HNSCC risk in the Cancer Prevention Study II Nutrition Cohort. MATERIALS AND METHODS Among 53,180 men and women with no history of cancer who provided an oral rinse between 2001 and 2002, 60 were subsequently diagnosed with incident HNSCC between specimen collection and June 2009. In this nested case-control study, archived oral supernatants were evaluated using the Human SLPI Quantikine ELISA Kit for all 60 cases and 180 controls individually matched on gender, race, date of birth, and date of oral rinse collection. Conditional logistic regression was used to estimate HNSCC risk. RESULTS Overall, pre-diagnostic salivary SLPI was associated with a non-statistically significant higher risk of HNSCC (OR=1.6, 95% CI=0.9-3.0). Among never smokers, high SLPI was associated with a non-statistically significant lower risk (OR=0.5, 95% CI=0.1-1.9), whereas among ever smokers, high SLPI was associated with a statistically significant higher risk (OR=2.1, 95% CI=1.0-4.3) of HNSCC, compared to low SLPI. CONCLUSION While results from this study suggest that higher concentrations of salivary SLPI might increase the risk of HNSCC among ever smokers, more research is needed to verify these findings and define the mechanisms by which SLPI and smoking influence the etiology of HNSCC.

Abstract
Background The oral mucosa is constantly exposed to several irritants and allergens including dental materials, but the role of contact allergy in oral disease is obscure. Objective To analyze positive patch test results in patients with oral diseases and evaluate the clinical relevance of oral diseases with contact allergy to dental materials. Methods We retrospectively analyzed patch test results with dental screening series in 44 patients with oral disease from 2004~2011. Results Oral diseases included oral lichen planus (54.5%), cheilitis (27.3%), burning mouth syndrome (9.1%), and others (9.1%). Thirty-one of 44 patients (70.5%) had positive reactions to one or more allergens. The most commonly detected allergens were gold sodium thiosulfate (25.0%) and nickel sulfate (25.0%), followed by potassium dichromate (22.7%), cobalt (15.9%), palladium (6.8%), mercury (4.5%), copper (4.5%), and methylhydroquinone (4.5%). Six of 24 patients with oral lichen planus had a symptom in areas adjacent to dental materials and positive patch test reactions to allergens contained in the suspected dental materials. Conclusion Patch tests with dental screening series are worth considering for oral diseases, especially for oral lichen planus.

Abstract
White sponge nevus (WSN) is an autosomal dominant hereditary disease. Keratin 4 (KRT4) and Keratin 13 (KRT13) gene mutations were involved in the WSN. We recruited two WSN Chinese families, and oral lesion biopsy with hematoxylin and eosin staining showed that patients had significant pathological characteristics. The mutations of KRT4 and KRT13 gene were detected by PCR and direct sequencing. The multiple alignments of KRT13 from 23 diverse species homology analyses were performed by the ClustalW program. The KRT13 expression was measured by Real-Time RT-PCR and Western blot analysis. Sequencing analysis revealed two mutations of KRT13 gene: one mutation was 332T>C and amino acid change was Leu111Pro. Another mutation was 340C>T and amino acid change was Arg114Cys. The sequence of KRT13 was highly conserved. Real-Time RT-PCR and Western blot analysis results show that KRT13 expression level is lower in patient but keep almost no change in mRNA level. When cells were treated with MG132, KRT13 protein level was increased and kept almost the same in normal and patient cells. We identified two heritable mutations in the KRT13 gene, which were associated with the development of WSN. The abnormal degradation of KRT13 protein of WSN may probably associate with the abnormal ubiquitination process.

