Одонтома является доброкачественной одонтогенной опухолью, которая состоит из элементов зубных тканей. Диагностика и дифференциальная диагностика одонтом достаточно сложна из-за их большой гетерогенности и значительной морфологической неоднородности.</p><p>Описание клинического случая. В статье приведены результаты изучения морфологии и состава одонтомы, удаленной путем хирургического вмешательства по медицинским показаниям у пациента 7 лет, комплексом следующих методов исследования: оптическая микроскопия, растровая электронная микроскопия, рентгеновская компьютерная микротомография и рентгеноспектральный микрозондовый анализ. Установлено, что исследованная одонтома относится к твердым простым одонтомам. Одонтома имеет размер 0,93 х 0,63 х 0,45 см и образована дентином, покрытым неравномерным слоем эмали с неоднородной поверхностью. 3D-модель внутренней структуры одонтомы, полученная в результате микротомографии, демонстрирует коническую полость, образованную твердыми тканями зуба. Химический состав одонтомы содержит в значимых количествах кальций, фосфор, натрий, магний, хлор. Ca/P-коэффициент в дентине составляет 1,44, в эмали – 1,66-1,68.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты исследования вносят вклад в изучение этиопатогенеза одонтом и являются основой для диагностики и осуществления лечебно-профилактических мероприятий патологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. An odontoma is a benign odontogenic tumour that consists of dental tissue elements. Diagnosis and differential diagnosis of odontomas is complicated enough for their high heterogeneity and significant morphological inhomogeneity.</p><p>Clinical case description. The article presents the results of studying the morphology and composition of odontoma removed surgically for medical reasons in a 7-year-old patient using a complex of the following research methods: optical microscopy, scanning electron microscopy, X-ray computed microtomography and microprobe analysis. The study established that the odontoma belongs to solid simple odontoma. The odontoma is 0.93 х 0.63 х 0.45 cm in size and formed by dentin covered with an uneven layer of the irregular enamel surface. The microtomography provided the odontoma's internal structure 3D model demonstrating a conical cavity formed by the hard dental tissues. The chemical composition of odontoma contains significant amounts of calcium, phosphorus, sodium, magnesium, and chlorine. The Ca/P-coefficient in dentin is 1.44, and in enamel – 1.66-1.68.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study results contribute to the odontoma causes and pathogenesis investigation and form the base for the pathology diagnosis and implementation of treatment and preventive measures.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>одонтома</kwd><kwd>одонтогенное новообразование</kwd><kwd>эмаль</kwd><kwd>дентин</kwd><kwd>морфология</kwd><kwd>химический состав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>odontoma</kwd><kwd>odontogenic neoplasm</kwd><kwd>enamel</kwd><kwd>dentin</kwd><kwd>morphology</kwd><kwd>chemical composition</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">Soluk Tekkesin M, Pehlivan S, Olgac V, Aksakallı N, Alatli C.
