Periodontitis is a complex, multifactorial infectious disease, which affects a high proportion of the global population. Recent studies show that periodontal disease has strong negative impact on the homeostasis of the oral cavity but has also been associated with several systemic diseases. Although some correlation mechanisms between periodontitis and certain systemic disease have been described further extensive investigations are needed to establish causality. Periodontitis could be involved in the onset and progression of some types of cancers, especially oral cancer due to chronic inflammation. The release of citokines and inflammatory markers at a local level and in the blood stream can disregulate the variables of the body and can be directly involved in the mechanim of tumorigenesis. Another hypothesis relies on the role of disbiosis of the oral microbiome and the structural and functional alterations of the subgingival flora which define periodontitis in the oral cancer development. The prevalence of oral cancer is very high and continous increase at an alarming rate globally. The rapid progression and aggressive behavior of oral cancer, the high mortality rate, the comorbidities and negative effect on the quality of life after cancer treatment but most importantly the low survival rate on the long term highlight the need to supress all the potential risk factors in order to prevent this disease. Periodontal status evaluation and periodontal therapy should be initiated in patients undergoing cancer therapy in order to lower the risk of complications associated with radiation- and chemotherapy. Also on the long run treatment of periodontal disease could prevent the development of a new oropharyngial carcinoma.

Despite advancement in cancer treatment, oral cancer has a poor prognosis and is often detected at late stage. To overcome these challenges, investigators should search for early diagnostic and prognostic biomarkers. More than 700 bacterial species reside in the oral cavity. The oral microbiome population varies by saliva and different habitats of oral cavity. Tobacco, alcohol, and betel nut, which are causative factors of oral cancer, may alter the oral microbiome composition. Both pathogenic and commensal strains of bacteria have significantly contributed to oral cancer. Numerous bacterial species in the oral cavity are involved in chronic inflammation that lead to development of oral carcinogenesis. Bacterial products and its metabolic by-products may induce permanent genetic alterations in epithelial cells of the host that drive proliferation and/or survival of epithelial cells. Porphyromonas gingivalis and Fusobacterium nucleatum induce production of inflammatory cytokines, cell proliferation, and inhibition of apoptosis, cellular invasion, and migration thorough host cell genomic alterations. Recent advancement in metagenomic technologies may be useful in identifying oral cancer–related microbiome, their genomes, virulence properties, and their interaction with host immunity. It is very important to address which bacterial species is responsible for driving oral carcinogenesis. Alteration in the oral commensal microbial communities have potential application as a diagnostic tool to predict oral squamous cell carcinoma. Clinicians should be aware that the protective properties of the resident microflora are beneficial to define treatment strategies. To develop highly precise and effective therapeutic approaches, identification of specific oral microbiomes may be required. In this review, we narrate the role of microbiome in the progression of oral cancer and its role as an early diagnostic and prognostic biomarker for oral cancer.

Subject. The scientific works of recent years show an increase in the degree of negative impact of vitamin deficiency and vitamin-like substances on the state of health of the population. With the deficiency of most vitamins, synthetic processes and regeneration of oral tissues are reduced, so often the initial signs of hypovitaminosis are stomatitis, gingivitis, glossitis, and therefore, it is dentists who are the first to diagnose deviations in the body associated with vitamin deficiency. This justifies the relevance and practical value of studying and describing clinical cases of manifestations of deficient vitamin conditions in the oral cavity. The object – is to study the effect of B vitamins on the oral mucosa in order to increase the effectiveness of diagnosis of vitamin-deficient conditions of the human body. Methodology. These clinical examples illustrate the management experience of patients with manifestations of deficient vitamin conditions on the oral mucosa. Clinical and laboratory methods of diagnosing the analysed conditions of the organism were applied. Statistical processing of materials was carried out using the STATISTICA 10 software (StatSoft, Inc., USA). Results. The deficient condition of the organism in relation to vitamins B2, B6, B12 in patients 18-75 years old has been studied. Characteristic clinical changes on the oral mucosa of the examined patients were established. So, in most patients with vitamin B2 deficiency, the classic Sebrel triad was found: dermatitis, glossitis, cheilitis. In those examined with a lack of vitamin B6, language desquamations (smoothed, polished language) were determined in the 83.6%, often combined with glossodinia. Patients with vitamin B12 deficiency were characterized by a lesion in the form of Meller-Gunter glossitis in 74.9% of cases, moreover, 67.6% of patients showed paresthesia in the area of tongue and oral mucosa. Conclusions. The study found that the first clinical symptoms of deficient conditions of the presented vitamins of group B were found from the oral cavity. Thus, it is the dentist who is the first to diagnose the pathological states of lack of group B vitamins in the human body, which emphasizes the importance and relevance of continuing to study these states of the body.

