“…Операція видалення зуба протягом тривалого часу є найбільш поширеним оперативним втручанням, проте наразі стоматологічна реабілітація таких пацієнтів є дуже актуальною, що обумовлено як функціональним, так й естетичним компонентом [2,8]. Важливою умовою для подальшого заміщення дефекту зубного ряду, в тому числі й за рахунок дентальної імплантаціїзбереження висоти альвеолярного паростку який зазнає суттєвого зниження після видалення зуба [3,10]. Тому питанню збереження кісткової тканини щелеп після проведення операції видалення зуба присвячена велика кількість наукових досліджень вітчизняних та зарубіжних авторів [1, 4,5].…”

Tooth extraction has long been the most common surgical procedure. Preserving the height of the alveolar ridge after extraction is crucial for further replacement of the missing tooth, including through dental implantation. This study aimed to assess the effect of cryopreserved placenta and quercetin on bone formation and osteoresorption markers in oral fluid. Ninety patients who underwent lower tooth extraction due to inflammation participated in the research. They were divided into three clinical groups of 30 each: the first group received cryopreserved placenta after extraction, the second group received combined therapy of cryopreserved placenta and quercetin, and the third (control) group underwent standard tooth extraction. Osteocalcin and matrix metalloproteinase-8 levels in the oral fluid were measured on days 1, 10, 20, 30, 90, and 180 after extraction for all groups. Antagonism between "osteocalcin" and "matrix metalloproteinase-8" was observed in the oral fluid during reparative osteogenesis. However, statistically significant changes in this marker were noted earlier in the observation period and were more pronounced, possibly due to local changes predominating. This suggests activation of bone tissue resorption processes in the early stages of the study and osteogenesis in the later stages of observation. The least dynamic changes in the studied indicators were observed when cryopreserved placenta was used in combination with quercetin treatment.

“…Мікроорганізми, що колонізують поверхню зубних імплантатів можуть утворювати біоплівки, що захищають їх мікроколо-нії від механічного впливу, антимікробних сполук та імунних факторів. На сучасному етапі профілактичне застосування антибіотиків при проведенні дентальної імплантації не справляє значного ефекту проти післяопераційної інфекції [1,5]. Але може чинити селекційний тиск на розвиток антимікробної резистентності.…”

Introduction: Microorganisms colonizing the surface of dental implants can form biofilms that protect their microcolonies from mechanical impact, antimicrobial compounds, and immune factors. Prophylactic use of antibiotics during dental implantation can exert selective pressure on the development of antimicrobial resistance. In this context, N-chlorotaurine (NCT) is a promising compound to combat resistant agents. The aim is to investigate the efficacy of NCT against pathogens associated with dental implant complications. Materials and methods. A buffered 1% NCT solution adjusted to pH 7.1 was used for the study. Multidrug-resistant cultures (MDR) were identified. Determination of NCT activity was carried out by the agar and suspension method. The results. After standard antibiotic susceptibility testing, cultures classified as MDR were selected. 12 cultures were included in the MDR group, including seven S. aureus, three K. pneumoniae and three A. baumannii. MDR cultures of S. aureus had MRSA profile. Production of carbapenemases was confirmed in all MDR K. pneumoniae isolates, 2 of them showed production of metallo-β-lactamases. MDR isolates A. baumannii were also producers of metallo-β-lactamases. All 12 investigated MDR cultures were sensitive to NCT, the diameter of the zones of growth retardation was at least 15 mm. No significant difference was found between the effectiveness of 1% NCT solution against microorganisms with different mechanisms of drug resistance (t-test, p>0.05). When conducting studies in a liquid environment, a 1% NCT solution showed similar results, all MDR cultures were sensitive and showed a decrease in the microbial load (CFU/ml) by at least 2 log10 steps already 15 minutes after the start of the study. Notably, there was no significant difference in the efficacy of NCT against conditionally susceptible and MDR agents. Conclusions. Reducing the threat and burden of MDR pathogens is one of the goals announced by WHO and the Centres for Disease Control. Our study clearly confirms that various antibiotic resistance mechanisms do not affect the bactericidal activity of NCT, making it promising for the treatment of resistant infections.

“…Dental implantation is a commonly used method of treatment in dentistry to replace defects in the dentition [1,2,3,4]. However, certain clinical conditions are required for its use [5,6]. Each implant can withstand a certain chewing load, which is determined by the area of the implant-bone contact.…”

Dental prosthetics with dental implants is the most modern method of treating patients with adentia. The advantage of this method is that it avoids the preparation of teeth located near the defect area, which means that the load on the existing teeth is within the physiological norm, preventing their premature loss. In clinical practice, when planning and implementing dental implants, the most common problem is bone atrophy in the area of surgery. According to statistical data, in the post-extraction area, the width of the alveolar part of the jaw decreases by an average of 50% of the original volume during the first year. The degree of atrophy varies depending on the location of the defect, the intensity of metabolic processes, individual characteristics of the body, the initial characteristics of the bone and inflammatory and destructive changes that often precede tooth extraction. In cases of significant atrophy, additional surgical procedures are required to increase the volume of bone tissue in order to create conditions for dental implantation.Using the scientific search method of research, the data from literature sources on modern methods of bone augmentation (open and closed sinus lift) were processed, and the possibility of improving the closed sinus lift was analysed.In the presence of significant bone atrophy in the intervention area, which occurs in most clinical cases, the open sinus lift technique is preferred despite certain difficulties in its application. In this regard, it is advisable to expand the indications for closed sinus lift by considering the individual clinical characteristics of the surgical intervention area, minimising the risk of xenograft infection, reducing the rehabilitation period and financial burden on the patient.Based on the analysed scientific publications, the socio-medical significance and ways of implementing the improvement of closed sinus lift to expand its indications are determined.
