Protective function of oral fluid is evident in maintaining constant saliva volume, moisturizing mucous membranes of the oral cavity, teeth enamel, preventing the defeat of soft and hard tissues of the oral cavity by pathogenic microorganisms. A number of factors, called "barriers of colonization", specifically and nonspecifically manage the process. What matters most is "mucous block”, which characterizes the set of mechanical, humoral, nonspecific factors of protecting mucous membranes against microorganisms. Mucin proteins which are the main glicoproteine saliva components affect the creation and selection of biofilm microflora, facilitating or inhibiting the adhesion of microorganisms and maintaining healthy microbial environment in the oral cavity. The dominant mucin of submucosa glands is MUC5B, which is encoded by the same gene, located in a short shoulder of segment 15.5 of chromosome 11. Changes of the basic physical and chemical properties of nonstimulated saliva in children with Down syndrome, namely, reduction of pH level and increasing oral fluid viscosity, is certainly an important prerequisite for formation of cariogenic situation.Keywords: Down syndrome, MUC5B, oral cavity, saliva.  АНАЛІЗ ПОЛІМОРФІЗМУ VNTR ГЕНУ MUC5B У ЗВ'ЯЗКУ З ДЕЯКИМИ ФІЗІКО-ХІМІЧНИМИ ВЛАСТИВОСТЯМИ РОТОВОЇ РІДИНИ У ДІТЕЙ З СИНДРОМОМ ДАУНА.Назарян Р.С., Іскоростенська О.В., Горенська О.В., Волкова Н.Є. Захисна функція ротової рідини проявляється у підтриманні постійного об'єму слини, зволоженні слизової оболонки ротової порожнини, емалі зубів, запобіганні ураження м'яких і твердих тканин ротової порожнини патогенними мікроорганізмами. Цілий ряд факторів, що їх називають "бар'єрами колонізації", специфічно та неспецифічно керує процесом. Найбільше значення при цьому має "мукозний блок”, який характеризує комплекс механічних, гуморальних, не специфічних факторів захисту слизової оболонки від мікроорганізмів. Білки-муцини, які є основними глікопротеїновими компонентами слини, впливають на створення і вибір мікрофлори біоплівки, полегшуючи або попереджаючи адгезію мікроорганізмів і підтримуючи здорову мікробну середу ротової порожнини. Домінуючим муцином залоз підслизового слою є MUC5B, який кодується однойменним геном, розташованим у короткому плечі сегмента 15.5 хромосоми 11. Зміни основних фізико-хімічних властивостей нестимульованої слини у дітей з діагнозом синдром Дауна, а саме зменшення рівня рН і підвищення рівня плинності ротової рідини, безумовно є важливою передумовою для утворення карієсогенної ситуації.Ключові слова: MUC5B, ротова порожнина, синдром Дауна, слина. АНАЛИЗ ПОЛИМОРФИЗМА VNTR ГЕНА MUC5B В СВЯЗИ С НЕКОТОРЫМИ ФИЗИКО-ХИМИЧЕСКИМИ СВОЙСТВАМИ РОТОВОЙ ЖИДКОСТИ У ДЕТЕЙ С СИНДРОМОМ ДАУНА.Назарян Р.С., Искоростенская О.В., Горенская О.В., Волкова Н.Е.

Introduction: Caries occurs most frequently among dental diseases of the hard dental tissues in children. Its occurrence and intensity do not decrease, although scientists and practitioners make much efforts directed to the reduction of these indices The aim: Therefore, the objective of our study was to investigate the indices of rate salivation and viscosity of the oral fluid in children at different age periods with caries and intact teeth. Materials and methods: 134 children, 7-9 years old, and 89 children,10-12 years old, studying at Poltava schools were examined. Dental examination was conducted according to the common methods. Caries intensity in all the children was determined by Caries Filling Extraction (CFE) Index, and CFE+cfe. To determine salivation rate the oral fluid was collected on empty stomach in the morning into sterile calibrated tubes during 5 minutes. Results and conclusions: Investigations of physical indices of the oral fluid in children of 7-9 and 10-12 years of age did not find their reliable difference considering the child’s age. Meanwhile the indices of salivation rate and oral fluid viscosity in children with caries and without it were found to differ much. That is, the course of carious process in children is associated with reduced salivation rate and increased index of the oral fluid viscosity, which in its turn deteriorates hygienic state of the oral cavity enabling to activate the activity of dental deposit microflora and its effect on enamel demineralization followed by occurrence of carious defect of temporary and especially permanent teeth recently erupted and poorly mineralized. The results obtained were calculated by variation statistics method. The indices were considered to be reliable with р≤0,05.

