DIAGNOSTIC CRITERIA IN THE PLANNING OF ORTHOPEDIC TREATMENT OF PATIENTS WITH INFLAMMATORY PERIODONTAL DISEASES

Subject. Currently, about 530 types of microorganisms that live in supragingival and subgingival plaque have been discovered. To periodontal pathogens today carry a little more than ten types. The main role in the occurrence of periodontal disease is played by microorganisms included in the “red complex” of BANA+: Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia. With the simultaneous identification of these types can be judged on the high risk of developing periodontal disease. Objective ― calculating the frequency of occurrence of various types of dentition defects of patients with varying severity of periodontal disease, establishing the connection between the severity of periodontal disease and the number of periodontal pathogenic microflora. Methodology. A clinical examination of a patients group which consists of 32 women and 10 men in the age from 38 to 66 years was conducted. Anamnesis was collected using a survey and a special questionnaire. External examination and examination of the oral cavity allowed to find the clinical conditions and anatomical features that leads to periodontal disease’s development. Results. Based on the data of clinical and radiological examination, the patients were divided into three groups according to the severity of periodontal disease. During the clinical examination, we calculated the frequency of occurrence of various types of dentition defects in patients with varying degrees of severity of periodontal disease. Findings. It has been found that the course of chronic generalized periodontitis depends on the number of types of aggressive forms of periodontal pathogens.

Qpcr Quantification

The diagnosis of periodontal disease is mainly based on use of clinical and radiographic evidence. In this study we employed a quantitative PCR analysis of Aggregatibacter actinomycetemcomitans and Treponema denticola as species strongly involved in periodontal diseases, burden in periodontal pockets to detect the main sampling factors that interfere with qPCR results. From 22 patients with advanced periodontal disease, subgingival plaque was comparatively collected by paper points and periodontal Gracey curettes. Samples were collected from the same situs in presence of gingival bleeding and absence of bleeding. The concordance and agreement of results between samples were assessed. The present study demonstrates that subgingival plaque sampling with sterile absorbable paper points is often accompanied by gingival bleeding resulting in quantification biases of periodontal pathogens.

Periodontal Tissues

Periodontal diseases are inflammatory and destructive diseases of the dentogingival complex associated with specific periodontal pathogens inhabiting periodontal pockets. Periodontal diseases lead to damage of the periodontal tissues supporting the teeth (bone and connective tissue) and affect the quality of life of the affected individuals: poor alimentation, tooth loss, social and financial problems. Although it is generally considered that the disease has multifactorial etiology, data show that some specific Gram-negative microorganisms in the subgingival plaque biofilm play a major role in the initiation and progression of periodontitis. Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia form a consortium in the subgingival biofilm and are regarded as the principal periodontopathogenic bacteria. Other microorganisms that have been implicated as predominant species in the disease process are: Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, Peptostreptococcus migros, Eikenella corrodens. In periodontitis, the initiation of the disease is the colonization of the tissues by these pathogenic species. The next step is bacterial invasion or invasion by pathogenic products into the periodontal tissues, interactions of bacteria or their substances with host cells, and this directly/indirectly causes degradation of the periodontium, resulting in tissue destruction.

Rank One

Among dental diseases, periodontal diseases rank one of the leading places and are considered as the most pressing issues of modern dentistry. The presence of concomitant somatic pathology, in particular, cardiovascular, endocrinological, autoimmune diseases is an important factor that considerably determines the course and prognosis of periodontal disease. Metabolic syndrome is regarded as an urgent social and medical issue due to its high prevalence among the general population and its contribution to the development and progression of cardiovascular disease. The number of reports and scientific interest in the metabolic syndrome has grown up significantly in recent years, but despite the significant number of studies, the oral microbiome in patients with periodontal disease and underlying metabolic syndrome is still remaining insufficiently studied. The aim of this work was to investigate the species composition of the microflora in periodontal pockets and the frequency of excretion of certain types of microorganisms in the acute generalized periodontitis in patients with metabolic syndrome. A microbiological study was performed in 30 people with metabolic syndrome and generalized periodontitis, who formed the main group, and in 30 people with generalized periodontitis without endocrinological pathology, who formed a comparison group. The results of microbiological examination indicate pathological changes in the oral microbiome in the patients with metabolic syndrome demonstrating a predominance of periodontal pathogens. It can be assumed that the components of the metabolic syndrome can initiate and support microbial invasion thus resulting in the inflammatory reaction of periodontal tissues. There is a similarity between pathogenetic mechanisms of metabolic syndrome and periodontal disease that lead to the impairment of all types of metabolism: protein, lipid, mineral, carbohydrate. As a consequence, this contributes to the progressive destruction of oral tissues. The obtained data enable to suggest the dependence between the presence of the patient's metabolic syndrome and the development of intensive damage to periodontal tissues.

