Стирание зубов является процессом убыли твердых тканей, идущим на протяжении всей жизни. Целью исследования явилось изучение размерных характеристик зубов у лиц зрелого возраста при разной степени стертости их твердых тканей. Объектом исследования послужили 204 человека мужского и женского пола в возрасте от 21 до 60 лет с разной степенью стертости твердых тканей зубов. На контрольно-диагностических моделях оценивали степень стертости зубов, измеряли высоту анатомической коронки, мезио-дистальный и вестибуло-лингвальный диаметры коронок зубов. В результате исследования установлено, что у взрослых людей лиц при разной степени стертости твердых тканей наблюдается снижение высоты анатомической коронки от зубов с I степенью стертости к зубам с III степенью стертости на 12-96%. Мезио-дистальный диаметр увеличивается от зубов с I степенью стертости к зубам со II степенью стертости на 2-9% и далее уменьшается у зубов с III степенью стертости на 6-20%. Вестибуло-лингвальный диаметр уменьшается по мере нарастания процесса стертости от зубов с I степенью к зубам с III степенью на 3-26%. В целом результаты исследования свидетельствуют о различиях размеров и формы зубов при разной степени стертости их твердых тканей. По результатам исследования ширина коронки зуба больше при II степени стертости, а толщина - при I степени. Превосходство мезио-дистальных размеров возможно объясняется тем, что границы измерений в связи с убылью твердых тканей при II степени стертости, проходят на уровне экватора клинической коронки. Эти результаты имеют приоритетный характер и описываются впервые. Стирание коронковой части проходит одновременно на зубах верхней и нижней челюстей, процесс протекает несимметрично, что может быть связано с парафункцией жевательных мышц.</p></abstract><trans-abstract xml:lang="en"><p>In recent years, there has been an increase in the number of people with an asymmetry of the maxillofacial region and an uneven position of the teeth. Dental erasing is a lifelong process of loss of hard tissue. The aim of the study was to study the dimensional characteristics of teeth in persons of mature age with different degrees of wear of their hard tissues. The object of the study was 204 men and women aged from 21 to 60 years old with varying degrees of the wear erasing of the hard tissues of the teeth. On control and diagnostic models, the degree of tooth erasing was assessed, the height of the anatomical crown, mesio-distal and vestibulo-lingual diameters of the crowns of the teeth were measured. As a result of the study, it was found that in adults with different degrees of erasing of hard tissues, there is a decrease in the height of the anatomical crown from teeth with I degree of erasing to teeth with III degree of erasing by 12-96%. The mesio-distal diameter increases from teeth with the process of the erasing of the grade I to teeth with of the grade II wear by 2-9% and then decreases in teeth with the erasing of III grade by 6-20%. The vestibulo-lingual diameter decreases as the process of the erasing increases from grade I teeth to grade III teeth by 3-26%. In general, the results of the study indicate differences in the size and shape of teeth with different degrees of the erasing and wear of their hard tissues. According to the results of the study, the width of the crown of the tooth is greater with the II degree of the wearing, and the thickness - with the I degree. The superiority of the mesio-distal dimensions is possibly explained by the fact that the measurement boundaries, due to the loss of hard tissues at the II degree of erasing, pass at the level of the equator of the clinical crown. These results have a priority character and are described for the first time. The erasing of the coronal part occurs simultaneously on the teeth of the upper and lower jaws, the process proceeds asymmetrically, which may be associated with the parafunction of the masticatory muscles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анатомия зубов</kwd><kwd>высота коронки</kwd><kwd>твердые ткани зуба</kwd><kwd>степень стираемости</kwd><kwd>морфометрия зубов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dental anatomy</kwd><kwd>crown height</kwd><kwd>hard tooth tissues</kwd><kwd>degree of erasing</kwd><kwd>morphometry of teeth</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Milosevic A.
