   <abstract xml:lang="ru">
    <p>Цель.  Уточнить влияние использования операционного микроскопа (ОМ) на отдаленный результат эндодонтического лечения.&#13;
Материалы и методы. 77 пациентов (94 зуба – моляры), возраст 19–70 лет, проходивших лечение по поводу осложненного кариеса, разделили на две группы: первая –  42 пациента (54 зуба), пролечили с использованием ОМ, вторая – 35 пациентов (40 зубов), без использования ОМ.  Фиксировали время, затраченное на лечение одного зуба, а также наличие или отсутствие минерализации полости зуба. Результаты оценивали через 6 и 12 месяцев клинически и с использованием конусно-лучевой компьютерной томографии. Статистическая значимость различий p &lt; 0,05.&#13;
Результаты. Успех лечения через 12 месяцев был выше при использовании ОМ, чем без него (91 % и 72 %, соответственно). Использование ОМ способствовало выявлению дополнительных мезио-буккальных каналов (MБ2) в молярах верхней челюсти (67 % и 19 %, соответственно), что увеличивало процент зубов с благоприятным исходом через год после эндодонтического лечения (p &lt; 0,001). Через 6 месяцев после лечения рентгенологически еще наблюдалась разница между диагнозами и наличием расширения периодонтальной щели, наличием периапикальных очагов и отсутствием изменений (p &lt; 0,05). Через 12 месяцев процент зубов без периапикальных изменений преобладал во всех группах. Разницы между поставленным диагнозом и исходом не выявили. Время, затраченное на лечение одного зуба с использованием ОМ, увеличивалось в среднем на 10 минут (p &lt; 0,05). Наличие минерализации полости зуба не влияло на исход лечения (p &gt; 0,05).  &#13;
Выводы. Использование ОМ увеличивает благоприятный исход лечения через год и увеличивает продолжительность лечения одного зуба на 10 минут. В молярах верхней челюсти МБ2 обнаруживаются чаще с ОМ. В случае, когда МБ2 не был найден, через 1 год после лечения выявлены периапикальные изменения в 88 % случаев.</p>

    <p>Aim. To clarify operating microscope (OM) usage on the long-term outcome after endodontic treatment. &#13;
Material and methods. Seventy-seven patients (94 molars), aged 19–70 years, undergoing treatment for complicated caries were divided into two groups: the first group, 42 patients (54 teeth), was treated with OM; the second group, 35 patients (40 teeth), was treated without OM. The time spent on treatment per tooth, as well as the presence or absence of pulp chamber calcification, was recorded. The results were assessed after 6 and 12 months clinically and using cone-beam computed tomography. Statistical differences was p &lt; 0.05.&#13;
Results. The treatment success after 12 months was higher with OM than without it (91 % and 72 %, respectively). The use of OM contributed to the detection of additional mesio-buccal canals (MB2) in the maxillary molars (67 % and 19 %, respectively), which increased the percentage of teeth with a favorable outcome one year after endodontic treatment (p &lt; 0.001). At 6 months after treatment, radiographically, a difference was still observed between the diagnoses and the presence of periodontal gap widening, the presence of periapical foci and the absence of changes (p &lt; 0.05). After 12 months, the percentage of teeth without periapical changes was predominant in all groups. No difference was found between the diagnosis and the outcome. The time spent on treatment of one tooth using OM increased by an average of 10 minutes (p &lt; 0.05). The presence of mineralization of the tooth cavity did not affect the treatment outcome (p &gt; 0.05).&#13;
Conclusion. OM usage increases the favorable treatment outcome after one year and increases the treatment time per tooth by 10 minutes. In maxillary molars, MB2 is more often found with OM. In cases where MB2 was not detected, periapical changes were detected in 88 % of cases one year after treatment.</p>