Introduction: Periodontal Gram-negative bacteria and their products can initiate inflammatory responses in periodontal tissues with systemic consequences. They are associated with the pathogenesis of atherosclerosis and ischemic stroke. Local inflammation and oxidative stress play a crucial role in the pathophysiology of intracranial aneurysms (IAs). Under the hypothesis that the severity of periodontal disease is associated with the formation and rupture of IAs we assessed which periodontal pathogens contribute to the pathogenesis of IAs. Methods: We enrolled patients with ruptured- (n=5, age 60±11.9) and unruptured IAs (n=13, age 67±6.1) and controls without IAs (n=7, age 58±8.5); their prior informed consent was obtained. The severity of periodontitis was recorded using the community periodontal index (CPI) of the Treatment Needs code. Subgingival plaques (n=23) were evaluated with the quantitative real-time PCR assay to check for the Gram-negative bacteria Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum, Treponema denticola, Prevotella intermedia (Pi), Tannerella forsythia, and Porphyromonas gingivalis (Pg). Plasma IgG titers of antibody against Pg, Pi, Aa, and Eikenella corrodens were evaluated by ELISA. Results: The CPI was significantly higher in patients with IAs than the controls (2.7 vs 1.9, p<0.05) and their DNA level of subgingival plaques and their plasma IgG titers of Pg were also higher. Periodontal disease was more severe and the plasma IgG titers of Pg were higher in patients with ruptured- than unruptured IAs, suggesting that Pg is associated not only with the formation but also the rupture of IAs. Conclusions: We present evidence that severe periodontal disease and Pg infection may be involved in the pathophysiology of IAs. The management of periodontal diseases may help to prevent the formation and rupture of IAs.

Novel Strategy

Photodynamic therapy (PDT) based periodontal disease treatment has received extensive attention. However, the deep tissue location of periodontal plaque makes the conventional PDT encounter a bottleneck. Herein, upconversion fluorescent nanomaterial with near-infrared light excitation was introduced into the treatment of periodontal disease, overcoming the limited tissue penetration depth of visible light in PDT. Photosensitizer Ce6 molecules were combined with upconversion nanoparticles (UCNPs) NaYF4:Yb,Er with a novel strategy. The hydrophobic UCNPs were modified with amphiphilic silane, utilizing the hydrophobic chain of the silane to bind to the hydrophobic groups of the UCNPs through a hydrophobic-hydrophobic interaction, and the Ce6 molecules were loaded in this hydrophobic layer. This achieves both the conversion of the hydrophobic to the hydrophilic surface and the loading of the oily photosensitizer molecules. Because the excitation position of the Ce6 molecule is in the red region, Mn ions were doped to enhance red light, and thus the improved PDT function. This Ce6 loaded UCNPs composites with efficient red upconversion luminescence show remarkable bacteriological therapeutic effect on Porphyromonas gingivalis, Prevotella intermedia and Fusobacterium nucleatum and the corresponding biofilms under 980 nm irradiation, indicating a high application prospect in the treatment of periodontal diseases.

Periodontal Destruction

ABSTRACT Aim Periodontal diseases are associated with microorganisms rich in Gram-negative species. Several studies have indicated the presence of few a periodontopathic microorganisms in the same family. A parent with severe adult periodontitis, who is infected with bacteria associated with periodontal disease, may function as a source of infection. Their children may be at a greater risk to become colonized with bacteria. The purpose of this investigation was (1) to explore the presence of three bacteria, such as Porphyromonas gingivalis (PG), Prevotella intermedia (PI), and Aggregatibacter actinomycetemcomitans (AA) in the same Lebanese family and (2) to study the clinical destruction in the same family and their relations as members of this family due to the presence of PG. Materials and methods A total of 10 families were screened; only 5 (13 females and 5 males) were selected for this study, and at least one member of the family had untreated periodontal disease, chronic or aggressive. Every participant signed an informed consent form. A total of 18 available deoxyribonucleic acid (DNA) samples were taken to analyze the presence of three periodontal bacteria. Statistics Multiple logistic regression was used for the exact methods. Results All 18 patients showed a positive result for PI. Also, PG. was recognized in 15 patients while AA was not detected in any of the subjects. All couples suffered from periodontitis, chronic or aggressive forms, five children suffered from gingivitis, three children had no clinical manifestation, and only one suffered from localized aggressive periodontitis. The statistical analysis showed with each 1 year of increase in age, the odds of having periodontal disease multiply by 1.39, i.e., age as a risk factor for periodontal disease due to the presence of PG and sharing the same plate. Conclusion This investigation demonstrates a high prevalence of periodontal microorganisms in children and young adults of Lebanese periodontitis parents and a microbiological similarity between the children and their mothers. All these factors could be a high risk of developing periodontal disease in the future. Clinical significance This article shows that vertical transmission of microorganisms is a possible risk factor for developing periodontal disease in the offspring.

