Morphometric parameters of lower third molars at different stages of eruption and across age groups in subjects with undifferentiated connective tissue dysplasia
The aim of this research is to examine the morphometric parameters of lower third molars at different stages of eruption and across different age groups, as well as the prevalence of retention in the study participants with undifferentiated connective tissue dysplasia. Material and methods. The research included 327 women with and without undifferentiated connective tissue dysplasia (UCTD). Morphometric parameters were assessed using CBCT data obtained using Planmeca ProMax 3D s (Finland) with the OnDemand 3D software. The study examined the inclination of the lower third molars, mesiodistal and vestibulolingual dimensions, the crown length of the teeth, and the average crown length of the lower molar arch. Results. An analysis of the topographic position of the lower third molars revealed that medial inclination occurs in 32.4% of cases with UCTD and in 41.7% of cases without UCTD. Among the examined patients with UCTD, the following types of inclination were prevalent among positional anomalies: buccal (19% of cases), lingual (16.9%), and distoangular (15.5%). In patients with UCTD, horizontal inclination of the lower third molars was observed in 11.3% of cases. Among patients without UCTD, buccal (20.5% of cases) and distoangular (9.7%) types of inclination of the examined teeth predominate. It is important to note the high number of cases among examinees without UCTD who had a vertical inclination of the lower third molars (17.9% of cases); however, this number is lower among individuals with UCTD (2.8% of cases, p<0.001). Conclusions. A study of the position of the lower eighth teeth revealed that the following types of inclination predominate in patients with UCTD: medial, buccal, lingual, and distoangular. An analysis of the mean module in the lateral quadrant of the mandible revealed a decrease in this index for the lower sixth and seventh teeth with age in individuals with UCTD, which confirms the findings regarding a reduction in the primary massiveness of the first and second molars in UCTD.

DEVELOPMENT AND CLINICAL APPROVAL OF TECHNOLOGY TO SUPPORT MEDICAL DECISION-MAKING ON RISK ASSESSMENT OF DISEASES ASSOCIATED WITH THE ERUPTION OF LOWER THIRD MOLARS AND PURULENT-SEPTIC COMPLICATIONS
The aim is to describe the connective tissue mechanism of lower third molar eruption in normal conditions and in cases of connective tissue dysplasia, to develop and test a technology to support medical decision-making in assessing the risk of lower third molar eruption diseases and purulent-septic complications. Materials and Methods. The study involved 327 women who underwent clinical, radiological, microscopic, morphological, and biochemical examinations to determine the presence and degree of connective tissue dysplasia and to develop a description of the mechanism of lower third molar eruption. For clinical testing of the decision support technology, two groups of patients were selected: those with CTD (n=20) and those without CTD (n=20) diagnosed with acute pericoronitis, in whom the presence of clinical symptoms was assessed in the early postoperative period. Results. A conceptual description of the mechanism of eruption of lower third molars in connective tissue dysplasia was provided, which made it possible to develop and test a technology for supporting medical decision-making and criteria for establishing the risk of purulent-septic complications in cases of impaired eruption of lower third molars. The application of medical decision-making technology in the clinic for patients with connective tissue dysplasia made it possible to reduce pain syndrome by 1-2 days, general symptoms of intoxication by 3-4 days, and local manifestations by 5-6 days, which in many respects achieved a clinical effect similar to that in the control group (examined without CTD) in many respects, as well as preventing the development of purulent-septic complications in the early postoperative period. Conclusions. The developed mechanisms and technologies are aimed at understanding the causes of impaired eruption of lower third molars and provide a methodology for managing patients with this condition for timely diagnosis and prevention of purulent-septic complications.