Subject. Removable dentures have a negative impact on supporting tissues, biochemical parameters and composition of the microflora of the oral cavity, secretory activity of the salivary glands and other processes of the maxillofacial region and the body as a whole. One of the methods that can be used in the treatment and prevention of prosthetic stomatitis is balneotherapy. In the article, using the clinical, biochemical, microbiological and histological methods, the effectiveness of the use of mineral water "Fateevskaya" in patients using removable orthopedic structures was studied. Objectives of the study was to evaluate the effectiveness of procedures for small balneotherapy with the use of mineral water "Fateevskaya" in patients with removable dentures. Methods.We examined 158 elderly and senile age patients with removable dentures. Correction of removable dentures was carried out to all patients at the initial stage. All examined patients are divided into two groups. The group received the treatment with the low balneotherapy with “Fateevskaya” mineral water (78 patients, and the clinical control group (80 patients). The clinical condition of oral cavity was assessed before and after the course of low balneotherapy. Were researched: changes of mucous membrane of prosthetic bed, salivation rates, disturbance of salivary secretion, oral microbiocenosis. Results.Of the research showed that in both groups were increase of pH value, appears lower values of total protein and glucose, decrease in activity of some enzymes. This explanation is due to a decrease in the stress response to using the removable dentures, normalization of salivary glands functioning, decrease in the intensity of the phlogiston process. The results of a histological research also confirm this. The results of microbiological crops before and after the low balneotherapy indicate the oral biocenosis normalization. The positive changes in the researched parameters had significantly larger statistically valid values in the group received the treatment with the low balneotherapy with “Fateevskaya” mineral water. The results of the complex research allow us to recommend the “Fateevskaya” mineral water to low balneotherapy in dental practice.

This comprehensive review of the literature aimed to investigate the interplay between the oral microbiome, oral cavity conditions, and host immune response in Diabetes mellitus (DM). Moreover, this review also aimed to investigate how DM related risk factors, such as advanced age, hyperglycemia, hyperlipidemia, obesity, hypertension and polycystic ovary syndrome (PCOS), act in promoting or modifying specific mechanisms that could potentially perpetuate both altered systemic and oral conditions. We found that poorly controlled glycemic index may exert a negative effect on the immune system of affected individuals, leading to a deficient immune response or to an exacerbation of the inflammatory response exacerbating DM-related complications. Hyperglycemia induces alterations in the oral microbiome since poor glycemic control is associated with increased levels and frequencies of periodontal pathogens in the subgingival biofilm of individuals with DM. A bidirectional relationship between periodontal diseases and DM has been suggested: DM patients may have an exaggerated inflammatory response, poor repair and bone resorption that aggravates periodontal disease whereas the increased levels of systemic pro-inflammatory mediators found in individuals affected with periodontal disease exacerbates insulin resistance. SARS-CoV-2 infection may represent an aggravating factor for individuals with DM. Individuals with DM tend to have low salivary flow and a high prevalence of xerostomia, but the association between prevalence/experience of dental caries and DM is still unclear. DM has also been associated to the development of lesions in the oral mucosa, especially potentially malignant ones and those associated with fungal infections. Obesity plays an important role in the induction and progression of DM. Co-affected obese and DM individuals tend to present worse oral health conditions. A decrease in HDL and, an increase in triglycerides bloodstream levels seem to be associated with an increase on the load of periodontopathogens on oral cavity. Moreover, DM may increase the likelihood of halitosis. Prevalence of impaired taste perception and impaired smell recognition tend to be greater in DM patients. An important interplay among oral cavity microbiome, DM, obesity and hypertension has been proposed as the reduction of nitrate into nitrite, in addition to contribute to lowering of blood pressure, reduces oxidative stress and increases insulin secretion, being these effects desirable for the control of obesity and DM. Women with PCOS tend to present a distinct oral microbial composition and an elevated systemic response to selective members of this microbial community, but the association between oral microbiome, PCOS are DM is still unknown. The results of the studies presented in this review suggest the interplay among the oral microbiome, oral cavity conditions, host immune response and DM and some of the DM associated risk factors exist. DM individuals need to be encouraged and motivated for an adequate oral health care. In addition, these results show the importance of adopting multidisciplinary management of DM and of strengthening physicians-dentists relationship focusing on both systemic and on oral cavity conditions of DM patients.