Abstract
OBJECTIVES Low level light/laser therapy (LLLT) is the direct application of light to stimulate cell responses (photobiomodulation) in order to promote tissue healing, reduce inflammation and induce analgesia. There have been significant studies demonstrating its application and efficacy at many sites within the body and for treatment of a range of musculoskeletal injuries, degenerative diseases and dysfunction, however, its use on oral tissues has, to date, been limited. The purpose of this review is to consider the potential for LLLT in dental and oral applications by providing background information on its mechanism of action and delivery parameters and by drawing parallels with its treatment use in analogous cells and tissues from other sites of the body. METHODS A literature search on Medline was performed on laser and light treatments in a range of dental/orofacial applications from 2010 to March 2013. The search results were filtered for LLLT relevance. The clinical papers were then arranged to eight broad dental/orofacial categories and reviewed. RESULTS The initial search returned 2778 results, when filtered this was reduced to 153. 41 were review papers or editorials, 65 clinical and 47 laboratory studies. Of all the publications, 130 reported a positive effect in terms of pain relief, fast healing or other improvement in symptoms or appearance and 23 reported inconclusive or negative outcomes. Direct application of light as a therapeutic intervention within the oral cavity (rather than photodynamic therapies, which utilize photosensitizing solutions) has thus far received minimal attention. Data from the limited studies that have been performed which relate to the oral cavity indicate that LLLT may be a reliable, safe and novel approach to treating a range of oral and dental disorders and in particular for those which there is an unmet clinical need. SIGNIFICANCE The potential benefits of LLLT that have been demonstrated in many healthcare fields and include improved healing, reduced inflammation and pain control, which suggest considerable potential for its use in oral tissues.

Abstract
BACKGROUND Secretory leukocyte protease inhibitor (SLPI) is an innate immunity-associated protein known to inhibit HIV transmission, and is thought to inhibit a variety of infectious agents, including human papillomaviruses (HPVs). We aimed to optimize an established ELISA-based SLPI quantification assay for use with oral gargle specimens collected using mouthwash, and to assess preliminary associations with age, smoking status, and alcohol intake. METHODS Oral gargle supernatants from 50 individuals were used to optimize the Human SLPI Quantikine ELISA Kit. Sample suitability was assessed and quality control analyses were conducted. RESULTS Salivary SLPI was successfully recovered from oral gargles with low intra-assay and high inter-individual variability. Initial measurements showed that salivary SLPI varied considerably across individuals, and that SLPI was inversely associated with age. CONCLUSIONS This optimized assay can be used to examine the role of SLPI in the acquisition of oral HPV and other infections.

Abstract
The relationships of Behcet's disease (BD) with oral diseases and the prevalence of an uncommon type of oralStreptococcus sanguis (Str. sanguis) in the oral cavity were investigated in a case-control study. BD patients were compared to patient controls (collagen disease) and healthy controls.An interview questionnaire survey of BD and oral diseases showed that during the pre-onset, onset, and post-onset periods, the incidences of tonsillitis and dental caries, or the history of dental treatment, were greater in BD cases. Typological analysis showed a higher prevalence of an uncommon type ofStr. sanguis, differing from the common type, among BD cases compared to control groups. These results, showing a higher incidence of tonsillitis and dental caries during the presymptomatic period, a greater frequency of dental treatments during the symptomatic period, and the presence of an uncommon type ofStr. sanguis, indicate thatStr. sanguis of an uncommon type is related to increased risk of BD, and the possibility of a causal role is suggested.

Abstract
INTRODUCTION White Sponge Nevus (WSN) is a rare pathology with a pathogenesis on genetic basis, a benign course and a localization affecting the mucosal keratin.WSN is usually a symptomless pathology: when pain is present, some authors reported reduction of symptoms by taking penicillin or oral tetracycline rinses, suggesting that a bacterial overinfection could be at the base of possible painful symptoms. CASE REPORT We describe 2 patients affected by WSN, father and son: they presented two different oral diseases associated with an infection by Staphylococcus aureus. So, we have performed a careful oral hygiene to reduce infection in the oral cavity. In the following days we prescribed 2 rinses a day with a mouthwash containing chlorhexidine digluconate at two different percentages. DISCUSSION Early diagnosis of this lesion is important, because it allows us to exclude other more serious diseases. In the most part of cases, WSN requires no treatment because of its benign and asymptomatic behaviour: up to now, no protocol of treatment for this condition was standardized. Even if WSN is a painless condition, sometime a correlated painful symptomatology was reported. CONCLUSIONS In our experience, we have achieved excellent results even with chlorhexidine digluconate rinses, considering that our treated cases were both infected by Staphylococcus aureus. We hypothesize that the corrugated plaques and the altered texture of the mucosa create the right conditions for the colonization and the development of microbial species such as saprophytic bacteria or fungal species.