FEATURES OF HUMORAL IMMUNE RESPONSE IN PATIENTS WITH VARIOUS FORMS OF PERICORONITIS AND CONNECTIVE TISSUE DYSPLASIA
Subject: indicators of the humoral immunity link, systemic and dental dysplastic manifestations. Objectives: to study the indices of the humoral immunity link of patients with various forms of pericoronitis and connective tissue dysplasia (CTD). Methodology. The study involved 327 women who were divided into two groups: with the presence of established connective tissue dysplasia (n = 142) and without it (n = 185). The humoral immunity in the examined women (30 with CTD and chronic pericoronitis, 30 with CTD and acute pericoronitis, 30 without CTD and chronic pericoronitis) was evaluated by determining immunoglobulins, CIC, C3- and C4-components of complement by radical immunodiffusion. Interleukin-6, interleukin-10 of blood plasma were evaluated by enzyme-linked immunosorbent assay. Results. It was found that immunologic changes in chronic pericoronitis against CTD background were manifested by increased concentration of CIC (198.52 ± 5.98, opt. den.), IgG (14.77 ± 1.23, g/l), decreased production of IgA (2.89 ± 0.27, g/l), IL-10 (12.72 ± 0.14, pg/ml) (p < 0.05). In acute pericoronitis against CTD background, the opposite immunologic picture was noted, associated with decreased concentration of serum CIC (123.85 ± 4.12, opt. den.) and decreased production of IgA (1.42 ± 0.05, g/l), IgG (11.87 ± 0.74, g/l), IL-10 (12.88 ± 0.28, pg/ml) (p < 0.05). Analyzing the frequency of early and late complications in acute pericoronitis, lower third molars eruption disorder in the postoperative period in the compared groups, their diversity was found to be greater in the group of the examined with connective tissue dysplasia (jaw alveolitis, jaw periostitis, bleeding (bulbous), phlegmons and abscess of the mouth area). Conclusions. The revealed immunologic abnormalities in the humoral link increase the risk of purulent-septic complications in the group with connective tissue dysplasia.

CHANGES IN MORPHOMETRIC AND DENSITOMETRIC INDICES OF THE MANDIBLE AT DIFFERENT STAGES OF LOWER THIRD MOLARS ERUPTION IN CONNECTIVE TISSUE DYSPLASIA
. The aim was to study the morphometric changes of permanent teeth and bone in the lateral mandible in normal and in connective tissue dysplasia (CTD). Materials and Methods. The study included 327 women who were divided into two groups (with DST, without DST) and five age subgroups (14-17, 18-21, 22-26, 27-31, 32-36 years). All participants were diagnosed with connective tissue dysplasia, radiologic examination, photodensitometry, crown modulus, average modulus of the molar row, mandibular morphotype, morphometric landmarks of mandibular variability, and its angular characteristics were determined. Results. The pronounced morphological changes in the lateral mandible in the group with DST are associated with an increase in the total mass of the crown part and an increase in the average module of the third molars, in the group without DST due to the massiveness of the crown part of the first and second molars and an increase in their average module. Morphometric indices of the mandible demonstrate multifaceted and multistage variability of bone structure during antenatal and postnatal exposure to aggressive factors on remodeling, blood supply, and innervation, which in turn negatively affects the maturation and eruption of teeth of the upper and lower jaws. Conclusions. Connective tissue dysplasia causes pronounced changes in morphometric parameters in the lateral section of the mandible, including due to high variability of the lower third molars, which has a key impact on the formation of a harmonious microenvironment and the possibility of proper eruption of such teeth.

ДИНАМИКА ВОСПАЛИТЕЛЬНОЙ РЕАКЦИИ В ПОДСЛИЗИСТОЙ ОСНОВЕ ДЕСНЫ И ТКАНИ ФОЛЛИКУЛА НА РАЗНЫХ ЭТАПАХ ПРОРЕЗЫВАНИЯ НИЖНИХ ТРЕТЬИХ МОЛЯРОВ ПРИ ДИСПЛАЗИИ СОЕДИНИТЕЛЬНОЙ ТКАНИ
Цель - изучить характер воспалительных реакций в подслизистой основе десны и ткани фолликула в процессе прорезывания нижних третьих моляров в норме и при дисплазии соединительной ткани в различные возрастные периоды. Материалы и методы. В исследовании приняли участие 327 женщин, которые были разделены на две группы (с ДСТ, без ДСТ) и пять возрастных подгрупп (14-17, 18-21, 22-26, 27-31, 32-36 лет). Всем участникам проводились удаление зубов 38, 48, забор фолликула и фрагмента десны над нижним третьим моляром. Проведены гистологическое исследование зубного фолликула и фрагмента десны после окрашивания альциановым синим, гемотаксилин-эозином, азур-II-эозином с помощью светового микроскопа для оценки степени выраженности и интенсивности воспалительных реакций в области прорезывающегося зуба. Результаты. Прорезывание нижних третьих моляров характеризуется изменением количество клеток воспалительного ряда в тканях фолликула и десны. В группе с дисплазией соединительной ткани обнаружено увеличение количества лейкоцитов и тучных клеток во всех возрастах. В группе без дисплазии соединительной ткани подобные морфологические изменения выражены только у молодых субъектов (14-17 лет, 18-21 лет). Результаты морфологического исследования подтверждают более выраженную клиническую картину при нарушении прорезывания нижних третьих моляров в группе с ДСТ: разлитая гиперемия, отек тканей, болевой синдром, симптомы общей интоксикации, гнойные формы отделяемого из-под «капюшона». Выводы. Усиление миграции лейкоцитов, тучных клеток вызывает сенсибилизацию организма с качественно новой ответной реакцией организма в виде выраженных клинических проявлений нарушения прорезывания нижних третьих моляров в группе с ДСТ.

