[Sialotripsy as a treatment option for patients with salivary stone disease]. / Ispol'zovanie litotripsii dlya lecheniya patsientov, stradayushchikh slyunokamennoi bolezn'yu.

BACKGROUND: The pathologies of the salivary glands are very diverse. Salivary stone disease occupies a special place among diseases of the salivary glands of a non-neoplastic nature. The incidence of salivary stone disease is extremely extensive and accounts for up to 85% of all pathologies of the salivary glands. OBJECTIVE: Improvement of minimally invasive methods of treatment of salivary stone disease, which does not lead to excision of the gland. MATERIAL AND METHODS: On the basis of the Clinics of the Samara State Medical University of the Ministry of Health of Russia, in the period from 2010 to 2020, a clinical group was formed, consisting of 193 patients with salivary stone disease of various localization. The age of the patients ranged from 16 to 84 years. All patients were therapeutically examined at the preoperative stage, voluntary informed consent was signed. Shockwave sialotripsy was performed in 95 patients of the main group (in 64 patients the calculus was located in the submandibular salivary gland, in 31 patients - in the parotid salivary gland). For lithotripsy, we used a lithotripter apparatus «Edap¼ (France) and «Wolf¼ (Germany). RESULTS: The analysis of the results obtained as a result of the study made it possible to draw a conclusion about reasonably better results of removal of calculi in the ducts of the salivary glands using the lithotripter «Swiss LithoClast® Master¼ (Switzerland). At the first visit and the therapeutic effect of the lithotripter, all patients suffering from bouts of salivary colic showed complete cessation. CONCLUSION: Thus, our study, which was devoted to the study of the results of various methods of treating patients with salivary stone disease, showed that sialolithotripsy using special narrowly targeted devices for crushing and subsequent excretion of salivary calculi allows to achieve the best results at present.

[Evaluation of the species diversity of microflora isolated from the epithelium of the oral mucosa in patients using removable orthopedic structures based on dental implants]. / Otsenka vidovogo raznoobraziya mikroflory, vydelennoi s epiteliya slizistoi obolochki polosti rta, pri ispol'zovanii s"emnykh ortopedicheskikh konstruktsii s oporoi na dental'nye implantaty.

OBJECTIVE: To assess the species diversity of microorganisms isolated from the oral mucosa in patients with removable orthopedic structures based on dental implants. MATERIALS AND METHODS: The indicators of the species diversity of microorganisms isolated from the oral mucosa in patients of the main and control groups were studied. RESULTS: For prosthetic treatment of patients from main group we used a method of manufacturing an overlapping, frame prostheses supported by teeth and dental implants. The results turned out to be reliable for opportunistic microorganisms Streptococcus anginosus and representatives of the orange periodontopathogenic complex Streptococcus constellatus. CONCLUSION: Microbiological assessment indicates the effectiveness of prosthetic treatment and the use of Corega tablets.

[Use of oral fluid metabolic rates for the assessment of reparative osteogenesis after bone augmentation procedures].

The use of osteoplastic materials allows extending indications for dental implants placement by considerable alveolar bone atrophy. The aim of the study was to reveal bone tissue metabolites which can be used as early bone destruction markers after bone augmentation procedure before any radiological signs occur. For this purpose the content of osteocalcinum, C-telopeptides, alkaline phosphatase and lactate dehydrogenase was examined in oral fluid. The increase of osteocalcinum and C-telopeptides and decrease activity of alkaline phosphatase and lactate dehydrogenase in comparison with control represented the pattern specific for bone destruction.

[Differential-diagnostic features of combined periapical lesions].

The paper describes specific correlation of the clinical and molecular pathogenic features in various types of combined periapical lesions. Endodontic apical lesions combined with periodontal disease are characterized by specific radiological signs, shifts in oral fluid physical and chemical properties, the disruption of nitrogen metabolism, increased iron concentration, collagen disruption and impaired concentration ratio of calcium and phosphorous. General depression of immunoglobulin synthesis and increased concentration of cortisol and estradiol in oral fluid are also typical features of combined periapical lesions.

[Clinical-metabolic data base on chronic generalized parodontitis].

As the result of clinical-lab study of 40 oral fluid parameters in 176 patients new block of data was received disclosing key pathogenetic links of chronic generalized parodontitis (CGP) to which could be attributed endocrine dysfunction with cortisol level reduction and free thyroid hormones increase, enforcing prooxidant processes with multiple iron content increase. As the result of it molecules of medium mass were accumulated; protein spectrum, protein coupling capacity, content of collagenous C-peptide, osteocalcine, Ca, P and Mg were changing. In comprehensive CGP treatment due to Natursyl (lipophilic fraction of holy thistle) applications the disease clinical signs disappeared quicker and biochemical markers normalized.

[Improved stump inlay use in prosthetic stomatological clinic].

The article is devoted to treatment of 106 patients with considerable or complete destruction of teeth crowns with special prosthetic appliances. The autors analysed the causes of complications in the course of rehabilitation of 106 patients. Some modern stages worked out by the authors were tested and implemented.

[Evaluation of the clinical efficiency of allogenic lyophilized dura mater membrane in immediate and early delayed dental implantation]. / Otsenka klinicheskoi éffektivnosti primenenia membrany allogennoi liofilizirovannoi tverdoi mozgovoi obolochkoi pri neposredstvennoi i rannei otsrochennoi dental'noi implantatsii.

Immediate and early dental implantation helps timely restore the functional and cosmetic intactness of the maxillodental system. Seventy-four patients were operated on by these methods and 116 implants were inserted. The results were evaluated by common clinical, special computer-aided x-ray methods, and biopsy. Comparative studies proved that allogenic lyophilized dura mater membrane promoted recovery of the alveolar bone tissue structure and compactness, improved the implant osteointegration, and reduced the incidence of unfavorable outcomes.
