Published: July 2024

ABSTRACT
Orthodontically induced external apical root resorption (OIEARR) is a common complication associated with orthodontic treatment, with genetic factors playing a significant role in its etiology. This article aimed to review the available literature on OIEARR and it is association with genetic polymorphisms. Various electronic databases were searched for cross-sectional, prospective, and retrospective longitudinal studies, randomized controlled trials, and reviews and meta-analyses to determine the impact of genetic polymorphism and OIEAAR only the articles available in English-language were included in the study. In conclusion, this narrative review provides evidence supporting the role of genetic polymorphisms in the susceptibility to OIEARR during orthodontic treatment, highlighting the importance of personalized treatment approaches and genetic screening in orthodontic practice. This revealed a significant association with specific genetic polymorphisms and the susceptibility to OIEARR. Further studies incorporating larger sample sizes and diverse populations are warranted to validate these findings and facilitate the development of targeted interventions for preventing or minimizing OIEARR in orthodontic patients.

ABSTRACT
A periodontal abscess is a localized, purulent infection involving a greater dimension of the gum tissue, extending apically and adjacent to a periodontal pocket. Representing 6%–14% of all dental emergencies, the third-most common dental emergency is the periodontal abscess. Classification of periodontal abscesses depends on their course, location, number, and etiological criteria. The etiology of the periodontal abscess has been directly associated with periodontitis or sites without the previous existence of periodontitis. The presence of local and systemic factors makes the patient vulnerable to a periodontal abscess. It has been reported that microorganisms, primarily Gram-negative anaerobic rods, colonize the periodontal abscess. The usual clinical features of the periodontal abscess are the presence of generalized periodontal disease with pocket and bone loss, commonly related to the vital tooth, swollen and tender, sinus opening, or pus discharge through the periodontal pocket. The periodontal abscess should be ruled out from similar conditions and lesions as periapical abscess, gingival abscess, endo-perio lesion, perio-endo lesion, root fracture, and cracked tooth syndrome. The periodontal abscess diagnosis is based on the chief complaint and the history of the present illness, clinical findings, and investigations. Periodontal abscess management is a combination of three stages: immediate management, initial management, and definitive therapy. Early diagnosis and immediate treatment are crucially important for periodontal abscess management, to prevent the loss of an involved tooth. In this case report, all aspects of the periodontal abscess are described.

Published: July 2024

The current research was conducted in 2020–2023 on the botanical-geographical plot “Steppes of Ukraine” at the M.M. Gryshko National Botanical Garden of the NAS of Ukraine and was focused on ripe fruits of Asparagus officinalis. This study aimed to find out the main statistical characteristics of morphometric traits of A. officinalis fruits: fruit diameter, number of locules per fruit, number of seeds per fruit, number of seeds per locule, and to confirm or deny the hypothesis of positive pairwise correlations of the first three traits. Eighteen combinations of four morphometric traits were found in the A. officinalis fruits. For each morphometric feature of A. officinalis fruits, ten statistical characteristics were determined: arithmetic mean, median, mode, range of variation, oscillation coefficient, standard deviation, coefficient of variation, standard error of the mean, coefficient of skewness, and coefficient of kurtosis. The coefficient of variation showed that the number of seeds per fruit is the most variable of the studied morphometric traits of A. officinalis fruits, and the fruit diameter is the least variable. According to the comprehensive assessment of the coefficients of skewness and kurtosis, the distributions of the number of seeds per fruit and the diameter of the fruits are closest to the normal distribution. It was established that the correlations between pairs of such traits as fruit diameter and number of locules per fruit, fruit diameter and number of seeds per fruit, number of locules per fruit and number of seeds per fruit are positive, direct, and strong. Thus, considering the economic feasibility, it is more practical to collect A. officinalis fruits of a larger size to obtain a larger number of seeds. The results of this work are of interest for the morphology and biometrics of A. officinalis and its cultivation.

Published: July 2024

The authors analyze pricing in the residential real estate market in Moscow and St. Petersburg – the largest cities of the Russian Federation in the article. The issue of the cost of residential real estate is one of the most important for the residents of Russian megapolises. Megapolicies are the largest centers of migration, both from other regions and from other countries. The population of such cities is expanding at a significant rate, and the construction industry is increasing the rate of creation of new real estate objects. Under such conditions, it is crucial to realize the dependence of real estate value and key externalities.Within the framework of the study, the authors rely on the works in the field of real estate valuation and statistical methodology. The group of authors puts forward statistical hypotheses about the impact of some factors, in particular the level of cumulative inflation, the key rate set by the Central Bank of the Russian Federation, the average level of wages in the region and the weighted average rate on mortgage loans to citizens on the formation of the weighted average cost per square meter of housing in Russian cities.The statistical method of factor analysis is used to assess the significance of each of the factor variables on the resulting parameter. Regression modeling allows estimating the degree of impact of significant factors on the cost per square meter of residential real estate. The models allow to assess the trends of changes in the cost of real estate on the primary and secondary residential real estate markets in Russian megacities, as well as provide an opportunity to consider the differentiation in the impact of each factor between different types of markets in different cities.The results of the study may be useful in building industry forecasts and developing government measures to support residential construction.