ИЗМЕНЕНИЕ ОСТЕОГЕНЕЗА В НИЖНЕЙ ЧЕЛЮСТИ НА ЭТАПАХ ПРОРЕЗЫВАНИЯ ТРЕТЬИХ МОЛЯРОВ ПРИ ДИСПЛАЗИИ СОЕДИНИТЕЛЬНОЙ ТКАНИ
Цель - изучить динамику остеогенеза в нижней челюсти на этапах прорезывания третьих моляров в норме и при дисплазии соединительной ткани в различные возрастные периоды. Материалы и методы. В исследовании приняли участие 327 женщин, которые были разделены на две группы (с ДСТ, без ДСТ) и пять возрастных подгрупп (14-17, 18-21, 22-26, 27-31, 32-36 лет). Всем участникам проводились удаление зубов 38, 48, забор фрагментов кости нижней челюсти в области верхушечного отдела корневой части и коронковой части зуба 38 или 48. Проведены гистологическое исследование костных биоптатов, оценка денситометрической плотности кости нижней челюсти в области вершин корней и бугров, за коронковой частью нижнего третьего моляра по данным конусно-лучевой компьютерной томографии. Результаты. В норме остеобластный вал под нижним третьим моляром является опорой для выталкивания зуба к окклюзионной плоскости, в группе с дисплазией соединительной ткани такой механизм нарушен. Раннее прорезывание нижних третьих моляров при дисплазии соединительной ткани обусловлено выраженной резорбцией кости над их коронковой частью с нарушением формирования канала прорезывания, дополнительно в зоне прорезывания образуется большое количество костных дефектов, микротрещин, которые являются основой для развития воспалительных процессов, например, полулуний Вассмунда (костных карманов) еще на ранних стадиях прорезывания. Описанные морфологические изменения соответствуют рентгенологической картине, что подтверждается снижением денситометрической плотности кости в области нижних третьих моляров при дисплазии соединительной ткани на внутри- и внекостной стадиях прорезывания. Выводы. При дисплазии соединительной ткани возникает выраженный дисбаланс между процессами остеобластогенезом и остеокластогенезом на ранних стадиях прорезывания, что приводит к аномалиям прорезывания нижних третьих моляров.