Objective: Treponema denticola “T. denticola” is a pathogen associated with periodontal diseases that exhibits capacity for adherence, invasion, and colonization of host tissues, which allows alternating its location and damage in different sites of human body. This review aimed to discuss different studies that detected T. denticola in atherosclerotic plaques, demonstrating the importance of periodontal disease on the systemic health and the necessity of exploring the outcome of this colonization apart from the oral cavity. Methodology: Fifty-five studies were identified and gathered in this review according to the following topics: Periodontal disease, atherosclerosis and T. denticola. In vitro and in vivo studies published between 2002 and 2020 were searched on PubMed, raising relevant insights about the role of T. denticola and its association with the systemic disease, atherosclerosis, focusing on the bacterial tissue invasion and development of atherosclerosis. Results: After bibliographic review, it was possible to identify studies demonstrating the presence of T. denticola and other oral pathogens in cardiac or vascular tissues and in blood serum, as well, there is research in which other evidence of a relationship with atherosclerosis is shown. Conclusion: The invasion of periodontal pathogens and its toxins associated to the host’s immune and inflammatory response may contribute to the development of atherosclerosis.

The article presents a review and analysis of relevant available literature sources on etiopathogenetic mechanisms of periodontal disease and liver diseases of viral aetiology, and, in particular, hepatitis B and C viruses. Significant prevalence, pronounced polymorphism of clinical hepatic and extrahepatic manifestations, the incidence rate of liver cirrhosis and hepatocellular carcinoma allows us to consider hepatitis of viral aetiology as a medical and social challenge. Multi-vector liver dysfunctions can cause oral presentations in this group of patients, and in particular, in their periodontal tissues. Viral liver damage is associated with significant impairment of the microbiocenosis in gingival sulcus and periodontal pockets. Dysbiotic changes are characterized by an increase in the number of opportunistic pathogens and anaerobic periodontal pathogens. Exacerbation of dysbiosis along with deterioration of oral hygiene occurs as a consequence of reduced local resistance and hyposalivation due to the sialotropic properties of hepatitis C virus. Significant pathogenetic role in the development of periodontal disease is played by disorders of metabolic and synthetic functions of the liver, as well as hormonal imbalance, metabolic disorders, immune-mediated damage, induction of autoimmune mechanisms and cytokine imbalance. The formation of hepatogenic osteopenia and osteoporosis enhances the loss of bone mass of the alveolar processes in the jaws and, accordingly, the resorption of bone tissue with the further progression of more aggressive forms of generalized periodontitis.

Immune System Dysfunction

Periodontal diseases are immune inflammatory responses induced by dental plaque in which microorganisms harboured within a susceptible periodontium contributes to tissue destruction, bone loss and eventually tooth loss. The etiopathogenesis of periodontal disease is multifactorial which includes host associated factors, genetic factors, immune system dysfunction and environmental factors. Existing treatment modalities have resulted only in arresting the disease progression but have not cured the disease completely, nor do they avert the recurrence. Hence there is a need for therapeutic modalities which may include vaccines targeting periodontal pathogens. Vaccination is induction of immunity by injecting a dead or attenuated form of pathogen. Till date, no pre-emptive modality exists for periodontal disease, the availability of periodontal vaccine would prevent the progression of periodontal diseases. The aim of this review article is to confer the various approaches associated with periodontal vaccine.

The Past

Relevance. The modern view of periodontitis as a dysbiotic disease that occurs as a result of changes in the microbial composition of the subgingival region is considered in a systematic review.Purpose. To study a new paradigm of development of generalized periodontitis.Materials and methods. Randomized controlled trials (RCTS) were selected for the study, including cluster RCTS, controlled (non-randomized) microbiological and clinical studies of the oral microbiome in adult patients with generalized periodontitis over the past 10 years.Results. The transition from a symbiotic microflora to a dysbiotic pathogenic community triggers the host's inflammatory response, which contributes to the development of periodontal diseases. Modern ideas about periodontal pathogenic bacteria dictate new requirements for the treatment of periodontal diseases. The second part of the review examines the microbial profiles of periodontal disease in various nosological forms, the mechanisms of the immune response and approaches to the treatment of periodontal disease from the perspective of biofilm infection.Conclusions. As follows from modern literature periodontitis is to a certain extent caused by the transition from a harmonious symbiotic bacterial community to a dysbiotic one. Recent scientific studies have shown that not single microorganism is not able to cause disease but the microbial community as a whole leads to the development of pathology.
