Повышенная стираемость зубов – заболевание, характеризующееся чрезмерной убылью твердых тканей прорезавшихся зубов, не связанное с физиологическим процессом. Отмечается рост распространенности этого заболевания в последние десятилетия. Причиной повышенной стираемости зубов в литературе часто указывают зубочелюстные аномалии, при этом редко отмечают влияние вида аномалии на отдельные зубы.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: установление взаимосвязи между видом зубочелюстной аномалии и степенью и характером повышенной стираемости зубов у детей в разных периодах формирования прикуса.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были проанализированы результаты обследования 266 пациентов в возрасте от 8 до 18 лет, не проходивших когда-либо ранее ортодонтического лечения. Ортодонтический диагноз ставился по классификации МКБ-10. Пациенты были разделены на группы в зависимости от периода формирования прикуса. Оценка повышенной стираемости проводилась по индексу TWI (только постоянные зубы). Степень повышенного стирания зубов определялась по максимальному баллу индекса TWI. Статистическая обработка данных проводилась в программе StatTech v. 2.5.6. Сравнения выполнялись с помощью критерия Краскела – Уоллиса (ANOVA), с помощью критерия хи-квадрат Пирсона, апостериорные сравнения – с помощью критерия Данна с поправкой Холма. Прогностическая модель разрабатывалась с помощью метода линейной регрессии.</p></sec><sec><title>Результаты</title><p>Результаты. У детей и подростков наблюдалась достаточно высокая распространенность повышенной стираемости зубов (у 69,2% был хотя бы один зуб с фасеткой стирания), степень стираемости увеличивалась с возрастом (коэффициент корреляции rxy = 0,674, p &lt; 0,001). Установлено, что частота развития повышенной</p><p>стираемости зубов при дистальной и глубокой окклюзии увеличивалась у резцов и клыков (p &lt; 0,001), при мезиальной окклюзии – моляров и премоляров, при открытом прикусе – моляров (p &lt; 0,001). Сочетание дистальной и глубокой окклюзии приводило к тяжелым формам повышенной стираемости зубов.</p></sec><sec><title>Выводы</title><p>Выводы. Результаты исследования показали, что при разных зубочелюстных аномалиях у пациентов отличаются паттерны стирания. Полученные данные помогут в разработке эффективных мер профилактики повышенной стираемости зубов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Abnormal tooth wear is a disease characterized by excessive loss of hard tissues of the erupted teeth, unrelated to the physiological process. This disease prevalence appears to have increased in recent decades. The literature often indicates malocclusion as the cause of abnormal tooth wear, though it rarely notes the impact of abnormality type on individual teeth.</p></sec><sec><title>Purpose</title><p>Purpose. The study aimed to establish the relationship between the abnormality type and the degree and nature of abnormal tooth wear in children at different stages of dentition development.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study analyzed the examination results of 266 patients aged 8 to 18 years without a history of previous orthodontic treatment. The orthodontic diagnosis was made based on the ICD-10. The patients formed the groups according to the stage of dentition development. The tooth wear index (TWI) (only permanent teeth) evaluated the abnormal tooth wear. The maximum TWI score determined the grade of abnormal tooth wear. The study statistically analyzed the data by StatTech v. 2.5.6, compared the data using the Kruskal – Wallis test (ANOVA) and Pearson chi-square, and made post hoc comparisons using Dunn’s test with Holm adjustment. The prognostic model was developed using the linear regression method.</p></sec><sec><title>Results</title><p>Results. The children and adolescents showed a sufficiently high prevalence of abnormal tooth wear (69.2% had at least one tooth with a tooth wear facet), tooth-wear grade increased with age (correlation coefficient rxy = 0.674, p &lt; 0.001). The risk of abnormal tooth wear in distal and deep occlusion appeared to increase at incisors and canines (p &lt; 0.001), in mesial occlusion - molars and premolars, in open bite – molars (p &lt; 0.001). The combination of distal and deep occlusion led to severe abnormal tooth wear.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study results showed that wear patterns differ in various types of malocclusions. The received data will help to develop effective measures to prevent abnormal tooth wear.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>зубочелюстные аномалии</kwd><kwd>повышенная стираемость зубов</kwd><kwd>подростки</kwd><kwd>детский возраст</kwd><kwd>твердые ткани зубов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>malocclusion</kwd><kwd>abnormal tooth wear</kwd><kwd>adolescents</kwd><kwd>child age</kwd><kwd>hard dental tissues.</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">Shellis RP, Addy M.