Evaluation of the influence of connective tissue dysplasia on morphologic and biochemical rearrangements in the organic and mineral matrix of lower third molars at different stages of eruption
Цель работы — оценить зрелость твердых тканей нижних третьих моляров, находящихся на различных стадиях прорезывания, при дисплазии соединительной ткани (ДСТ), опираясь на результаты микроскопических и биохимических методов. В исследовании приняли участие 84 женщины в возрастных группах 14—17, 18—21, 22—26, 27—31, 32—36 лет с ДСТ и без нее, у которых по ортодонтическим или неотложным показаниям удаляли зубы 3.8, 4.8, находящиеся на разных стадиях прорезывания. После подготовки по собственным методикам образцов дентина, эмали и эмалево-дентинного соединения проводили микроскопическое исследование с помощью растрового электронного микроскопа Jeol JCM-5700, оценивали морфологию твердых тканей зуба на продольном срезе, а также выполняли биохимическое исследование методом ИК-спектроскопии, определяли на всех этапах положение и интенсивность полос поглощения (ПП). Между возрастными группами при ДСТ выявлены статистически значимые отличия в поверхностном отделе: в возрастной группе 22—26 лет на стадиях зачатка (p=0,0001), до уровня десны (p=0,02), до уровня коронки второго моляра (p=0,002); в возрастной группе 14—17 лет на стадии прорезывания до уровня коронки второго моляра (p=0,02). В глубоком отделе отличия уставлены только в возрасте 14—17 лет на стадии до уровня коронки второго моляра (p=0,02). Интенсивность ПП фосфатов (967 см−1) снижается при ДСТ на всех стадиях прорезывания, кроме стадии зачатка, однако именно в этой стадии также снижается интенсивность ПП 1050 см−1, что в целом свидетельствует о снижении содержания минеральной составляющей твердых тканей зубов при ДСТ. Интенсивность ПП коллагена (1202 и 1249 см−1) при ДСТ растет в дентине и снижается в эмали. Результаты микроскопического и биохимического исследования твердых тканей нижних третьих моляров показывают, что наличие коллагеновых волокон в дентине влияет на биохимические и механические свойства эмали через эмалево-дентинное соединение за счет прочного сцепления и правильной упаковки коллагеновых фибрилл. Purpose of the work is to evaluate the maturity of the hard tissues of the lower third molars at different stages of eruption in connective tissue dysplasia, based on the results of microscopic and biochemical methods. . The study involved 84 women in the age groups 14—17, 18—21, 22—26, 27—31, 32—36 years with and without connective tissue dysplasia who had teeth 38, 48, which were at different stages of eruption, extracted for orthodontic or emergency indications. After preparation of dentin, enamel and enamel-dentin junction samples according to our own methods, microscopic examination was carried out using a scanning electron microscope Jeol JCM-5700, the morphology of dental hard tissues was evaluated on a longitudinal section, as well as biochemical examination by IR spectroscopy, the position and intensity of absorption bands (AB) were determined at all stages. . Statistically significant differences between age groups in CTD were found in the superficial section: in the age group 22—26 years at the stages of rudiment (p=0.0001), up to the gingival level (p=0.02), up to the level of the crown of the second molar (p=0.002); in the age group 14—17 years at the stage of eruption up to the level of the crown of the second molar (p=0.0200). In the deep section, differences were established only at the age of 14—17 years at the stage up to the level of the crown of the second molar (p=0.0200). The intensity of AB phosphate (967 cm−1) decreases in CTD at all stages of eruption except for the rudimentary stage, but it is at this stage that the intensity of AB 1050 cm−1 also decreases, which generally indicates a decrease in the mineral content of dental hard tissues in CTD. The AB intensity of collagen (1202 and 1249 cm−1) in CTD increases in dentin and decreases in enamel. . The results of microscopic and biochemical examination of the hard tissues of lower third molars show that the presence of collagen fibers in dentin affects the biochemical and mechanical properties of enamel through enamel-dentin junction, due to strong adhesion and proper packing of collagen fibrils.

Open AccessEvaluation of the influence of connective tissue dysplasia on morphologic and biochemical rearrangements in the organic and mineral matrix of lower third molars at different stages of eruption
Цель работы — оценить зрелость твердых тканей нижних третьих моляров, находящихся на различных стадиях прорезывания, при дисплазии соединительной ткани (ДСТ), опираясь на результаты микроскопических и биохимических методов. В исследовании приняли участие 84 женщины в возрастных группах 14—17, 18—21, 22—26, 27—31, 32—36 лет с ДСТ и без нее, у которых по ортодонтическим или неотложным показаниям удаляли зубы 3.8, 4.8, находящиеся на разных стадиях прорезывания. После подготовки по собственным методикам образцов дентина, эмали и эмалево-дентинного соединения проводили микроскопическое исследование с помощью растрового электронного микроскопа Jeol JCM-5700, оценивали морфологию твердых тканей зуба на продольном срезе, а также выполняли биохимическое исследование методом ИК-спектроскопии, определяли на всех этапах положение и интенсивность полос поглощения (ПП). Между возрастными группами при ДСТ выявлены статистически значимые отличия в поверхностном отделе: в возрастной группе 22—26 лет на стадиях зачатка (p=0,0001), до уровня десны (p=0,02), до уровня коронки второго моляра (p=0,002); в возрастной группе 14—17 лет на стадии прорезывания до уровня коронки второго моляра (p=0,02). В глубоком отделе отличия уставлены только в возрасте 14—17 лет на стадии до уровня коронки второго моляра (p=0,02). Интенсивность ПП фосфатов (967 см−1) снижается при ДСТ на всех стадиях прорезывания, кроме стадии зачатка, однако именно в этой стадии также снижается интенсивность ПП 1050 см−1, что в целом свидетельствует о снижении содержания минеральной составляющей твердых тканей зубов при ДСТ.