According to the authors, the prevalence of SOPR diseases is from 3 to 20%.In a study of 1573 residents of southern China in two age groups who use tobacco and alcohol, the incidence of SOPR was higher among men living in rural areas compared to urban residents. Among women aged 35-44 years, the incidence was higher in urban women, and in the 65-77-year-old group in rural women. In the course of studies in Brazil, among 335 patients older than 60 years, 646 diseases of the SOPR were identified. Similar results were obtained in the analysis of SOPR diseases in the Volgograd region of the Russian Federation

Sjögren‘S Syndrome

Dryness of the mucous membranes (in mouth, nose, genitals in women) and skin are the most common complaints of patients with Sjogren’s disease — a multisystem immune‑mediated disorder that causes anxiety and concern associated with the difficulties of initial diagnosis. The authors present a clinical case of a patient with primary Sjogren’s syndrome, a large number of symptoms of digestive diseases, complaints of dryness of mucous membranes, in particular the oral cavity. The diagnosis was confirmed by allied specialists such as ophthalmologist, gynecologist, rheumatologist, dentist. Detailed dental examination revealed the main dental complaints (constant dry mouth, galitos, changes in taste), clinical condition (dryness of the red border of the lips, swelling of the oral mucosa, changes in the relief of the gums), decreased secretory activity and significant reduction of unstimulated salivation with a moderate level of stimulated salivation. It is noted that a significant decrease in sialometry (0.01 ml per minute) and functional activity of the small salivary glands (up to 18) confirms the presence of true xerostomia. Micro‑crystallization of saliva revealed disorganization of irregularly shaped structures, as well as a significant number of organic inclusions, which indicates a violation of homeostasis in the oral cavity. Given the results of ultrasound examination of the large salivary glands and the absence of enlargement and swelling of the glands during clinical examination, we can assume that the destructive damage to the glands is not so pronounced, evacuation function of the gland is not reduced, but the amount of secretion is significantly reduced. To provide medical aid to patients with Sjogren’s syndrome, the accessibility of the qualified consultation is important and required, with conduction of comprehensive examinations by allied specialists, including a dentist.

Pemphigus vulgaris (PV) is a chronic autoimmune mucocutaneous disease. In most cases, the initial manifestation occurs in the mouth as multiple ulcerations preceded by blisters that rupture and later spread to other mucous membranes and the skin. Esophageal impairment is rare. We report a case of PV with esophageal involvement in a 53-year-old woman who sought medical care, complaining of diffuse painful lesions in the oral cavity for approximately 1 month, with no improvement with nystatin. Upper digestive endoscopy (UDE) was performed with findings of vesiculobullous lesions in the proximal and middle esophagus, which were biopsied and for which histopathology confirmed PV in the esophageal mucosa. We draw attention to UDE as important for the diagnosis, and it should be indicated in patients with vesiculobullous lesions of the mouth, especially if there are esophageal complaints.