Background: The use of tobacco may affect the human oral microbiome resulting in numerous diseases including cancer. There are more than 1.3 billion tobacco smokers worldwide with 4.5 million adult Nigerians addressed as tobacco addicts. Tobacco smoking causes oral cancer, color change on the teeth, halitosis, periodontitis and other health implications. Aim: The study was aimed at determining the changes caused by tobacco smoking on the oral microbiome of cigarette smokers and the shift toward organisms that may cause oral cancer and lung diseases. Methods: One hundred and twenty subjects made of 60 tobacco smokers and 60 nonsmokers were enrolled for the study. Oral swabs were collected from the oral cavity of the subjects using sterile swab sticks under standard aseptic methods. The specimens were subjected to microscopy and culture. Organisms were identified using standard microbiological techniques. Results: The mean age of the subjects was 26.9 ± 3.4 years, with minimum age 18.0 years. There was a higher rate of bacterial colonization 86.7% among smokers than nonsmokers (χ2 = 299.0, P = 0.0002). Most members of the oral biofilm belonged to the Enterobacteriaceae with Klebsiella pneumoniae being the most prevalent isolate among smokers while Pseudomonas aeruginosa 4 (20.0%) were the most prevalent bacterial isolates among the control subjects. Tooth decay 19 (36.5%) was the oral cavity disorder among smokers associated with the highest number of isolates, followed by halitosis 18 (34.6%) and mouth ulcer 7 (13.4%). Halitosis was mostly associated with Candida species 5 (71.4%). There was a statistically significant association between oral cavity conditions and microbial isolates among smokers (χ2 = 299.0, P = 0.002). Conclusion: Smoking may have altered bacterial acquisition and oral mucosal colonization in favor of periodontal pathogens. This study have shown that smoking predisposes to oral cavity diseases which may predispose to oral cancer or lung diseases. The campaign against smoking should therefore be intensified as this may help to improve the oral health of smokers.

ABSTRACT Oral cavity is the window to the body and is often the area where systemic disease first presents itself. The various tissues including lips, tongue, gingiva, mucosal surfaces, dentition, and bone are involved in the presentation of disease state. The most frequently affected is the periodontium, followed by the oral mucous membrane and the periapical inflammations. The review is not all inclusive; however, it does address some of the most common, as well as a few of the more rare anemia-associated disease states observed in both adults and children.