Introduction. The most popular type of dentures is permanent orthopedic structures. However, their use is a serious intervention that changes biological balance in the oral cavity through galvanic, reflex and toxic allergic effects. Because of this, galvanic currents appear in the oral cavity, which have an adverse effect on the oral mucosa and the physicochemical parameters of the oral fluid. As a result of increasing bioelectric potentials in the oral cavity, oral microbiocenosis disorders may occur, the periodontium pathology develops or worsens and an unpleasant odor arises, which in aggregate can cause a social maladjustment of the patient. It is known that the main intraoral factor in the development of halitosis is the unsatisfactory hygienic condition of the oral cavity. Non-removable dentures made from non-noble dental alloys can also significantly affect the development of intraoral halitosis. Objective. To study potentiometric parameters in patients with intraoral halitosis who have fixed orthopedic constructions made of various materials by various technologies. Methods and Materials. 158 people aged 35-55 years with fixed orthopedic constructions in the oral cavity in the amount of 5-8 units with a service life of 2-3 years were examined. Four groups were formed: with stamped-brazed dentures, with cast-denture prostheses from dental alloys, with cast-in-place titanium structures and a control group without disrupting the integrity of the dentition. All patients underwent a sanation of the oral cavity, professional hygiene and anti-inflammatory treatment. In addition, hygienic training of patients with quality control of personal hygiene was conducted. In the course of the study, 35 patients from the first and second groups after the complex treatment were replaced by replacing the existing dentures with orthopedic structures made of titanium. The effectiveness of treatment was assessed by the dynamics of indices of hygiene, PMA, organoleptic assessment of halitosis and potentiometric parameters. Results. As a result of the study, it was found that patients with dentures, manufactured with the help of the stamped-brazed technology, were characterized by high indices of hygiene (1.29 ± 0.18 points) and PMA (66.79 ± 2.48%). The I degree of halitosis was observed in 27 patients (41.5%) of this group, II degree was observed in 35 people (53.8%) and III degree in 3 people (4.6%). In the second group, the hygiene index was 0.97 ± 0.12, the PMA index was 65.57 ± 2.18%. In 33 patients (67.4%) I degree of halitosis was detected, in 16 patients (32.6%) – II degree. In the third group, the hygiene index was 0.84 ± 0.12, the PMA index was 56.23 ± 1.22. Unpleasant odor in the majority of patients in this group (40 people or 90.9%) was determined when approaching a distance of 10 cm, which corresponded to I degree of halitosis. Only 4 patients (9.1%) had halitosis of II degree. In the control group, the KPI index was 12.13 ± 0.24, the level of hygiene was on average 0.81 ± 0.12 points and 55.56 ± 1.13%, respectively. There were no organoleptic signs of halitosis in this group.

Erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis are related disorders of skin and mucous membranes, which are typically associated with antecedent medication use or infection. We review 108 cases of erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis from Texas Children's Hospital, Houston, Texas, from 1981 to 1991, and illustrate the characteristic skin and mucosal lesions. In addition, we describe in detail two unusual cases requiring intensive airway management. Head and neck manifestations were present in 4 of 79 patients (5%) with erythema multiforme and 26 of 28 patients (93%) with Stevens-Johnson syndrome. In Stevens-Johnson syndrome, mucosal involvement of the lip (93%), conjunctiva (82%), oral cavity (79%), and nose (36%) were most common. Antecedent medication use was identified in 59% of erythema multiforme patients and 68% of Stevens-Johnson syndrome patients. We note a striking increase in the number of cases in our series caused by cephalosporins. Fifty percent of Stevens-Johnson syndrome patients required supplemental hydration or alimentation because of the severity of the oral cavity involvement. The head and neck mucosal manifestations largely respond to local care, and the routine use of prophylactic antibiotics or systemic steroids is not recommended.

Cysteine peptidases (CPs) are phylogenetically ubiquitous enzymes that can be classified into clans of evolutionarily independent proteins based on the structural organization of the active site. In mammals, two of the major clans represented in the genome are: the CA clan, whose members share a structure and evolutionary history with papain; and the CD clan, which includes the legumains and caspases. This review focuses on the properties of these enzymes, with an emphasis on their potential roles in the oral cavity. The human genome encodes at least (but possibly no more than) 11 distinct enzymes, called cathepsins, that are members of the papain family C1A. Ten of these are present in rodents, which also carry additional genes encoding other cathepsins and cathepsin-like proteins. Human cathepsins are best known from the ubiquitously expressed lysosomal cathepsins B, H, and L, and dipeptidyl peptidase I (DPP I), which until recently were considered to mediate primarily “housekeeping” functions in the cell. However, mutations in DPP I have now been shown to underlie Papillon-Lefèvre syndrome and pre-pubertal periodontitis. Other cathepsins are involved in tissue-specific functions such as bone remodeling, but relatively little is known about the functions of several recently discovered enzymes. Collectively, CPs participate in multiple host systems that are active in health and in disease. They are involved in tissue remodeling and turnover of the extracellular matrix, immune system function, and modulation and alteration of cell function. Intracellularly, CPs function in diverse processes including normal protein turnover, antigen and proprotein processing, and apoptosis. Extracellularly, they can contribute directly to the degradation of foreign proteins and the extracellular matrix. However, CPs can also participate in proteolytic cascades that amplify the degradative capacity, potentially leading to pathological damage, and facilitating the penetration of tissues by cancer cells. We know relatively little regarding the role of human CPs in the oral cavity in health or disease. Most studies to date have focused on the potential use of the lysosomal enzymes as markers for periodontal disease activity. Human saliva contains high levels of cystatins, which are potent CP inhibitors. Although these proteins are presumed to serve a protective function, their in vivo targets are unknown, and it remains to be discovered whether they serve to control any human CP activity.