Background: The oral cavity is a mirror of the body, entry point to food, antigens, and microorganisms. Oral cavity with mastication and speech, also have a role play in immunological defense. The Oral mucous membrane is in link with skin, oropharynx, and nasopharynx. The oral cavity and anterior two-thirds of the tongue are formed by the ectoderm and that is why from a dermatologist's viewpoint, an oral opening is especially imperative and involved in a range of systemic and skin disease, also affect teeth and gums. The body's natural protection is in good quality oral care. Oral problems when associated with skin conditions require oral care as it affects the quality of life and enable dermatologist and dentist in the identification and diagnosing of systemic disease. Oral illness can bring into being from infection, inflammation or neoplastic, immunological, benign, or malignant. Results: The oral cavity is a mirror to a variety of systemic and cutaneous diseases. Interpretation of the symptom and signs of systemic diseases help early diagnosis. However, while not correct oral hygiene, microorganisms will reach levels that may result in oral infections and decay. The health status of our oral cavity can give us a strong signal of the health of our bodies. It proceeds as a premature warning system. That's why the oral cavity should be examined in one piece from the buccal mucosa to the oropharynx. Conclusion: The mouth is a straightforwardly available window of the body. In contemplation with development, composition, and utility oral cavity is only one of its kind. It is a two-way road as systemic skin disease has oral manifestation. Interpretation of the symptom and signs help in identification and early diagnosis of systemic diseases. Oral illness can bring into being from infection, inflammation or neoplastic, immunological, benign, or malignant. That's why the oral cavity should be examined in one piece from buccal mucosa, lips, tongue, gum, teeth, palate to the oropharynx. Knowledge of systemic diseases is vital in day to day clinical practice, often oral manifestation is the most significant or first sign of systemic illness. So dermatologists and dental surgeons are conscious of oral complaints and their association with systemic disease.

The oral cavity as the second most various microbial community in the body contains a broad spectrum of microorganisms which are known as the oral microbiome. The oral microbiome includes different types of microbes such as bacteria, fungi, viruses, and protozoa. Numerous factors can affect the equilibrium of the oral microbiome community which can eventually lead to orodental infectious diseases. Periodontitis, dental caries, oral leukoplakia, oral squamous cell carcinoma are some multifactorial infectious diseases in the oral cavity. In defending against infection, the immune system has an essential role. Depending on the speed and specificity of the reaction, immunity is divided into two different types which are named the innate and the adaptive responses but also there is much interaction between them. In these responses, different types of immune cells are present and recent evidence demonstrates that these cell types both within the innate and adaptive immune systems are capable of secreting some extracellular vesicles named exosomes which are involved in the response to infection. Exosomes are 30–150 nm lipid bilayer vesicles that consist of variant molecules, including proteins, lipids, and genetic materials and they have been associated with cell-to-cell communications. However, some kinds of exosomes can be effective on the pathogenicity of various microorganisms and promoting infections, and some other ones have antimicrobial and anti-infective functions in microbial diseases. These discrepancies in performance are due to the origin of the exosome. Exosomes can modulate the innate and specific immune responses of host cells by participating in antigen presentation for activation of immune cells and stimulating the release of inflammatory factors and the expression of immune molecules. Also, mesenchymal stromal/stem cells (MSCs)-derived exosomes participate in immunomodulation by different mechanisms. Ease of expansion and immunotherapeutic capabilities of MSCs, develop their applications in hundreds of clinical trials. Recently, it has been shown that cell-free therapies, like exosome therapies, by having more advantages than previous treatment methods are emerging as a promising strategy for the treatment of several diseases, in particular inflammatory conditions. In orodental infectious disease, exosomes can also play an important role by modulating immunoinflammatory responses. Therefore, MSCs-derived exosomes may have potential therapeutic effects to be a choice for controlling and treatment of orodental infectious diseases.

A healthy mouth is necessary for optimal health and quality of life. However, oral health is often compromised in adults with chronic kidney disease (CKD). The aim of this review was to present the scientific foundations behind the connection between oral diseases and chronic kidney disease (CKD) in adults, discuss common oral conditions and their systemic effects, investigate biological pathways through which oral infections affect the body and provide guidelines for physicians/nephrologists. Prevalence of oral disease is increased in CKD, including periodontal disease, oral mucosal lesions, edentulousness, xerostomia, gingival overgrowth in immunosuppressed patients and potentially caries. There is moderate to strong evidence to support a negative impact of oral infections in CKD, particularly periodontal disease, with systemic inflammation, bacteraemia of oral origin, endothelial function and gut dysbiosis being potential pathways for this interaction. Poor oral health can be a hidden source of infection and has been associated with increased mortality in CKD patients. Elimination of potential foci for oral infections is crucial before renal transplantation. Frequent dental monitoring is crucial for these patients and should be part of a multidisciplinary approach to manage CKD, with special attention to end-stage kidney disease.
